I believe we are familiar with video walls. They not only come in various types and bring us stunning visual displays, but also serve as decorative elements for spaces.
Currently, the market offers video walls made with LED, LCD, and projection technologies. This article will focus on multi-TV screen LED walls.
What is a TV screen LED wall?
The TV screen LED wall is a customizable background wall created using LED technology. It can be tailored to fit any blank area within a space, forming an attractive and fashionable dynamic background that offers a captivating visual experience.
Unlike regular TVs, The multi-TV screen LED wall is not just something you turn on with a remote control; it requires some assembly and adjustment. Let’s delve into its components.
Components of Multi-TV screen LED wall
The multi-TV screen LED wall consists of two main parts: the display and the media player.
Display
The wall is assembled by piecing together small LED or LCD screens, each like a tile, capable of displaying any content. The screens can be joined together to cover the desired area or length.
LED screens are preferred for video walls due to their energy efficiency, brightness, and wider viewing angles. However, multi-TV screen LED walls are generally more expensive than LCD screen walls, which is why many places still use LCD screen walls.
The multi-TV Screen LED Wall Is Available In a Variety of ResolutionsIn addition, multi-TV screen LED walls have strong scalability and can be arbitrarily composed of 2K (1920*1080), 4K (3840*2160) and 8K (7680*4320) resolutions according to actual project requirements.
Media Player
The media player, also known as a video processor, is used to adjust and control the screen. It connects the PC and the display via HDMI or VGA cables and uses specialized LED control software to adjust and scale the entire image.

Choosing the Right Multi-TV screen LED wall
Ultra HD TV Screen LED WallIf you want to choose and install the multi-TV screen LED wall, it’s crucial to understand the following information before purchasing:
Determine the Size
Although TV screen LED walls can be customized in terms of area and size, you still need to measure the required size in advance. If the purchased LED screen wall exceeds the available space, some LED panels may not be usable.
Determine the Model and Viewing Distance
The price of different multi-TV screen wall models varies and is closely related to the actual viewing distance. For larger spaces where the viewing distance is greater, models like P1.875 and P2 are suitable. For closer viewing distances, models like P1.25 and P1.667 are better.
Using an inappropriate model can significantly affect the overall viewing experience. Therefore, it’s important to provide this information to the sales consultant before purchasing.
Installation Location
If the location for the multi-TV screen wall is not completely flat, but has protrusions or corners, communicate this with the sales consultant in advance to ensure proper installation.
Necessary Auxiliary Equipment
As mentioned, The TV screen LED wall requires a media player and a dedicated computer. For tech-savvy users, a self-purchased computer with manufacturer-provided tutorials can also achieve the same effect.
Is long-term technical support provided?
Many people generally give priority to brands when buying goods. One of the important reasons is that brand owners can provide long-term after-sales support and technology. Therefore, before we plan to buy a product, we first need to determine whether the seller can provide long-term service.
Have you been engaged in the manufacture of TV screens for a long time?
This is also very important. Manufacturers who have been engaged in TV screens for a long time often have more rich experience, enough to solve all the problems you encounter in use, while manufacturers with insufficient experience, on the contrary, not only can not solve your problems, but may also drag the problem for a long time without solving it.
TV Screen LED WallHow should the Multi-TV screen LED wall connect to the computer using HDMI?
When we buy a Multi-TV screen, the next step is to understand how to connect them to the computer. This will make it easier for us to change the content on the screen.
Step 1: Choose the right HDMI interface
Since there are many different models of HDMI, such as HDMI 1.0 and HDMI 2.1. Considering the compatibility issue, it is generally not recommended to choose models that are too old or too new. We can give priority to HDMI 2.1, which has stronger stability.
Step 2: Select the number of HDMIs according to the number of TVscreens
HDMI 2.1 allows you to connect up to 8 displays at a time, so the number of your specific splicing is also very important. If the HDMI splitter you use needs to connect two screens at the same time, but one input port needs to be connected to the source device, then in addition to the HDMI cable, you also need to use it with an HDMI switch.
Another thing to note is that you should measure the distance of each screen in advance, so that you can ensure that the length of the purchased HDMI cable is long enough to connect to each screen.
Step 3: Make sure the settings are correct
Connecting the HDMI splitter to the HDMI access source is only one step, and the other step requires selection on the screen. Generally, there will be options such as HDMI 1 source, HDMI 2 source and PC connection on the display. According to the interface you choose, select the HDMI signal input source correctly.
If you need to allocate multiple displays, be sure to check the signal input source settings of each HDMI to ensure that the picture can be displayed normally.
Step 4: Test and troubleshoot HDMI display problems
When all your steps are completed, congratulations! Now the screen can be displayed normally. If the screen does not display normally, you may need to consider the following issues:
- Is the HDMI cable connected to the screen normally?
- Is the signal input source of the screen selected correctly?
- The screen is damaged.
- The HDMI switch is damaged.
If the above problems occur, please handle them according to the fault situation, or seek help from the TV manufacturer.
Evaluating Multi-TV screen LED wall
Clear Image Quality
A good multi-TV screen LED wall should have bright and clear image quality from any viewing angle. Poor quality walls may distort or blur the image when viewed from different angles.
No Dead Pixels or Bright Spots
Upon assembling the screen wall, there should be no dead pixels or bright spots. If many dead pixels are visible, the product is likely of inferior quality.
Durability
Given the high cost and potential assembly time of several days, durability is crucial. A good multi-TV screen wall should last 7–8 years. If issues arise after several years, individual panels can be replaced.
Reasonable Price
Low-priced products often compromise on quality, but expensive products aren’t necessarily the best. It’s essential to compare several options to find a reasonably priced product.
Conclusion
As LED screen walls become a part of our lives, investing time in comparing and selecting can help us get the best product at the most suitable price.
