What happen?? i dont know, i need they help. Thanks.

Desktop in 1024 x 768 resolution, see the problem...

Use Catalyst 9.4 and select graphics card scaling in flat panel options.

I knew that catalyst 9.4 is not supported for Xprees Graphics Cards, you think that works?

If not maybe 9.2 has the option as well?

Ok, install Catalyst 9.4, go to notebook panel properties, go to the scaling options, default is Centered, i clic in Full Screen, but when i acept automatically back to Centered, why ?? I not to do
Waiting for other option

Maybe run CCC as admin?

the same, back to Centered TT___TT im craying

The problem is resize the resolution but Catalyst can't resize option and the resolution looks small someone can help me???
