Not all resolutions marked with ⚡️ (lightning) work on external display

Open louisamand opened this issue 2 years ago • 10 comments

Macbook Pro (M1), macOS Monterey 12.5.1 2560 x 1440 external monitor

Most lightning resolutions do not work. I click on it and nothing happens. The resolution stays as per last valid command. The resolutions without lightning work "fine" but are very blurry/pixelated.

So far, only those two work:

  • 1280 x 720 ⚡️
  • 1024 x 576 ⚡️ (Not even 2560 x 1440 ⚡️ does work)

Is there anything to change ?

same here, except that only 1024 x 576 ⚡️ worked for me. Not even 1280 x 720 ⚡️. Macbook Pro (M1), macOS Monterey 12.6

Maybe now this works only native HiDPI resolutions (look at Display Resolutions at 12.x and 13 Ventura OSX), very sad, I use BetterDisplay to solve this limitation, but not smoth like RDM.

Venture 13.0 - same issue (RDM not activating the HDPI resolutions) on a 4k display. Also Mac is not showing me even 1080p as HDPI anymore, blurry text :(

Do you quit and reopen RDM when you connect the external display? When you do that, RDM lists two separate monitors.

The code is not being maintained anymore. I didn’t write the code, just packaged the app for easier installation.

Had the same issue and did below steps to get additional resolutions with ⚡️ I found here.

  1. Open a new terminal window and simply copy-paste the below command.

$sudo defaults write /Library/Preferences/com.apple.windowserver.plist

DisplayResolutionEnabled -bool true

  1. When you have completed the 1st step, press the ‘Return key’ to run the command. However, since it is a Sudo command, you need to enter the Admin password. Apple, and we hope the Mac is yours!

  2. At last, reboot the device for the changes to take effect.
