HDMI Matrix 3x2, 4K HDMI Matrix Switch 3 in 2 Out Switcher Splitter Box with EDID Extractor and IR Remote Control, Support Ultra 4K HDR, 4Kx2K@60Hz, 3D/1080P，HDMI 2.0b, HDCP 2.2

It reached my expectations.

This fits a small niche I have a second monitor When I have less need for it I use it with a Firestick. This makes switching cable and back of screen impute buttons easy and the remote makes switching back and forth very quick and easy. If you have a use this is a very good product

I've bought several of these devices thru the years. It lets me use multiple devices to send signals to multiple devices. Only negative is it has red lights. I never like red lights except to tell me to stop or be alarmed. It's a negative signal and I'd prefer if it was green, tan, yellow, blue violet. Just not the angry red. I'll still use it but probably replace it when I can.

I got this to duplicate the HDMI signal to 2 TVs. One of them 4K the other 1080p, the device automatically downscales both to 1080p and now it won't send 4K signal unless I restart the matrix. It also seems to be corrupting the video signal. Saying it's HDR when I definitely have a regular 4k TV not HDR. The Roku can't make sense of it. Also, the audio switch on the front (TV/2Ch/5.1) is useless half the time. It will only work when set to TV for the Roku. The PlayStation worked on TV and only sometimes when set to 5.1 overall using this device has been extremely confusing. Seems to have some compatibility issues.

I have two of these hooked up to all kinds of things like a retrotink, PC/NVIDIA GTX 1080, roku ultra 4k, Yamaha surround receiver, component to hdmi converter. All work perfect even at 480p! Compared to other way more expensive brands this actually works better!! Only downside ive noticed is the 3.5 audio out sounds like its dac is maxed to 100% and you cant change it.it needs to be @ 50% because the audio does crackle. This doesn't happen over hdmi signal thankfully! I recommend this unless you want high quality audio from the 3.5 out than your search continues.

Update: After less than two months, but past the return window, the thing constantly resets and flashes lights. Would not recommend. -=-=-=-=-=-=-=-=-=- This has done pretty good for me, once I learned some of it's shortcomings. If you are switching between relatively newer equipment and displays, it seems to work well (I am only switching 1080p sources and displays). My problem lies i a low powered Intel NUC with onboard intel graphics and an Old TV. I have the intel driver shrinking the display to +/- 90% since my TV has an overscan (It makes the image smaller on my second display (a monitor) but that is OK). Sometimes, when switching both outputs to an input that is NOT the NUC, the NUC goes a big poop and won't display again. I have tried switching the EDID to 1080p stereo (The EDID switches are VERY VERY hard to switch, you will need a pair of robust needle nose tweezers to reach in there and switch them), that did not change anything. The remote also has to be pointed straight on, it sometimes takes a few times to change it. But this is awesome if you are like me and have many displays and many inputs :D (I have three monitors/TVs and many inputs, one display never changes)

I host a trivia contest weekly at a local pizza place. I use 2 laptops during this contest. 1 has questions on it and the other has a scoring spreadsheet. I wanted to be able to control what was on a TV hung on the wall behind me during the contest. This little box works perfectly for that and gives me room for future expansion. I plug each laptop into separate inputs and then Output A is connected to the TV. I am able to easily change between the questions and the score with a push of a buttton.

Pequeño y efectivo, para cambiar de entrada se toma entre 1 y 2 segundos pero funciona perfecto.
