I'd appreciate any advice anyone can offer on the best way to connect three large screen TVs to the program output from our ATEM Mini Extreme ISO.
We use the ATEM Mini for live-streaming our church services and we currently display the live stream to the in-person congregation through an old VGA projector at the front and a 55" 4K monitor at the back of the church. We're now replacing the projector with two 75" 4K TV monitors at the front. The cable length to each of the front monitors is about 70 to 80 feet; we're planning to use 100-foot 3G-rated SDI cables. The cable length to the back monitor is about 10 feet.
The options I'm considering are either:
1. ATEM HDMI out to an HDMI 1x2 splitter
HDMI splitter output 1 to the back screen via HDMI cable
HDMI splitter output 2 to a Blackmagic Microconverter HDMI to SDI 3G ("HDMI2SDI-3G")
HDMI2SDI-3G output 1 to left front screen Microconverter SDI to HDMI
HDMI2SDI-3G output 2 to right front screen Microconverter SDI to HDMI
2. ATEM HDMI out to a Blackmagic Microconverter HDMI to SDI 3G ("HDMI2SDI-3G");
HDMI2SDI-3G out 1 to a Microconverter SDI to HDMI ("SDI2HDMI#1") for the back screen
HDMI2SDI-3G out 2 to left front screen Microconverter SDI to HDMI ("SDI2HDMI#2")
SDI2HDMI#1 loop SDI out to the right front screen Microconverter SDI to HDMI ("SDI2HDMI#3")
3. ATEM HDMI out to a Blackmagic Microconverter HDMI to SDI 3G ("HDMI2SDI-3G");
HDMI2SDI-3G out 1 to a Microconverter SDI to HDMI ("SDI2HDMI#1") for the back screen
SDI2HDMI#1 loop SDI out to left front screen Microconverter SDI to HDMI ("SDI2HDMI#2")
SDI2HDMI#2 loop SDI out to the right front screen Microconverter SDI to HDMI ("SDI2HDMI#3")
Concerns:
Option 1. Are there any reliable HDMI splitters that provide a strong enough signal for the HDMI to SDI conversion? I haven't had much success with splitters.
Option 2. Does it make sense to convert to SDI for a few feet and then back to HDMI in order to avoid splitting the HDMI signal up front?
Option 3. The total cable length is 106 feet to the left front screen, and 206 feet to the right front screen is 206 feet after looping through two SDI to HDMI converters. Is the right screen likely to have a poorer image than the left?
Any opinions as to which is the best approach?
Thanks,
Graeme
