I had 2 connections: HDMI via apple connector into USB-C (plugged in) and Displayport to USB-C cable (unplugged)Ģ. I got a version of this from MacRumours's massive thread.ġ.
Sadly it didn't work for me on the DELL U3014 + M1 iMac. Thank you thank you for the M1 mini solutions. Please feel free to ask if you have any questions regarding this procedure. Hopefully this tutorial would be useful to someone.

The end result is having your M1 mac output RGB color to your external monitor instead of YPbPr, potentially making the colors more accurate and the text a bit more crisp, even on older 1080p monitors. Here are each of the Terminal commands mentioned in the tutorial, so that you can just copy and paste them: The video also has Closed Captions (Subtitles) that you can enable, to make it easier to follow if needed. To make things easier, I've created a step-by-step video tutorial of the whole procedure that should force RGB color output on your M1 Mac connected to an external monitor, and works on an HDMI-to-HDMI cable connection: While doing a lot of testing on how the Dual-Cable workaround above makes RGB to work on M1, I've discovered what changes it makes to macOS, and managed to create a more streamlined workaround without the need to use a second cable. I have some good news! Found a new workaround that should (potentially) work on every M1 Mac and force RGB color output via HDMI-to-HDMI However, this new workaround doesn't seem to rely on EDID or on using an EDID from another port. I've tested them on an older Mac mini late 2014 and indeed each port required a different override file to work previously. On my side, the Display Port and the HDMI ports each seem to have their own different EDID. My Dell P2415Q has product ID A0BE for DisplayPort and A0C5 for HDMI so my idea is probably wrong but I don't have an M1 Mac to test the thank you for the reply and for your question. Maybe that's because it's using the EDID for the HDMI port (maybe the EDID was cached and macOS chooses it because it was the first found with the same product ID)? Then when you switch to HDMI, it uses the EDID for the DisplayPort (maybe the search algorithm for the cached EDID starts in a different location so that it finds the DisplayPort EDID this time). In your original post, you select DisplayPort first which is using YPbPr. in all these successful cases of the workaround, are the product IDs the same for the EDIDs or the DisplayPort and HDMI ports of the display? In that case, what we could be seeing is macOS using the wrong EDID for each.
