@Stat_headcrabbed The SD/HD reference here refers to the BT.601 and BT.709 color spaces. BT.601 was designed for CRT and is considered the standard for SD (images that are 720 x 576 or less). BT.709 on the other hand was designed for LCD. But both of these color standards use the limited range Y'CrCb values and thus need to be expanded to full range RGB (as the rest of the graphics stack writing to an RGB texture will use full range).

The color depth setting from the graphics card control panel will then determine what is sent to the monitor. So this change won't impact that. It's just making sure the value for black from a video matches the value of black from, for example, a shader.
