Our company is looking to update/upgrade our training facilities. We currently have 3 rooms side by side that can be opened up to have 1 small 1 big or 1 giant room. Call them rooms ABC. Each room has identical projectors installed with a capabilities to project each room individually or feed from room B to either A or C or both. We currently have VGA cables in A and C that run from B and just hang on the wall next to the vga feed that goes to each of their projectors to manually swap when needing to mirror room B's image. We utilize audio out of the pc into an amp in each room. Room B also has an cable for audio to each of the other rooms and we mirror audio by changing the input on the amp in the room.

Our plan is to upgrade the projectors to be brighter, replace VGA with HDMI and make the whole switching process be much simpler. Our plan is a 4x4 HDMI matrix that also captures audio from the desired input and can pipe that to the amp in Room B and then a 4x1 or 4x2 matrix in the other 2 rooms with 1 input Desktop, 1 input laptop, 1 input one of the other rooms, and the last input would be the other room. We then would mount a Kramer wall plate control that would allow us to control the amp, projector, and matrix via RS232 or IR so the users turns the projector on with one button, selects the input on the matrix with another button and can control the volume of the amp with 2 more. Power to the amp or source on the amp if enough buttons are available.

Anybody ever setup a scheme like this and if so, what hardware was used? OR Has anyone else implemented a project like this another way? Our biggest pain points right now is that every week someone doesn't remember they have to swap cables at the wall to get the image from their room or they don't know how to get the other rooms to show B.

Yes, this is why commercial A/V companies exist - it's what they do.

Crestron has 8x8 HDMI matrix switchers and larger which can deal with this nearly automatically. Tie in partition sensors to know when rooms are opened or closed, and give you the ability to fully matrix the setup - that is, show something the same, OR DIFFERENT on every screen and choose your audio for the space separately.

It can incorporate audio conferencing, web conferencing, along with computers, cable TV, media players, wireless connectivity devices, etc. as you want.

Touchpanel control in each room can make picking and routing a source a breeze.

In a large setup like this, you must incorporate HDBaseT for piping HDMI signals everywhere, which Crestron handles with ease, as does a long line of other manufacturers.

Keep in mind, you are talking about making a more complex system, so if you want it to be easier to use than your current relatively 'simple' setup, then you must spend the money to hire someone who is a professional at doing just that.

In my 15 years in the business, one of my pet peeves is people who have absolutely zero experience telling me how I should do my job. So, take the advice of whatever company comes in, and understand that budget is everything.

If you feel like you just want to do it yourself, consider whether you would do the electrical, or plumbing yourself. This isn't something simple. A 3-way divisible room takes 40+ hours to program properly depending on the complexity and shared resources. A 'basic' 3-way divisible with just PCs may be done with 24 hours of programming and several technician days for installation.
