Scienstry 3G Film, 55" Switchable Projection Screen, 16:9 Aspect Ratio

hi this is ten today I want to show you about a new issue I ran into while doing projection at different locations and hopefully my solution can help you recently I had to set up in wrong projection in multiple events in multiple locations which I have no control what is being projected on the screen the PowerPoint files or the video files mix in different aspect ratio 4 by 3 or 16 by 9 are given to me just before the event starts I have no time to convert or change them before the event starts let me show you the problem I usually like to send my computer connection to projectors resolution to projectors native resolution in my case 1024 by 768 here's a problem if the screen is 16 by 9 and I want to maximize the projector image size so if project at sixteen by nine video I will zoom and fit the video to the screen but when I switch to the PowerPoint file which is 4 by 3 as by ratio the
