As an indoor floor decoration screen, LED dance floor video screen has been widely used as an interactive eye suction artifact, especially in large shopping malls and real estate sales centers. It is often used in order to attract popularity during business or opening. However, when installing, hesitate about the limitation of space, and the control box and control computer may be far away.
At present, HDMI interface is used between the control transmission box and the computer. The HDMI cable provided by the manufacturer is generally only one or two meters long, which can not meet the requirements, so it can be solved by selecting HDMI extension cable. Let’s explain the details of the solution.

DMI specification – advantages and disadvantages parallel
A great advantage of HDMI is that you can simultaneously transmit audio and video signals from the signal source (such as Blu ray player) to the receiver (such as AV Amplifier or TV) through a cable.
However, HDMI itself has its limitations. For example, the occasional “handshake problem” (the signal source, TV and projector need to identify each other in turn to achieve connectivity). In addition, there are several different versions of HDMI, which have different characteristics. Different versions determine what is supported and what is not supported. For a certain HDMI version, different manufacturers will decide whether the equipment provides or does not provide certain functions.
Another problem with HDMI is that it sometimes gets into trouble over long distances. In general, for best results, it is generally recommended that the HDMI connection length be less than 15 feet (about 4.6 meters). However, if HDMI wire is of good quality, it can achieve 30 feet (about 9m) and can also be used normally. In addition, if the quality control of the line itself is well done (although the price is not necessarily very expensive), there are HDMI lines that can achieve 50feet (about 15m) and work normally.
However, the situation is more subtle after such a long time, because you may start to see the “flashing screen” phenomenon on the display device with a high probability. You may also encounter a more serious handshake problem – direct black screen. Of course, if you buy wires from low-quality informal manufacturers, you may still encounter these problems even on short HDMI lines.
So, if you want to extend the HDMI transmission distance from 15 meters to 30 meters or even 90 meters, and even wire your whole house so that devices with HDMI interfaces can be placed anywhere, what should you do?
Wired solution – HDMI transmission through network cable
One way to extend HDMI is through an Ethernet cable. Try special switching equipment to connect HDMI signals to CAT5, 5e, 6 and cat7 network cables of the router in the home or office environment. It can also be used to transmit audio and video signals in the home theater system.
LED floor tile screen is spliced by LED modules one by one, and there are no too many restrictions on the area. When the screen body is small, it can be controlled by a small sending box. If the area is relatively large, it should be controlled by video splicing processor. However, no matter which kind, the connecting line with the computer can be HDMI interface. We can learn from the following characteristics of LED floor tile screen:
LED floor tile screen product features:
1 patented bottom shell mask design, anti-skid and anti glare
2. High protection level, no fear of wine spilling and accidental rain
3. High quality LED lamp beads are adopted, with uniform lighting and wide viewing angle
4 after customizing the interactive scheme, the interaction between people and led tile screen can be realized.
5. High strength bearing capacity, with a load of up to 2 tons per square meter.
6. The installation is convenient and fast. It can take into account the use of indoor and outdoor rental screens to realize multi-purpose of one screen.
