My wide screen laptop suddenly became 1024x768

This is the Microsoft driver that's giving trouble.

If you can use "roll back" option, do that.

If not, try use AMDCleanupUtility, reboot, wait for Windows to automatically download latest drivers (took about 10-15 minutes for me), then use Rollback options on those drivers in Driver Manager.

Same thing happened yesterday and it worked for me, although I don't have notebook but it was desktop with ATI/AMD Radeon HD4670, WIN 10. Now I have 8.970.100.9001 driver version, which is mentioned in GPU-624 Article Number (works from HD 2000 up to 4000 desktop and mobility series) at AMD website.

The same thing just happened to me. Here's what I did to fix it. Open Device Manager (as administrator), find the driver under Display adapters and tap Properties. On the Driver tab, tap Roll Back Driver. There is a way to prevent a Windows Update from changing the drivers but my Windows 10 version does not support it.

Wish I had looked through this better today before ripping all my cables out of the wall.

To roll back to a previous version of a driver

• Open Device Manager.
• Right-click the device for which you want to roll back to the previous version of the driver, and then click Properties.
• Click the Drivers tab.
• Click Roll Back Driver.
• In the Driver Package rollback dialog box, click Yes.
• this has never faild
