On some channels I get a full screen, some channels or movies I have letter box, and other channels I get the small box in the middle.
Is there a way to ensure all channels always fit to screen with the Roku
anyobody have an answer to this ?
when you go into roku Xfinity stream beta settings > format do you have HD preferred? this will also use the automatic format display settings that some SD channels use to fill your screen. channels without AFD will appear with curtains on left/rigth and 3:4 or nearly 1:1 or if original was in 16:9 the image may appear letterboxed (like a stamp on the screen with curtain all around).
