I have a fx 4300 and no vga installed, i installed Windows 10 x64 and the display resollution can't get any higher than 1152 x 864. Is there any way to solve this? Because when i was using windows 7, the resolution were at 1600 x 900... And sorry for my english, it isn't my native language.
How about posting your Sys spec. That will help some one to help you out.
It sound like you are using MS drivers for your GPU (stander VGA driver), you need to down load the drivers for your Graphic card/ on board graphics, which ever the case may be.. Your CPU doesn't have any thing to do with screen res, your GPU does.
