Hi all!

I am digital nomad so using a laptop is a must for me. I am using Acer Predator with i7 processor, 32GB RAM and GTX 1060 on board. Two month ago I bought LG 27UD88-W 4k monitor to use it in my office.

What I notice is that when After Effects interface is stretched to full display it runs slower then if I use it only on the half of monitor. Basicaly it is impossible to make preview because it losing audio and I don't hear my preview.

I used HDMI, DisplayPort and USB-C cables and problem is for all of them. nVIdia says that this graphic card should handle even double 4k display resolution 😕😕

Anyone has the same problem?

I think it is not your GPU, are nvidia drivers up to date? I recommend you follow the tips for increase performance of adobe: Improve performance in After Effects

AE 'eats' only about 6% GPU and about 40% of CPU

A good monitor for timeline is UltraWide ones. But how I say, check how much hardware is consuming when you use AE to know whats your problem. Inside windows you can check in the task manager, and you can download other apps like GPU-Z to check your GPU.

All interface are slowing, or just the preview? Are you already press ctrl+shift+esc to see what is going on?

I am talking about AfterEffects default workspace stretched to 4K.

I notice that whan I scale preview down in preview window it works a littlebit faster. I am using Auto preview mode. When I dont use monitor I work with Full HD (native laptop display) and I dont need to use Auto and I can preview in Full mode wth ease.

Other software works normal like browsersm spotify etc. and they dont influence AfterEffects work speed.

Hi Peter

The AE GUI is VERY dependent on the GPU so stretching it to a 4K resolution will undoubtedly affect speed and cause lag.

This is why in studio we always use 2 GPUs. One to drive 2 monitors left and one for 2 monitors right (this is in a 4 monitor setup)

Remember that your laptop GPU has to deal with the 4K external monitor as well as the normal display which puts a lot of strain on it.

What I would do is disable the output on your laptop screen and use just the LG. If thats not an option use the LG for the preview window only and leave the rest of AE's GUI e.g. timeline etc on the laptop.
