External HDR monitor doesn't work properly after MacOS 12.3.1 and MacOS 13 Hey the community. I think a lot of mac users had the same issue as I'm facing. When you plug an HDR monitor into your Mac with the system version of MacOS 12.3.1 or newer version even 13.0.1, the HDR model won't work properly. Issues: HDR content can't be displayed in HDR mode. The screen is grey and yellow. While the internal display of Macbook Pro 2021 M1 is working great and displaying HDR content great as usual. Hardware: Macbook Pro 2021 M1 pro. Innocn 27'' HDR M2U minotor. Thunderbolt cable. Software: MacOS 12.3.1 and MacOS 13.0.1 IINA player. I'm sure the Monitor is fine as it works with my iPad Pro m1 and my Windows PC. HDR content displayed in it's correct way. I tried to communicate with my monitor manufacturer but they didn't find issues from their end. I tried to tickle the setting: When you try to change the "color profile" in display setting, it will correctly display the HDR content for 0.5 second and then goes back to gray and over-bright screen. Check the video for example👇🏻 https://youtu.be/djSux5W4QKo I tried to find something useful from the Community, but no, nothing was found. It looks like a system bug. 12.3.1 or later system break the support. :-( And I found this discussion in IINA github: https://github.com/iina/iina/pull/4017 Anyone else having trouble with HDR in ma… - Apple Community

MacBook Pro M4 Pro Not Recognizing External Monitor via Thunderbolt (Worked on M1 MacBook Pro) I’m experiencing an issue with my new MacBook Pro (M4 Pro chip, running macOS ) where it’s not recognizing an external monitor via Thunderbolt. The M4 Pro should support two external displays—one via Thunderbolt at 6K 60Hz and one via HDMI at 4K 144Hz—but I’m unable to get Thunderbolt to work. Details: MacBook Model: MacBook Pro with M4 Pro (purchased in Januaru 2025). Monitor: Alienware 34 Curved QD-OLED (AW3423DW), resolution 3440x1440, with 2x DisplayPort 1.4 and 1x HDMI. Connection: Thunderbolt port on MacBook to DisplayPort 1.4 on the monitor using a USB-C to DisplayPort cable. Issue: The AW3423DW is not recognized when connected via Thunderbolt. It works fine via HDMI (3440x1440 at 100Hz), but Thunderbolt connections show no signal, and the display isn’t detected in System Settings > Displays (even after clicking “Detect Displays”). Key Detail: This exact setup (same cables, same AW3423DW monitor) worked perfectly with my previous M1 MacBook Pro, supporting 3440x1440 via Thunderbolt-to-DisplayPort. The issue only started after switching to the M4 Pro MacBook Pro. Troubleshooting Tried: Tested all Thunderbolt ports on the M4 Pro MacBook. Confirmed the cable supports video output (worked with M1 MacBook Pro). Swapped with another USB-C to DisplayPort cable (also tested successfully with M1). Verified the monitor’s DisplayPort input works with other devices. Updated macOS to the latest version as of March 16, 2025. Additional Setup: I also have an Alienware AW2723DF (2560x1440) connected via HDMI to the M4 Pro, which works perfectly. The problem is isolated to Thunderbolt connections on the new MacBook. Given that this setup worked flawlessly with my M1 MacBook Pro, could this be a hardware issue with the M4 Pro’s Thunderbolt ports, a compatibility problem, or a software configuration difference? I’d appreciate your help in diagnosing and resolving this!

Problems with external monitor after upgrading to Ventura. After updating my 2020 macbook air M1 with Ventura I can no longer use my 4k LG 27UL500-W monitor, it gives me 1080p as the default resolution and when I rescale it to 4k from the settings, it also scales all windows, folders and docs making it impossible to use (all too small to be remotely usable). The set up is exactly the same as before the update, so it's definitely not a problem of how the monitor is connected with the pc (HDMI with an original apple adapter). I hope something can be done about it. Thank you very much.
