An LCD (liquid crystal display) screen is an electronic flat panel display that uses liquid crystal glass and transparent electrodes to block or allow light to pass through RGB pixels to display the medium.
In the world of digital signage, we usually use LCD in LFD (Large Format Display), tiled display/multi-screen TV/spliced display video wall, which is a video wall composed of multiple TVs, which can form one Watch the screen.
LCD/TV displays are cheaper than other digital display types, have slower refresh rates and are thicker. However, you can still get good quality resolution from it.
Observe where the LCD video wall monitor will be installed. Get a measure of the width, height, and depth of your open space. In addition, please pay attention to how to install the mounting frame. Do you install it on concrete? On the steel frame? Is it hanging from the ceiling? Standing on the floor? Can it be moved?
When using it, please consider where you can install the power supply, and how to run the data points to the location where you want to control the LCD Display video wall. If you want to place all control equipment in another room, you may also have to plug HDMI into the Ethernet extender.
Next, you need to plan the configuration of multiple LCD screen displays. You can have equal or unequal rows and columns.
The easiest and cheapest way is to use the equal sign configuration. I suggest beginners to use 2x2 or 3x3. In this way, you can purchase cheap video controllers that are easier to install and easier to maintain. The screen resolution can be configured with less effort.
After knowing the required display configuration, you need to find out the size of the LCD screen installed in that configuration to fit your opening. Purchase a series of potentially usable LCD screen monitors or TVs and obtain their overall dimensions. When looking at the specifications, get the location of the mounting screws (you need to know this later, usually using the VESA standard).
Make sure that the overall size of the complete LCD video wall you calculated has a space gap around the entire periphery. Many TV stands are mounted on the frame by hanging them on hooks, so the gap in the video wall should allow this movement. You can still find installation kits with push and eject, flip up and pull out functions.
Now you know the difficult way to plan the size and LCD screen size. A simpler method is to buy the complete package of the 2x2 matrix LCD video wall from a supplier and provide them with an opening size of about 100mm. They will recommend the screen size for you and include any installation equipment needed.
Obtain resources from your LCD video wall controller and check if it has the same output as the number of monitors you want to use. Make sure it can control the resolution you want to display. It is also worth mentioning that some LCD screens have a built-in video wall function and do not require you to purchase an additional controller.
When designing an LCD video wall frame, you need to consider how to install/disassemble the TV and how to install the frame to the wall/floor/ceiling. You will also consider the total weight of the equipment, the bending of the frame due to weight, the cable routing, and the space behind the TV for wiring and fit your hand when you need to enter.
If the frame is in a groove on the wall, leave some space around the frame. If you want to tighten for aesthetic reasons, you need to find a mounting solution that allows this, such as a pop-up or pull-out mounting bracket.
Commercial frames usually use steel RHS (hollow rectangular cross-section) or C-shaped studs and channels to increase strength and sometimes aesthetics. However, for smaller budget projects, you can use timber frames.
The power point should be installed after the planning phase and before the frame installation. You will need to consider using Powerpoint to power each TV/LCD screen and plan to install a controller in that area. The next important thing is the cable that connects the media input to the screen. Suppose you plan to place the controller in another room. In this case, you will need to run HDMI to Cat5/6 extenders and convert them back to HDMI connections to connect to the device (included in the package at the time of purchase).
Every LCD monitor needs an HDMI to cat5/6 converter, which also needs its own PowerPoint source. You use HDMI to CAT extender because cat5/6 cables are much cheaper than HDMI cables. For longer extensions, Cat cables are more efficient and flexible to install.
After the planning phase, you can order equipment. I have collected some products for you and listed below the products you can buy directly from the link. These recommended products will provide you with the best value for money.
The main components required for a Multi LCD screen video wall display are:
2. LCD monitor screen/LCD TV
3. LCD TV wall matrix controller
First ask an electrician to install the power supply and data, and then install the frame into the open space. For structures with independent parts, please use a spirit level to keep your face flush and level before installing the TV.
Install one TV at a time and plug in the HDMI cable and power supply so that they are flush with the nearby TV. When extending HDMI to another room, plug the HDMI into the Cat extender and place them in a strong enough position without the cable dropping.
After all TVs are turned on, you can plug the other end of the cable into the output of the LCD matrix controller, and then also plug in the media input.
After everything is plugged in, test all equipment and pat the back. If it doesn't work, please take everything apart and start again. Just kidding, you just need to think logically from the symptoms and use Facebook groups and forums to ask questions. Or, you can also contact me to ask any questions I have.
Multiple LCD video walls may be a cheap way! Viewers combine multiple TV monitors to create a large viewing screen. By following the 8 detailed steps written in this article, you can understand how easy it is to make your own. Whether for business purposes or just to impress your tenants.
