I fairly recently completed building my HTPC and have everything working pretty well, but wanted to fine tune the picture on my display only to find that most of the adjustments are missing.
My display is a Pioneer PDP-5080HD 1366 x 768. Its manual states as a caution point that you need to "Make sure to select “PC” when a PC is connected to the HDMI input terminal." However, doing so eliminates the option of adjusting the picture to the same degree that you'd be able to with a non-PC source. The only adjustments I'm able to make are the standard brightness, contrast, color adjustments. Things like color temp, noise reduction, black level, Pure Cinema, and more of the advanced adjustments are not available.
Because I'm too curious for my own good, I decided to see if I would still get a picture if I set the HDMI input to Video instead of PC and it seemed to work. I didn't linger long because I didn't know what might happen, but my question is why does the manual state that the display must be set to PC? Would it be bad for the display? Can I make those adjustments on the PC if they're available and still get the same results as if I had made them on the display itself?
