What would cause a WORKING Radeon RX570 4G/Ryzen 5 5600x to suddenly black screen in a Windows 11 PC as soon as the display is increased to anything above 1024x768 (i.e., 1280x720 black screens!)? It runs fine at 1024x768!

Fresh Windows 11 install, with only Windows and AMD drivers (amd-software-adrenalin-edition-24.5.1-minimalsetup-240514_web) installed

AMD Ryzen 5 5600X
Radeon RX 570 4G
Two 8 gig 3200 DIMMs (16 gig total) running at 2100 MHz (also tried 3200 MHz, but no difference)

Device Manager: "Radeon RX 570 Series" display adaptor

750 watt Corsair PS
Gigabyte B450M DS3H board with latest BIOS (2019 server has the same board and ps!)

Windows 11 Pro installed on a 1 gig SSD

For the past 3 years, we've had this Radeon RX570 4G & Ryzen 5 5600x running in our 2019 Server (32 gig RAM with Gigabyte B450M DS3H board) at 1920x1200 without any issues. We upgraded the server's CPU/GPU, so I swapped the server's CPU/GPU into our Windows 11 PC (16 gig RAM with the same Gigabyte B450M DS3H board and Corsair ps), replacing its original Ryzen 5600G, which had been running at the same display setting as the server (1920x1200) without any issues.

However, as soon as I try to increase the display on the 11 PC to anything above 1024x768, the screen goes black and the monitor's "Entering Power Saver Mode" start-up message pops-on for a half-a-second randomly every 20~30 seconds or so & it'll just sit there for hours like that.

I've tried wiping the SSD and reinstalling Windows 11, but no change. Thinking it might be some type of incompatibility with Windows 11, I tried installing server 2019, but no change. I've tried both the default and optimal BIOS settings, but no help there either.

I'm an IT guy with many years experience and I've never had an issue like this before. Any ideas here?

The most recent supported Adrenalin version for RX 570 is 24.3.1 - did you have the 24.5.1 installed with the 5600G?

Try removing 24.5.1 and install the older 24.3.1

Thanks for the reply!
A couple things for clarity:

1) The PC with the black screen issue (Windows 11 PC) currently has the 5600X (with the RX570), not the 5600G. I swapped the G CPU for the X CPU (on the 11 PC) when I installed the RX570 GPU a few days ago.

2) I only installed the current/latest AMD driver after trying all of these earlier drivers that we'd burned onto a DVD when the CPUs/GPUs were originally installed. I can't recall which, but one of these drivers was used for the 2019 Server (running the 5600X and RX570—which are now in the 11 PC) and the other was used on the 11 PC with the 5600G:

original rx570 drivers

I only tried 3 of these old drivers, but they all indicated that they were not compatible with the OS, so I didn't try the 4th.

Again, both PCs—the 2019 Server and Windows 11—have the exact same Gigabyte motherboard, Corsair power ATX supply and DIMMs (though the Server's got 32Gigs and the 11's got 16Gigs). Really, only the cases  and the OSs are different. Since the black screen issue occurred the first time I powered-up the 11 PC, I figured either the GPU somehow got damaged during the 3 foot move from the server to the 11 PC when I transferred it over (highly unlikely—I've been building/repairing PCs since the early '90s) or it was incompatible with Windows 11......that's why I wiped 11 and did a plain Server 2019 install on that PC. Still black screened! So I pulled the CPU/GPU and reinstalled them into the server. They worked perfectly. So it's got to be something with the 11 PC, but I can't figure out what?? That's why this is so confusing. Grrrr..

I forgot to include this in my original post, but here's the [Display] output from DXDiag (I can post the full contents of the report in a .txt file if requested)..

Grabbing at the proverbial straw here, but ..

Since 1024x768 is the limit of VGA, I'm wondering if the card's being limited to VGA output or something like that.

Is there a setting somewhere within either Windows or the AMD drivers that sets or limits video output to VGA??

Solved!

Defective HDMI-to-VGA cable converter.

Because our Dell monitor doesn't have an HDMI input, we've installed HDMI-to-VGA cable converters to all the video cables, which works fine....at least when the cable converter's working fine. Apparently, the one on the 11 PC was defective. I figured the problem had to be hardware-related, so I started swapping components back and forth between the server and the 11 PC and when I swapped the cable converter, the server suddenly black screened and the 11 PC displayed 1920x1200! Kind of a hint...

Anyroads, for future reference: If you're using one of these HDMI-to-VGA cable converters, check that first!

No idea why it wasn't disclosed from the start that display adapters were in play, when the issue was obviously display related. Congrats on solving your self-induced problem.

FYI - VGA is not limited to 1024x768. Both VGA and DVI support up to 1600x1200 (4:3) or 1920x1080 (16:9)
