PowerPoint

[jkerry211]

We currently use PPT in a number of our broadcast. The speaker would like to have PPT in presenter mode on his laptop. But when I bring it up via NDI with our TC1 it show the presenter mode and not the full screen version.

How can I get the full screen of the PPT and not the presenter mode to show on Tricaster.

It sounds like you are using Screen Capture on the laptop to capture the PowerPoint. Screen Capture will only capture the displays it sees on the computer. To be able to use PPT Presenter Mode on the laptop, it would need to push the presentation to an external display. I believe one solution would be to use a Dummy Display Adapter (Headless/Ghost Display adapter) to make the laptop think it has a second display connected, then both PowerPoint and Screen Capture should see two displays and you can use the second display to show the PPT full screen.

Will give it a look.

Thanks

It's definitely not picking up the extended mode. I do events like this a lot. I have the magewell HDMi to NDI converter, so I just take the HDMI out of the computer, and send it directly to the TC. The computer sees the converter as a second monitor for extended mode.

@DStoneburner,
are you sure a Dummy Display Adapter (like NNolte mentioned above) will not do the same job for PPT?

Have not tried yet with PPT on a Laptop, but these litte ´tools´ work great e.g. on my TC2E for remote operation (each ´active´ GPU port then available as NDI stream) to get e.g. TC User Interface screen into NDI Studio Monitor on a Laptop, and have NDI KVM enabled on both ends for remote operations.

I have not tested this, but here is a software based solution that creates a virtual display that would conceivably do the same thing as the dummy display adapter: https://github.com/itsmikethetech/Virtual-Display-Driver

It would be neat if NDI could build something like that into the Screen Capture tool.

Display Dummys or Display Extensions (like Thunderbolt/USB-Hubs with HDMI/DP-Ports) usually do activate those internal (virtual) drivers as I use both ways in a studio: 4 Laptops for PPTs, all with Dummys or Hubs. All of them show both graphic card ports in the TC1 to select from.

If you combine this with the Studio Monitor and KVM activated, you can operate and see the same presentation (no matter if "full screen mode" or "notes view") on each Laptop.

Switching the Presenters Mode on a Laptop, it flips the Presentation Display and Representers Notes.

For us, we now use ZowieBox. These box encode/decode hdmi signal to NDI. https://zowietek.com/product/4k-video-streaming-encoder-decoder/
No app to install and very less expensive.
