Hello everyone!
I would like to use Zorin OS and tried it before installing. Unfortunately, the display scale is too large (200% in the settings). I would like to use 150% which fits best (as in Windows). Is there any way to change the scale to the desired value?
Thank you!
Many folks have asked for this exact thing, and to be honest, I would like to have that as well. I personally am using 200%, cause 100% is too small, on my 32" 4K monitor.
Welcome to the Forum!
There is a simple Way to get that but You have to look if it works well. Go to Settings>Displays and activate Fractional Scaling:
Then You should get above a Dropdown Menu where You can choose 150%. But be warned: Fractional Scaling isn't well implemented and because of that it might not work well.
Hey!
Thank you for the answer and welcome! 
I have enabled that option but it doesn't display other values somehow. There is still only 100% and 200%.
Does it work when you switch to XOrg?
Logout and at login click on your username, then a cog wheal appears at the bottom right corner. There select "Zorin Desktop on Xorg" and login with your password.
Sorry, I just see you haven't installed Zorin yet. I believe there is used XOrg by default.
You could try it with xrandr.
For surface computers there is a special kernel offered:
But you can't test it with the Zorin Live USB stick.
Yes, that was my research as well. Unfortunately I need to install Zorin in order to test it...
How is the performance of Zorin on the Surface Laptop 4 in general? I tried the live USB and it seems to perform well.
I'm not sure if it will work with xrandr in the live session (=Try Zorin mode), maybe it has to be installed first, and it only works on XOrg not Wayland and I'm not sure what is used in the live session and if you could switch.
First run
xrandr
to find out your screen name, e.g. eDP-1
Then enter
xrandr --output screen-name --scale 1.5x1.5
(replace the screen-name with the output of the first command)
xrandr --output eDP-1 --scale 1.5x1.5
If it performed well over USB Flash drive, which runs slower then SSD & NVME speeds, then it will perform better on metal install. I recommend usage of NVME if available, otherwise SSD is fine.
NOTE: Do not install on mechanical HDD, performance will be terrible.
So, You only use Zorin from the USB Stick? I would have suggested to reboot after activate Fractional Scaling but this will not work ...
I have installed it now and enabled fractional scaling but the text is blurry which is kinda disappointing.
Yes, as I said: the Fractional Scaling isn't so good. Did you installed Zorin 17 or the Zorin 18 Beta?
If You want bigger Font Size, You could avoid Fractional Scaling and instead scale the the Fontsize. to do that, open the Terminal and type sudo apt install gnome-tweaks to install the Gnome Tweak Tool.
After installing it, open it and go to the Fonts Tab. there you can set up the Fontsize (1) or increase the Scale Factor (2). You could play with it a bit to see if You get a for You fitting Result.
