/vr/ - Retro Games

So I started playing N64 on my video monitor and I've been noticing this line of light at the top. Some games it's there, some games it's not, and sometimes it'll just be hidden enough that you can't outright see it. I thought it was something wrong with my CRT, but other systems seem to display just fine and 240p test suite doesn't show anything wrong with the alignment either. It doesn't show up when I have the monitor on by itself either, it's like specifically the N64.
Anybody know what's going on? I'm using a mechanical switchbox and an everdrive 64 right now, but far as I could tell the problem persists even when I eliminate those.
