Reduced blanking modes could be useful if it's a case of bandwidth. See: <a href="https://github.com/kevinlekiller/cvt_modeline_calculator_12">https://github.com/kevinlekiller/cvt_modeline_calculator_12</a> Something like this, using just xrandr (-b option indicating reduced blanking v2 mode): ./cvt12 5120 1440 45 -b Which yields: Modeline "5120x1440_45.00_rb2" 344.21 5120 5128 5160 5200 1440 1457 1465 1471 +hsync -vsync Then: xrandr --output DisplayPort-2 --newmode "5120x1440_45.00_rb2" 344.21 5120 5128 5160 5200 1440 1457 1465 1471 +hsync -vsync xrandr --output DisplayPort-2 --addmode DisplayPort-2 "5120x1440_45.00_rb2" xrandr --output DisplayPort-2 --mode "5120x1440_45.00_rb2"</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
