Graphics corrupted on Neo Geo MVS...I think

Just got a new 2 slot cabinet. Having some monitor issues (dim, whole picture is a bit off horizontally), but I think the graphics look corrupted on my two cartridges although metal slug certainly seems more normal. I think. But both games having issues makes me think it's not the cartridges but the motherboard. Is that right?
The monitor is funky to the point that I almost couldn't tell if it was just the monitor but I think it's more than that. Some of the dials on the adjustment board connected to the monitor (an NT-2500) make adjustments and some seem to do nothing.

I took the board out and cleaned it up for what that's worth.

Very short video of metal slug--I really can't tell if it's messed up or if it's the monitor making it hard to see well.

No, that is all indicative of a bad monitor. If you turn down the gains on the colors those smears will go away (but it will be even dimmer).
