Some video issues

[BenDalton]

WG k4600 Monitor
Trident Blade t64

First issue: The image appears to be either misshapen (pincussion effect) or there is just a weird discolored line on the left hand side of the monitor.

Second issue: When switching between FE and games, the screen 'wiggles', loses sync, and then regains sync. This is a little annoying, would a cap kit fix this kind of behavior?

Third issue: This is a software issue, but I installed easymamecab and my neogeo games show up rotated 90degrees and are having vertical hold issues. How do I make sure these are being displayed right w/ my monitor and setup??

Thanks in advance for any advice you all have!

If the monitor has not been recapped then that's the first thing to do.
