Where do you want to add a logo? You can use a JPG as the previous member mentioned. If you want a PDF you need to load the Adobe reader on the screen. The problem with it though is space. Adobe Reader is big, and I do not use it. What I load onto the monitor, is PPT Viewer, K-Lite Codecs, Adobe Flash and that is it. Word, Excel and Adobe Reader take too much space and I do not use them.
