Video walls are an eye-catching way to show off video material. They work well in lobby and workplace entrance settings. Additionally, they can be especially helpful in conference halls, theatres, museums, and even schools. Building a video wall largely depends on its purpose and what you want it to be able to achieve. This post will cover several ways a video wall can be built and set up.
You will need panels, a video processor, video wall software, supporting structures, wiring data and power, and cooling systems to build a video wall. A video wall must be built according to the required specifications, such as area size, pitch size, brightness, resolution, vertical frequency, response time, 24/7 operation, etc.
Light-emitting diodes are placed as pixels on a video display panel to make up an LED display. The space between each LED pixel distinguishes various types of LED panel displays.
A pixel pitch is a centre-to-centre separation between each diode in millimetres. The display’s resolution increases as the gap closes. The grade for pixel pitch used to source LED display panels is P# (where # stands for the pixel pitch distance).
The lower the “P,” the greater the resolution of the display and the higher the LED density; for instance, “P2 LED Display Panel” denotes a pixel pitch of 2mm.
Large installations like video walls, electronic billboard signs, and outdoor applications are where LED displays are most frequently employed.
A step-by-step guide to set up a video wall
STEP 1: Installation Site
Where will your LED display video wall be located?
It would be best to gauge the opening’s widths, heights, and depths. You must consider how you will attach the Video Wall’s framing to the newly built or existing structure.
The LED display package indicated later in the equipment recommendations might also come with the LED Panel mounting frame. You will have more time to develop and organise a structure to fabricate if you do that.
The frame dimensions can be computed from the LED Display Wall dimensions specified in the following step.
Step 2:
Calculate the Size of the LED Display Wall and Mounting Frame Once you know your general measurements, you can determine the size of your video wall. Alternately, you could inquire about your provider’s display size that will fit your space.
The display ratios determine this (16:9, 4:3, etc.). Choose the dimension with the least value to serve as the base size—is it the width or the height? The lesser value should then be entered into this equation to solve for the matching dimension.
The formula is w = (h/9)*16 for 16:9 screens.
Example: Your opening measures 2000 mm in width and 1080 mm in height.
Your smallest dimension is consequently h:1080mm.
w=(1080/9)*16 = 1920mm for 16:9 screen ratio
Therefore, to attain a 16:9 display ratio that fits into your wall opening, your screen must be a height of 1080mm and a width of 1920mm. Typically, the frame’s dimensions match the overall size of the LED panels.
Design the frame’s placement such that you have room to place your hands underneath it for simple installation and upkeep. When you reach the edges, you will need to cram a shoulder in there, so leave space on the sides.
Make sure to request the provider send you the frame measurements so you can determine the appropriate size for the LED display screen they will provide you.
Step 3:
Do you prefer a front or back service style display screen video wall?
When mounting directly against the opening wall, front service is employed. If you cannot perform maintenance on the video wall from the back, use this kind.
To access the LED cabinet frame and perform maintenance, you must remove the front panels using a special suction tool.
Powerful magnets attach the LED modules to the panel cabinets for a front service LED display screen. Additionally, stronger magnets attach the panel cabinets to the steel frame.
Each LED module is sucked out of place using a suction tool (a modified Dyson vacuum). The LED modules are fully installed, making it much simpler to get within the cabinets.
Back service Installing LED video walls involves mounting the cabinets from the back. However, magnets are still used to attach each individual LED module to the cabinet. This type is useful if you have access to the LED Display frame for maintenance (say, from behind a stage).
STEP 4: Choosing a Pixel Pitch
How close will your audience be standing to see your LED display, and what material will you be playing on it?
Assume that the audience sees your display from very close to the video wall and that you must watch sports in HD or 4K quality.
Then, to conceal the LED pixels from view, use a pixel pitch of P1-3. A reduced pixel pitch improves the audience’s experience at closer range watching. Additionally, you’ll see that the price of a product increases as the pixel pitch decreases.
STEP 5: Powerpoints and Data
Before erecting the framing, you must determine the number of power points and ports the video wall requires and have the electrician install them.
You won’t just connect an HDMI wire to the screen like you would a television. The video wall controller and video processor send information over an Ethernet wire.
Check with your supplier on this. Depending on the video wall management software they employ, they might have various equipment configurations.
The ethernet connections can be extended to the video wall, and the controller can be placed in a different room. If you choose to do this, I advise setting up a mirror monitor to display what the video wall is showing so you can see what is being played in the other room.
STEP 6: Configuration and Programming
Your LED display video wall will remain blank after turning on all the power and possibly have some static lines. It would be best if you now used the video wall controller software to program the video wall after connecting your computer via USB to the controller.
Before making a purchase, confirm this with the supplier. Alternatively, look for separate software and learn about its capabilities. Now connect all the sources of your media players to the video processor, matrix, or splicer. The controller plays the CPU’s signal to the LED display video wall.
Learn how many different media inputs you plan to use. Your video processor may have no audio output and just one HDMI input.

Installation Guidelines
Here are some helpful pointers to keep in mind when installing your video wall panels. The displays should first be unpacked one at a time. Check each display as you go to ensure it is completely undamaged and intact. As a precaution, we advise filming the procedure.
Move the displays and all your tools safely to the installation area after carefully unpacking everything. Check the width and height of your video wall again, then carefully mount each display to the wall.
It can feel exhilarating and make or break as you prepare to install the screens. You’ll require one or two more hands. So, enlist the aid of your team members.
Set up each display row by row from the bottom left or middle. Finally, check that the wire and loop display panels are connected securely to your preferred video sources, such as IR/RS232, DVI, DP, LAN, or HDMI.
Display Configuration
After the screens are put on the wall, what should you do? The displays need to be set up next.
Where do I begin? Set IP addresses for all your displays. After that, give each panel a label to help you know which one will be deployed.
The calibration of your video wall can then be completed. What does the term calibration mean? We’re talking about how you want to change the following qualities:
Brightness
Volume
Fundamental colour balancing
Brightness and colour are the most important calibration factors for monitors and panels. Therefore, you’ll need to modify the screens’ primary colours and light output. Since factory calibration is the norm for monitors, they should look OK after installation.
Over time, minor adjustments in the brightness and hue will be necessary. This might not be seen on a video wall with a single screen, but it will be clear if screens are placed adjacent.
Your eyes could become overstimulated by even the smallest variations in brightness and hue. The last thing you want is for such inconsistencies to minimise the impact of your wall. In other words, if your video wall is not perfectly calibrated, it will appear out of proportion.
Control and upkeep
Multiple times a year, this calibration will need to be done manually. It’s a costly, time-consuming operation that also necessitates downtime. Real-time calibration and continuous real-time calibration have seen considerable advancements in recent years.
These are definitely worth further investigation for those who want to make sure their video wall looks top-notch at all times. The screen images, colour temperature, and brightness of the images on your video wall will all be automatically calibrated by these matrices or video wall controllers.
They will also keep an eye on how image performance is perceived. You’ll achieve the result you’ve always envisioned in this manner. Colours and loudness on each display were traditionally controlled and calibrated using separate devices.
Conclusion
You now understand how to create a LED display video wall for your home, office, restaurant, or client.
When you’re not sure where to begin, it can be a very overwhelming situation. Hopefully, this tutorial was able to help you digest it in manageable chunks. If you still feel like the installation process is out of your league, contact professionals who will do everything for you.
