Monitor randomly restarts

Problem: Monitor keeps shutting off and on seemingly at random. When it happens, it's off for anywhere between 1-3s, and it's usually multiple times in quick succession.

I built a new computer recently, and this has been a problem ever since with the new machine.

Hardware:
- Monitor: HP 2311x (connected via HDMI. I used this same monitor with my previous computer and had no issues.)
- GPU: Gigabyte Geforce GTX1660 Super
- Motherboard: ASRock B450M Pro4
- CPU: Ryzen 5 2600
- RAM: GSkill Aegis 8GB DDR4 3000MHz (2x)
- PSU: Corsair C430

Relevant Software:
- Did a fresh Windows 10 installation with the new hardware
- NVIDIA Game Ready Driver v451.67

Possibly related symptoms:
- Whenever the computer wakes up from sleep, the monitor needs manual intervention to work. The monitor powers on, but will tell me that no signal is detected. I have to switch the source every time to get it working. It is connected via HDMI, and the default source is set to HDMI. I need to switch it away from HDMI and back to make it work.
- Once in a while, the monitor will give me a message saying "Input Signal Out of Range. Change Settings to 1920x1080 - 60Hz", then after a while, shut off, turn itself back on, and the message disappears. This seems to be a message generated by the monitor, not the computer. As far as I can tell, my display settings are already set to 1920x1080 60Hz.
- Sometimes, when the monitor restarts, the output is horizontally shifted by up to 1cm to one side, leaving a black margin. Nothing is cut off from the other side. It just squished the output.
- The monitor's output "flickers" (random horizontal shifting) before it goes through the process of turning off and on.
- I haven't been able to notice this myself, but I've been told that it goes slightly blurry sometimes after restarting itself.
- If I have the monitor's OSD menu open when it restarts, the menu disappears as well, regardless of how long its been open.

- When I boot up, usually nothing will be displayed until after the OS starts loading. This means I can't reliably access the BIOS.

 

Things I've tried:

- I recently swapped out the RAM for Team T-FORCE DARK Z 32GB (2 x 16GB). The frequency of these restarts seem to have dropped significantly at first after making the swap, but it's slowly becoming more frequent again (just my perception. I'm not actually recording when it happens).

- Ran a GPU and CPU benchmark to see if it's related to load. Nothing happened during the benchmark tests.

 

I'd appreciate any help I can get on this.

bruh. if you have DVI, use the DVI instead of the HDMI.

there's a lot of issues with HDMI that a lot of people don't realize. but switching from HDMI to DVI will save you headaches.

I'm still on the lookout for a new monitor to buy. Until then, I don't have the option to try a new monitor. Do you know of anything else I can try in the meantime?

What makes DVI better than HDMI? I tried looking this up, and every source tells me that it's obsolete. My GPU doesn't even have a DVI output. Only HDMI and DP.
