It's a Westinghouse I got at Best Buy so it should be very easy to swap and return. I'm using the onboard video but I am going to try a Radeon 32MB AGP card and maybe even try the DVI connection after installing that if I can find a cable. Adjusting the birghtness didn't really do much either. I also have only two refresh rates come up on auto detect, 60 and 75. Tried both, no difference. I also searched for drivers but found nothing on the Westinghouse site.
It's a shame, the whole thing was $300 including tax and looks great, no dead pixels, good color and brightness. Just a very low buzzing. I'm betting it's the video adapter though, at least I hope.
