Green tint on external monitor in fullscreen

I have this problem with Mac Mini late 2012 when watching TV app in full screen on a television with HDMI. If I move the mouse or play subtitles then everything is normal but as soon as the transport controls disappear or the subtitles disappear the display turns green.

I found that going into system settings > accessibility > display > cursor, and then turning off "shake mouse pointer to locate" completely fixed the problem.

Solved by disabling hardware acceleration in chrome's advanced settings

For me the problem recurs occasionally. Each time it does I just go to:

System Preferences > Accessibility > Displays > Cursor,

I then set Cursor Size to Normal.

Fixes the problem every time.

Even if it was already set to Normal, I just slide the Cursor Size slider away from Normal and then back to Normal and that fixes it.

Such a silly bug. Hope this workaround works for you.

On the external monitor reduce the response time to standard or faster i kept mine to standard. On my Samsung external monitor there are three options: standard, faster and fastest. I had mine on fastest thinking the video performance would be enhanced but this wasn't the case. I even searched on google telling me to turn off Hardware-accelerated video but this did nothing.

Hopefully this helps.

Yes, that works on my 2020 13" MacBook Pro! Thanks

I had the same problem on my MacBook Air 2020, what I did was to disable Night Shift and the issue has gone.

Hope this help you all.

For this solution of going into system settings > accessibility > display > cursor, and then turning off "shake mouse pointer to locate", I have also found that the problem can recur in which case toggling “shake mouse pointer to locate” back on Fixed the issue again. So try both.

also others have reported that the slider control for Cursor Size in this menu area can also fix the problem. Try moving the slider and then setting back to “Normal”.

with regards “Graphic switching”... I would expect this option to only show Within the Energy Saver menu if you have both dedicated and discreet graphics cards built into your MacBook. however since you mentioned your MBP 2020 is a 13” I believe yours only has the one dedicated graphics built in. Since there is no other card to switch between you won’t see/have the option you are looking for.

I also have this same exact question. Just got my new Mac Pro 13' 2020 two weeks ago. Everything is fine until I watch a video on full-screen and there is a green tint. Played with energy saver preferences but no luck. Are there any updates on a solution?

this works!

Incredible. The mouse thing solved my problem. I don't know why, but it did. Thanks.

Works for me too. Thank you!
