HDMI Signal to 3 different configurations HELP PLEASE!

I want to connect my Oppo 4k Bluray player, 4K Apple TV, PS4 & PS3 to 3 rooms all having different display resolution and audio configurations

1. Theatre - Sony 4K SDR Projector , Integra AVR with Dolby Atmos

2. Lounge - Sony 4K HDR & DV TV with TV Stereo sound

3. Bedroom - Sony 1080 SDR TV with TV Stereo sound

What is the best way to do this?

hdmi matrix with edid? I know that can scale down 4k to 1080 but what about the audio 7.1 to 2.0?

hdmi splitter with automatic edid?

hdmi splitter into HDMI DR ?

Am I on the right track or totally off ?

Thanks for your help and suggestions!

any good 4 x 4 hdmi matrix should do it. but it aint gonna be cheap, if you are looking for proper scaling and reliability

I just got a Lindy hdmi switcher and that has edid and it works well but I am not sure if they do a 4x4 with edid on it, do your research but they are a good brand imho.

Be aware that these things don't 'scale' 4K. EDID tells the cable box what resolution to use and then the source will internally change the output resolution to what is accepted at the display.

Devices are, more and more, becoming friendly with changing their resolution on the fly and adjusting to EDID requests, but it's not a guarantee of reliability by any means.

The biggest issue is that 1080p "I don't support nothing!" television. Any 4K sources must not only scale down, but if they have authenticated HDCP 2.2 and that TV only supports HDCP 1.4, then it will need to reauthenticate, if it can, at the lower copyright mode.

I tend to live in a 1080p world in my home, expect my projector which has dedicated 4K sources. It is the only way I've been able to get things to work right.

Oh, and I'm using a $10,000 16x16 Crestron matrix switch. So, it's not an easy task to get done what you are asking for.
