Motionflow Clearness

Here are the pictures of the impact of the 'Clearness' slider. It behaves the same way as on the W800C or the X850C, but the motion blur trail is longer on every pictures.

Can you compare the relative quality of this Sony X830C with the Samsung UN40JU6500? We watch mostly broadcast TV and on-demand programs, some sports, only occasional DVD movies, and no Blu-ray. There is some off-angle viewing.
The X830C is better for off-angle viewing, but it has worse contrast (and as a consequence of that, its black uniformity issues are exaggerated). It also has more motion blur. Straight-on, its picture quality isn't as good as that of the JU6500.
The main downside to the JU6500 is that it has judder when playing 24p content like DVDs, Blu-rays, and streaming movies.
If you watch lots of movies on demand, the X830C is a better choice. For TV, video games, and sports, the JU6500 has better in-axis picture than the X830C.

I just got this TV because I read here it could go to 120hz @ 1080p but I can't seem to get it to go past 60hz in Windows. Looking at the manual it says it will only do 60hz for PC input is there something I'm missing?
Windows won't necessarily detect that the TV support 120Hz. To get 120Hz on our PC, we had to create a custom resolution of 1080p/120Hz in the NVIDIA Control Panel. It would probably be the same if you are using a different brand of video card.

Have this TV improved at all since the review? I heard that there have been some updates to the firmware and that there have been significant improvements to the picture quality.
There was an update right around the time when we reviewed the TV. It improved the upscaling, and we scored the TV appropriately. Apart from that, there's no other element of the picture quality that would improve with an update.

Thanks for all the work you do! Looking specifically for PC monitor usage but above 50" would be really overkill. Looking mostly for gaming and video editing. Would the x830c be a good choice. I can get it for a really good price, but I've also been looking at the JU7100 which I have to pay retail for. Any suggestions? It would be a 400 dollar gap between the Sony 49x830c and the Samsung 50JU7100. Is the Samsung worth it? Thanks for your time!
The x830c is a good choice since it supports all the important modes for a PC monitor usage including 1080p at 120hz, something that the JU7100 won't be able to do. This is assuming you will always use it with the lights on, which masks its poor blacks. You can then save your money and get the Sony x830c.

How would you compare this to the Vizio M 4k Series that you recently reviewed? I just purchased it from Costco, and while I'm impressed by the quality, I'm not blown away.
The X830C is IPS, so it has worse contrast and a better viewing angle than the Vizio M. It also has poor black uniformity and reflects more light.
The M is better for people who sit directly in front of their TV, and the X830C is better for people who need a wider viewing angle.
5
If given the choice, would you choose this TV for $800, or a 2014 model Sony R380B for $325 (both in the 40" size) for a PC monitor/gaming TV?
We haven't reviewed the R380B, so we can't say how it compares. The X830C is a great pick for a monitor, though. It has good color capability, good performance, and its IPS panel is ideal for sitting up close.

Have you actually been able to verify that 4k with 4:4:4 @60hz works? I ask because I have seen a forum post with someone claiming it did not. Thanks for all of your research - very helpful.
Yes, we did verify it. Be sure to use the 'Game' or 'Graphics' picture mode, and then also enable the 'Enhanced' HDMI signal format.

I just got this TV. I'm using it mostly as a pc monitor. When trying to set it at 1080p and 120hz everything gets blurry. Is there a fix for this? It works flawlessly at 1080p and 60hz.
Set the picture mode to 'Graphics' or 'Game'.

Based on your recommendation, I have been using the XBR43X830C as a PC monitor. Any suggestions on picture settings for PC use?
Our recommended settings will work well. Just be sure to select the 'Game' or 'Graphics' picture mode instead of 'Custom.'

Coming from an HP LP3065 professional IPS display, I purchased a Philips BDM4065UC VA monitor for my PC. The contrast on this was measured elsewhere at about 5000:1, and has overall excellent reviews. I calibrated it with a ColorMunki Display from X-Rite. I have to admit, the picture is really great, but it doesn't have the same uniformity as the HP. The blacks however, are clearly better. I have considered trading for the 43" Sony X830C to get back some of the uniformity and wide color gamut. I have also considered the 40" Samsung JU7500, as maybe the curve would make for better angles. I do some occasional photo editing, but much more often movies and games. What are your thoughts when comparing these displays? Also, any chance you could do a review of the Philips? It is quite popular as a large format 4K display.
It would certainly be interesting to review PC monitors in the future but we have limited resources for now and still have a lot of TVs to review.
IPS doesn't mean better uniformity, especially for TVs. All our PC monitors at our offices are IPS, and they all have better uniformity than any LED TVs we reviewed (VA or IPS). Our 43" X830C doesn't have a good uniformity overall.
You will probably be happier with the Samsung JU7500 than the X830C, even if it is missing the wide color gamut. The blacks are way better, and the color loss at an angle is slightly reduced due to the curve. It also has a lower input lag and less motion blur.

Thanks for the great review! I'm interested in this TV as a possible PC monitor given that it can do 4:4:4 chroma. The 120Hz at 1080p isn't a bad option either for desktop uses like gaming. I am guessing that your review of the motion blur is done at the default 4k resolution? Is there any noticeable benefit in terms of motion blur for PC gaming w/ 1080p @ 120Hz? e.g., 120Hz PC signal vs. 120Hz image processing by the TV. Does that make sense? For the TVs that can do 120Hz at 1080p, if it makes any difference in the outcomes, it would be great to see that addressed in the reviews. Lastly, can this set do a PC setup of 1080p @ 120Hz w/ 4:4:4 chroma? I didn't see that specified so just wanted to verify. Thanks in advance!
Our motion blur test is done at 1080p but the result is based on pixels response time so even if the logo would appear differently, the pixels response time are the same and would result in the same score too. If you game at 120Hz then everything will be smoother and appear more defined. But the motion blur trail will be the same length. It's an interesting idea to show the logo running at that speed, but the resulting picture will look very similar to our motion interpolation test. The difference is less artifacts, but it doesn't show up in our logo pictures. Yes it can do 1080p@120Hz@4:4:4.

I am interested in the 43X830C since you have recommended it as a good PC monitor and it has a high viewing angle score of 42 degrees. However, I am very distracted by IPS glow and had previously returned three LG TVs a couple years ago that had good viewing angle ratings over 30 degrees but had bad IPS glow. Will this Sony TV be noticeably better with IPS glow since it is over 40 degrees? I know the measurement is for contrast drop and not IPS glow but I have no other stat I can use for comparison. OLED is still too big and expensive.
Pretty much all TVs have the same amount of IPS glow. We don't officially measure IPS glow yet though, maybe in the future.

Why is there a difference between the X830C vs X850C ratings in terms of picture quality, and mainly the contrast ratio? They have the same specifications for the display - both IPS panels?
The X850C is a VA TV, which is why it scores higher for contrast than the X830C, which is IPS. The X830C also has more motion blur, and we found that its weak contrast made what issues we could see with the black uniformity more noticeable, which brought the score down further.

Is Sony using an LG panel for the XBR43X830C, or is it from some other source?
It is really hard to find TVs in this size range that don't have the feet mounted at the outer edges of the TV. I refuse to buy new AV racks/furniture due to manufacturers' oversights into how their TVs are going to be set up. (Hello Vizio, LG, Sharp, etc. at least provide mounting options to move the feet inboard, if needed.)
I greatly appreciate your website and the thoroughness of your reviews.
Yes, it's very likely an LG panel.

How does the Sony 830c (49) compare with the Vizio M (50) or Samsung JU7100? I had a 60" M series but had to return it as it was slightly to big for my mounting area. It looked great though.
I swapped it out for the X830c, but can now get the JU7100 for only about $100 more. It's in a fairly bright room and will be used for sports, TV and Netflix. After comparing your 830c review with the 7100 review I'm tempted to swap.
Also, would the smaller M Series be comparable? I avoided that because it would have a 60 hz refresh rate in the smaller sizes, but couldn't tell any difference when looking at the two in the store. Thanks.
Of the bunch, the JU7100 is definitely the best choice. The better contrast and its ability to handle light are both great for your setup and uses.
The M-series is also a decent pick. The main way the 60 hz panel affects you is that you won't be able to interpolate 60 hz video, so if you'd prefer to save a little money, the Vizio M is also a good choice. It has a bit more blur than the other two, but that won't be very noticeable with sports. Its screen finish also isn't quite as good for bright rooms as is the JU7100's, but, again, it will be fine.

Hi, I noticed how the X830c sets are the only ones with IPS displays, I've been wanting to upgrade to a 49X30C from my current KDL-40W5100. After learning that IPS screens pretty much suck I'm at a in-pass, I work for best buy and can get a Sony TV for 50% retail, in this the 49X30C for $600. It is the only size in the model range that would work for me, I also want to purchase a 4K to use with my PS4. In this situation would the 49 still be worth it or are IPS screens that bad. Also do you know how the contrast and color would compare to my W5100?
We did not review the W5100 so we can't compare with this one. For the price you have, the X830c is worth it. Contrast may be low but it's reasonable input lag of 36.8 ms and it's good motion handling will make for a good gaming TV. It's worth mentioning too that IPS provides a great viewing angle.

I have had this TV for a couple days now and the picture is looking good for antenna and HDMI, but for any streaming video (Netflix, Vudu, etc.) I can't figure out how to get rid of the "soap opera effect". Is there a way to change streaming video picture settings?
Yes. While watching streaming contents, hit the 'Action Menu' button on the remote then navigate to 'Picture adjustments' - 'Advanced settings' - 'Motion' and turn off 'Motionflow'.

How does the x830c have a wide color gamut without triluminous?
This is an error. Thank you for pointing it out. 'BT.2020' color space cannot be selected on the x830c. The error has now been fixed.

Hello does this TV have HDR? I did see it on your usage ratings but not on the certain features above. Thanks.
No, this TV did not support HDR when it was reviewed. Since we don't have this TV anymore in our lab, it may have received and firmware update that added the HDR capability, but we cannot be 100% sure. But even if it is now HDR ready, it would not be a very good HDR TV since it does not have the wide color gamut, local dimming and a very high peak brightness.

All TVs that we test are subject to the same tests and the 'USAGE RATINGS' are base on those test results. So even if a TV is not HDR ready, the 'HDR RATINGS' will have some scores. Soon, we will have a dedicated section for HDR and it will be more clear whether a TV have HDR or not. For the moment, you have to refer to the 'Inputs Specifications', where it is specified if a TV support any of the specific HDR standard.

Any new info on the artifacting that occurs on these Sony TVs when running at 1080p 120Hz? Some users on the Sony forums have claimed to remove or mitigate the artifacts by changing the timing in Nvidia Control Panel.
The problem is still present unfortunately. We did some tests by changing the timing on the Nvidia control panel as other have tried on some forums and it did remove a lot of the artifact, but not completely.

Hi there! I'm in the market for a new TV and I get a pretty cool discount with Sony TV's. I get a 50 inch W800C for $500, a 55 inch W800C for $650 and a 49 inch X830C for $600. Between these three, what would you guys recommend for gaming? I would use this TV for Xbox One and Netflix mostly. I have a fairly dark room and sit around 6 feet away from my current TV. I'd love your input! Thanks for all the information you guys have.
You will get a much better picture quality with the w800c since the x830c use an IPS panel that produce gray blacks and low contrast. Since you already have a good price, get the 55".
We are not taking any more questions for this product because we no longer have it in our lab.
