Radeon HD 5770 at G27Q20 monitor, how set 2560x1440 mode?
Hi!)
At my new 2K monitor i cant set 2560x1440 via hdmi
i am understand that limitation of hdmi specs at Radeon HD 5770
Video features
Multi-monitor: Up to 4 displays
Maximum digital resolution: 2560 x 1600
Maximum DP resolution: 2560 x 1600
Maximum DVI resolution: 2560 x 1600
Maximum HDMI resolution: 1920 x 1200
Maximum VGA resolution: 2048 x 1536
Anti-Aliasing technologies: 24 x MSAA
24 x SSAA
Adaptive AA
HDMI: Yes
HDMI version: 1.3https://www.gpuzoo.com/GPU-ATI/Radeon_HD_5770.html
But under Windows i am apply this patch and can set 2k mode with no issues
https://www.monitortests.com/forum/Thre … ck-Patcher
Is there similar bypass at Linux for set 2k resolution?
ps is it safe if i try use DVI > HDMI adapter for setup 2k resolution here via dvi?
