Situation: Whenever the user opens Microsoft Edge, the small size is fine. However, if you Maximize, the windows shows only half.
Troubleshooting: 1. Reset display doesn’t fix the problem.
2. Right click on Microsoft Edge>App, reset or repair don’t fix the problem.
3. We also find some Windows applications such as Control Panel have the same problem.
4. We fix the problem by upgrade the display driver.
5. It happens again. I fixed it by upgrading the Monitor driver.
