Zorin 15.3 not recognizing 4k HDMI Monitor

Hardware Support
#84

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

#85

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

#86

yup…

#87

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.

#88

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.

#90

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

Just installed PycharmCE and run Helloworld, that seems Python 3 is installed? Right?

This thread should win the biggest thread in the history of this site badge, holy moly. :stuck_out_tongue:

OK, peanut gallery comment finished, get back to your regularly scheduled program…Unless…

And now for something completely different!

Hahah, I just got home (as wifi drivers do not work) connected to wire and from Linux I can see this doggy above, but from Windows is invisible unless you go to new tab.
Moral of the story, go Linux

#100

I have tried some of the procedures, but most of them I don’t even know how to do it due to my limit knowledge of Linux. I have a feeling I will go Manjaro and can put Cinnamon or other desktop environments. Btw is there any testing benchmark Linux app that I can use for testing speed of Linux OS?

#101

i haven’t used any of these but maybe they’re what you’re looking for? https://www.fosslinux.com/42630/best-cpu-stress-test-performance-benchmark-linux-tools.htm
