cannot get 10-bit video on Ultra 9 185h

[Danrdz10103]

Trying to use an Asus NUC 14+ (Ultra 9, 185h, Intel Arc integrated;  80Gb RAM) as photo editing but I cannot get 10-bit video unless the monitor is in HDR (Monitor is an Innocn 32m2v). all my previous computers connected to  this monitor gave me 10-bit signal.

I dont see the option in  Intel Graphics Center. I am driver 32.0.101.6881. monitor connected to hub via DisplayPort and the hub connected to the Asus Nuc via TB4.

is this an Asus Nuc  limitation or the Arc implementation in the Ultra 9 185h does not support  10-bit in SDR?

Hi @Danrdz10103,

Thank you for posting here in our community. To effectively diagnose and address the issue you're experiencing, I kindly ask you to provide detailed responses to the following questions. This information will help us isolate the problem and determine the most appropriate course of action.  

• Please provide the SSU log report and share it here so I can review your system's configuration. 
• Does the Thunderbolt 4 hub support 10-bit color depth transmission, or could it be introducing limitations?
• Have you tried connecting the monitor directly to the Asus NUC without using the hub to see if the issue persists?
• Has the monitor's firmware been updated recently, and does it support 10-bit color depth in SDR mode? (please check with your monitor manufacturer)
• Have you made any software or hardware changes to the system recently? 
• Is this set-up is working fine before?
• What troubleshooting steps have you tried so far? 

For the meantime you can try checking these articles:

I look forward to your response and am committed to resolving your issue promptly.

apologies for the delay. I am still experimenting. I get 10bit video in one of my monitors but not in others. but feel free to close it and I can repost if necessary.

10-bit SDR over Thunderbolt didn't work for a long time, but since driver version 32.0.101.5768 there should be no more problems.

Please see this.

Manufacturer's specifications for the monitor (INNOCN 32M2V):

Using Coordinated Video Timing - Reduced Blanking (CVT-RB), this means:

4K @ 144 Hz RGB 8-bit = 90% HDMI FRL5 (40 Gbps)
4K @ 144 Hz RGB 10-bit = 112% HDMI FRL5

4K @ 144 Hz RGB 10-bit = 154% DisplayPort HBR3 ... OK with Display Stream Compression (DSC)

I don't know which dock you're using, but the monitor appears to have 40 Gbps HDMI ports and does not support DSC there.

If you connected the monitor via DisplayPort, changing the color depth should work. Otherwise, try reducing the refresh rate. 120 Hz should be sufficient for photo editing.
