HDMI is the current mainstream video interface. Everyone must have seen or come into contact with HDMI distributors, switchers, network cable extenders, conversion cables and other dazzling and similar-looking HDMI peripheral equipment in conference projects, monitoring projects and daily life .
What exactly are they used for? What application scenarios is it suitable for and how to choose?
1.HDMI splitter
An HDMI splitter is a multi-port output device that can distribute input HDMI signals into multiple consistent and synchronous HDMI signal outputs.
It is often used in training, monitoring and command centers, retail, store displays, remote video conferencing and other occasions where multiple display devices are often required to display the same picture. There are usually HDMI splitters with 1 in and 4 out, 1 in and 8 out, etc.
Supports 4K*2K/30Hz resolution, built-in dual smart chips, plug and play, smooth viewing, and undistorted transmission; it adopts a painted shell and gold-plated interface, which is anti-interference and not easy to rust, enhances the stability of signal transmission, and ensures transmission The picture quality is not compromised; it is equipped with a 5V1A power supply to provide strong power.
2.HDMI switcher
An HDMI switch transmits one or more HDMI signals to one or more display devices respectively. For example, if two computer hosts share a monitor, a matrix switcher can arbitrarily switch the content on the two computer hosts to the same or multiple display devices. on a monitor.
Switchers have been widely use in some performances, high-definition video conferencing systems, shopping mall advertising, medical systems, etc. where video signal sources need to be frequently switch. Manual signal switching not only takes time, but is also extremely error-prone, leading to serious on-site accidents.
With the increasing number of home entertainment devices, more and more video terminals need to be connect to TVs, such as Android boxes, PS4, computers, etc. However, TVs often only have one or two HDMI interfaces, facing numerous peripheral inputs. Equipment, the HDMI interface on the TV will become stretched, and it is really troublesome to plug it in and out.
The HDMI switch perfectly solves the problem of too many input devices and lack of TV HDMI interfaces in family life. It is compatible with various mainstream systems such as Windows, iOS, and Android. No need to install drivers, plug and play; supports 4K/60Hz ultra-high resolution ; Equipped with infrared remote control/button dual selection, smooth switching with one button.
3. THE HDMI cable extender
HDMI network cable extender is a device use to extend signals. It consists of a transmitter and a receiver. Cat6/Cat6A network cable can be use to connect and extend the middle to ensure long-distance signal transmission without attenuation. In terms of cost, it is more expensive than HDMI cables. Low, it is an economical choice for long-distance transmission. And the fault tolerance cost is low. If a single accessory in the entire transmission line is damage, it can be update and replace.
Currently, some merchants offer HDMI network cable extenders that can extend a single network cable up to 150 meters , truly breaking the distance limit and allowing you to enjoy 1920*1080 high-definition picture quality. Generally speaking, Akihabara HDMI cable extenders can be use for high-definition audio and video equipment that requires long-distance transmission.
4.HDMI high-definition conversion cable
When your input device and output have both a DVI interface and an HDMI interface. That directly using an HDMI/DVI cable connection is the best. But if there is only an HDMI interface on one end and a DVI interface on the other end. You can use the conversion cables of the two interfaces to connect between the devices.
Such as HDMI to DVI high-definition cable , dual-line conversion, one-line multi-purpose, supports 1080P high-definition picture quality, making the picture lifelike.
Of course, there are other conversion cables, such as HDMI to VGA, Type-C to HDMI, etc. To get rid of the limitations of the interface.
In daily life, it has become normal to use multiple video devices at the same time. Switch between them, use them over long distances, or need to switch between them. In order to solve these problems, HDMI-related peripheral equipment will definitely be often involve. Everyone just needs to understand their differences and use them according to their actual needs. Just choose the corresponding equipment!
