Mac mini with redmi 4k 27 inch first gen? (Bought on Double Eleven in 2023) HDMI is gray, type-c is clear

As titled Do you have this phenomenon? I took a look at the hdmi port of this monitor and it is 2.0 (the hdmi association has changed the protocol definition, which is somewhat similar to USB3.1gen 1, hdmi2.1 low bandwidth version) There is no shortage of messages saying that hdmi does not support 4k 60Hz 10bit Before this I used the black apple dp interface I love dp so much And now either use the c port and then pull it out when using the notebook Or you can only add a docking station with dp, which will look more cumbersome Why can't Mac mini give a dp port as a host (because typec has a dp signal, right)

I use my MacBook Pro m1pro hdmi connection, and there is no problem with graying color. Looking at it, it may be a problem with Mac mini, but it is hard to say, connecting Sony TV does not have this problem

https://gist.github.com/GetVladimir/c89a26df1806001543bef4c8d90cc2f8 Just let hdmi force output rgb 8bit format Note that at the end of this tutorial, you should delete the com.apple.windowserver.displays xxxx file in/Library/Preferences/ByHost

I would like to ask, how can I check whether the Mac is connected to the Sony TV, and whether the input into the TV is YCbCr color or RGB color format

@ Poster Thank you friend, BetterDisplay has already been installed, and the 3.0 released in August implemented the viewing color output format. I mainly want to know how to check the color format information currently used on Sony TV. When I look at other V friends' LG TVs, I can view the color format.
