I work on a quite large 4k UHD display all day and I often had the issue, that I wanted to share my screen with attendees of different collaboration products. Then the display resolution of 3840x2160 pixel makes my screen very tiny on the remote displays and attendees complain about it.
So I normally go to the desktop, do a right click and change the resolution. Very annoying when you have to do that multiple times a day (and switch back after the meeting).
On Linux I made some scripts to change the display resolution and I can even run them automatically when I start with or without an extended screen. Sadly, I have to use other operating systems too. Which options do we have on Windows?
I found some PowerShell scripts, some EXE files, but one was not working another needed a license for non-personal use. I ended up with http://tools.taubenkorb.at/change-screen-resolution/#download it is offered to download for free and just asks for a donation.
Furthermore, I copied the script to my desktop and created two cmd files:
ChangeScreenResolution.exe /w=3840 /h=2160 /d=0
ChangeScreenResolution.exe /w=1920 /h=1080 /d=0
Now I just need to double-click the script, and it changes the display resolution. Saves me just one minute each time, but the feeling is just great.
