I have Sky Q box connected to the projector on HDMI 1 and from there via ARC via HDMI 2 to a Denon S217 sound bar.
Every time I start the equipment up, the screen image blinks on and the blanks multiple times without stabilising eventually it reverts to a screen full of digital noise.
If I manually go into settings and select HDMI 2 then select to HDMI 1, the screen image locks in successfully.
Obviously, the system works but startup is not working. How do I make it all lock in first time?
