How Do I Connect 9 Video Sources to 8 TVs?
This is a sizing question in disguise, and the honest answer depends on whether all 9 sources need to be available at the same time.
Key takeaways
- An 8×8 matrix has 8 input ports — a 9th source has nowhere to plug in permanently.
- If a source is rarely used, physically swapping it into a spare moment is a workable stopgap.
- If all 9 need to be available at once, the honest fix is sizing up to a 16×16, not squeezing onto 8 ports.
Why this is really a sizing question
An 8×8 matrix switcher has exactly 8 input ports. A 9th permanent source simply does not fit without either dropping one of the existing 9, or moving to a matrix with more inputs. See our full sizing guide for how to count this properly before buying.
If the 9th source is occasional
If one source is rarely needed — a backup camera, an occasional laptop — physically swapping cable into a spare or lower-priority input when needed is a reasonable stopgap on an 8×8 system, as long as someone is available to make that change.
If all 9 genuinely need to stay connected
If every source must be permanently available for instant routing, the honest fix is the MSS1611-S 16×16, which gives 7 spare input ports beyond the current need — solving today’s problem and the next few years of growth in the same purchase.
