Avoid the hassle of frequently changing cables — our home theaters may have more than one HDMI signal source, but not all monitors have multiple HDMI interfaces. Previously this problem could only be solved by unplugging and inserting the same HDMI cable on different machines, but now this HDMI switch can optimize this process well.2 In 1 Out — Most homes or offices these days basically have multiple high-definition devices, but often there is only one screen. We can only unplug the HDMI cable from one device, and then put that HDMI cable into another device to import different signal sources alternately. But with this switcher, you only need to press a button to change the signal source.8K Support — As we know, 8K is becoming more and more popular. Its 7680 x 4320 resolution rate and 8K @ 60Hz, 4K @ 120Hz refresh rate make the performance of movies or games even better. If you have 8K equipment and resources, this switch can help you transfer 8K data without any obstacle, giving you the enjoyment of highest definition. switchEasy to use — there are also two indicator lights on the HDMI splitter to indicate which channel is currently working. You can easily tell which signal source is being used. Then you only have to press the middle "SELECT" button to switch between the different signal sources with just one button.Compatible with most devices — HDTVs, game consoles, projectors, monitors, laptops, Blu-ray players, DVDs, TV boxes, and other devices that include an HDMI output. You can connect these equipments freely with this switch and find the combination which allows you to enjoy work or entertainment better.
