I am looking at the tiniest text I have ever looked at
Hooray
I got it working, hoooooooray.
Like this:
https://www.x.org/wiki/FAQVideoModes/#o ... powerstrip
download PowerStrip (but not from
entech because their server disconnects again and again and again ... but from some mirror, find by google)
Then windows, install PowerStrip, reboot(!), follow those instructions ... and end up with something like this, in your clipboard
Code: Select all
PowerStrip timing parameters:
3840x2400=3840,8,104,144,2400,1,2,21,148931,1
Generic timing details for 3840x2400:
HFP=8 HSW=104 HBP=144 kHz=36 VFP=1 VSW=2 VBP=21 Hz=15
VESA detailed timing:
PClk=148931.00 H.Active=3840 H.Blank=256 H.Offset=-8 HSW=104 V.Active=2400 V.Blank=24 V.Offset=1 VSW=2
Linux modeline parameters:
"3840x2400" 148.931 3840 3848 3952 4096 2400 2401 2403 2424 +hsync +vsync
Then reboot into linux, and:
xrandr --newmode "3840x2400" 148.931 3840 3848 3952 4096 2400 2401 2403 2424 +hsync +vsync
xrandr --addmode HDMI-1 "3840x2400"
xrandr --output HDMI-1 --mode "3840x2400"
And ooooops, suddenly I have 9.2 million pixels in front of me, a whopping 4.44 K screen. Wow.
The display OSD says:
Code: Select all
3840 x 2400 @ 15 Hz
H.Frequency: 36 KHz
V.Frequency: 15 HZ
Model Number: GB2888UHSU
so ... now back into Windows, and extracting more such settings. 15 Hz is a bit low - and 4.44 K resolution ... is a bit much
Wow, I guess this was the most painful and lengthy hardware problem I have had in 30+ years. Again, I have learned a lot, but still:
Why do I have to extract those settings via that strange Windows tool? Why does the IIYAMA screen not report by itself which resolutions it can do?
