I recently bought a HISENSE 4K 58" TV (50H78G). I have my Mac Mini hooked up to it, and it works fine, until I turn the tv off. When I turn the TV back on after a few hours or overnight, the Mac Mini no longer is recognized, it says "Weak or No Signal", even though the Mac is on. I have tried replacing HDMI cables and using different HDMI ports on the TV, but the only way I can get the Mac Mini to be recognized is by forcing it to power down and restarting. Anyone know how to fix this?
