What's the projector?  Is it only 1080?

I'm far from an expert in commercial but for a conference room you really need a system that can handle many different resolutions and manage EDID.  I recently used some of the ConferX products from AVPro and have no complaints from anyone.  The sources are a mix of whatever BYOD shows up with HDMI and USB-C.

Actually the main reason for using this product is the conduit to the table was ran to the rack room so this allowed me to use the HDBT in and then the HDBT out rather than a typical HDBT kit which would have had keystone jumpers halfway through the run (which was probably around 200').

You could replace the AVR with the CX62 and external amp (hopefully the room isn't actually wired for surround sound)
