The Sony A1E OLED TV is an excellent smart 4k TV that offers exceptional picture quality thanks to its perfectly deep and uniform blacks. It can produce a wide range of colors, which combined with its smooth gradients makes HDR content look great. Its motion capabilities are also excellent since no trails follow moving objects and flicker can be used to enhance clarity. Unfortunately, input lag is a bit high with a 1080p input, and the easel stand always sits on an incline.
The A1E looks impressive from the front due to the lack of a visible stand and minimalistic appearance. Unfortunately the TV does lean back at a fairly significant angle, but this isn't too noticeable after a while. All of the inputs and the controls are located on the stand of the TV, and so can be difficult to access depending on the TV placement.
The rear of the TV extends outwards and forms the stand. It supports the TV very well (the screen itself makes up the front part of the stand) but does require a larger table than many TVs of the same size.
Footprint of the 55" TV stand: 13.0" x 48.4"
The TV looks good from the back, with a fabric covered grill over the stand and built in speakers. This can be removed to reveal the inputs and wall mount. Unfortunately the body of the TV picks up lots of fingerprints on the reflective finish and the inputs are very difficult to access if the TV is against a wall.
Although the stand extend quite far out the back, it folds in when mounting the TV. When folded in it will stick out a bit from the wall, but not too much. It also sits back at an angle when stood up, but it doesn't take long to get used to. If wall mounted then this isn't an issue.
The A1E is a fairly cool TV, never getting more than a little warm to the touch. The thickest part of the TV is in the center, which is also the warmest part of the TV. There is also a lot of heat along the bottom edge, which may contain some panel circuitry producing heat.
The build quality of the A1E is great, and everything feels very premium. The TV can be a bit difficult to carry though, as the screen tends to flex if the stand isn't well supported.
The Sony A1E OLED TV has an impressive picture quality. The infinite contrast ratio and perfect black uniformity result in a superb dark room performance and with its high contrast, dark and bright scenes are displayed excellently. When set in a bright room, the performance is a bit less stellar, since the peak brightness is average at best even if it can deal pretty well with reflections. The wide viewing angle of the A1 makes it a perfect fit for those with a wide living room since the picture quality remains good even for those sitting far off center. The gray uniformity is also great and sports fans should be pleased since dirty screen effect won't be a problem. HDR on this Sony TV is excellent - both for HDR movies or for HDR games. With the high contrast, the wide color gamut and the high peak brightness, HDR content really stands out when compared with SDR content.
Like other OLED TVs, the Sony A1E has an infinite contrast ratio - when each pixel displays a 100% black color they are totally turned off and do not emit any light. The A1E is an excellent TV for watching movies in a totally dark room, producing deep dark scenes any light bleed normally associated with LED TVs.
On OLED TVs there is no need for a local dimming feature since it uses a different type of technology, where there is not backlight to light up the pixels. Here the pixels themselves emit light and are completely turned off when a true black color is displayed on the screen. The video is for reference only.
Decent SDR peak brightness. Most SDR content like our real scene test is not shown very brightly, because the TV's Automatic Brightness Limiter (ABL) dims the TV when a scene with high average brightness is shown. However bright highlights in dark scenes are more bright, as shown by our 2% and 10% white window tests, because the average brightness in those scenes is low.
When compared with its OLED rival, the LG C7, the A1E is noticeably less bright. Both have very similar brightness in our 2%, 10% and 25% tests, but the C7 is brighter in our real scene and larger window tests, suggesting that the A1E's ABL kicks in sooner than the C7's.
A plot of our brightness tests over time is shown here.
Update 10/03/2018: Retested the brightness after firmware PKG6.5629.0177NAA. The real scene and peak brightnesses are essentially unchanged (+/- 10 cd/m²), but the TV now dims more aggressively over time, sometimes dimming after just two minutes of static content, so most of our sustained brightness measurement are lower than they were before. The measurements have been updated, but the overall score didn't change significantly. You can see the plot over time here.
Decent HDR peak brightness. The highlight in our real scene test gets very bright, so the brightness in most HDR scenes will be shown accurately. However highlights in extremely bright scenes will be less bright than they should be, as shown by how dim our 50% and 100% white window tests are displayed. This is due to the TV's Automatic Brightness Limiter (ABL), which dims the TV when the average brightness of a scene is very high. A plot of our brightness tests over time is shown here. Overall the peak brightness is a bit less than the LG C7 in all tests, partly because the ABL is slightly more aggressive on the A1E.
The A1E is a bit brighter in the Vivid picture mode with the Neutral color temperature, as shown in this plot. Our normal testing is done in the Cinema Pro picture mode using our recommended settings (found here), because the Cinema Pro mode has the most accurate color reproduction for HDR.
When the 'X-tended Dynamic Range' option is disabled the TV's ABL is also disabled, so it remains at a very dim 130 cd/m2 no matter the content displayed, as shown in this plot.
Update 10/03/2018: Retested the brightness after firmware PKG6.5629.0177NAA. The real scene and peak 2% window are a little brighter and the 100% window is a little dimmer, but the rest of the peaks are essentially unchanged. The most significant difference is that the TV's dimming over time is now more aggressive, sometimes dimming after only one minute of static content, so most of our sustained brightness measurements are significantly lower than before. The measurements have been updated, but the overall score didn't change significantly. You can see the plot over time here.
The Gray uniformity of the Sony A1 is excellent. Looking at out 50% gray test picture, the picture looks pretty uniform which is great as the 50% gray is more representative of the normal TV content.
The 5% gray is also very good, but some faint vertical line are visible, but these are only visible in very dark rooms.
This is a very similar result when compared to the LG C7, but note that the gray uniformity is unit dependent and you may actually have a slightly better or worse gray uniformity, depending on your unit.
Wide viewing angle. Brightness only decreases a little at an angle, and the black level remains perfect; however colors do shift more significantly at an angle. Still this is a great TV for rooms with wide seating, as people sitting to the side of the TV will enjoy almost as good picture quality as people directly in front.
As with other OLED TVs reviewed before, the Sony A1 has a perfect black uniformity. This is because when the TV is displaying a perfectly black picture, the pixels are completely turned off and emit no light, which results in a black screen without any light bleed.
The A1E has a similar glossy finish to the LG C7 OLED. It works well to reduce the intensity of reflections and produces the same visible purple tint. This is common to most high-end TVs which are good at handling reflections.
The Sony A1E as a great accuracy out of the box and could be used as is by most people without a calibration. Looking at the white balance, we can see that the picture is a bit warm since it is missing a bit of blue, but even with this the dE is only of 3 which is very good for most people. The gamma is tracking very close to our desired goal of 2.2 and the colorspace is also very precise with only the blues and cyans being a bit more off than the other colors.
This TV, like the rest of the Sony line of TVs, comes with a 2 point and 10 point color calibration feature. The 2 and 10 point calibration is easy to use and we were able to bring down the white balance dE to a negligible dE of 0.4. The correction to the white balance flattens the gamma curve, even though the 30% and 40% were still a bit off as visible in the above picture. The Color dE was brought down to 1.57 from 1.95 but could not be corrected further, since this TV is lacking a proper color management system, as all other Sony TVs. Even with a lacking CMS, the final accuracy after calibration is excellent.
You can see our recommended settings here.
Low quality content such as DVDs are upscaled well. Some minor haloing artifacts are present and edges do appear a bit jagged but the image remains clear.
Cable and other 720p content looks good once upscaled. Some minor artifacts can be seen but details are preserved and the image isn't too soft.
Native 4k content looks great. No issues can be seen. Note that there are some moire artifacts caused by the camera which are not present on the screen.
Wide color gamut. The TV has excellent coverage of the DCI P3 gamut, and very good coverage of Rec 2020. It doesn't have great tracking of our target points but its tracking is better than a lot of other TVs. Deep colors in HDR content will be well represented.
Decent color volume. The TV struggles to make bright colors bright enough, perhaps due to the OLED panel's RGBW pixel structure; however OLED's perfect blacks help it bring its wide Rec 2020 color gamut to very dark colors.
The Rec 2020 color volume is extremely similar to that of the C7, which has a similar panel; however the DCI P3 color volume is worse than the C7's because the A1E's P3 color gamut narrows at low brightnesses, unlike its Rec 2020 gamut.
The Sony A1E does an amazing job at displaying our gradient test image. As you can see, no gradations can be noticed and overall the picture looks very smooth without any real tone problems and this on all 3 color and grayscale.
Note that this test was performed with the 'Smooth gradation' feature off to really showcase the native performance of this panel displaying our test gradient image.
The 'Smooth gradation' feature does an excellent job of smoothing 8-bit content by completely removing visible banding. We took some test pictures to show how effective is this feature by sending an 8-bit gradient image and turning on at each setting value the 'Smooth gradation' option. You can see how it looks set to Off, Low, Medium, or High.
The Sony OLED TV does present some image retention, like the LG C7 and other OLEDs we have tested. As you can see on our test picture taken right after the 10 minutes burn-in scene of our test clip, the Rtings logos are still clearly visible and stay visible even after 6 minutes of recovery. This test was performed with Sony's 'Pixel shift' setting enabled.
Note that there is a variation in temporary image retention between units.
OLED panels such as the A1E do have the possibility of experiencing burn in. You can see our investigation into this here.
Like other OLED TVs, the A1E has an RGBW pixel structure to increase the display brightness. This means not all of the sub-pixels are on at the same time.
The motion handling of the A1 is superb. The almost-perfect response time results in almost no visible blur. This can be improved even further using the 'MotionFlow' option to flicker the light output, clearing up persistence blur. Fans of motion interpolation can also interpolate content up to 120 fps, producing a strong soap opera effect. Unfortunately movies played from some sources such as cable experience some minor judder, but this isn't noticeable to most people.
The response time of the A1E is almost instantaneous, resulting in only a very short trail of persistence blur following fast moving objects. This is a similar result to other OLEDs such as the LG C7, but if you don't mind flicker then the A1 can improve this with flicker. Unfortunately this fast response time means that low frame rate content appears to stutter due to the lack of motion blur smoothing between frames. If you don't mind the soap opera effect, this can be improved using the motion interpolation features.
Like most OLEDs, the A1 doesn't flicker the image in order to dim; this means that motion on screen will look smooth and won't appear flickery, which is great. Some small flicker is detectable in our measurements, but shouldn't be noticeable in person.
Unlike the LG OLEDs we have tested, it is possible to add flicker which works well to clear up persistence blur with fast motion. To do so, set 'MotionFlow' to 'Custom' and 'Clearness' to 'High'. Unlike most Sony TVs the 'Clearness' option is either On ('High') or Off ('Low').
Update 05/08/2017: After further testing, it appears that BFI isn't functioning properly when showing 120 Hz content, including content interpolated to 120 Hz by motion interpolation. The TV instead replaces every second frame with a black one, effectively turning it into a 60hz refresh rate.
The A1 has a 120Hz panel which can interpolate lower frame rate content (adding the soap opera effect). To do so, set 'MotionFlow' to 'Custom' and increase the 'Smoothness' slider. For 30 fps content it is also necessary to set 'CineMotion' to 'Medium' or 'High'. There are significantly less artifacts than the C7 which has a buggy interpolation feature.
Unfortunately, the A1E does experience some stutter which is especially noticeable with low frame rate content such as 24p movies. This is a result of the almost instantaneous response time, which causes a static image to remain on the screen for almost the full frame duration.
The Sony A1 OLED TV can display 24p movies over 24p sources like DVDs and Blu-rays without judder. 24p movies playing via 60p or 60i sources like cable or satellite boxes are displayed without any judder with 'Motionflow' set to 'True Cinema' and 'CineMotion' set to 'High'.
Update 07/18/2017: The TV has been tested with the newest firmware update (PKG6.2648.0065NAA). The 24p playback remains the same.
Update 10/17/2017: With the latest firmware (PKG6.2669.0070NAA) the judder over 60Hz signals has been fixed.
This TV (as with other 2017 models) doesn't support a variable refresh rate.
The A1E supports all the common input signals, and should be able to play nearly any content. It has low input lag with a 4k signal, which should please most gamers; however it has a bit higher input lag with a 1080p signal, which may disappoint more competitive gamers. Note: Only HDMI ports 2 & 3 support full bandwidth, but HDMI port 3 is also the audio return channel. If you have a receiver which supports ARC and more than 1 device which requires the full bandwidth of HDMI then you might have some issues connecting all of your devices. In this case it may be best to connect your receiver using an optical (Toslink) cable.
The A1E has good input lag with a 4k signal, which should please most gamers; but it has a bit higher input lag with a 1080p signal, which may disappoint more competitive gamers. Both the Game and Graphics picture modes have the same input lag, and both support 4:4:4 color. All the Game mode input lag measurements are very similar to the X930E and Z9D but ~5 ms higher, even though all three use the same x1 Extreme processing engine.
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.
All the common input resolutions are supported. Only the Game and Graphics picture modes can properly show 4:4:4 color. 4K @ 60 Hz @ 4:4:4 or 4:2:2 color are only supported on HDMI inputs 2 and 3, and only when 'HDMI Enhanced Format' is enabled.
When using the TV as a PC monitor 1080p @ 60 Hz is listed as the default resolution. 1080p @ 120 Hz is shown properly without artifacts and without the jagged upscaling seen on the X900E, but it isn't listed as a possible resolution so it must be added as a custom resolution.
Update 05/08/2017: BFI does not work with a 120hz input.
Update 06/12/2018: A note for Xbox One X and Xbox One S owners: 1080p @ 120 Hz from the Xbox is only supported on this TV when the Xbox's connection type is changed from Auto-detect (Recommended) to HDMI: (Xbox > Settings > Display & sound > Video fidelity & overscan > Display > Connection > HDMI). Unfortunately in this mode 4k, HDR, 50 Hz and 24 Hz aren't possible, so this mode is only recommended when the higher refresh rate of 120 Hz is more important to you than these other features.
Update 06/18/2018: Correction, 24 Hz and 50 Hz are in fact possible with the Xbox's connection type set to HDMI.
There is no input for component video on the A1. Unfortunately no adapter is included in the box for the composite input (Video In), so an adapter such as this may be required.
Dolby Vision will be enabled in a future update. Update 01/23/2018: The update enabling Dolby Vision compatibility is now available.
The A1E's sound is much better than the average TV, but it has issues when listened close to max volume. Unlike most TVs, the sound is well directed, which is also a plus.
Good frequency response. The response is quite flat throughout, with some minor overemphasis on the midrange. It gets quite loud, and bass extension is quite good. As common with Sony TVs though, compression and aliasing are present at maximum volume.
While distortions levels are overall low, THD steeply rises to distracting levels at higher volumes. This isn't too big of a deal unless you plan to use your TV's speakers for a party.
The A1E runs Android TV, which is a bit more difficult to navigate than other smart platforms but also has access to the Google Play Store, which has more apps than many other platforms. The 'Action Menu' button on the remote helps to relieve the navigation problem by providing a quick list of common settings so the user doesn't have to navigate to the main settings app. The remote also has a microphone for voice search so content can be brought up directly, again without needing to navigate the interface.
There are no ads in the TV's main interface, though third party apps can still have ads. There is an option to opt out of personalized advertising for these ads.
The first row of the home screen is filled with suggested content. It is possible to disable all sources of suggested content until all that remains is a line saying "No recommendations available at this time". However after the TV is restarted some previously unlisted suggested content sources may appear, so the process of disabling sources must be repeated multiple times.
Most of the popular apps come preinstalled, such as Netflix, YouTube and Amazon Video. Many more apps can be downloaded from the included Google Play Store.
The remote is rather large with a dizzying array of buttons. Fortunately most commonly used buttons are clustered around the central navigation pad so they are within easy reach, except the input and power buttons which are at the top. Also at the top is the microphone button for voice search, which uses the microphone built into the remote.
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 remote score has been increased to reflect the new fuctionality.
