Powerpoint Resolution

When I do a screen share and show my Powerpoint in Zoom it is very crisp and high quality, but when I copy the slides as PNG files to create a slide show in OBS those same slides seem fuzzy or at a much lower resolution. This isn't inspiring me to use slide shows in OBS unless I can work around this issue. Any ideas for how to do this?

I'm not a Mac user, so be aware of possible OS level differences
I stream at 1080p, so I got a main 1440p monitor, so I could run a windowed PowerPoint slide show and Window Capture without re-scaling. The default encoding/re-scaling method is targeting a balance of encoding demand and sharpness. I was encouraged to change from the default (bicubic?) to bilinear (I think, from memory 2 years ago) and Lancos (sp?). Anyway - numerous discussion on these at this site (possibly in other OS forums) which may help... basically experiment with the options to get the sharpness you want/need, balanced against your hardware resource capacity.

- [As assumptions are dangerous) - you did confirm the PNGs themselves are sharp, right?

One thing I did is re-export the original slides as JPG files and they may be a bit sharper. I wish I could follow your suggestions but I don't know these settings, where to find them, or what steps to follow.

Perhaps you should look into PowerPoint’s export settings? I’ve done PowerPoint PNGs and imported into OBS as an Image Slide Show and haven’t noticed a quality difference. Also make sure the aspect ratio of the exports matches that of the OBS image slide show source.

That’s all I can think of.

hello; 1) "save as" images all presentaton in powerpoint has its settings 2) why not to ad a source "window capture" with the powerpoint presentation in presentation 1 by 1 mode (see your presentation settings in pp)
