I see in the gui version RDM.app, that it lists the same things in the menu bar. Its a lightweight Mac app that can bypass Apples limits on native resolutions and enable all the resolutions your display really has to offer. It's an old program, so I expect these are that the OS allows. It doesn't seem to include the specific resolution the OP was looking for though. I didn't try the gui for it but I used the terminal command. How can I keep the host computer from changing the screen resolution on my Mac I am running Parallels with windows and it changes the resolution. I just tried RDM as recommended by above and it is working. It's always the same, a very cool device, but Apples dictatorship. This is really the last and makes Apple really unsympathetic! Where is the problem to let a user decide which resolution he wants on a device he paid for?!? Why do you always have to jail everything and take freedom away?! That makes me so mad, I would like to throw the MacBook in the trash. After installation, you then click System Preferences > Other > SwitchResX > select your Mac / Monitor from the right column -> Custom Resolution > and. I need this solution for my daily work to earn my money and Apple thinks that they have to patronize their users, technically without any sense and reason. Apple Care, I would expect that I can at least adjust this little thing as I want it to be?! So for me the MacBook Pro with Apple Silicon is a total bad buy. For me and many other users this is unacceptable behaviour and completely destroys the Mac experience. Currently these isn’t working anymore on Apple Silicon MacBooks. Why do you have to cut us users more and more? Since 2013 I use a custom resolution of 1920x1200 HiDPI on my MacBook Pro 13' with help of SwitchresX.
