I have a very strange problem. In EW7 we only use NDI output for the projector though NDI studio monitor and as source in OBS for the live stream. This all happens on one laptop with EW7, OBS and NDI studio monitor. This works great. Specs of the laptop are:

Laptop Lenovo Legion 5 17ACH6H 82JY
AMD Ryzen7 5800H
Nvidia 3060RTX
16GB RAM
SSD 512 GB & Win10NDI from EW7 --> (a) OBS and (b) NDI Studio monitor for the beamerMS Office 2019

Today i created a second user on the laptop with administrator rights. When I want to show a powerpoint through NDI i get a black screen. Songs, scriptures and movies are fine on NDI but Powepoint stays black... When i switch back to first user Powerpoints through NDI work just fine (same schedule with the same powerpoints).

Somehow there is something different between both users but i can't find it... Do you have any idea where to look?

I have to say, there are many topics over Powerpoint which go black over NDI. I really hope there can be a solution for this.

Tx for your reply. I have a Ryzen7 CPU so my only GPU is the 3060RTX.

The strange thing is that with the first administrator account it works fine. When i switch to the second administrator account it doesn't work... So strange and i can't find the difference. I open the same .eswx schedule with the same powerpoint in it.

I checked the Powerpoint Trouble Shooting log in EW7 and with both users it gave an idsentical log:

Update for future reference:

I removed the second user, rebooted the laptop and added this user again --> Powerpoints over NDI works now also for the second user :-)
