Just did a clean Windows 10 install and using a Viewsonic monitor that won't get native 1920 X 1080 resolution. I know monitor is OK as it does on other computers. Machine has AMD Athlon II X2 250 processor, no separate video card. Other machine monitor attached to is a Windows 8.1 with intel chips and that displays the native resolution. I believe there are no more updates coming from Windows Update so I'm hoping I can get what's needed from AMD.
