intel arc a750 no display with display port

[mikotouwa]

I can't use the display port on the A750, it only displays red, green, blue then black screen again.

I have rebooted, replaced the dp cable with another one, changed the driver version but still

HDMI works fine but only 60hz can't be changed even though my monitor can do 120hz on an HDMI 2.0 cable, I want to use DP because it can only be used at 60hz and I use the DP with my old card.

Operating System: Windows 10
Processor: ryzen 5 3500x
MOBO: asrock B550M pro se
MEMORY: 32 GB
GFX: Intel ARC A750 (Driver: 32.0.101.5972)
HKC monitor g271f 144hz (DP 1.2)

Hi mikotouwa,

Thank you for posting in the community, To further investigate this please answer the following questions below:

1. I see that you have an HP monitor, does it also connects to your Intel Arc?
2. Also, you have mentioned that you have old card, when you change to Intel Arc graphics did you use DDu to perform clean installation?
3. Have you tried the HKC monitor on different system?
4. Have you tried using different DP ports on the graphics card?

I am looking forward hearing from you soon.
