Hey,

This one is a weird problem, okay so i have JVC LT-48UE76 4k TV and Xiaomi mi box 4k.
The problem is that everytime i connect the mi box to the tv and try to turn it on i get "No Signal" at the HDMI channel, I am on the right HDMI channel, I tried chaning HDMI cable and port, i have PS4 that works perfectly on the TV and the Xiaomi box work perfect on other TV that I got so I am a bit confused.
The weird thing is that the Xiaomi box will work if i put the TV on the correct HDMI channel and then take the power cable of the Xiaomi box off and connect the power cable again.
After I mange to make it work if i put the Xiaomi box on sleep mode, I can't get it up again because I am getting "No Signal" from the hdmi channel

So I don't know what is the problem here if its the Box or the TV, the Box works perfectly on other TV and the TV works perfectly without other things like PS4 and Cables.

Any suggestion how to solve this weird problem?


Thanks.

For 4K the HDMI input has to be HDMI 2.0 and HDCP 2.2. If there is only one it would be marked. The box should output 1080p if connected to an older HDMI input.
HDMI can be very tricky. The combination of your box - HDMI cable - TV all have to meet HDMI standards to work correctly. If one of these is off then the other two may or may not be able to compensate for it. That's why a combination may work for one TV and not another.
HDMI 2.1 when it arrives is supposed to be more forgiving of equipment that doesn't meet the HDMI standard.

Wait, on my JVC TV i have 3 HDMI ports and u want to tell me that only one of them is 4k? how can i know which one is the 4k one?
Seems like enabling CEC helped here a bit, still makes the same problem from time to time but I think the CEC helped.
