As far as the picture goes on the EYGO, I have a different opinion than most. I like a fairly sharp picture. I don't like the scanline look. The EYGO is more sharp than a TV, less sharp than a regular computer monitor. For me, it is perfect. I ocassionally use my arcade PC for other uses, like web browsing and email while my girlfriend is on my other computer.
So the sharpness is just right... just fuzzy enough to make games look nice, but you can still read all the icons fairly easily in Win98.
The trick to setting these up is to change your monitor type in windows to generic VGA, 60hz. Then it won't even try to run it in anything above that. I get edge to edge video on every game I've tried, horizontal or vertical. It is great. I can't really comment on vector games though, because I'm more of a late 80's arcade fan.
Overall, I'd say it is a sweet monitor, especially for the price. Let me know if you have any other questions...
