[SOLVED] Display problems with new 6600XT

[Chanur]

Built a new PC with:
GPU: MSI Mechx2 RX 6600XT
Motherboard: ASUS ROG Strix B550-f
CPU: Ryzen 7 5800x
OS: Windows 10 Pro
RAM: G.skill DDR4-3600 8GB x2

Reusing an old tower, 750W PSU, and HDD which were working in the previous machine.

Everything works as expected with no video driver installed. Display looks normal.

As soon as I install the video driver, the display goes all weird. See photo. I've tried everything I can think of to troubleshoot. Updated Windows, BIOS, motherboard and chipset. Used the AMD driver uninstaller tool in Safe Mode . Tried several different versions of the video drivers from AMD and MSI, direct install and using the MSI's auto installer.

Pretty sure it's not a hardware problem. I swapped the card into an old machine running Windows 7 with the Windows 7 drivers and experienced the same issue with entirely different hardware. I thought it might be a problem with the card, and exchanged it.

Ignore the black bits in the top left corner of the monitor.

I don't know what else to try. Any ideas?
Thanks in advance!

Is this a newly built system reusing hdd with win7 install from another machine?

Could try installing Win10 from scratch to eliminate any os/ chipset or software conflicts.

Reusing os installs from different previous hardware can cause random issues. Couldn't say the distorted picture after loading drivers is the result of that but would try to eliminate that possibility.

Gpu driver installs power profiles etc, if it's not software related (soon see once windows is fresh reinstalled) then this falls back on the card, psu, or vga cable.

Clean install of Windows 10, not an upgrade from 7.
I went ahead and reformatted, reinstalled Win10, and all the drivers again this morning to be sure. Still having the same problem.

Pretty sure it's not the card, unless I got two in a row with the same problem.
HDMI cable and monitor work fine if I use them with a different machine.
Is this a problem that could be caused by a poor PSU?

What model psu and how old? Was same psu used testing card in another system?

Couldn't be software at this point. It's either the psu or card. If psu is low quality and old, might as well change it anyway. For Corsair rm750x, Superflower leadex iii 750w.

All I know is I have a monitor that is 144Hz refresh rate, and I tried to utilize this function with HDMI and it would only perform at 60hz max. I then discovered I had to have Displayport 1.3 or 1.4 to fully experience 144Hz for my new MSI 6600XT card, the same one you have. Some people advised me that the quality would not increase if I switched to Displayport from HDMI, and said it would only improve the refresh rate. I don't know about others, but it absolutely, significantly increased my image quality when I switched to a Displayport cable. However unlikely it is, try it. Maybe a million to one odds it helps you out.

I guess if Op's monitor is capable of going higher than 60Hz that installing driver is automatically setting to, the cable quality could be in question.

What monitor is it? When picture distorts like that try check, if you can see through that mess, what Hz is set to and try lower.

Thanks for all of the suggestions.

I swapped in a different monitor (both HDMI), now it works. Apparently newer HDMI is different from older HDMI? Who knows.

Radeon 6000 and Nvidia 3000 series have Hdmi 2.1 but is backwards compatible with older Hdmi versions and displays. What Hdmi version is your other monitor?

Glad it's sorted anyway.
