Question

Premiere pro lags when using external display (slow) - M1 MAX MBP

Hello,

I use Premiere Pro on my MBP 16" M1 MAX, and I like to edit on my secondary display, an LG 4K, using a USBC -> HDMI cable. For the past few days, I've noticed that, when I use PP on my external display, everything lags. Even clicking on a menu button takes 5 seconds to appear. It's not a preview problem, but more a general slowness.

When I drag/drop back my main PP window to my built-in display, everything's becoming normal after few seconds...

Do you know where this problem can come from?

Thank you!

    I'm having the same problem. When using PP on a secondary monitor, the interface becomes extremely laggy. This doesn't happen on the main monitor. It doesn't matter if the secondary monitor is on or off. I have two different secondary monitors from different companies and the lag happens on both. I have an Intel Mac (iMac Pro) so it's not only with M1.

     

    This happens with various codecs and even with 720p proxies. It doesn't seem to be footage dependant. The playback is fine. It's clicking through the Timeline that gets super sluggish.

     

    It's only in Premiere. Other applications work normally on all screens.

     

    Specs in the attachments. Using PP 23.1.0

     

    Thanks for your help.

      Guys just so you know, Just turned my external monitor into the "main Screen" for the system and it works more fluidly. I would say is still not 100% perfect but it improves a lot. 😃 

      My system attached below and with Ventura, and the monitor is a BENQ SW270C 27"

        Bug is still there. Not only on M1 Max, but also on M1 Pro. Premiere runs butterly smooth on macbook but with the 4k Monitor plugged in, I can't even import a single short clip without delays and lags. I already tried PP beta, same issue. Final cut and davinci works fine with the monitor plugged in.

          is feels more like a system issue rather than PP issue. double check that you have all the latest drivers installed, especially the GPU.
          Try also changing the cable you use to connect to the external monitor

          I'm guessing it is M1 related. Does this issue happen when you run Pr via the Rosetta 2 emulation?

            Thanks mate, wasn't aware of the uservoice forum. I've posted the issue there. And yes, no issue when running under emulation.

             

            https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/44975842-premiere-pro-input-ui-lag-on-m1-based-systems-u

             

            "Hi

            There is noticeable input lag on m1 based Macs when using an external display. There are quite a few threads on the community forums.

             

            I can replicate the issue on an m1 Mac mini and a m1x max MacBook Pro. Mouse clicks can take a few seconds to register.

            Ive tested swapping out the cables connecting the display & connecting the display via usbc and hdmi.

             

            The issue seems to be specific to the native version of premiere. There is no input lag when running the intel version of premiere through rosetta 2 emulation. Also, when switching back to the native version of premiere, the issue will be resolved temporarily but will reappear in a few hours.

             

            It's also worth noting, there is no input lag when using the native version of media encoder, but there is input lag when using the same windows when exporting directly from premiere.

             

            Hoping for a fix.

            Thank you"

            I have the same problem with an m1 max/ 32gb ram and a m1/ 16gb ram. Premiere has a noticable input lag using a monitor connected over HDMI. Lowering the resolution and/ or refresh rate helps but does not elimanate the lag. Desperate for a solution for this.

            you might consider trying using this

             working great on an m1 macbookpro (which doesn't allow connecting a second external display otherwise).  Got one external display connected via a owc thunderbolt hub via minidisplay port on the hub and a second external display play program or source via this unit.  also works great with resolve...  Don't know if it will solve your performance problem with an external display but maybe worth a shot at a very reasonable price particularly if you can return it if it doesn't meet your expectations.

            Good suggestion, but only supports 1080 60p, I think the problem lies with higher resolution external displays and premiere.

            I have the exact same problem with an LG ultra wide monitor that isn't 4k, and I'm running a 16inch M1 Max.

            It only started happening after I updated Monterey and Premiere to the latest versions.
