Content Refresh

Am new with Yodeck but I would like to see either faster loading of new/changed content over typical client wifi speeds OR some way to blank the screen while new imagery is loaded. My experience so far (limited I admit) leads me to think my shows are amateurish when I have to look at periods where things are sequentially being blacked out and sequentially replaced.Makes me think of the old days when things like this were really slow. Surely there is a better way in 2018.
