New to Dish, very satisfied so far on H3 picture quality depending which channel your watching, and operation of H3. I am coming from Directv . But I am new to the Joeys, did not have a Genie. Does anybody know if the Joeys actually process the video signal or are they just a relay station so to speak. Picture quality is lacking in my opinion from my second room Joey. Was getting better Directv picture using a hdmi switch. Would a 4k Joey produce a better picture, could not find any info on search. I have a feeling they don't process video but maybe someone can enlighten me.
