I have the above fitted in my HP PC, I've just updated to Win 10 from 8.1.
I downloaded Catalyst 15.7.1 for Win 10 (64 bit) and installed it. After this my screen resolution dropped from 1920 x 1080. The maximum I can get now 1024 x 768.
HP tell me to install AMD Graphics Display Add-on Unified Win10 (64-bit) 3CT5. I've downloaded this but it fails to install.
Reading the information for Catalyst 15.7.1 it doesn't list the HD7450, have I installerd the wrong one?
Any suggestions appreciated.
