Non-standard resolution 1900x1200

I have Manjaro 20.10 xcfe installed on Khadas VIM3 box.
The issue I have that on 1900x1200 resolution via HDMI port I have vertically shifted up image and not possible to configure something on monitor with this signal.
Are there any ways to calibrate an image on Manjaro or to try manual hdmi configuration for this resolution?


Via DVI port an image located correctly, but no audio(as it’s not HDMI)

:+1: Welcome to Manjaro! :+1:

You’ve taken a picture of your monitor to show the artefacts.

  • Does this also show up in a screenshot?

If no: Sorry, this is a monitor issue, please update the monitor’s firmware or use another resolution

If yes: Please read this:


and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

:+1:

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you’re using, which CPU/GPU you have, …

Screenshot looks normal.
So looks like it’s monitor issue.
Are there any ways to add manual resolution/frame rate? (not only that EDID have)

Yes, please provide:

  • the output to xrandr
  • the technical specifications of your monitor (resolution and frame rates missing from the xrandr output) as that will allow us to define custom resolutions.

P.S. Your profile section still looks as empty as the Sahara desert… :grin:

Monitor is Samsung T260HD, and all resolutions and refresh rates looks correct

There’s nothing I can do from a Manjaro perspective that will be perfect as the monitor is detected fine on both ports.

What’s the output of:

cvt 1920 1200 74.25

I.E. We’re going to try running that resolution at the next lowest common denominator frequency and might be able to scale up from there (but not guaranteed)

P.S. You’re not using a passive converter as I’m unfamiliar wit the Khadas VIM3 HW, are you?

[vim3@vim3 X11]$ cvt 1920 1200 74.25
# 1920x1200 74.17 Hz (CVT) hsync: 93.08 kHz; pclk: 242.75 MHz
Modeline "1920x1200_74.25"  242.75  1920 2064 2264 2608  1200 1203 1209 1255 -hsync +vsync

I just tested on other monitor(that have bigger resolution UWHD) and tried 1920x1200 resolution on it without any issues. I think that something with firmware of my old monitor.
But if anything will be for test then I’m ready.

I don’t know nothing that you mean about converter.
I just use cable HDMI-HDMI or HDMI-DVI. HDMI part from Khadas VIM3 box, HDMI or DVI from monitor side.

  1. That’s the first thing I said:

    :grin:

  2. That one is a converter :scream:

  3. As we’ve come so far anyway, try:

    xrandr --newmode  "1920x1200_74.25"  242.75  1920 2064 2264 2608  1200 1203 1209 1255 -hsync +vsync
    

    If that doesn’t give you an error message, try using the 1920x1200_74.25mode.

    • If that fails, use the other monitor… :sob:
    • If that works, press the 3 dots and the Solution button below this text. :grin:

I tried but no, monitor doesn’t support such refresh rate. Monitor is too old and no any firmware available.
In any case thank you for your time.

No worries, I’m going to repeat what I already said a few days ago and mark that as a solution:

Sorry, this is a monitor issue, please update the monitor’s firmware or use another resolution / monitor

:sob:
