That .exe file sounds cool, but I'm using (I guess) a more hi-tech method. I found some test patterns online that are .mp4 files. They run for several minutes & you can play them in repeat mode on your video player. I had to re-size & trim some of them to get them to exact 4:3 ratio & remove borders.
