I was wondering if there were any hardware buffs that could help me out.

I have a Viewsonic P95f Aperture Grille CRT. I've had this for about a few years now running with no probs. Tonight for some reason, the left side of the screen started to cave inwards. I literally watched it happen.

It's been running on 85Hz with a screen resolution of 1600 x 1200.Changing the refresh rate to 75Hz solves the problem except I notice horizontal squishing of the image close to both edges.

Changing resolution also solves the problem. But having the combination of a refresh rate at 85Hz and resolution of 1600x1200 results in the edges being caved in (after switching refresh rate settings or resolution settings now results in both sides being caved in).

I've also used the monitor control panel to adjust pincushioning but that does not help.

Does anyone have any insight as to why this is happening? I'd say replacing the monitor isn't an option I want to investigate as the current crop of LCD monitors are not up to standards I'm used to (including high-end enterprise monitors).

I don't know if this is circumstantial or not, but yesterday, my left speaker stopped working (it's placed to the very left of the monitor). Would a speaker on the fritz cause interference with a monitor?
