Control Rooms & Command Centers

Choose the narrowest seam the budget allows when operators read small text, maps or spreadsheets. The LG 55VSH7J-H has a 0.88 mm bezel-to-bezel seam, made of a 0.44 mm bezel on each panel edge.

Walls that mainly show video and large graphics viewed from further away can use a wider seam, such as the 3.5 mm of the LG 55VL5F-A. Compare models by the bezel-to-bezel figure, because a single-edge figure is about half of it.

Yes, if the manufacturer rates the model for 24/7 operation. The LG 55VSH7J-H, LG 55VL5F-A and Samsung QM85C are rated for 24/7 use and for an operating temperature of 0 °C to 40 °C.

Continuous operation adds heat, so keep the room's air conditioning sized for the whole wall and leave the ventilation space the installation manual requires. Older or non-rated models should not be used for round-the-clock walls.

Add up the rated power of every panel. The LG 55VSH7J-H uses 210 W typical and 250 W maximum, so a 3 × 3 wall of nine panels draws about 1.9 kW typical, nearly all of which becomes heat in the room.

A single Samsung QM85C is rated at 330 W. Give the wall dedicated circuits, and size the air conditioning for the displays plus the operators and their workstations.

Usually yes. Built-in tiling, such as the DisplayPort daisy chain and Tile Mode of the LG 55VSH7J-H, shows one source stretched across the wall. A control room normally needs many camera feeds, maps and dashboards on screen at once, in layouts operators can change.

An external video wall processor takes those sources and places them as windows anywhere on the wall. Choose it by the number and type of inputs and the layouts the operators need.

Choose panels with a matte, non-glare surface and plan the lighting with the wall. The LG 55VSH7J-H has a non-glare panel with 28% haze, and the Samsung QM85C has a non-glare panel with 25% haze.

Keep downlights and windows from facing the screen, and use dimmable, indirect lighting in front of the wall. Reflections hide detail on dark map backgrounds and camera feeds, so test the lighting at night as well as by day.

A room that shows a few dashboards to a small team can use one large 4K screen, which has no seams and costs less to install. The Samsung QM85C is an 85-inch 3840 × 2160 screen rated for 24/7 operation with 500 nit typical brightness.

Choose a video wall when the room needs a larger image than one screen, or many sources at once, such as a 3 × 3 wall of 55-inch panels.

Use pop-out video wall mounts that let one panel come out from the front while its neighbours stay in place, or leave a rear service corridor behind the wall. The VSYS VSVW02-46T is a pop-out mount designed for tiled walls.

Remote monitoring helps find a fault early: the LG 55VSH7J-H can be controlled, monitored and updated over a LAN daisy chain. Keep a spare panel of the same model, and recalibrate after a replacement.

Yes, if the new panel matches the old ones. Use the same model where possible, because a different model can differ in bezel, brightness, colour and depth, and the difference shows in a tiled wall.

This page includes older LG 49-inch models, the 49VL5F-A and 49VL5G, for extending or repairing existing walls. Check the model number on the back of the installed panels before ordering, then recalibrate the whole wall.

The 55-inch LG 55VSH7J-H weighs 18.4 kg and the LG 55VL5F-A 20.3 kg per panel. Both use a 600 × 400 mm VESA pattern. The 85-inch Samsung QM85C single screen weighs 41.9 kg and also uses 600 × 400 mm VESA.

Add the weight of the mounts and check that the wall or floor can carry the whole array. Many control room walls use a floor-supported frame for this reason.

Start with six facts: the number of operators and their distance from the wall, the sources and how many show at once, the smallest text that must be read, the daily operating hours, the room lighting, and the wall construction and service access.

These decide the panel model and seam width, the wall layout such as 3 × 3, the processor, the mounts and the power and cooling the room needs.
