I am running an ASrock e-350 motherboard with an onboard ATI 6310. I had this monitor hooked up to my HDMI port on my motherboard and was having problems with the sides getting cutoff. I have Windows 7 Ultimate and Powerstrip and it is set at 800x480. I have tried every refresh rate, but that did not have any effect (although I did no expect it to). Windows display properties also says 800x480. Derrick suggested on earlier to get a DVI adapter and run it through my DVI port. So I bought an adapter and tried it today. It looked exactly the same as through my HDMI port. I also saw he had posted to try the DVI input option on the video selection. That had no change either.
But then I notice that in the OSD it says that the monitor is displaying 760x570 resolution? So why would the resolution be different from my PC and Powerstrip settings, but different in the monitor display settings?
