Hello,
do you have a datasheet of that display?

Parameters in hdmi_timings are from the manufacturer?

gvolt · October 9, 2023, 4:50pm

Could you describe what problems you have?

Rue · October 9, 2023, 6:32pm

Sorry i have No Datasheet. Only this:

the display remains dark

gvolt · October 9, 2023, 6:34pm

What Raspberry Pi model do you use?

Rue · October 9, 2023, 6:35pm

Raspberry Pi 4

gvolt · October 9, 2023, 6:36pm

Is the display connected to HDMI0 (the HDMI connector next to USB-C (power)?

Rue · October 9, 2023, 6:42pm

The display is connected via HDMI and receives power via USB C. This is how it works on the PC

gvolt · October 9, 2023, 6:43pm

Yes, but which of the two HDMI ports of the Pi is it connected to?

Rue · October 9, 2023, 6:49pm

Yes

I tried that too and then I got streaks

hdmi_drive=2
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=87
hdmi_aspect_21_9=7
hdmi_pixel_freq_limit=400000000
hdmi_cvt=2560 720 50 7 0 0 1
#config_hdmi_boost=4
max_framebuffer_width=2560
max_framebuffer_height=720
framebuffer_width=2560
framebuffer_height=720

gvolt · October 9, 2023, 6:51pm

?

What HDMI port of the Pi do you use? HDMI0 or HDMI1?

Rue · October 9, 2023, 6:53pm

HDMI 1, the right port next to the USB c power port

gvolt · October 9, 2023, 6:55pm

You may try removing your current display related settings and add

hdmi_group=1
hdmi_mode=90

to “/boot/userconfig.txt”. “hdmi_mode=90” is for displays with a resolution of 2560x720@60Hz.

Rue · October 9, 2023, 7:05pm

I’ll try this out, thanks for now

Rue · October 10, 2023, 8:07am

I have change, but will not work

max_framebuffer_height=2560
hdmi_group=1
hdmi_mode=90
hdmi_timings=720 0 8 128 64 2560 0 1 3 24 0 0 0 67 0 42009500 8
#display_rotate=2 #1: 90; 2: 180; 3: 270

gvolt · October 10, 2023, 8:09am

Try without “hdmi_timings=…”

Rue · October 10, 2023, 8:17am

not working without timing

max_framebuffer_height=2560
hdmi_group=1
hdmi_mode=90
#hdmi_timings=720 0 8 128 64 2560 0 1 3 24 0 0 0 67 0 42009500 8
#display_rotate=2 #1: 90; 2: 180; 3: 270

gvolt · October 10, 2023, 8:35am

You could try replacing “hdmi_group” and “hdmi_mode” settings with

hdmi_cvt=2560 720 60
hdmi_group=2
hdmi_mode=87

Maybe also check using

hdmi_cvt=720 2560 60

P.S. Where are the values for “hdmi_timings” from?

Rue · October 10, 2023, 8:40am

I installed new ones and only used the touch display plugin.
no entries in the userconf

gvolt · October 10, 2023, 8:46am

At least a picture, albeit a little stretched.

Do you still use “framebuffer_height” and/or “framebuffer_width” settings?
