Miguel Saenz Posted June 4, 2023 Share Posted June 4, 2023 HI, you can solve this with 2 methods: method 1: Disconnect the second monitor in the installation, after the installation and final configuration connect your second monitor. Method 2: Use this information: Some users might be aware that there has been a great fix using a Ruby script to create a new EDID for your display. This is to fix an issue with some displays and Mac OS whereby it sees the display as a TV screen and is not using RGB mode for it, resulting in a very bad display quality (washed out, fuzzy, pixelated, etc). The 'old' trick with using the Ruby script and placing the files in .../System/Library/Displays/Contents/Resources/Overrides/ doesn't work any longer, even with SIP disabled as the file system is now mounted read-only. You can mount it read-write but that's a very long-winded and potentially lethal solution. The easy fix: download the ruby script: https://gist.github.com/adaugherity/7435890 in terminal, run the script with 'ruby' followed by the script location/name it will create a folder in your home directory (something like 'DisplayVendorID-XXXX...) in /Library/ create following new folders: Displays/Contents/Resources/Overrides/ copy the whole folder from step 3 (located in your home folder) to the Overrides folder you created in step 4 reboot Credits go to: https://www.mathewinkson.com/2013/0...ix-the-picture-quality-of-an-external-monitor for the original solution/follow ups, https://gist.github.com/adaugherity for the forked Ruby patch ----- I tried both methods 3 hackintosh pcs, and works fine Quote Link to comment Share on other sites More sharing options...
