The Sony X900C 4k LED TV is very thin and has good color accuracy at an angle. However, the blacks are poor and not uniform, which means it is not a great choice in a dark room.

Our Verdict

7.4 Mixed Usage

If you can get past its poor blacks and uniformity, the Sony X900C is a good 4k TV that will look great in your living room. It maintains good color accuracy at an angle, has decent sound, and handles motion well.

The top half of the Sony X900C is extremely thin (only 0.5 cm / 0.20"). The bottom half is thicker, but still relatively thin compared to other TVs. It will look great in any room.

The 55" version (XBR-55X900C) almost didn't fit on our testing table. It is the widest stand that we have tested this year so far. If you don't have a wide table, and you don't want to mount the TV on your wall, you might consider buying a third party stand (VESA compatible) like this one to replace the original TV stand. The stand on the 65" can be placed in the middle, solving this issue.

It has an IPS panel, so the blacks aren't good. It also suffers from IPS glow, which makes the blacks 'move' when you change position.

Due to its IPS panel, the colors retain their saturation even off-axis. The screen only gets darker.

Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.

The uniformity is also sub par. The edges bleed a little bit of light. The extreme thinness of this TV means that kind of uniformity issue is to be expected.

The Sony X900C has passive 3D, which is great if you don't like the flickering of shutter 3D. Also, contrary to passive 1080p TVs, it can display the full 1080 lines of 3D Blu-rays. Note that if you sit too close, you will see a little bit of crosstalk on the sides of the screen.

In game or graphics mode, the 1080p input lag of the Sony X900C is 35.1ms, which is about the same as other 2015 Sony TVs. It is playable when using the motion interpolation feature.

Update 09/14/2016: When sending an HDR signal at an 1080p resolution, the input lag is 70.2ms.

Unfortunately, when an HDR signal is detected, the picture mode is automatically set to 'HDR Video' mode and cannot be change to game mode to have a lower input lag.

It is good for an overall PC monitor. Use game or graphics mode if you want chroma 4:4:4 or 1080p@120Hz.
As with other Sony TVs, little artifacts (flashing lines) are seen when a 1080p @ 120Hz signal is being displayed.

Update: With the new firmware update PKG2.463.0010NAB, This TV now supports 4k @ 60Hz @ 4:4:4. To enable this, go to Settings - External Inputs - HDMI Signal Format - Enhanced (new).

The TV gets plenty loud and has a decent low-end extension. The frequency response is OK up to moderate volumes. At maximum loudness the frequency response suffers a little bit, but it's still relatively consistent with lower volumes.

Smart OS Android

The Android TV OS is good overall, and it is constantly improving.

It loses a few points, though, because the included smart remote isn't very good (at least not as good as Samsung's or LG's), so browsing apps or the web is a bit harder.
