ATEM Mini Pro not working with projector

I have a PC running on Windows 10 Pro with two HDMI ports. One port feeds a 27” monitor and the other feeds a Binary B-230 HDMI splitter. The splitter takes that input and sends it to three devices: a projector, a 65” monitor and one input to a Roland V-60HD video switcher. In that configuration I have video on all devices.
When I take the HDMI video that’s feeding the input of the Binary HDMI splitter and connect it to any of the 4 inputs of the ATEM mini pro and connect the mini pro output to the input of the Binary splitter I get video on all devices except the projector. And even when I connect the output of the mini pro directly to the projector I still can not get video on the projector. I’ve checked the video settings of the mini pro, the PC and the projector, resolution and refresh rate and they are all the same but still no video.
Help!!!! What am I missing?

did you try to connect the mini to the projector with a short hdmi cable?

We have similar issues connecting the HDMI output from either Mini's or Extremes to some of our Panasonic projectors. If we are using our 2 M/E Constellations, no issue.

If you put a Decimator or other scaler on the feed to the projector, scaling to exactly what your feeding it, it will most likely display

As a note we also have some Dell 27" monitors that dont like the Mini/Extreme output either

Thanks for the suggestion, the video is sent to the projector via an HDMI to CAT6 system. The projector is about 50 feet from the video source and mounted in the ceiling approximately 18 feet up. I replaced the TX and RX of the HDMI to CAT6 system, but I still cannot get video on the projector. Also note that if I use the Binary HDMI splitter only the video is present on the projector.

Ditch that and use a 20 metre fibre HDMI. It's one lightweight cable, no conversion boxes that need power and it will work. We use them with ATEM Minis and never an issue.

that is probably the only way to do this, cat 6 extender will not work

Can't really say definitively, these switchers do have a history of incompatibility, and the signal flow is valid with the Roland currently. If a 6 foot HDMI direct to the PJ from the Atem doesn't work then the solution could just as likely be the Decimator. Those devices have a history of solving the HDMI problems caused by Blackmagic devices.

Good Luck

I was trying not to run another cable but I might not have any other choice here. I will try using a Decimator first but if that doesn't work then a fibre HDMI will be my next try. Thanks for the info.

I’ve found that from time to time, ATEM switchers (of all types) simply refuse to work with certain HDMI cables. As someone who’s been using this series for many years (since the original Television Studio), I’ve learned not to argue with them. Just give them the best cables you can, and they won’t give you problems.

Every “optical” HDMI cable I’ve used (even the thin ones that aren’t truly optical) worked flawlessly – even at lengths of 100 meters - But they’re fragile and tend to fail quickly, so I don’t recommend them for long-term use.

Any attempt to cut corners – using a cheap cable, inserting a converter, or chaining female-to-female adapters – eventually caused issues.

Yes, signal boosting via a Decimator can work, and Blackmagic’s own converters might help too, but honestly, the best approach is one high-quality cable, end-to-end.
Fewer worries, fewer headaches – and everything just works.

Decimator is safeguard .. Save all problems in my setups ..
