Anyone know why only an older monitor will work on my hackintosh Monterey?

Its an HP Elitedesk 800 g1 running Monterey. Obviously the vga wont work but i used the dv out with an adapter to hdmi. It wont work on my new monitor, or my hdmi tv, but i does work with a wire i have that is hdmi on one end and vga on the other in an old dell square monitor, the one that I use for working on projects on my bench. When I try to transfer it to my bedroom or the den. The video doesn’t work at all, not even letting the monitor know to turn on no signal whatsoever. But I plug it back in on the bench to monitor from 2005 and it works fine. Anybody have any idea why this is happening is it because I was using that monitor when I installed it? if so, do I have to start over again to remedy this problem I really don’t wanna use it on such a tiny square monitor. Any help would be greatly appreciated. You guys have already helped me so much I can’t believe I even got this to work!
