Questions to Ask…
1) What’s the Video Wall going to be used for? Lobby signage,
NOC, Presentation System, Rental Unit
2) One large image (across the entire video wall) or multiple sources
(one per screen)?
3) What sources will you be using? PC, Sat or CATV, BluRay DVD?
4) Will there be a control system (AMX, Crestron, PC controller)?
5) Who will be using or managing the video wall after it is installed?
6) If you’re intending to wall mount the video wall, is the existing
wall structurally sound? Are you willing to add or reinforce the
existing wall structure?
7) Do you currently have electric outlets at the location, or can you
have outlets added?
8) LCD monitors come with different bezel widths, which one looks
best for the budget you have? (See next slide for comparison)

Display Wall Color Calibration (part # KT-46UN-CC)
•
•
•
Displays can be easily calibrated for color & brightness uniformity across the video wall.
Highly recommend using digital inputs.
Analog inputs (VGA, RGBVH,etc) show signal noise degradation . This will make it more difficult to calibrate for uniformity.

Video Wall Mounts
Unistrut might be cheap…Installation Labor is Expensive!
Unistrut is relatively inexpensive to use as a wall mount.
However, it takes 4 technicians to service this video wall.
Two people in the front on a lift, and two in the back with socket
wrenches.
