Video Wall Displays

A video wall display is designed to be tiled with identical panels into one image, while a normal commercial screen is designed to be viewed on its own. Video wall panels have a much narrower frame, such as the 3.5 mm bezel-to-bezel gap of the Samsung VMB-U series or 0.88 mm on the LG 55VSH7J-H, compared with a far wider frame on standard signage screens.

They also add tiling features: settings that assign each panel its part of the picture, daisy-chain outputs to pass the signal along, and colour calibration tools to match neighbouring panels.

Bezel-to-bezel is the total width of the black seam where two panels meet, which is the frame of one panel plus the frame of its neighbour. It is the figure to compare between models, because a single-edge bezel figure is roughly half of it.

For example, the LG 55VSH7J-H has a 0.44 mm bezel on each edge and a 0.88 mm bezel-to-bezel seam. The Samsung VH55B-E has a 1.74 mm seam, and the Samsung VM55B-U and LG 55VL5F-A have about 3.5 mm.

There are two ways: daisy chain the panels and let their built-in tiling split the image, or feed the wall from an external video wall processor. The Samsung VMB-U and VHB-E series can daisy chain over DisplayPort 1.2 or HDMI, and the LG 55VSH7J-H has a DisplayPort output and a Tile Mode setting.

Daisy chaining suits one source shown across the whole wall. An external processor is the better choice when the wall must show several sources at the same time, place windows freely or switch between many inputs.

Choose 700 nit for bright spaces such as lobbies, showrooms and malls with daylight, and 500 nit for rooms with controlled lighting such as control rooms and meeting spaces. In this collection, the Samsung VM55B-U and LG 55VL5F-A are 500 nit panels, and the Samsung VH55B-E, Samsung VH55C-R and LG 55VSH7J-H are 700 nit panels.

The brighter panels use more power: the 500 nit Samsung VM55B-U is rated at 220 W and the 700 nit Samsung VH55B-E at 250 W per panel. Video wall panels are indoor products, so neither brightness level makes them suitable for direct sunlight.

Panels are matched by calibration during commissioning, using the manufacturer's tools. The LG 55VSH7J-H has Smart Calibration, which can run automatically at set intervals. Samsung factory-tunes the VHB-E series for uniformity and provides Color Expert Pro Mobile, which adjusts white balance on walls of up to 3 × 3 panels using a phone camera.

Calibrate after installation, once the panels have warmed up, and again whenever a panel is replaced, because a new panel may not match older panels that have been running for some time.

Some can. The LG 55VL5F-A and LG 55VSH7J-H support both portrait and landscape installation, and the 55VSH7J-H has a dedicated portrait on-screen menu. For other models, check the installation manual before designing a portrait wall, because orientation affects ventilation and is not supported by every panel.

The mount must also be rated for portrait use. Portrait walls are common for retail and lobby content, where a tall image fits the space better.

Yes, if the model is rated for it. The Samsung VMB-U and VHB-E series and the LG 55VL5F-A and 55VSH7J-H are rated by their manufacturers for 24/7 operation. Some older models in the collection have different ratings, so check the specification of the exact model before planning continuous use.

For continuous operation, also keep the room within the rated 0 °C to 40 °C range and leave the ventilation space the manual requires, as heat is the main stress on a wall that never switches off.

A video wall needs a dedicated mount that aligns panels precisely and lets each panel come out for service. The 55-inch Samsung VMB-U, Samsung VHB-E, LG 55VL5F-A and LG 55VSH7J-H use a 600 × 400 mm VESA pattern and weigh 18.4 kg to 21.2 kg.

The VSYS VSVW02-46T pop-out mount fits them: it takes 37-inch to 70-inch screens up to 45 kg, sits 68 mm to 215 mm from the wall and is tested to 4 times its rated load.

Replace a panel with the same model where possible, because a different model can have a different bezel width, brightness, colour and depth, and the difference shows in a tiled wall. If the original model is no longer made, choose a replacement with the same diagonal, bezel-to-bezel gap and VESA pattern, then recalibrate the whole wall.

This collection includes some older Samsung and LG models for extending or repairing existing walls. Check the model number on the back of the installed panels before ordering.

A video wall design starts with five facts: the layout and size, such as 3 × 3 panels of 55 inches; the closest viewing distance; the content and how many sources show at once; the daily operating hours; and the lighting and temperature of the room.

With those, the panel model, bezel width, brightness, processor and mount can be chosen together. Add the wall construction and whether there is rear access, since these decide the mount type and how panels will be serviced.
