What is PC Mode?

PC mode is a special mode on some TVs which turns off many of it's processing 'features'. On my LG plasma for example, if I name the HDMI input as 'PC', almost all of the 'fluff' like dynamic contrast etc is greyed out.
Unless you put your TV into PC mode, it is almost certainly converting an RGB signal into YCbCr (and probably 4:2:2 or maybe worse, 4:2:0) to do all it's processing, and then converting again to RGB for final display.
In PC mode, you may or may not avoid this conversion process - to use my TV as an example again, in PC mode, all of the stuff I don't use anyway is greyed out, leaving only the basic controls and the CMS, but I have no idea whether it's bypassing this RGB-YCbCr-RGB process, all I know for sure is in PC mode it passes the 4:4:4 test (if not in PC mode, it shows 4:2:2, a clear indicator that it's converting an RGB signal into YCbCr).
