Denon 1910 problems, over zooming image and constantly having audio drop outs

Hi I have a Denon 1910, which I am running a 5m HDMI cable to my Ben W1200 projector

I have a Dune base 3.0 player which I have connected to my receiver. When playing a movie the audio will cut out for lengths of time and the only way I can force it to come back on is pressing the mute button, which seems to refresh the receiver.

I also notice that at random points when my projector is loading a movie it all be like 500% zoomed in and I have to turn it off and on again to restore the picture

Any ideas on what my problem might be?


Thanks !!!

Fixed via disabling scaling and some settings on my Dune player
