You are experiencing this running the macOS Ventura (13.0) public beta? If so, I suggest reporting this behavior to Apple. See this iMore article: How to send feedback to Apple about macOS betas |
Yes, that's happening on macOS Ventura. OK, I'll report to Apple. Thank you. |
|
Thanks! Please let us know what Apple as to say. One possibility is that this macOS feature is malfunctioning in Ventura: Hopefully Apple will explain the behavior. |

beta2 still sucks... cannot watch HDR video in fullscreen, only works in window mode |

Thank you for reporting this. It is helpful for the IINA project to know that there is trouble when running under the Ventura Public Beta. However the point of macOS Beta releases is for Apple to gather feedback. Have you reported this behavior to Apple as well? From Apple Beta Software Program FAQ:
Ventura Beta 2 was mentioned. Beta 4 is out. Definitely upgrade and see if Apple has fixed this. Apply may not have as I did not find anything that could explain this behavior in the macOS 13 Ventura Beta 4 Release Notes. What you are reporting seems to be slightly different from the first report which is reporting dimming when "when the mouse stops moving". Your report seems to have to do with "full screen"? Does dimming stop when in full screen and you move the mouse? Are you also using one of the new MacBook Pro's with the XDR display? This is not my area of expertise, but here are some thoughts anyway... First, watch out for IINA's HDR issue where it randomly fails to enable HDR. You can tell if IINA enabled HDR by looking at the IINA has two forms of full screen. Under Make certain this feature is not triggering: If the brightness is limited on your MacBook Pro with Liquid Retina XDR display or Apple Pro Display XDR. Confirm you do not see the warning symbol shown in that article. There are two macOS preferences that I know of which control screen brightness. At least that is how it is in Monterey. This preference: Change your Mac display’s brightness. And this preference: Change Battery preferences on a Mac notebook. In Monterey this looks like: And: Does turning off these preferences make a difference in the case at hand? |
Yes. My situation is when I turn "full screen" and the mouse stops moving, the screen dims. And this problem only happens when I play the video, if I pause the HDR video, the screen does not dim. Are you also using one of the new MacBook Pro's with the XDR display? Yes, my model is Macbook Pro 14 inch. IINA has two forms of full screen. Under Preferences..., General, Behavior look for the checkbox Use legacy full screen. Does changing that preference change the dimming behavior? Confirm you do not see the warning symbol shown in that article. Automatically adjust brightness True Tone: Turning off these options does not fix the problem. I try to feedback to Apple, but they do not give me any response. |

@HurstSi Thanks for the update. Some of my questions were directed at @poorest1212 whose report did not mention the type of Mac and other details. Good that you filed a report. The more an issue is reported the more likely it is that Apple will look into it. The tests you ran ruled out a bunch of possibilities. Unfortunately that leaves us waiting to hear from Apple. |

I don't know English very well, but I found a solution in the iina settings and it doesn't affect the viewing experience. Preferences--->User Interface--->OSD--->Display system time and battery in full screen. Can solve the problem of sudden darkening of full-screen HDR video playback. |
|
@CarterLi, any ideas on this issue? |
|
Seems to be a system bug. OSD should not affect HDR modes whatsoever |
|
Same issue here. m1 pro macbook, macOS 13.0 beta 5, iina 1.3.0, playing 8K HDR video on external monitor (Apple Studio Display). |
|
Found a solution under preferences>advanced>use mpv OSD. It helped. |
|
I had a similar problem in MacOS Ventura and this solved the problem for me. Go to Settings > Display > Advanced
This was under battery settings in the previous MacOS versions. |
|
This is issue still exist in Ventura stable build. Looks like Apple didn't fix it. I tried both mpv osd and disabling dimming in battery settings and display settings. Nothing works as of now. |
|
Same here, really really annoying. I've fedback an issue to Apple public beta, provided further information required by Apple, but still no update yet |
|
Also having this issue. MacOS 13.0 (22A380). |
|
I have upgraded to Ventura. The problem reproduced for me. Playing the same HDR test file that was working fine under Monterey results in an image that is so dark it is hard to see anything under Ventura. Investigating... |
|
This same problem is reported in multiple issues. Closing duplicates in favor of the first report of this problem in issue #3844. |
This workaround also addresses another macOS Ventura regression where an external monitor goes black, #4015. This same dimming problem was reported in issues #3880, #4013 and #4014. The workaround changes the windowDidLoad method of MainWindowController such that when running under macOS Ventura it will add a tiny subview with such a low alpha level it is invisible to the human eye. Issue #4015 has been reproduced without IINA, so we are certain this is a regression in macOS 13. At this time we do not know the root cause and can not explain why this workaround works.

It doesn't matter if the source is HDR or SDR. When I viewing a image/video that gets to a dark scene or black background, the screen dims slowly, even with all the auto brightness settings turned off. It usually happens while I'm in fullscreen. I was able to recreate this by viewing a black background video on YouTube, and the only way to fix it was to decrease the brightness and then turn it back up. Shouldn't have to do this, it's really annoying! Anyone found a fix for this yet? Thank you. |
System and IINA version: macOS 13.0 iina 1.3.0
Expected behavior:
The screen should keep its brightness level.
Actual behavior:
When playing HDR video, the screen automatically dims when the mouse stops moving.
Steps to reproduce:
Paly an HDR video on MacBook Pro 14 inch's screen.
How often does this happen?
everytime
