The age-old confusion about setting RGB levels right (aka. limited 16-235 or PC levels 0-255). I currently have an old LG PK250 Plasma, which is connected ONLY to the HTPC, and I am using these settings in my chain. Wondering whether this alright. LAV Video Decoder RGB Output Levels "Untouched, as Input" <--- not sure whether I should touch this setting at all . . madVR "Display is expecting PC levels (0-255)" . . The ATI Radeon 6450 I now set to "Full RGB" in the drivers. . . LG Plasma is set to using "PC" input label on HDMI, means it's taking 0-255 (Other input labels like "Blu Ray" expect limited 16-235) . . The display this way subjectively looks fine and I also used the blinking blacks bar test clips, so black levels are good. Yet, unlike as connected using a different input label, like Blu Ray etc., setting the PC input level results in VERY saturated colours, although I cannot say whether this is actually good or bad. It's just much more saturated than using Blu Ray input level. Also, when using this chain (HTPC connected as "PC"), I don't have all the advanced settings on the TV like tint, colours etc....means even if I were to think that the colours would be too saturated I could not reduce them. Any input whether these RGB level settings are alright? Thanks!
