Premiere pro turns my second monitor off and on

Hello everyone!

 

I just got a new PC, installed premiere and the other programs I use (photoshop and AE). Now when I use Premiere Pro, my second monitor keeps turning off and on for a second whenever I change screens to another program

 

This happens JUST when Premiere Pro is on, didnt happen with Photoshop and AE. Funny thing is, when Premiere Pro is on, even taking my headset off and on turned the second monitor off and on.

 

Anyone had a similar problem?

 

My new PC have a RTX 3080, main monitor is using a display port and second monitor using HDMI

 

Thanks for any help

Thank you guys for the answers. I found the solution, which is something very odd haha

 

Premiere pro was using my capture card as an audio source (microphone), that's why it was turning my second monitor on and off. It was pretty much turning my capture card on and off every time I tabbed premiere. All I had to do was to change to the correct microphone and it was fixed

There is an un-common fix, which may have worked here also, that is in Preferences -> Audio Hardware -> Default Input set it to: 'No Input'. Give that a try.

This was happening to me last night, I thought my graphics card waa cooked but only happened while I was editing in Premiere and only my second monitor. How odd. I haven't tried your solution and thought this post wouldn't exist when I searched googled haha.

    Try a new video cable.

    You may also have a loose power supply lead or an under powered power supply.


    If NVIDIA graphics, make sure to use the latest Studio Driver from NVIDIA (NOT the Game Driver).

    Taking your headset off? As in physically off your head? That sounds more like a cable is being pulled and one of your cables is losing connection for a brief second. And when you say "change screens" do you mean moving the cursor from one monitor to another or are you clicking in another program to change focus?
