As a summary I was using my computer with two monitors for a long time, 5+ years. Two days ago I turned on my computer and both monitors began displaying the same thing, not as 1 split desktop as they had been, and the resolution was down to 1024 x 768. I can increase the resolution to 1080x1024, but not any higher and both monitors will only mirror one another. I check dxdiag and it says that my graphics device is "Microsoft Basic Display Driver." I went to check the device manager to try messing with the drivers. Here it lists the display adapter as my ATI Radeon HD 4800 (old I know). Since then I have tried everything I could think of to try to fix it and to no avail. I figure a new graphics card would probably fix the problem, but I'd rather not have to spend the money. Any advice would be appreciated.
Running Windows 10 64bit. Pictures attached of my dxdiag and device manager.
