I have two computers, one is a Surface Pro 4 (let's call this "A"), the other a Surface Laptop 2 ("B")

I have set up B in the same way as A as far as possible and the only remaining issue is one with PowerPoint over NDI. I have reviewed all the other cases I can find and none of them gives a satisfactory fix as far as I can tell.

BOTH machines have:

• Easy Worship 7.2.3.0
• OBS 26.1.1
• PowerPoint 2016
• Windows 10 (A has Enterprise, B has Home)

I run Easy Worship on both laptops, both using NDI - PAL 1920 x 1080 25Hz for output, playing the same PowerPoint slide presentation and the same song..

Both machines are on the same LAN, so I can see both NDI streams on both machines.

Here's what happens:

• OBS on A with NDI from A => PowerPoint and Song are fine
• OBS on B with NDI from B => Song is fine, PowerPoint black
• OBS on A with NDI from B => Song is fine, PowerPoint black
• OBS on B with NDI from A => PowerPoint and Song are fine

In short, on both machines, all is well when NDI comes from the Surface Pro but PowerPoint is black when NDI comes from the Surface Laptop.

I could could really do with some help to fix this. I am moving off the Surface Pro because its screen is defective and difficult to work with. It is not an option to keep the Surface Pro.

Thank you

Hey Guys, So i just had the same issue. I work in IT and I was able to resolve this. 

Here is my setup 

   Laptop A Easyworship ----------> Laptop B Obs

So on Laptop A, I unisntalled Office completely. Then i removed Onedrive. You must reboot. 

I when into Graphics and made sure Easyworship is always running in High performance mode. Also my firewalls are down. 

after reboot reinstall office While Easyworship is running. After office installed try using powerpoint over ndi. This is what I did and it has been working. Let me know if it helps out! 

Randy and Dan,

I just did the same fix.  However, because of complications and install, removal and reinstall a couple of times... I forgot to have Easy Worship open while installing the 64 bit version of Office 2019.   But it worked.  I can now use PPT over NDI to OBS!  Thanks for this tip~!  Blessings!
