I recently upgraded from a Sapphire HD5870 to a Club 3D R9 290. The problem I am having occurs with both cards, I cannot seem to upgrade past
Catalyst 14.4 from June 2014. With either card inserted, after installing any later driver my monitor will display "Invalid Mode". I use a Westinghouse
LVM-37w3 1080p@60hz and a DVI connection. I've always used the DDU driver cleaner when installing drivers. I've tried running 640x480 mode after
hitting f8 after post but same thing happens, so i'm thinking its the refresh rate?
