Video settings have gotten more complicated in the recent years. To be more precise, since HD TVs started to appear, there’s been more settings to configure.
The easiest part to configure is the resolution, as that’s pretty much done automatically and in the right way. The real confusion comes with another setting in the video, the RGB Range. Setting this part correctly is as important as the resolution, specially if you are going to take screenshots, record video, or stream. It’s even more important if you’re going to do any kind of graphic comparison.
