I have my Powerpoint machine as an input into my vMix 27.0.0.83 via NDI. For some reason, the text is much clearer if I view the NDI source on NDI Monitor on the same computer than it is in my input on vMix. The text is not as sharp in vMix and can't figure out how to improve it. It shows up in my records so it's definitely the input. It doesn't improve either if I add it as a capture card via HDMI instead of NDI.

Thoughts/Suggestions?

vMix 27.0.0.83
Edition: Windows 11 Pro
Processor: AMD RYzen THreadipper PRO 5955WX 16-Cores
Installed RAM: 64GB
NVIDIA GeForce RTX 4080 SUPER
Connected to 4k Monitor

You give a lot of specs, but not the most obvious ones.

1) What resolution is your PowerPoint outputting?

2) What resolution is your vMix production set to?

I believe this has to do with the resolution. The happens the other way around. We had 4k displays in the room which received an NDI signal (1080) and they were looking a bit blured. Once we set the NDI to 4k it was crisp. Same situation happened to signage displays that were 4k with content in 2k.
I would highly recommend to avoid scaling. Or if you can avoid use a proper scaler hardware that does thath job.
