My monitor does not work with the ARC A770

  • I bought an A770 yesterday and it arrived for me today, when I connected it to my motherboard, it showed normal video and started the system. After 2 minutes the Intel program asked to update my video card driver and so that's what I did. After that, my monitor started to change colors, blue, green, yellow, purple and so on, but there was no image of the system anymore. My monitor is a Husky Hailstorm 165hz 31.5 inches. What do I do?

Hello PedroLucas


Thank you for posting on the Intel® ARC™ Graphics Communities. I know getting no display from your monitor can be a concerning problem.


This issue can be caused by a faulty cable or an incomplete/corrupted driver installation, we will need to try to reinstall the driver to check if that is causing the issue. What type of connection are you using between HDMI and DP? I would advise that you try both and check if the same happens as well as trying different cables.


Another option will be if you have integrated graphics to connect the video cable directly to your motherboard to check if you can get image that way.


If you are able to get to your desktop, reinstall the driver 31.0.101.4953 and if possible use Display Driver Uninstaller.

Thank you for the answer, but I can already solve my problem.
The problem was with the BIOS CSM option that was activated.
And as if that wasn't enough, my BIOS hadn't activated the UEFI boot option, which consequently didn't allow the card to start with the system correctly, causing my problem with the monitor.

Hello PedroLucas


Great to know you were able to resolve the issue after disabling CSM. It makes sense it worked since the UEFI boot is needed for our AR GPUs, you can check the requirements at the following link:
