My TV/Monitor keeps randomly disconnecting, and ONLY while playing Metaphor

I'm not sure why this is happening, but when I play Metaphor on my PC, my monitor keeps disconnecting. Sometimes it happens after an hour, sometimes after 30 minutes, sometimes after 5 minutes. When it happens, the only way to get fix it is to restart my PC. And this ONLY seems to happen with Metaphor (and the demo), for some reason. My other steam games don't have, and have never had this problem.

I heard that changing the framerate cap can fix this, but it hasn't. My TV only had 60hz refresh rate, and it was happening while the framerate was uncapped, and also with it set to 60fps. I've also tried having the resolution set to 3840x2160 and 4096x2160, starting the game through both Special K and through Steam, using a different HDMI cable, and cleaning out my PC's internals. Nothing has worked.

Has anyone else run into this problem? How do I fix it?

Not in this game, but I've had it happen before. Sounds like, rather than the game, your GPU is the issue, or it's not receiving enough power.

First thing to try is updating your graphics driver. If you're already on the latest driver, you could try using DDU (Display Driver Uninstaller) and following the steps carefully to fully remove and reinstall the drivers, but it's probably unnecessary.

If it's not the drivers, it's probably the power supply. Demanding (or poorly optimized/freshly released) games need more power than others. If the GPU is diverting power to finish its processes, then it's not receiving enough. This only applies if the monitor is connected through the GPU, of course.

If it's not connected through the GPU, but rather the Motherboard, it may be a resizeable BAR issue. In that case you'll need to read on your board's documentation to see if it can be adjusted in the BIOS.
