Your display wall needs 4K, but the board in your matrix tops out at 1080p. The VM7814 fixes that. Four HDMI inputs handling 4K2K@60 (4:2:0) plus every HDTV resolution below it. EDID Expert sorts the handshake so each screen wakes up at the right spec — no more guessing which EDID to hardcode. Cable Quality Tester flags a dodgy cable run before it becomes a flickering display in the boardroom. Stereo audio embedding keeps your AV chain clean. Drop it into your VM1600A or VM3200, mix with any other I/O boards you've already got, and you're running 4K without ripping out the whole install
