Really glad to hear that, jrose! I've experienced some technical difficulties which is why I haven't gotten around to plugging the monitor in yet. But this is fantastic news and I thank you for taking the plunge!

On kind of a side note Burger Time runs @ 99% while every other game runs @ 100% (pac-man, qbert, mk) . The monitor changes to the correct res (its a whole number res ). Its really weird but it doesn't effect anything just my sense of perfection ;-). I'll have to generate a log file on that game.

Calamity:

Check the log, it could be 99 point something... Anyway with this method you can only get an aproximation for the requested dotclock, sometimes a very good one but not always, some cards give you more precision (more variety of possible stable dotclock values) than others.

No offense but you way over my head at this point. You lost me at dotclock

Here is some of the log:
