Didn't work for very long, my M1 Mini was back to YPbPr when display came back from sleep and also resolution reset. I scaled back the resolution, restarted and RGB again, very strange. We need a permanent fix, computer monitors should not default to YPbPr and we should not have to fiddle around trying to get RGB.
Got a tip for us?

Anyone have a monitor that can run in RGB color mode with Mac Mini M1?

sorry if this is a stupid question, but isn’t this possible if you connect via usb-c? Thinking of getting this monitor too.
I agree, initially I thought text looked slightly sharper in RGB mode. But after switching back and forth I cannot not see any noticeable difference (at least for me). In RGB mode I also get 24 bit color vs 30 bit in YPbPr. Anyhow at least now we know
happy to put this behind me and enjoy a great monitor.......
I returned my U3219Q (YPbPr issue, reddish-brown backlight bleed, a bit too big) and picked up an LG 27GN950.
My M1 MacBook Air runs it at 4K 144Hz very nicely over a USB C to DisplayPort cable thanks to Display Stream Compression.
On my PC with an AMD RX 5500 XT it goes all the way up to 160Hz, not sure why the Mac can't do that.
There is no explicit indication in the OSD that the signal is RGB, but I have found no evidence on the 'net that LG displays support YPbPr in any way.

Plugable USB-C to DisplayPort. I was surprised it worked without the 8K designation or whatever, this thing was $17 on Amazon.
Size and colors are great. Gaming and desktop use at 144 or 160 Hz is nice. But it has an annoying fan! Based on reviews, I think I just got a bad unit.
The LG does not show anything in the OSD, but I think this panel in Mac OS has the answer under "Space":
Update:
I connected my old U2713HM to the M1 as a test. The display is receiving YPbPr yet the profile still shows Space: RGB which seems wrong.
Maybe the bug is such that Mac OS both sends the wrong signal and thinks it's sending the right one?
Thanks for the update. I think the M1 just always output YPbPr color space to any external monitor currently ... I read something on Github https://gist.github.com/adaugherity/7435890 where it seems to be a consensus on the bug, whatever the monitor is.
I think it’s only Dell displays. If you Google “Mac YPbBr” all the results are Dell problems.
I've read problems with LG too (Dell uses LG panels after all) and Acer monitors (maybe they use LG panels too?)
Dell monitors are common, so I'm not surprised it's the first to be sorted out with problems on search engines.
True for panels but the more important component for signal negotiation is the scaler chip and associated logic controlled by the OSD.
I just realized that my Dell U2414H outputs in YPbPr. Using Intel MacBook Pro Late-2013 15 inch. It always been in YPbPr it seems since ... the last 6-7 years LOL.
Running it in DisplayPort makes it switch to RGB mode.

Not so sure about that, some reports indicate the issue may have started in Catalina (I doubt you can be bothered to boot an older OS to check
)
I have Catalina installed too. Trying.Not so sure about that, some reports indicate the issue may have started in Catalina (I doubt you can be bothered to boot an older OS to check
That is good to know, but "started in Catalina" means we'd have to try Mojave... which I could do. God, why did I ever leave Mojave, it was perfect.
But I cannot see the difference in colours between both inputs.
That's weird... With HDMI it's YPbPr. With DisplayPort-to-MiniDP/Thunderbolt2, it's RGB.
But USB-C implements DisplayPort, isn't it ? And people are saying here that using USB-C cable it falls on YPbPr mode...

what about multiple monitors ?
Is one would be in RGB and the other one in YPbPr??
And if we extrapolate and say LG users just doesn’t have any way to verify the input signal on their monitor, they might be also running in YPbPr without knowing it.
