Playback Issues - Audio/Video & Power

[Jerzie]

Whenever streaming with my Roku Express (no matter what channel), it will be fine for a while then the screen gets really zoomed in. My tv settings are good. Have no theme on the home screen. I constantly have to back out of my program and restart it or completely restart my Roku.

I have a similar problem. It is on several units. We have several #Roku #express products and over the past few weeks, this problem has been found on several units. The tv settings are good. The picture gets so big we can only see the top left part of the picture. To correct it, we have to power off and on the device. This is not acceptabl

how do we resolve this problem?
