I have a problem with the resolution of my video card.
When I boot, then I have the full 2560x1440 resolution.
Once the PC is on Login Screen, the resolution drops to 1920x1080.
I've tried everything but nothing has helped yet.
Graphics card is a Sapphire Vapor-X R9 280X, Model: 11221-20-40G. It has 4 ports: DVI-D, DVI-S, HDMI and 1 x DisplayPort (no mini DP). Monitor is Acer K272HUL. However, only the DVI-D port is working under Yosemite. On Post and boot logo they're working all.
Here is a video of my problem: https://www.youtube.com/watch?v=B3DWuKJgXrA
The card worked OOB. BruceX takes 28 seconds and Luxmark is 2330. So I think the card is working. Only problem is the small resolution
Can anybody help me?
Many thanks!
