The Sony X900E is a great 4k TV that offers some of the best picture quality found in an LED TV. HDR content looks particularly good on this TV since it gets very bright, and it handles motion exceptionally well. Its only real downside is the degradation of the image when viewed at an angle.

This TV is currently our best Mid-Range 4k UHD TV.
Pros
  • Deep blacks
  • Bright, which is good for HDR
  • Very fluid motion
Cons

Sony X900E Design Picture
Curved : No

The X900E has a very typical Sony design, with a small stand that supports the TV well and a very functional appearance. There are slots at the rear of the stand for cable management, but overall the design is quite minimalist.  

Stand
Sony X900E Stand Picture

The metal stand supports the TV well and is very stable. It looks good, especially due to the tracks in each rear leg for cable management.

Footprint of the 55" TV stand: 10.2" x 19.8"

Back
Sony X900E Back Picture
Wall Mount : Vesa 300x300

The back of the TV is very simple, with metal and plastic panels. If wall mounted, some of the ports may be difficult to access.

Borders

Borders : 0.43" (1.1 cm)

The borders are quite thin, and look good.

Thickness

The X900E is a fairly cool TV, and should never feel hot to the touch. However its power brick does get warm, up to 45 °C, though this isn't hot enough to cause any problems.

The build quality is very good, all of the parts feel secure. The construction is very good with screws used to ensure good support.

Picture Quality

The Sony X900E has great picture quality. The excellent contrast ratio and good black uniformity results in good performance when viewed in a dark room. The X900E is also a good option for a bright room, since it has a high peak brightness and can handle reflections pretty well. It is best suited for people who sit directly in front, since when viewed from the side the picture quality degrades considerably. When it comes to HDR this TV is a great performer; it has a great HDR peak brightness, great color reproduction and when you add local dimming to the equation, you end up with a very good movie experience.

The native contrast ratio is very good on this Sony TV. With a ratio of around 5400, this is much better than the X930D. A high contrast ratio is crucial for good dark scenes performance while watching movies in a dark room.

Note that this test is done in SDR with local dimming off to showcase the true native contrast of the panel used in this TV. With local dimming set to high with the same test pattern, the contrast ratio was around 6500 with black level of around 0.015 cd/m², which is even better.

The local dimming feature is average on the Sony X900E. When set side by side with last year X930D, it is clearly an upgrade visually, and we recommend it for normal viewing. When set to maximum it can sometimes feel a bit aggressive. If you visually see that it too aggressive, you can set it to medium or low.

Excellent SDR peak brightness. With both 'Auto Local Dimming' and 'X-tended Dynamic Range' set to 'High', the X900e is able to make small areas like our 2% window very bright. The TV can't brighten larger areas as well as smaller areas but large areas are still very bright. The TV is able to maintain this high brightness indefinitely which is good.

The overall gray uniformity of the X900E is good. The 50% standard deviation is a bit higher than what would be considered a good value, and this is cause by the darker corners and the general unevenness near the frame of the TV. Luckily for sports fans there is not too much dirty screen effect, as the center of the display is pretty even.

As for the 5% uniformity, besides some brighter areas near the bottom corners there is not much to complain about which is great.

The X900E native black uniformity (whitout local dimming) is good and is similar to last year Sony X930D. Some clouding can be seen, especially near the corners, but with a standard deviation of 1.203, this is still a pretty good result.

With local dimming turned on, the result is equally good with a value of 1.014. This is a good sign that the local dimming is working well on the X900e

With local dimming turn on and with regular content, the faint clouding visible on our picture should not be noticeable.

Out of the box in the 'Custom' picture mode the calibration of the TV is excellent and could be used without any further adjustments. The white balance is slightly too warm, but even then the white balance dE is only 2.15 which is still a good score. The color accuracy is also good, with only the green tracking a bit worse than the other colors.

Calibration of the X900E is very easy and fast to do with the provided 2 and 10 points white balance calibration. The white balance was quickly brought to a negligible 0.25 dE, and the gamma curve was flattened to track more closely to the 2.2 value. The color space dE was brought down a bit, but since there is no color space management on this TV, we could not bring it down further. In any case, with a dE of 1.97 it is still an excellent result that is well under our good value of a dE of 3.

The X900E has decent color volume. It is able to show its wide color gamut at a range of brightness values, though it does struggle at the extreme ends of this range. Its color gamut for extremely bright colors is smaller than at moderate brightness, and its blue tinted black level also prevents it from accurately showing very dark deep color.

The Sony X900E has some image retention, which is pretty unusual for a TV with a VA panel. The retention is really faint and not as strong as seen on some IPS TVs. It is the first time we've seen image retention on a VA TV. Note that image retention is not a deal breaker in any way, but more a temporary annoyance, since it is not permanent.

Update 10/05/2017: We have retested the image retention on our replacement unit (see here) and there is only very faint retention. The result has been updated, but note that there may be some variance on a unit-by-unit basis.

Excellent motion handling. The TV's fast response time results in only a very small trail following moving objects which should be good even for fast content. The backlight does flicker at low levels, but at a high enough frequency that motion appears smooth. It is able to clear up the image with black frame insertion.

The backlight does use PWM to dim, but only at very low backlight levels (at a setting of 8/50 or below). It flickers at a relatively high frequency of 720 Hz so content appears quite smooth. It is possible to reduce the flicker frequency to 120Hz by increasing the 'Motionflow' -> 'Clearness' slider. This does help to clear up motion but not as well as the 60Hz flicker available on other TVs.

Very good input lag overall. In game or graphics mode the input lag is always lower than 35 ms, which should be good enough for all but the most competitive gamers. Outside of game or graphics mode though the input lag is quite high, making this TV unsuitable for gaming with interpolation enabled.

Update 05/23/2017: The TV has been retested after the update to Android TV 7.0 Nougat, and the input lag is unchanged.

Update 07/18/2017: The TV has been tested with the newest firmware update (PKG6.2648.0065NAA). The input lag remains the same.

Update 09/20/2017: Tested 1080p @ 120 Hz input lag using our new input lag tool. It is much faster than the 1080p @ 60 Hz input lag, likely due to the TV bypassing some processing when it detects such an unusual signal.

Update 11/10/2017: Retested input lag with the latest firmware (PKG6.2669.0070NAA); there was no significant change.

This TV supports all of the common input signals. Only HDMI inputs 2 and 3 are capable of showing 4k @ 60 Hz @ 4:2:2 or 4:4:4 color, and only when 'HDMI Enhanced Format' is enabled. 4:4:4 color is supported in both game and graphics mode.

Remarkably the TV also displayed a 1080p @ 120 Hz input without showing the vertical line artifacts seen on the X930D. However when displaying this resolution while in game or graphics mode only crude upscaling was done on the 1080p image, so the image looked almost as jagged as it would on a 1080p TV. Some people may prefer this look however because it retains most of the sharpness of the original image.

Poor harmonic distortion performance. The overall amount of distortion at 70dB is very low, however, just like most of the other Sony TVs we've measured, there is a big spike in the overall harmonic distortion as volume is increased and the TV is put under heavier loads.

Sony X900E Smart TV Picture
Smart OS : Android TV
Version : 6.0

The Sony X900E uses Android TV as its smart platform. Android TV tends to be more difficult to navigate than many other smart platforms, so the interface may take some getting used to. The 'Action Menu' button on the remote helps to relieve this problem by providing a quick list of popular settings so the user doesn't have to navigate to the main settings menu. However one strength of Android TV is the Google Play Store, which contains many many apps that can be downloaded on the TV to extend its functionality. The included remote is rather large with many buttons, and has a microphone for voice search, which works well.

Note that for readers watching 50Hz content (such as in Europe) there is a bug which causes some frames to be duplicated, skipped or repeated (see here).

The remote is fairly large and has a dizzying array of buttons, like the remotes of the X930D and X800D. The round arrow button pad is surrounded by a circle of other often used buttons, and serves as the centerpiece of the remote. There is a microphone in the remote for Voice Search, which works well.

Update 12/11/2017: Google Assistant has now been added to Android TV on Sony TVs, and it brings a lot of new features to the voice control: commands like 'open Netflix', 'switch to HDMI 1', 'pause video', 'how's the weather' and 'turn off TV' all work well, though commands to change picture settings like 'set the brightness to 20' and 'switch to Game mode' don't work.

The Android TV remote app has fewer features than the apps of some other smart platforms, but can still be useful.

Update 09/12/2017: Sony has an app called 'Video & TV SideView' that's better than the Android TV app in most ways. It adds a few features like launching both apps and inputs, and has three different remote modes, one being a mouse cursor on the TV. The score and data fields have been updated to reflect the Sony app.

There are three buttons on the back of the TV that allow changing the channel, volume and input. The center button selects either channel, volume or input while the (+) and (-) buttons increment the setting. The center button also serves as the power button and can power off the TV is it is held down for a few seconds.

Differences between Sizes and Variants

We tested the 55" (XBR55X900E). For the most part, we expect our review to be valid for the 49"(XBR49X900E), 65"(XBR65X900E), and 75"(XBR75X900E). Unlike the other sizes, the 75" variant has an internal power brick.

If someone comes across a different type of panel or if their Sony XBR-55X900E doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Bottom right: Samsung MU8000 (UN55MU8000).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Sony X900E offers a compelling package that is very competitive considering its price point. Picture quality is great, and its local dimming is a strong selling point.

Sony X930E
55" 65"

The X930E is a higher-end Sony TV that performs very similarly to the X900E. It's a better TV overall, with a better local dimming and much higher brightness levels, but it's hard to recommend over the X900E since the price difference is fairly large.

Vizio P Series 2016
50" 55" 65" 75"

The Vizio P Series 2016 had the best local dimming we tested last year and will offer slightly better picture quality in a dark room than the Sony. The X900E is a better pick for watching TV shows and sports, however, thanks to its superior upscaling and more adjustable motion settings. This makes it a safer choice over the Vizio for those that are planning to use their TV for a variety of uses. Note that the 55 inch version of the Vizio P has a different type of panel that will perform worse in most of our tests.

LG UH8500
55" 60" 65" 75"

The LG UH8500 is a rarely seen recommendation and when compared to the X900E, it falls short in almost every front. The X900E will be a much better pick with the exception of watching the TV from an angle. Most people should buy the Sony X900E.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 was our top recommended TV last year and, if you can still find it in stores, will be a slightly better choice over the X900E. Its blacks are deeper and even more uniform, and it's able to produce colors that are even more saturated. Most people will be pleased with either TV, but the KS8000 is a slightly better pick since it is cheaper.

Additional Review Notes #2
Update 06/26/2017: Our 55X900E has developed an issue where regularly spaced red sub-pixels flicker on completely black scenes (approximately 8 sub-pixels are visible). The issue reduces in intensity after running a flashing pattern over the problem areas (such as this), but remains faintly visible. The TV otherwise functions normally, so we will continue to use this unit for testing new firmware versions. Please let us know if anyone else experiences this issue.

Update 08/10/2017: The issue has become worse, and so we have started the warranty process with Sony.

Update 08/14/2017: We have returned our old X900E unit and received a refurbished model through Sony support.

Do all variants of this model have VA panel?

At the moment we don't have any information about the other sizes besides the one we have reviewed. We will update the review as soon that we get the information about the other sizes.

Update 04/17/2017: A reader has confirmed the 49" variation has a VA panel.

41
Why does the X930E have better local dimming? I mean — how is it even possible. The X900E has a full array backlight, X930E is still edge lit.
The X930E has a very interesting backlight system. It's edge lit but it has multiple layers in its backlight diffuser that direct light to different zones of the screen, so it can produce local dimming that looks like full array, despite being edge lit.
38
Do only certain ports support HDR? I just read that on the AVS forums but I'm not sure if it's true. If it is true, is there a port that supports both HDR and also CEC?
All the ports support CEC and HDR, but only ports 2 & 3 are full bandwidth. This isn't a problem unless you're using it for gaming at 60hz (like on an Xbox one S or PS4 Pro).
31
Did the 120hz signal present artifacts like previous 120hz capable Sony tv's?
We did not see any artifacts like we saw on the previous year models.

Additional Review Notes

When in the graphics picture mode 1080p is displayed with very basic upscaling, just mapping one pixel to four. This is shown in the pixel picture to the right. This kind of upscaling looks more jagged but it retains all the sharpness of the original image, unlike the softer upscaling from the other picture modes. However 1080p @ 120 Hz does not show the same behavior; in both game and graphics modes it uses a different jagged upscaling that is a little softer, but is still more jagged than normal.

25
I just picked up the 75" X900E at Bestbuy and it has no power brick like the massive one the X930D had. It must be internal on this screen size for the X900E.
Thank you for the information. The review has been updated to mention this.
23
Was the 1920x1080 @120hz automatically detected in the Nvidia control panel or did you have to create a custom resolution like before?
We had to create a custom resolution.
19
How does the 2017 X900E compare to the 2016 X930D?
They are very similar, the X900E has better blacks, local dimming and input lag, but the 2016 X930D gets brighter. The X900E is a better TV, but it might not be worth the extra money.
18
Why does Sony always seem to have more input lag? Last year's Vizio VA panels had literally HALF the input lag of these Sony models per your own reviews. Is there any chance of finding a TV this year 50 inch or less that's 120hz, FALD, AND under 20ms input lag? 120hz models between 40 and 50 inch always seem to be extremely rare to begin with, and it pisses me off that people who prefer these screen sizes always get the short end of the stick when it comes to premium options. :(
TVs with under 20ms of input lag are quite rare nowadays, we've only tested a handful of Vizio and LG TVs to have it. Sony indeed isn't the best regarding input lag, but it definitely seems like they have listened to their customers' complaints since it is definitely lower this year on the X930E.
14
Is there much blooming/haloing with specular highlights? Can you confirm the X900E does not and will not support Dolby Vision? Thank you!
The TV does produce some blooming when displaying our test pattern, but this is mostly visible on a black background and shouldn't be a big issue in most scenes. The X900E does not support Dolby vision since only Sony TVs with the x1 Extreme chip are compatible with it. The X900E only sport the x1 chip, on which Dolby Vision is not supported.
14
I have a quick comment, so I've been following this page for awhile, and I don't know if this is something you've been doing recently or if your now paid by companies. But you're the "first" professional reviewers that I've ever seen turn off local dimming and take measurements with it off. I've never seen this. Even as biased as other reviewers are toward OLED they still try and match LED to their best setting. So I ask why do you do this? I've never heard of local dimming being aggressive. This isn't like turning on soap opera effect where objects glide.
We do recommend turning on local dimming, as you can see in our recommended settings. For some tests we turn it off to isolate a certain aspect of the picture quality and just it's individual performance. Aggressive local dimming is when a TV darkens the whole screen in order to prevent blooming. This results in less bright/vivid highlights.
13
I'm thinking about a Sony X900E or X930E or a similar model tier Samsung for a decent upgrade from a Sony 55X850C that has a real good panel as those go and isn't a bad TV but could be brighter on SDR and HDR. My objectives are the usual good color volume, details, blacks and shadow details, color pop and more specifically significantly more HDR/SDR brightness and brightness peaks which is my main concern for upgrading. I would like to know if any of these TV would be a substantial upgrade from what I have and more specifically the Sony X850C to Sony X900E and X930E and how big is the gap subjectively from X850C to X900E/X930E and X900E to X930E in this scenario best regards
The Sony X850C is still a good TV today. Both of the newer Sony TVs get brighter, have a better native contrast ratio and a good local dimming feature that the X850C lacks. The picture quality is overall better, especially with the X930E, since its HDR peak brightness will help a lot with dynamic range. We haven't tested the color volume of the X850C, but since it correlates quite closely with gamut, we can expect it not to be much worse than the current TVs. Overall, the X930E would be the most substantial upgrade, but the value of it is mostly in HDR.
13
I found this TV on Amazon, and someone asked what type of panel it had, and the manufacturer said it was a IPS, but on here it says it has a VA panel so which is it?
The model we have tested is a VA type LCD. We can't say for sure whether this applies to all sizes, but we don't expect it to be different.
13
I was wondering if you can add a picture of the power brick. Thanks!
The review has been updated with a picture of the power brick in the In The Box section.

The Sony X900E appears to have scored better than the Q7F in several important measures of picture quality and motion while being a better TV to use as a PC monitor. Given a 65" size, and primary use for watching TV shows and gaming using a PC, would you recommend the X900E over the Q7F?
Yes, go with the Sony X900E. Overall the Sony X900E has a better picture quality and will also have an edge for PC gaming because you can use the 1080p @ 120Hz resolution, which will give you a much better gaming experience than on the Q7F. The benefit of the 1080p @ 120Hz resolution are more important than the better input lag of the Samsung Q7F.
13
Thanks for the review on this 2017 Sony and its nice to see an improvement from last years model, where as Samsung with all their hype about QLED is actually not an improvement per your expert review. I assume the 49" model will also have a 120 Hz VA panel? Also what is the main advantage of the X900E's full array backlight compared to the KS8000's edge lit from 2016?

We haven't tested the 49" X900E but we believe it has a similar 120 Hz VA panel to the 55" we reviewed. The X900E's full array backlight provides much better local dimming than the KS8000's relatively crude edge lit local dimming. Though note that full array local dimming isn't always better than edge lit, the X930E's edge lit local dimming is better than the X900E's full array.

Update 04/17/2017: A reader has confirmed the 49" model has a 120Hz VA panel.

13
Im in doubt to buy the older X930D (1400 dollars) or buy the X900E (2100 dollars), is the 700 dollar difference worth it and recommend the X900E over the X930D?
Depending on your usage, it might be worth it. The biggest advantages the X900E have over the X930D are the significantly better blacks and better input lag. If your usage is mostly in brighter conditions and with limited gaming usage, then the X930D will suit you fine. Otherwise, it might be worth considering the X900E.
13
I have a single PS4 Pro I use for both games and Blu-ray movies. I configured the input using your recommended settings in game picture mode. If I leave it in game mode will I be getting a lesser experience when watching a Blu-ray movie?
You should get pretty much the same picture quality, except without any motion interpolation (or soap opera effect) and with some judder. That is because the Motionflow's 'Smoothness' and 'CineMotion' can't be turned on. For the rest, just to copy all the other available settings as they are in the custom picture mode.
12
Would the SOE be more pronounced on the X900E series at 120Hz vs the X800E at 60Hz? I am looking for no SOE, or the ability to reduce it as much as possible. I had the X930D and was unable to get rid of it for the internal Netflix app even with recommended settings to eliminate it.
The Soap Opera Effect (SOE, also called Motion Interpolation) should be disabled completely on Sony TVs when 'Motionflow' is set to 'Off' or 'TrueCinema'. 120 Hz TVs will have stronger SOE when it's enabled, but it could be disabled completely on every TV we've tested. It's possible the TV was in another picture mode when Netflix was playing. While Netflix is playing a video you can open the picture settings using the 'Action Menu' and set 'Motionflow' to 'Off' or 'TrueCinema' for Netflix.
11
I have several questions regarding 1080p @ 120 Hz. Is that at 4:4:4? What's the input lag? Is it possible to enable HDR? And finally, generally speaking, how is HDR mode activated? Automatically? Is there a manual method? Are there separate settings specifically for HDR?
We tested 1080p @ 120 Hz with RGB color and it passed our 4:4:4 test (showed the test image without artifacts). We measure input lag with the industry standard Leo Bodnar tool, which is unfortunately limited to 60Hz, so we haven't tested the 120Hz input lag. Expect it to be lower than the 60Hz input lag. HDR does work at 120 Hz on this TV. HDR is enabled by sending metadata to the TV, which will recognize it automatically and switch to HDR mode. We mostly recommend the same settings for HDR as for SDR, but there are some HDR specific settings. You can see our recommended settings here.

I see the input lag significantly improved over the 930D. Is this due to the new firmware Sony inemented in this TV or is it because of the improved processor in it? My question is, will Sony finally fix the input lag with the 930D and 940D models?
It may be possible that Sony implemented most of their fixes through software, but we cannot know if those can be implemented on older models as well. The X930E is definitely using a more up to date version of android, but we don't expect the marshmallow update to change the input lag since it did not on the 2015 Sony TVs.

I decided to bring the Q9F back. I think such an expensive TV should not have that degree of uniformity (Samsungs price is 5.000€). My choice fell onto the Sony KD-65 XE9005. I unboxed it yesterday. The picture is much better and worth the money (Sonys price: 2.200€). But the handling is a mass. First setup took me over 90 minutes (< 20 minutes at Q9F including smart hub personalisation). First picture you see is: "Please choose your language". The Samsung started with an overwhelming QLED-Video. The system menue laggs. When I switch picture settings while a video is running, the video starts lagging. BUT - the overall system performance is okay. You can open apps with voice control, which is fine. Once the TV is running you can enjoy a great picture. It's pretty uniform, both black and gray. Cable handling is also okay, even though there is no "One Connect Box". Unfortunately I need a longer LAN cable now.

I will switch back to Samsung's High End design and customer experience, as soon as the picture is worth the money.

Thank you for sharing your feedback, I'm glad you are enjoying your new TV. Unfortunately Android on the Sony TVs does allow a lot of flexibility and a huge selection of apps, but it is more difficult to use and often feels laggy.

You answered a question regarding auto-detection of the 120hz signal in another persons question. I would like to extend that question. Once the 120hz setting is added in the Nvidia control panel, will the tv auto switch based on the source? I am basically hoping it will act like a monitor and the source will drive the resolution. I plan to use this via PC for nearly all content (Netflix, Games, YouTube, etc). Extend this question to their SmartFeature apps to pc and back? Thanks.
Yes, the display will change its refresh rate based on the source, since the change is being made on the computer itself and not the TV (you essentially send a signal that TV doesn't state it supports). This means that the TV's internal smart features or input of another device will still play at the TV's native/expected refresh rate, even if you've used it with a PC at 120 Hz previously.

Even within the same PC, the applications themselves can dictate the monitor's refresh rate if they are executed in the exclusive fullscreen mode (This is how games and local video players usually work). You might want to change the refresh rate manually for web-based content which doesn't use this feature, but since 120 is a direct multiple of 24, 30 and 60 Hz, it should not be necessary to do so to enjoy it without encountering frame-rate related artifacts.

Have you - in your reviews of the XE900 series - noticed any major motion artefacts (with Motionflow disabled) on 50/59.94Hz native content? (i.e. not 23.976/24 or 25p acquired stuff - but 50/59.94Hz stuff like entertainment, sports etc.) My 49XE9005 and another model I've tested are both suffering badly from frame drops and out-of-order frame pair repeats (in 720p50 or 720p59.94 domain). I've tested two TVs - and compared them with a 49X8505B previous generation model with the same test material fed via an HDMI splitter.

The test material has burned in 720p50 timecode - and I have filmed it in 720p240 slow motion for analysis using an iPhone. It is clear to see that frames are being dropped (usually on shot changes) or shown for just 1/100th of a second instead of 1/50th in some cases. These are not hugely visible to the naked eye. However these drops are having to take place because of the repetition of pairs of frames - which most definitely ARE very visible.

Example :
Frame sequence 1, 2, 3, 2, 3, 4, 5...... N, N+3
The judder of seeing frames 2 and 3 repeated after they've already been seen is really clear (it is often after shot changes - but you can still see it a a judder). The dropping of Frames N+1 and N+2 is less obvious as it is usually on a shot change as well.

It's consistent across multiple TVs with the same settings - and happens usually at the same timecode.

Thank you for contacting us and letting us know.

That’s certainly very interesting. I was able to recreate the same frame drops and cadence issues on our 55” X900E. What’s also interesting is that it appears to be specific to the X900E (our X850E and X930E don’t appear to show the same issues).

This was tested in the ‘Custom’ picture mode both with ‘MotionFlow’ set to ‘TrueCinema’ and ‘Disabled’. The issue doesn’t appear to be present when in the ‘Game’ picture mode which suggests it is some additional processing that can’t be disabled in certain picture modes.

Is there an update on the refurb one? Has the same issue re-occurred?
Thank you for your question. Our refurbished unit did not show the issue which appeared on our first unit. Furthermore, it was less prone to image retention.

Hello guys great site! Keep it up! I'm not sure about your take on SOE (Frame interpolation) on 60Hz vs 120Hz TVs. Let's take a 24p movie for example. A 60Hz TV would have to create a total of 60 interpolated frames per second, since 60 isn't a multiple of 24. So we get a total of 60 artificially produced frames... Since 120 is a multiple of 24, a 120HZ tv will keep the original 24 frames and create 4 interpolated frames between each original image. We end up with 96 artificial frames + 24 original frames. The presence of the original images usually lessens the SOE effect to some degree as it keeps ALL image detail. Why do you state 120Hz TVs will have stronger SOE? Just curious... ;) Thanks! P.S. I use a PC connected to my TV and decode my videos with both MadVR (video scaler & renderer) and SVP (a software interpolation plugin). If you don't know them already, I'm sure you would love them... Options a plenty for the video freaks in you!
In general, what we mean by stronger SOE is smoother motion, not necessarily more interpolated frames. To respond to your question more specifically though, 60 Hz TVs do not usually interpolate 24p content to their maximum, but instead merely double the refresh rate to 48 Hz (modern TVs can adjust their framerate to match the source) and interpolate every other frame of the content. This means that, as you said, a 120 Hz TV will create four interpolated frames per original frame, while a 60 Hz TV will only produce a single interpolated frame, thus producing a much more pronounced SOE.

Have you guys heard/experienced the issue with the X900E, where the TV is unresponsive to being turned on by the remote? To resolve the issue, you have to disconnect the power, wait a few seconds, and reconnect the power. I did some Googling, and it seems like there's a lot of people having this issue. Since I honestly feel you guys are just about the only people who can get enough attention on it to get it fixed (or heck, maybe you guys know what's wrong), I wanted to run it by you.
Thank you for contacting us. We've experienced this issue on older Sony models before (2016 and earlier) but not on the X900E or other 2017 models. Sometimes changing the batteries on the remote or unplugging the TV can fix it, but we don't know what it's caused by. If any others readers are experiencing this issue, then please do let us know.
