I'm having some problems with my newly bought SyncMaster B2230H.
When I try to set it to its native resolution - 1920x1080 - I get a "zoomed in" effect. Part of the screen is missing, but can be reached by dragging the mouse along the edges. This is happening both on the desktop as well as in applications.
I've read suggestions that it might be a problem with the videocard drivers, but removing, reinstalling or updating them hasn't been a solution for me.
I'm on Windows XP running a Radeon HD 4870 videocard with the latest drivers (Version 10.11). I don't know if it's relevant, but the monitor is connected with the video card by VGA through a VGA-to-DVI adapter, as a DVI cable wasn't included with the monitor.
Thanks in advance for any assistance you might be able to offer me.
