I have a Hopper 3 and Samsung 4K tv, when I do pip mode all pip modes work fine except multi view, I can see 4 different channels but it flashes between multi view and black screen all the time only on multi view, my software is up to date on both my tv and receiver ive even unplugged both tv and receiver to restart, I contacted dish and they are submitting to engineers to follow up , I don’t believe it’s an issue with my tv , but anyone ever have this issue?
