Premiere playback issue when connected to external monitor

[Shelby38917724svyr]

I have a new Macbook Pro (M4 Pro Chip, 48GB memory, 1TB) and I am trying to connect it to a Dell U2723QE external monitor. The issue is that I am editing video footage in Premiere and during playback, I am getting some strange lag and issues with the image (almost a banding kind of effect during quick camera movements?). It happens on both the monitor and the macbook screen when they're connected, but when I disconnect, it looks fine on my laptop. I'm having this issue with both 1080p and 4K footage. I'm using proxies in premiere, and the issues also occur when playing the raw footage in other applications. I currently have the monitor connected USB-C to USB-C with 60hz refresh rate set for the external monitor. I also tried connecting with an ultra high speed hdmi cable and continue to have the playback issue on the monitor (though it works on the macbook).

Does anyone have any suggestions on how I might fix this?

Thanks so much.

Hi @Shelby38917724svyr,

Thanks for the message and welcome to our forums. I am sorry you have not gotten a response yet. It seems like your system can definitely support a second monitor, but you might try a different USB-C port as they do not all offer the same throughput, as I understand it. I also wanted to ask about the type of footage you are editing. Have you tried transcoding the media or using proxies? Let the community know. I hope we can help you.

Cheers,
Kevin

Hello Kevin,

Thank you for your message! I have tried using different usb-c ports on both my monitor and the macbook (and also tried using HDMI), but that doesn't seem to make a difference unfortunately. I am also using proxies. Any other suggestions would be appreciated!

Thanks for hanging in there, @Shelby38917724svyr! At this point, I would try the options in the Reset Options dialog box and let us know the results. Let me know if you need help with that.

Thanks,
Kevin

Hi Kevin,

Thanks for the suggestion! Sorry for the delay, but I've just had the chance to test this again, and unfortunately it still doesn't seem to address the issue.
