I have an Intel HD Graphics card. When I check the system, it says the graphics have been disabled because of a problem. When I use the Intel Checking Utility, it says everything is working properly. I do have graphics on the display, but the main screen is larger then the display. When I go in to change the resolution, it is locked on the current resolution. The only way to change it is by percentage. Even going to the largest percentage doesn't get everything on the screen. I have a Gateway DX4870 (P11 BIOS) and a Panasonic 50" Plasma Display. Any suggestions?
