This tv was replaced by the Sony X830F

Type : LED
Resolution : 4k
Refresh Rate : 120 Hz

The Sony X830C doesn't have good picture quality. It reflects too much light in a bright room, and with the lights turned off, the blacks are gray. At least it maintains good color accuracy when viewed at an angle.

Both the Sony XBR43X830C and the XBR49X830C have an IPS panel. The contrast ratio is really low, which means they're poor choices for a dark room.

The colors are great when you view them off-axis. You will perceive the same picture quality even when you're sitting at quite a wide angle.

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.

There was no significant clouding or flashlighting issue with our set. However, due to the poor blacks, every small issue is aggravated.

With the latest firmware update, 480p content look good and is not too soft.

Like most of Sony TVs, 720p content is well upscaled.

9.0 1080p Input

1080p upscaling is also great, with no softness.

4k content looks sharp without any problems.

This Sony reflects a lot of light. There is also glare around bright objects.
It's not able to get very bright. If your room gets lots of light and you plan on watching TV during the day, this isn't a good choice.

Just like with last year's Sony TVs, 1080p @ 120Hz produces little artifacts (lines), but this shouldn't be too bothersome while gaming.
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).

7.1 Mixed Usage
The main advantage of the Sony X830C is its viewing angle. The picture quality both in a bright and a dark environment is sub-par. It also has little blur, which is good.
