How to switch hosts without black screen?

        In modern office and home environments, many people need to switch between multiple computer hosts, and do not want a black screen during the switching process. Then a switcher called seamless switching is needed. The following will introduce how to use this seamless switcher to achieve instant switching between multiple hosts without black screen, and explain the common types of seamless switchers.

Common instantaneous seamless switcher types

        The most common ones are seamless switches that only switch video signal sources, such as HDMI® seamless switcher, DVI seamless switcher, VGA seamless switcher, etc.; then there are KVM seamless switches that support simultaneous switching of keyboard and mouse, such as HDMI® KVM seamless switcher, VGA KVM seamless switcher, etc. Another type is a seamless matrix switcher that supports N-in-N-out, supports custom output screens, picture-in-picture functions, etc. Similarly, there are some seamless matrix switchers that support KVM functions. Generally, some of these seamless matrix switchers that support matrix functions support mouse crossing functions, so that you can see the signals of multiple hosts on the same monitor, and you can also control them in real time when the mouse passes over them.

How to achieve instantaneous switching control between multiple hosts

        First, you need a seamless switcher host that supports N in 1 out. If there are 4 computer hosts, then choose 4 in 1 out. If there are 8 computer hosts, choose 8 in 1 out. The following will take the 8 in 2 out HDMI® seamless switcher as an example to explain to you. The equipment required is as follows: 8 hosts with HDMI® interfaces (can be computer hosts, PS3/4, Switch, monitoring hosts, etc.), 1 HDMI® seamless switcher 8 in 2 out eKL-812HA, 1 or 2 HDMI® interface monitors or projectors, and several HDMI® cables. The specific connection and use methods are as follows:

        If you need to use a keyboard and mouse to control the computer, the seamless switcher needs to support the KVM function. The following will take the 8-input 4-output HDMI® KVM seamless switch as an example to explain to you. The equipment needed is as follows: 8 hosts with HDMI® and USB interfaces (desktop hosts, laptops, etc.), 1 HDMI® KVM seamless switch 8-input 4-output eKL-814HKW, 2 or 4 HDMI® interface monitors or projectors (2 of which have the same signal, not 4 monitors showing different images), and several HDMI® cables.

        It should be noted that this HDMI® KVM seamless switch supports dual HDMI® input and output, so that when in use, the main screen and the secondary screen will switch at the same time. The HDMI® A input interface of the seamless switch is connected to the HDMI® output A of the computer host, and the HDMI® input B interface of the seamless switch is connected to the HDMI® B output interface of the computer host. The specific connection is as follows:

         Connect according to the above method. When using, you only need to use infrared remote control, device panel buttons, keyboard hot keys, RS-232 protocol and other methods to easily switch between multiple hosts.
