@eight here at our university we use the Hollyland Mars 4K for Kameras: https://www.hollyland.com/product/mars-4k
They are cheaper than Teradek but they have a delay, they say 60ms on the website but its rather 70ms.

Interesting. My experience here in the UK is that venues are increasingly running everything over ethernet, hard wired into the building. Video, audio and control are plugged into RJ45 or Ethercon patch panels, rather than old school analogue ones. I've not come across anywhere that does wireless HDMI. Frankly, I'd be wary of doing that in a professional setting. 

With the Teredek Bolt you're attaching a pretty expensive bit of kit to each end of the projection chain, and each end has to be powered too.

The alternative is to make the cable management less fragile... What about a solution where your computer outputs to an HDMI to ethernet adaptor, and you connect via etherCon and heavy duty ethernet cable? The cable is robust, and cheap, and ethercon protects the RJ45 connector well. And it's a fraction of the cost of Teredek's equipment. But maybe your multimedia lab is very well endowed with lots of money! Not something which happens here.

Extron make robust and affordable HDMI extenders where you only need to power one end.

If your projectors have HDbaseT inputs, then even better, you only need a device at the computer end. Some HDMI to HDbaseT devices will also transmit LAN information, so you can control the projector via LAN...

Just thinking out loud really... 

Hello Isadora Team,

First, thank you so much for the latest update. Amazing!!! Especially the VST plug-ins.

As a stand-alone, Surge XT allows me to switch patches using MIDI 'Program Change'. Clunky but it works.

However, the Surge XT Actor does not seem to listen to 'Program Change'. Is this true, or am I missing something?

@mark_m Thanks! After a bit of chatgpting, I am also leaning toward Teradek Bolt. My use case is the multimedia lab whereby students move the projectors a lot and we got tired of fragile cable management. Also I noticed lately that theatres, even big venues are slowly moving to wireless hdmi.

@eight

I don't have a practical experience of sending from computer to projector wirelessly, but I do have practical experience of bringing HDMI signals from camera to receivers wirelessly.
I managed to set up four independent channels using Teradek Bolt units over 5Ghz, each sending an independent signal to a switcher with no interference. Apparently more is possible with their newer units which operate also in the 6Ghz range.

Teradek is the industry standard for film-makers. Low lag, and reliable. That's what I'd use in your situation.  Curious to know what you're trying to achieve: do your projectors need to move around the venue? 

@ray

Yes, both files need to be opened by the same version of Isadora. 
Open one izzy file, then use the file/open menu to open the other file.
When opened in the same version of Isadora you should be able to copy and paste scene from one to the other.

@eight

You will need to open your preferences folder, and delete "com.troikatronix.isadora.vst3-plugins.json"
That file holds the list of plugins. Isadora should scan for all VSTs again, and revalidate them. This can be a slow process for users with hundreds of VSTs.

Hi All

Is there a way to combine two different patches?

@eight

Why is it required to do it wirelessly over WiFi? Anything display related in my opinion should be done wired

I am looking to connect 4 projectors using 4 hdmi outputs on one computer streamed over wifi adapters. Are there wireless hdmi transmitters/receivers that will not interfere with each other in one venue?

I would appreciate your sharing a practical experience with such setups.

Thanks.
