I’ll give as much detail as I can, and then ask my questions...
We have recently built and had a media room included in our build. We have a low lying entertainment unit at the front of the room with 2 HDMI jacks included in a wall plate. Approximately 10 metres of HDMI then travels up the wall and to the rear of the room and to the projector. The equipment is:
JVC N7 projector
Denon 6500 receiver
Apple TV 4K
HDMI cable used by the builders is “alogic high speed HDMI with ethernet”
I connected the Apple TV to the receiver, and the receiver to the wall jack. The Apple TV was displayed through the projector, and all seemed OK. However, after I turned everything off, things turned a bit strange.
Now I can’t get a signal from the Apple TV to display on the projector through either the receiver, or directly through the wall jack. The Apple TV itself is working ok, and if I move it to the back of the room and plug it directly into the projector with a short HDMI cable it displays perfectly. My Blu-Ray player displays normally when hooked up through the receiver, or either wall jack so the long HDMI through the wall is OK. The receiver can display its help menus on the screen so the receiver is OK. Of interest, when the Apple TV is plugged into the receiver, the associated channel of the receiver displays “no signal” on the projector.
So, it seems that the Apple TV signal is getting lost somewhere after it plugs into the receiver or the wall jack.
1. Would a better HDMI cable connecting the Apple TV to the receiver and the receiver to the wall jack be enough to fix this? or....
2. Would I be better off replacing the cable between the wall jack and the projector? or
3. Is there something obvious I’m missing?
Any advice welcome!
Thanks for your time.
