Dual monitor problem

[oscareat8]

I recently installed windows 7 , one of my monitors said " Input not support ", but my other monitor was working. I set the resolution to 1280 * 720 it worked. I want to set the resolution to the max. I installed drivers, nothing worked. I open device manger, and clicked on display adapter. it said Standard VGA Graphics Adapter. on my other windows 8.1 , it said Radeon™ HD 8670D graphics. Please help me.

what are your specs? make sure you get the latest driver for that graphics card.

Do you have the latest Radeon HD/CCC drivers? Also make sure the connection is secure between the two monitors and your computer.
