fr33jack, when i had my 280x, 2560X1440 was the maximum it could do. Whether 15.7 drivers have changed that i cant say for sure. On another note, this doesn't work on my 290x. After rebooting 3200x1200 is still the maximum it shows. Im gonna try adding 2240x1260 and 2880x1620. Hopefully shouldn't be any issues as its below 3200 resolution. Will report back.
