Describe your issue:

 

Have to say that, i had the same problem the first time i upgraded from windows 7 (64bit) to windows 10 (64bit), about 1 year ago. I remember that i solved it after testing different solutions i tried from web searching and finally after disabling the card: "AMD Mobility Radeon HD 5000 series".

 

Unfortunately, after a recent windows updated i lost 1366x68 resolution. There is only option for 1024x768 or 800x600 resolution. As a result things on screen are stretched.

 

I downloaded and tried to install:

Catalyst Software Suite - 15.7.1 WHQL

Radeon Software Crimson Edition Beta - Crimson Edition 16.2.1 Beta

 

Unfortunately, installation is interrupted with blue screen error saying that there was a problem with "atikmdag.sys". After restarting, i updated display drivers through windows device manager. Now i can see the two display adapters:

- AMD Mobility Radeon HD 5000 series (with a yellow prompt)

- ATI Mobility Radeon HD 4200 series

but still there is no option for resolution above 1024x768.

 

If i click on "Radeon Settings" i get message: "No AMD graphics driver is installed, or the AMD drivers are not functioning properly. Please install the AMD driver appropriate for your AMD hardware".
