I have been running my two monitors, a 19" and 15" lcd, for years without problems in Vista. After installing Windows 7 recently, there is pretty bad lag only on the 15" monitor, as well as ghosting. If I drag any window around the monitor, it lags like a low fps game. If I move my mouse, it shows ghosting. If I turn off Aero and drag a window, it shows ghosting and no lag. I'm running the monitor at its native resolution and 60hz, just like in Vista.
The only change in my setup is that Windows 7 locks my 19" at 75hz and won't let me change it, no matter the settings I enable. It also doesn't let me update the driver, saying the default windows display driver is better. I had it at 60hz on Vista.
I'm sure this is a Windows issue, since it worked perfectly on Vista. This is a fresh install, so I have updated display and chipset drivers. Advise?
Edit: it also lags on the main screen, but it's only noticeable when scrolling the page while having a youtube video playing. Actually it's slightly noticeable when scrolling on any page. It's almost as if the GPU's 2d driver is broken or something. I have no problems in games - BF3 completely maxed out runs smooth.
