The Sony W850C is a good TV with excellent contrast and motion control. Unfortunately, it has too much motion blur and input lag to be a great gaming TV. For movies and general use though, it is a good choice.
At a wide viewing angle, the colors are not the same as in front. The blacks are not as good, either. The picture quality is better when you sit directly in-axis.
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.
We changed our test for motion blur. The score is now only based on the response time and overshoot of the pixel transitions. We test 12 different transitions. Click the response time number to see all the data and graphs. We retested all our 2015 reviews with this new methodology. We also capture how the backlight handles different luminosity settings. We will update our motion blur article in a few days to explain how all of this works, and how it translates into practical application.
The Sony W850C has more motion blur than average. The trail length for dark to bright transitions is a lot longer than bright to dark. At least it has very good backlight control. See here for details on how the 'Clearness' setting affects the clarity of movements via the backlight.
The input lag under game mode is 36.2ms, which isn't bad, but not great. The input lag with motion interpolation is really low at 50.5ms, which is definitely playable. So it is a good choice if you want your 30 fps console game look like a 120 fps game.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
This TV gets loud. Good frequency response at moderate levels, but at higher volumes the frequency response suffers and pumping may be present. Low-end cut off is not very good.
