Buggy BP nodes in multiple monitor setup

Hi All

I’ve just spent a day trying to set up Spawn Actor from class nodes in the level blueprint I’m working on. The machine I’m working on has 3 monitors (and 4 gpu’s). The editor was open in the primary monitor and the level bp was open in the second monitor. The Spawn Actor node has been extremely erratic- I was finding it very difficult to select the class- all of the available methods (selecting from the drop down list, selecting the asset first etc) all took repeated attempts to work. However, as soon as i moved the level BP window into the primary monitor, it worked fine.

Thanks!

Hi robbiecooper,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this on my end?
  • Can you post your dxdiag here so I can take a look?
  • Are you using two different GPUs (one for each monitor)?

It does happen in a clean blank first person shooter project. I have the third and the first monitors plugged into the primary GPU. The second monitor is in the second one down. Whats dxdiag?

Heres the dxdiag on pastebin ------------------System Information------------------ Time of this r - Pastebin.com

I reproduced the error just by opening a new blank first person project, opening the level BP in monitor 2 (with the editor open in monitor 1) and creating a spawn actor from class node. Then try clicking on actor input to access dropdown menu.

Hey robbiecooper,

Three things:

  1. What ports(and more specifically, which card) are you plugging your monitors into?
  2. Please update to latest drivers
  3. Can you try unplugging your monitors one at a time (leaving two of them plugged in at all times) and tell me if unplugging any one of them makes a difference?

Updating to the latest drivers fixed it! Thanks!
