4k60Hz - Best way? Mac Mini M1

[SpitUK]

I know there are issues but anyone know whats going on here....

I use a Samsung 4K TV Q60 43" and it worked great with my previous 16" MacBook Pro and also my Windows machine.

Plugging in the HDMI 2.1 cable I used on windows results in a washed out image and fonts not being very sharp at 4K 60Hz (seems to be a known issue).

I got this cable:

uni USB C to HDMI Cable (4K@60Hz, 2K@120Hz) Type-C to HDMI 2.0 [Thunderbolt 4/3 Compatible] for MacBook Pro/Air, iPhone 16 15, iPad Pro, Surface Pro, Pixel Book, Galaxy S10, and More-Grey-1m

Immerse yourself completely in 4K Ultra HD within your entertainment space. Just plug it in and tap in the game. Extra durable and extra freedom. Minimize interference. High Definition HDMI 2.0 Performance. 4K@60Hz High Resolution Nylon braided cable, advanced aluminum housing. Recommended by a t...

Everything is much sharper now via USB-C to HDMI but max refresh is 30Hz.

Anyone tried another cable or do I need a dock like this:

Plugged it in to the next Thunderbolt port and now get 4K 60Hz! Still not a great image, washed out on the icons and oversaturated. Looks to be the RGB and ycbcr issue people are having, what a crazy situation.

"Still not a great image, washed out on the icons and oversaturated."

Have you tried:
1. Open display pref pane
2. Click "color"
3. Hold down the option key and click "calibrate"
4. Follow through to create a new profile?

Tried that thanks. The main issue is that all images look heavily compressed, on windows they are hi res images....

4K 120hz on my LG C9 55” OLED no 60Hz here.

The M1 supports 120Hz? Do you get RGB as well?
