Premiere Pro Monitor Lag

[rindahlm]

Hello all! Recently I have started editing on an external monitor connected to my laptop. I have noticed a very common issue that when I playback the video from the timeline, the video is very glitchy, not like the normal lag/glitch when it isn't rendered. I have played FHD 60fps video on this monitor and it works great but when I am watching or scrolling through the timeline, the video playback it is still glitchy. Premiere runs perfectly on my laptop however. I am running on a XPS 15 i7-7700HQ, 16GBs of Ram, GTX 1050ti and my monitor is an LG 29um57-p. My current version is cc 2017 Anything helps!!

Thank you,

Matt

Two things come to mind - either the video card is lagging driving two monitors (unlikely for a 1050ti) or perhaps the monitor is running at 30hz instead of 60hz.

thanks for the response, however the monitor is running 60hz

I just remembered I had laggy performance with certain apps on my 9550 as well (haven't run Premiere on it yet). I figured out it was because the notebook was not always using the discrete graphics vs the slower integrated graphics. As a quick check to see if that's what is happening for you, right-click on the desktop and run the NVIDIA Control Panel. Go to "Manage 3D settings" and in the Global Settings tab change it from "Auto-select" to "High-performance NVIDIA processor".

If this fixes your issue you can refine the resolution by switching the global setting back to "Auto-select" and then using the "Program Settings" tab to make the change specific to Premiere. That way you wont waste power when on the battery when not running Premiere.

I just tried this, didn't work, restarted my laptop just in case and still didn't work /:

Try disabling the laptop's internal display (F1/Fn+F1 I think), running just the external monitor, and see if that makes any difference.

Didn't work, however, when I duplicate the displays it does work but that's not what I'm going for, and it doesn't fill up the entire monitor screen. I hope this info can help

[Horshack]

Ok. Try reducing the resolution of the external display to the lowest resolution possible and see if the lag disappears.

[rindahlm]

it gets to be a little less noticeable but still there

[Horshack]

I have to think it's down to the 2D processing power of the GPU then, in combination with potential inefficiencies of Premiere's screen drawing logic.

I am having the same problem

It could be the drivers. Some work some don't.
