HDMI divider? Selector? No more cumbersome cable replacement!
What do you do when you print a single image to multiple monitors (hdmi divider), when you print a single image to a monitor (hdmi selector)? You're not going back and forth from the cable, are you?
HDMI Divider - 1 : N Connection
Divider is a device that takes one input and replicates a signal with multiple outputs.
Because the signals are duplicated and output at the same time, all connected devices output the same content.
It is used in offline stores that display the same screen on many monitors.
Considerations for Purchase
Number of input/output terminals
Depending on the product, the number of output terminals varies from 2 to 8. If the number of terminals increases, the price will increase, right? You can choose according to your situation.
Resolution/Injection Rate
You need to check the support resolution and the injection rate.
Most recently released products support 4K UHD resolution.
Depending on the product, the injection rate varies by 24 Hz / 30 Hz / 60 Hz. A product with a high injection rate would be better.
Power supply
Most products require external power supply. This is because if the cable length is longer, the screen may not come out properly.
Check the external power supply types such as DC 5V adapter and 5-pin USB.
HDCP support status
HDCP encryption protocol is a copyright protection technology about images, which encrypts the path of transmitting and receiving digital signals from video playback devices (TVs, monitors) to prevent content from being copied illegally.
If you use a device that does not support HDCP, the image will not be output.
HDMI Selector - N : 1 Connection
A selector is a device that receives a large number of inputs, but outputs only one input selectively.
Other signals that are not output are blocked and can be easily converted during use. If you want to use all kinds of devices on the same TV, such as a PC, laptop, MHL connection through a mobile phone, and console game console, you can use it without having to worry about wiring.
Considerations for Purchase
Number of Input/Output terminals
The selector has multiple input terminals and one output terminal. You can check the number of terminals according to your video device.
Resolution/Injection Rate
Most modern imaging devices often support up to 4K UHD 60Hz. If my monitor is a 4K UHD monitor, of course I have to purchase the highest injection rate product, and if you are replacing the monitor later, it is recommended to purchase a 4K resolution 60Hz product. There is not much difference in price.
Power supply
Most products require external power supply. This is because if the cable length is longer, the screen may not come out properly.
Check the external power supply types such as DC 5V adapter and 5-pin USB.
Remote control
The HDMI selector is convenient with a remote control. You can use the remote control to operate various video devices without having to press the button on the selector.
HDMI Matrix Switch - N : N Connection
The matrix switch combines the distributor and the selector. It receives signals from multiple devices and distributes them to the required output devices.
It's easy to use when there are many connected devices and the environment is easy to change, but it's a bit expensive.
