Bought new HP Pavillion computer, Windows 7. Only has DVI capability so I go out and buy new monitor: Acer s201hl. Unfortunately Windows 7 doesn't recognize it. So it displays - but everything is super big - but it won't let me adjust resolution. I attach my friend's Samsung - no problem, it is perfect. Reattach the Acer - still same problem. I am sure there is something simple I am missing? I do have a VGA cable - I guess I can get an adapter - but why must i lose the DVI capability? Is this Acer's problem or Windows 7 problem? Who can help?
