Hi everybody,
I'm trying to setup a 27" screen on Fedora 23 (intel driver installer 1.4.0 Q4 2015) attached to an HDMI (ultrabook ASUS UX31A). I know it needs "reduced blank" and a timing of max 50Hz in order to work - with the max Bandwith on HDMI (at least that way it works on Windows using the same setup and "CustomResolution.exe") - But it dies not work so let me describe what I did so far:
1st guess)
"cvt -r 2560 1440 50" >> ERROR: Multiple of 60Hz refresh rate required for reduced blanking.
2nd guess)
Also The same seems to be true for "gtf"
"gtf 2560 1440 50" # 2560x1440 @ 50.00 Hz (GTF) hsync: 74.10 kHz; pclk: 256.09 MHz Modeline "2560x1440_50.00" 256.09 2560 2728 3008 3456 1440 1441 1444 1482 -HSync +Vsync
>>>> Does not work
3rd guess)
A Modeline that I've found on the internet :
xrandr --newmode "2560x1440_50.00_rb" 200.25 2560 2608 2640 2720 1440 1443 1448 1474 +HSync -Vsync xrandr --addmode HDMI1 "2560x1440_50.00_rb" xrandr --output HDMI1 --mode "2560x1440_50.00_rb"
>>>> Does not work either => Results in:
Apr 23 15:30:39 schleppi-ultra.balg.lan /usr/libexec/gdm-x-session[2986]: (II) intel(0): resizing framebuffer to 5504x1440 Apr 23 15:30:39 schleppi-ultra.balg.lan /usr/libexec/gdm-x-session[2986]: (II) intel(0): switch to mode 2560x1440@49.9 on HDMI1 using pipe 0, position (0, 0), rotation normal, reflection n Apr 23 15:30:51 schleppi-ultra.balg.lan /usr/libexec/gdm-x-session[2986]: (II) intel(0): resizing framebuffer to 5504x1180 Apr 23 15:30:51 schleppi-ultra.balg.lan /usr/libexec/gdm-x-session[2986]: (II) intel(0): switch to mode 2048x1152@60.0 on HDMI1 using pipe 0, position (0, 0), rotation normal, reflection n Apr 23 15:30:51 schleppi-ultra.balg.lan kernel: [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe B Apr 23 15:30:52 schleppi-ultra.balg.lan kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun
Last try)
Read the modeline from "PowerStrip" from a running windows on the same machine that actually runs the wanted resolution:
xrandr --newmode "2560x1440" 200.002 2560 2608 2640 2720 1440 1443 1448 1474 -hsync -vsync
But this only switches to a black screen and causes the "pipe_off wait timed out" message in dmesg below...
I've found the following two graphics related problems in the logs (dmesg) which might help as well:

I've tried this using Wayland and Classic X as well ...
Any hints on how to get this thing up and running with this stuff - attached Display is a DELL U2715H ?? -
Any more helpful information needed ?
