Need help, my screen flickers when booting

[twocharacterslong]

Got my brand new  Intel ARC A750 today.

But unfortunately, when I installed the graphics card and booted, the screen kept switching between black screen and blurred screen. I had to reconnect my HDMI wire to my MOBO, and install the latest version of driver(4146). After doing so, I could boot my PC with HDMI directly connected to graphics card. However, whenever I open a game(MONSTER HUNTER ARISE) or start Furmark, the screen turns blue with code 'VIDEO_TDR_FAILURE'. People tell me that I should enter safe mode and use DDU to uninstall the drivers, but I just can't enter the mode, because of flickering when booting.

After I reinstalled Windows 11 and installed the latest driver, things got better. Smooth booting despite one or two flickerings. I can play games normally. The system can survive Furmark without crashing. But still, I can't start my PC in safe mode. Neither can I enter BIOS. Tried many times, the screen just flickers.

Is this a software problem or a hardware problem? Things got better after I reinstalled the system, so I'm not sure about this. Should I ask for a replacement?

I don't see anything like this online. Can anyone help me?

Update: It worked for me to change from HDMI to DP. No flickering any more. Not a single error occurred so far. But still I’m very confused which one I should blame it on, my monitor, a750 or the wire? I’ve read some posts about not working with DP but good with HDMI, it seems exactly the opposite to my problem. Need some advice.

Hello twocharacterslong

Thank you for posting on the Intel® ARC™ Graphics Communities. I am sorry to hear that you are experiencing flickering display issues when using your Intel® Arc™ A750 Graphics.

I understand that the system works fine when using a DP port, please let's try the following:

1.-Install the latest driver version 30.0.101.4146 using Display Driver Uninstaller.

2.-If possible, please try a different monitor or different HDMI cables.

If the issue still persists, please let us know the following:

• Is Resizable BAR enabled on your system?
• Create a log file with the Intel® System Support Utility and attach it.
