As the "titel" says.... When I drag a window/finder around is has alot of lag on the second monitor.
I have one Mac screen - a 24" Cinema HD and the second one is a Asus VH242H.
It's the Asus monitor that lags.
Is it because it's just to heavy for the graphics card or ??? Both monitors are running in 1920x1080.
I think the graphicscard is a nVidia 8800GT 512mb.... If that means anything...?
I only use mac for/at work, so please don't spare the details.
The mac found the drivers on it's own.
I've been googling around but I can't seem to find any downloadable drivers for the Asus VH242H??
I tried a semi switch. I disconnected the Apple monitor and used the Asus as the only screen. The lagging seemed to disappear.
I will try to use the Asus as primary and the Apple as secondary later today and get back to you. (I simply forgot to do this when I did the semi switch )
