I have a Mitsubishi Diamond Pro 930 SB...I use reforce to lock refresh rates for video games since XP wants to use 60 hz. Anyway, I run a desktop resolution of 1600 x 1200 and my refresh rates are: FH 106.4 and FV 85.2 and next to each one it says POS. which i assume means positive. When I go into this particular game I play at a res of 800 x 600...FV goes to the max my monitor can do at that res which is ~160 but the FH I believe stays the same as when I'm on my desktop but this time it says NEG. next to it. I have no idea what that means because my previous monitor never said that...I looked through the manual and couldn't find anything about it...anyone know off hand? TIA
