Cheers mate, but was asking does your actual monitor report its Vertical Hz at... from the resolution charts I've seen (in regard to your listed monitor and in hoping to help you a bit), it would be more like 59.9xxHz at 1920x1080.
this ain't gonna sync at the 60hz the Op Sys/ VGA says.
what happens is; a bit of jittery (which some might call stutter... ). It also introduces judder (which some might also call stutter), when movement on screen, usually terrain, I right/ left (not up/ down) and a slight pause or two when it all tries catch up to each other and perhaps a bit of tearing on occassion
Now... you've got a motherboard close to its end of life, a slow platter drive, and a monitor ill suited for gaming monitor, it seems.
have you thought of doing yourself a favour and perhaps, upgrading the hardware?
