20M4 is a high-end PVM from the late 90s. Has all the connections you need, high TVL, games look fantastic. Test it out with patterns or games you know well how they should look. I say go for it if the picture looks relatively problem-free* and the price is reasonable ($100~).
*it's an aging set but should be bright, colorful, jitter-free, reasonably sharp with a little softness here and there, have only minor mis-convergence that doesn't distracting during gameplay, no permanent discoloration or weird splotches after degaussing.
This is the picture on mine:
It has some of the minor issues outlined above but good overall. The biggest one that you can't see because I put in extra overscan is a "squashed" upper right corner that can't be fixed with geometry controls (needs well-placed magnetic strips on the inside).
