Hi guys.
I own this P2715Q just several days. At beginning I was so happy with the "1.07 billion colors" as its tech specs description when I just got it. But now, I really doubt this description after my investigation.
Here is the thing. I find on my PC under AMD catalyst control center - My Digital Flat Panel - Properties(Digital Flat Panel) - Color Depth only shows me two options "6 bpc" and "8 bpc" after I properly connect this monitor to R9 290 through miniDP cable. Since tech spec mentions P2715Q support 1.07 billion colors which is 10 bits color depth (I know this P2715Q uses a 8Bit + A-FRC to get a 10 bits color depth.). Thus, "10 bpc" should be expected under the AMD CCC color depth setting.
Furthermore, I pull out the EDID information through a AMD EDID UTILITY. Base on EDID 1.4 version data form, the data on location "14h" is the video input definition. If the monitor really supports 10 bits color depth, the data under "14h" should be "1 0 1 1" for 7th, 6th, 5th and 4th bit. However, my monitor EDID data under location "14h" is "A5" which is "1 0 1 0 0 1 0 1". It shows "1 0 1 0" for 7th, 6th, 5th and 4th bit. That means this monitor only support 8 bits per primary color based on interpretation of "VESA ENHANCED EXTENDED DISPLAY IDENTIFICATION DATA STANDARD".
So I want to know whether this is a single case or it happens on all the p2715q monitors. Can any P2715Q user look at your AMD CCC setting if you are using AMD graphic card or just pull out the EDID information?
