Zorin 15.3 not recognizing 4k HDMI Monitor

No, just as a way to organize the installation of the kernel, was all.

I guess there is no solution to this? I would be happy if someone can help in how to transfer drivers from Manjaro to Zorin, although I have a feeling that I should be using Manjaro for now and switch to Zorin later if future upgrades fix those modern drivers issues. I hope so.
Thank you to all, great help and learning curve

It goes to show we are stretching the limits of what we know.
I do need to stress: Manjaro and OpenSuse would be using the Same Drivers or kernel that we can get. They do not develop either of these.
What this tells us is that they may include additional packages like patches and that is what we want to know.
Without downloading and dissecting one of these Distro’s cannot know for sure.

Just done a search to see what ‘patches’ Open SuSE and Manjaro use for 4k and stumbled upon this:

Don’t know if anything in the article helps.

I wish I know how to dissect one of those things, but I am beginner at linux when it comes to it. If someone wants to lead I am happy try.

Interesting, but I have a feeling this is not up to HDMI output but drivers. At the moment I have Manjaro or I can install Zorin again… .if someone knows how to put those desktops onto manjaro or zorin I am happy to try, but I dont think this is the case.

The article does not refer to HDMI output, but to HiDPI monitors, which relates to your issue.

Interestingly, Cinnamon is on that list. Which is what I am using and I have had no such troubles, in spite of our hardware being very similar. Could it be a Desktop Environment issue instead of a Kernel or Graphical driver issue? That seems plausible.

I am total noob to linux insides, but I am somehow 99.9 percent positive this will not work. I am happy to install Zorin again and try.
So do you you use Zorin and Cinnamon on top? I didnt try that yet, but I base my conclusion from more and more experience and reading as well as from experience from installing at least 10 distros in the last few months.

We are not exactly in disagreement. I would say I am closer to 79%.
Yes, I use Zorin LITE with Cinnamon installed - in a particular way, I might add.
If you would like to give it a shot just for kicks, you will need the Embrosyn repo. Do not use the Ubuntu Repo to install Cinnamon.

sudo add-apt-repository ppa:embrosyn/cinnamon

sudo apt update

Then, install the pieces in this order:

sudo apt-get install cinnamon

sudo apt-get install cinnamon-common

Once those are complete, then

sudo apt-get install cinnamon-desktop-environment

Ok, will try sometime today, btw, can I install normal Zorin core and rest of procedures?

yup…

Just thought I would let you know that I installed MATE Tweak (mate-tweak) in FerenOS and go the option to change monitor scaling to HiDPi but little point as I don’t have that monitor - on the downside it added Gnome 2 Panel theming over the KDE Plasma Panel - same result in Cinnamon DE on Zorin Core because it was not running Ubuntu MATE.

Just did installation, not much luck. I have attached screenshot with system info that is clearly visible that Zorin found all drivers (seems to me). But something else is missing? Hdmi? Not a word. or something else.

You are certain that Secure Boot is disabled, right?

EDIT in… TOo many tabs at once, I cannot find the thread I was reading that suggested this, but somewhere, someone said to put in terminal:

xrandr --output “nameYourHDMI” --mode “yourResolution”

You will need your monitor ID to name your hdmi.

quick update, just upgraded bios as well, but seems same, secure boot is disabled

How do I know what my monitor is id? Do I run manjaro from USB to find out?

Usually with

xrandr -q

That has not worked before…
If it is HDMI, it usually is just listed as hdmi1
You could try

xrandr | grep " connected " | awk ‘{ print$1 }’

Just for kicks- ensure that python3 is installed.

Happy to install python, one of the main reasons I want to use linux more and more
