Purity issues on a HP MX70 Monitor

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!

This could not cause it. A problem with the connector would not be subtle.

Is too large the colored areas, or is only near the contours/lines? (to be sure)
Some not so focused CRT can exacerbate convergence issues. Especially on high resolutions, one can not expect a "LCD" pixel resolution, although some hi-end monitors are very good with this.
