HDMI Switch Bi-directional HDMI Splitter, 4K HDMI Switcher 2 Input 1 Output or 1 Input 2 Output, HDMI Switch Splitter 2 x 1/1 x 2 Supports 4K 3D HD 1080P for Xbox PS4 Roku HDTV

I have two computers sharing one massive Samsung Thunderbolt 3440 x 1440 display, and this switch is perfect. There is no loss of quality on this very wide, high res screen, and it switches between systems at the touch of a button. I have used it for about 2 months in this mode, and it is very handy. One of the systems is a high spec laptop (Thinkpad Ryzen 7), where I run the Thunderbolt as a second screen, through the switch. For the other, it is the primary output. Switching is instant, screen quality is perfect, no distortion or loss of any kind. Highly recommended, very good value. No external power needed, just two HDMI cables in, 1 out to the monitor.

Good value for money and just works. You need to be aware it does not come with any cable (so if you have 2 devices to connect to 1 TV, as I did, you will need an extra HDMI cable). Would have been 5 stars except for the insanely bright green LED to tell you which port is in use: I need to hide it behind the TV as it is so distracting, which makes things tricky when you want to press the button to choose the other input.

Didnt work. I tried to use this to connect both a firestick and a DVD player to my projector, but neither of them worked using this switch.I would not recommend this product.

Intended to use this to connect 1 pc to a pc monitor and a TV. HDMI leads connected to both of these individually worked fine with pc receiving feedback signal from both, but when this switch was used to switch between the TV and monitor (only one at a time) there was no feedback signal from the TV reaching back through the switch to the PC. This resulted in no picture or audio from the TV. (note this was also the case when switching over the TV & monitor connections to check if this was only a problem with one of the ports).

Although my monitor has 2 HDMI ports it will not respond to two sources being switched.This solves the problem.Two sources into the switch and one out to the monitor.

Was very surprised to find this had a metal cover, was expecting a nasty plastic case but. Switching is clean and flawless, nice bright leds. Would buy again.

DOES THE JOB VERY GOOD WELL DONE TO THE MANUFACTURER.

It does the job, it works, what more can I say.
