ok so i have my computer an aspire m5100 with onboard hdmi hookup. i have uninstalled the onboard gfx card and installed my own. then just recently reinstalled the drivers for the integrated gfx cuz i want to run dual monitors. but it still refuses to show up on my display options. the integrated card is a ATI Radeon X1250 ive installed the drivers and nothing has shown up in display options to extend my monitor or make it my primary. is there any other reason i am not privy to that would cause the current integrated gfx to not show up on the display options?
