F2A-155H: The USB3.2 Gen 2 Type-C port is not compliant to DP1.4

Post by TVHD »

The official spec is found at: viewtopic.php?t=4956
Specification of the front USB-C port is:
"USB3.2 Gen2 Type-C x1 (DP/PD/DATA, supports DP1.4 video output, 4K@60Hz, maximum 10Gbps data transfer)"

DP1.4 official https://www.displayport.org/pr/vesa-pub ... rsion-1-4/ says:
"DP 1.4 further builds on the capabilities of the standard’s prior incarnations. The use of video transport compression enhances the ability to take advantage of the USB Type-C connector, enabling both high-definition video and SuperSpeed USB, while also facilitating High Dynamic Range (HDR) and 8K video across the DisplayPort or USB-C connector. Examples of increased display resolution with the new standard include 8Kp60Hz HDR deep color and 4Kp120Hz HDR"

I failed to operate a 4K HDR monitor using the front USB-C port:

Details:
  • Current versions of w11 pro (23H2 or 24H2)
  • Intel ARC driver 31.0.101.5448
  • Using the F2A's USB-C port I receive 4Kp60Hz, but switching to HDR (Windows setting) fails
  • Using the F2A's HDMI ports I receive 4Kp60Hz with HDR
  • Connecting the PD32M's USB-C input to USB-C output of a MiniPC of an "other brand" with an "AMD Ryzen™ 7 7735HS chipset" leads to fully functional 4Kp60Hz with HDR
May I ask if anyone is using the USB-C front port @ 4Kp60Hz with HDR?

Re: F2A-155H: Is the USB3.2 Gen 2 Type-C port really compliant to DP1.4?

Thank you for your reply.

Do you think it will be possible to fix this issue via a BIOS/EC-firmware update?
