Ok I am a returning dish customer had last in 2010. What a difference in equipment 9 years makes.. now for the questions. I have a hopper and 4 Joey 3 receivers. All brand spanking new equipment. I have 2 rooms next to each other kitchen and living room. Living room is the hopper 1 Joey in the kitchen.. they are not synced up ther is about a second plus delay on the Joey it is pretty annoying if they are on the same station. The system is all hard wired. No WiFi between them. Question 2 when the receivers are turned off the green power button stays on...... it is in som kind of standby mode Or what? 4k. I ha e a brand spankin* new Samsung tv that is 4K..is there such a thing as a 4K hdmi cable to improve picture quality.. I doubt there is a lot broadcast i. 4 k right now... lastly outa antenna right into the back of the hopper and it will merge local tv into the guide so I can drop the locals on my bill... right now my new dish bill is $61.00 less then what direct hiked my bill up to... like that a lot.... thank you in advance,
