An LED video wall makes sense in a conference room when you need a single seamless image larger than the biggest flat panels (roughly 100 inches and up), in a boardroom, divisible room or training space. For most meeting rooms, a 75-98 inch commercial display or two side-by-side displays cost far less and are easier to install. If you go LED, choose pixel pitch by the closest viewing distance, usually 0.9-1.5 mm for meeting rooms.
LED wall vs TV vs projector
| Commercial TV | Direct-view LED wall | Projector | |
|---|---|---|---|
| Size | Up to about 98 in | Any size, built from cabinets | 100 in and up |
| Bezels | None on a single panel | Seamless | Seamless |
| Brightness | Good | Very high, fine in daylight | Weak in bright rooms |
| Install | Simple wall mount | Structural mount, power, often a controller | Ceiling mount and screen |
| Cost | Lowest | Highest | Moderate |
Note: a "LED TV" in a shop is an LCD TV with LED backlighting. A direct-view LED wall is a different technology where the LEDs themselves are the pixels.
Pixel pitch and viewing distance
Pixel pitch is the distance between LED pixels in millimeters. Smaller pitch means a sharper image up close, more pixels, and higher cost. A common industry rule of thumb is that the closest comfortable viewing distance in feet is roughly 8 to 10 times the pitch in millimeters.
| Pixel pitch | Approx. closest viewing distance |
|---|---|
| 0.9 mm | About 8-10 ft (2.5-3 m) |
| 1.2 mm | About 10-12 ft (3-3.7 m) |
| 1.5 mm | About 12-15 ft (3.7-4.6 m) |
| 2.5 mm | About 20-25 ft (6-7.6 m) |
Pitch also sets resolution for a given size. A 1.5 mm wall needs to be quite large before it reaches true 4K. For text-heavy content like spreadsheets, check that the wall's native resolution is enough to read at the back of the room.
Sizing an LED wall
- Start from the farthest seat and pick a height so text is readable (about one-sixth of that distance for general content).
- Use a 16:9 shape so meeting video and content fill the wall without black bars.
- Mount the bottom edge high enough to be seen over the table, and keep the camera at or near eye level.
Camera and audio placement
LED walls are tall and wide, so a camera on top can end up well above eye level. Options:
- Mount the video bar below the wall on a credenza or bracket.
- Use a separate camera at the front, centered under the screen.
- For large rooms, consider a dual-camera bar like the Poly Studio X72, Neat Bar Pro or Logitech Rally Bar 2, or a PTZ setup from best PTZ cameras.
LED cabinets and their power supplies can have cooling fans. Ask for the noise rating and keep microphones away from the wall.
What drives cost
- Pixel pitch (the biggest factor)
- Total area
- Mounting structure and installation labor
- Video processor or controller
- Service access (front-serviceable cabinets cost more but fit flush on the wall)
LED pricing varies widely by manufacturer and changes often. Get a project quote rather than relying on a per-square-foot figure.
