Blackmagic Forum

Hi, audio guy here, total video noob. I'm planning a man cave setup. Please let me know if this will work.

x4 Apple TV's
x4 LG TV's
ATEM 1 M/E Production Studio 4K
x4 HDMI splitter (to strip HDCP)
x4 Blackmagic Design Micro Converter HDMI to SDI
x4 Blackmagic Design SDI to HDMI 3G Micro Converter

Apple TV > Splitter (remove HDCP) >HDMI to SDI > ATEM 1 M/E > SDI to HDMI > LG

I want to play 4 games at once with one on the main TV. And then to be able to quickly switch any game and move it to the main TV with it's audio and have what was on the main TV sent to where the current one came from. I'll set up Stream Deck using Companion to program macros to make this happen.

The Apple TV's output show 4K HDR (HER10+) 60 (59.94Hz)

The ATEM 1 M/E specs say:
Ultra HD Video Standards - 2160p23.98, 2160p24, 2160p25, 2160p29.97
HDMI Input Resolutions for Computers
1920 x 1080 59.94Hz,
3840 x 2160 23.98Hz,
3840 x 2160 24Hz,
3840 x 2160 25Hz,
3840 x 2160 29.97Hz.

So will this setup work?
Does the 29.97Hz only apply to the HDMI in port and the SDI inputs will be able to support the 59.94Hz coming out of the Apple TV's?
Is this setup overkill and there's an easier less expensive solution? I see a lot of cheaper boxes but this was the cheapest 4K box I could find.
I'm looking for instant seamless changing and not having to wait for HDMI handshakes with an HDMI switcher.

Thanks in advance for any help.
