![]() The plan is to use 2 Magewell HDMI to USB adapters and actually a third one for the presentation laptop, all to the vMix computer (laptop). At present it looks like it defaults to 720p in all cases. My current project is a presentation with 2 camera setup and a computer presentation so, 3 video inputs. I would like to see some control of resolution. It creates an NDI stream that you can access locally, or collect over the network. it's most common when you try to capture a windows vs full-screen. Desktop sharing apps, like vMix Desktop Capture may not be able to intercept the video, so you see black. This can happen when PPT is using hardware accelerated output to stream to the video card. ![]() Once I duplicated the screens laptop / TV, it all worked, but the presenter dind't have his "driving" controls for PPT. vMix is a Software Video Mixer and Switcher that utilises the latest advances in computer hardware to provide live HD video mixing, a task previously only possible on expensive dedicated hardware mixers. On the main screen (laptop) I could see a preview window of PPT with controls and next slide showing. While I could see the previews ( displays and windows ) on my vMix station, when I added the full screen PPT ( showing correctly on TV ) it came black in my vMix INPUTĪgain, as a thumb preview it all looked fine, when adding the full screen PPT as the chosen input, it came as a black screen. PPT was fullscreen on second "monitor" - the TV Presentation Laptop > Extend Display > 1080p TV I used Desktop NDI on my first project but had a bit of an issue with the PPT presentation. Thank you for the suggestions, I'll give that PPT NDI a try.
