It didn't seem to do much, but I'm being a bit impatient so I'll do some proper testing tomorrow.

You probably know what you're talking about, so I'll assume it is indeed 'doming'. Every example of impurity caused by magnets I've seen online seems to have a much more apparent and catastrophic result than the subtle but noticeable enough to be frustrating issue I'm having. I'm beginning to get used to it though, I think(???) :P

On another note, it is connected to an HDMI to VGA connector, but common sense would tell even me that this has nothing to do with it, could be wrong though?

Thanks for bearing with a newbie like myself, I'm quite new to the world of CRTs!
