Question My new display output is wavy on my MSI OPTIX G241 and a very old computer ?

I was building a new pc. Couldn't get a gpu so connected the new Dispatch to my old computer.
Can't even set windows to 1080p. Setting windows 7 to 1080p results in non fullscreen output. And the display has waves forming. Connected my cable to my monitor and it didn't have the issue then. Only when I connect it to my PC. Is this a graphics card issue? I'm running an intel pentium e5800.

What is the make and model of the graphics card in that old PC?
Are you sure that it supports the combination of resolution and refresh rate?
