Well, I do mention that as a PC monitor it's only mediocre, but that it excels as an arcade monitor. The PC display is worse than a real PC monitor, but better than a "TV out" solution.
The convergence problem on my unit is noticeable, especially with PC display modes. White lines near the top middle of the screen "break apart" into two separate colored lines, as does text.
You don't notice it in an arcade game as much, although if there's white text at the top (a score, perhaps) you do notice the color ghosting.
Monitors have a lot of variation in them, and I've seen worse convergence in some cheaper PC monitors, especially those that had no convergence controls, ironically.
The more expensive monitors, the ones that had convergence adjustments, didn't actually need them.
I've also had monitors that "fixed" their convergence problems miraculously, and I suspect that it may be related to the whole degaussing/color purity issue. I won't know for certain until I get the monitor into it's final home and give it a good degaussing.
I'm being nit-picky, I know, but in the end the display is one of the most-used parts of a computer system. It helps to go into a big purchase like the D9200 knowing what level of display quality to expect.
I'm not returning it, that's for sure.
