After Effects CC 2017 very laggy on second monitor

[milesv75082441]

Hello!

I just bought the Acer H7 (H7 | Monitors - Sharp visuals, progressive styling | Acer ) monitor to use as a external monitor for my laptop, and I would like to move the entire AE window to it. However when I do so, my actions become so sluggish that its unusable. Other software (like Premiere) seems to be fine when used on the monitor, so I'm not sure what the problem is. The preview monitor for AE will never play in real time on the ACER, but the same project will be fast on my laptop monitor.

I have a Lenovo Thinkpad P70

Windows 10 Pro

Intel Core i7-6700HQ CPU @ 2.60 Ghz

Samsung 950 Pro SSD 256gb

NVIDIA Quadro M3000M

16gb DDR4 RAM

The laptop screen is 4k, and the ACER is 2560x1440

I have tried connecting the monitor through USB-C, and HDMI. There is also a Display-Port connector but I haven't tried that. Any thoughts are welcome. Thanks!

That sounds frustrating!

What version of AE are you running? And I mean the full version number - not "CC 2017" but more like, "14.1.0.x"

Hi Szalam, I'm running version 14.1.0.57

Frustrating.

Try unchecking (or, if it's already unchecked, try checking) the "Hardware accelerate...panels" option.
