We have a 55" smart TV that links directly into the wifi for the stage view. Overall it works well, however, I have modified a couple of files in C:\Program Files (x86)\OpenLP\plugins\remotes\html (see attached). The changes I made basically is to show powerpoint, pdf and images almost full size on the stage view to allow people giving talks etc. to read the text on their slides instead of turning round to look at the main screen. Just thought it may be of use to other people.
One thing I noticed, however, is when you have png images it appears to not show the correct thumbnails ( e.g. http://192.168.1.17:4316/#slide-controller
) - works fine for .jpg etc. just not .png?
