I have a Dell Latitude D520 with Intel 945GM chipset on board and WinXP. I started working with an external monitor a while ago (Gateway EV910). Initially everything seemed to work ok, and I was able to set the monitor to use its max resolution (I think it was 1200*1600). But then I stared getting blue screens whenever I connected the monitor. So I downloaded from Dell the newest driver for the Intel chipset. This stabilized the system. But now the monitor won't go beyond 1024*768 and it won't do more the 60Hz refresh rate (very annoying).
I searched online for the monitor driver but couldn't find anything.
