I find myself with a problem with AppleTv 4th.
My setup is like the picture below but i use ws2812b led.
All my sources go in a AV receiver and then enter the hdmi switch, so I can use more sources and get the most out of my audio system.
If I turn on AppleTv with both hdmi cables coming out of the switch connected, the LEDs work but I have no screen image, but if before switching on the appleTv I unplug the hdmi cable that goes to the hdmi2av I have no problem seeing the Image, so my temporary solution is to disconnect the hdmi cable, turn on teh AppleTv and reconnect the cable to the hdmi2av, so everything works as it should, the fact is that it only happens with AppleTv, all other sources (xbox one and computers) do not have this problem.
Since my tv is only 720p I tried to change the AppletTv output from Auto to 720p 60 thinking it could negotiate the resolution with the hdmi2av before that of the tv and therefore not allow the view on tv but things are not changed.
Has anyone already had a similar problem or maybe the same thing and could you help me find a faster and more elegant solution than having to unplug the hdmi cable?
I begin to suspect that the hdmi switch might be the cause or maybe the hdmi2av though strange thing that with the other sources the problem does not occur
