Washed out external monitor on M1 Mac mini on usb c

Same issue mirroring to ROKU (TCL) TV. Low contrast and washed-out colors. Sound is OK and latency is minimal. Have tried all Roku settings to no avail.

Therefore MUST BE something in the Apple transmission via WiFi. No settings on laptop apply.

Has anyone retested with 11.3.1?

Don't expect a fix soon, this is still an issue even with the latest macOS 12 beta. Apple does not seem to have much inclination fixing this issue apparently. :(

Unchecking the HDS tick box worked for me!!. Thank you!

Same issue washed out color with MacBook Air M1 (big sur 11.2.3) connected on usb-c to usb-c to LG 27UK850-W

Please Apple fix this issue is very important, I can't work all day on 13 inch monitor I need external monitor than work with correct colors.

with Same monitor and cable usb-c to usb-c works perfect with a MacBook Pro 16 (big sur 11.2.3)

My setup does not allow for do Airplay (no TV nearby - I do have both Samsung and Apple TV, but they are really far away) and I take my macbook pro in and out and in different rooms. So, doing it few times a day is not sustainable.

Hmm.. Maybe I should be more descriptive.

1. Macbook Pro M1 with LG 4K as external display on Display Port. Extended display mode.
2. Went to Display setting and changed Airplay Display setting from "Off" to go to My Apple TV. and used Mirrored mode.
3. THe display went to 1080p scaled mode. Colors stayed washed out
4. Disconnected from Airplay. Color stayed washed out mode. changed back to extended mode. COlor stayed washed out
5. closed the lid and opened back again.
6. Color stayed washed out.

Looks like I am missing something...

Same issue here. Brand new M1 Mac mini. Two brand new LG32QK500 QHD Monitors straight out of the box. HDMI connection bright and sharp. USB-c (Via HDMI adaptor) muted, slightly blurrier, different screen temp.

Swap cables - the one connected to usb c is always poorer looking. Tried every solution suggested, same result. Settings on each monitor are identical.

Shocked that this is still an issue this many months on. Come on Apple. I know you aren't the same as you used to be, but this is pretty weak.

Thanks to all of you out there who have contributed to possible solutions!

This is not an ideal soution. Most USB-C monitors carry data (for a bulit in USB hub) as well as video. You'll loose that functionality. In case of a Macbook you'll also loose the charging capabilities of your USB-C display as well. So no more single cable docking for you. Thanks Apple!

Giving up on Apple regarding this issue is understandable but it's till a shame that a tech company cannot make something as fundamental as this to work properly.

I too have had this issue since I bought my M1 Mac Mini 10 months ago - I've put up with the issue because it tends to be quite intermittent. I have two 4k displays hooked up (BENQ EL2870U's), one via DisplayPort and the other HDMI. My main display hooked up via DP 'shimmers' and I get very fine vertical bars down the screen. I've replaced the DP cable and swapped back to HDMI with no effect. If I move windows around, it causes the shimmer to fade or get worse. It does tend to stop on its own and everything is fine. I've also tried adjusting resolution, change the refresh rate etc etc but it doesnt appear to make a difference.

Whilst i've put up with it on an 'almost' daily basis, i'd love to know what the fix will be - Can anyone else advise?

Hello All

im having the same color washed out I first installed a Dell 4k usb C 27 inch it looked horrible I then switched to an LG 600 W 27 : 4k HDMI 2.1 still the color is all washed out….. tomorrow I will try USB C port to DisplayPort cable Is Apple trying to fix this on the M1 Mac mini .?

Thanks, but useless without a link or description of "HDR". Is it a system setting or ??? Actually, this page is a good example. On my Mbook Pro running 12.0.1 the field borders and text are in such a faint gray as to be nearly invisible without expanding the text to 18 or 24 point. It's not the size, it's the low contrast ratio.,

Dear Cupertino, aging and loss of visual acuity comes to all of us eventually. Your light gray text may be pretty and pleasing to your jr. college design instructor, but...

Thanks, but my problem is not with an external monitor. It's a laptop whose screen is always light gray on lighter gray. I have to pinch-expand to read anything. Weak contrast and no borders on input fields in forms. ???

Totally agree

Have m1 air and LG27UL850-W, connected thought USB-C, colours are totally washed up
