Hi, I am using windows 10. I have a four screen set up. I have 3 monitors with a triple monitor wallpaper spanned across, and a fourth screen with a different image. When I change the triple monitor image from wallpaper to video, the button to adjust the size grays out, and the video is too zoomed in. It fits the three screens fine, but it is so in my face it's hard to look at.

How do I keep it on all three screens, but be the same, (don't know what word I need here) Aspect...? Not sure, sorry.

Thanks
