I'm using an beamer with 1024/768 resolution. The pictures I make for PtoE are Jpegs with also a resolution of 1024/768. The files I use while projecting are exe files, as I suppose most of you will do. Can anyone tell me what will happen if I upgrade to a 1400 beamer, or for that matter, a 1900 HD beamer? Can I use the same exe files or do I have to make all new exe files? Or, is it only a matter for my Ati Radeon card. Thanks... Henri.
