Hi everyone

so i have a problem theoretically with the new monitor that i bought last week and it's that it says that it'll support 10 bit color depth in 4096x2160 at 60 Hz but the problem is that neither Displayport 1.2 or HDMI 1.4 is not capable of delivering 10Bit HDR range color , so the question is how this monitor can deliver something that it doesn't have enough bandwidth on it's ports to support?

(what i meant by theoretically is that i haven't test it yet because i'm waiting for my new CPU and currently i don't have a compatible system to test it with)

4096x2160 at 60Hz with 30-bit color depth is ~16.7Gb/s, which is under the 17.3Gb/s limit of Displayport 1.2. As for it not being able to do this with HDR, that's irrelevant because it's not an HDR monitor. The HDMI is only good to 24Hz so you can consider that input good only for movies.

As for 10-bit per color, many cards can do it under DirectX but only Quadro and Firepro cards have the 10 bit per color output buffers required by Photoshop for 10-bit.

thanks for the reply , but this monitor has a DCI-P3 coverage of 97 percent so that practically is HDR in case of the WCG so isn't there any problem regarding that?

and other question is : is i5-7500 able to handle such resolution over Asus Z270-A onboard displayport?

WCG is the ability to reproduce more colors than the typical REC.709. HDR includes the ability to display much brighter gamma than typical displays and the multiple competing standards differ in what additional information is sent.

GT2 in HD 630 should drive 4096x2160 at 60Hz with 32-bit color just fine over Displayport 1.2. While outputting 10-bit per channel color isn't supported except in DirectX, it can encode and decode 10-bit videos with hardware acceleration--just not at that resolution (3840x2160 is fine).
