It seems that Windows 10 has excluded or shut out my Geforce GT520 graphics card. My screen resolution is not what I would like it to be. There are only 4 settings that I can choose from now which are: 800x600, 1024x768, 1280x1024 & 1600x1200. I cannot remember, but I'm sure there was one more with my graphics card. Can anybody please advise?
