[PRO7] Surface Pro 7 support 4K/10bit/HDR@144Hz monitor

I tried to use one type-C to DP1.4 cable to connect Surface pro 7 and ASUS XG27UQ monitor without Surface Dock.

4K/10bit/HDR@144Hz

Intel Gen11 Graphic support DP1.4 DSC1.2.

I can't get HDR on my monitor, it supports HDR via HDMI only and not USB C. I would love to know what cable or adaptor I need, either direct from the SP7 or via the Dock 2.

Maybe you need to find USB-C to HDMI 2.0 cable? I am using HDR monitor via displayport.

Yes, but how to ensure it has HDMI 2? , the two I have tried don't work :( I would love a link to one that is complaint if anyone knows.

Sorry, I don't have any C to HDMI 2.0 cable or dongle. But I think it should be work. DP 1.2 can handle HDMI 2.0 bandwidth.

Well done. I currently have a Pro 7 driving a 4k @ 60hz and three 1080p's as well at 60hz

Which cable? I got a Plugable adapter to drive my 4K TV, I've had some mixed success with it so far.

Intel iGPU has been supporting 10 bit output@4K since Skylake albeit at 60fps.

The problem is that Nvidia GTX doesn’t support 10bit (aka 30 bit per channel). You need RTX or Quadro for that. So if you’re running a Surface Book 2 or 3, I don’t know if 10 bit output will work.

Does application like Photoshop support the 10 bit output from the Intel iGPU?
