4K HDMI Splitter 1 in 2 Out Copy Same Content to 2 Screens (Mirror Only)

Works like a charm. I used from my Roku device and split to two different TVs on adjacent walls so I can watch the same program if moving around the room.

I bought this for home karaoke so that I could connect my laptop to both the TV and a projector. It feels pretty flimsy, and it requires using an outdated micro-USB cable, but it was just about the cheapest option I could find, and it’s getting the job done! I’m extending the desktop to the two screens so that I can show the lyrics on those while viewing the controls on my computer. Here’s a tip: I was able to plug the USB cord into the powered hub adapter rather than using a separate power adapter. This allowed me to use the short USB cable provided. You will need 3 HDMI cables (not included). I was also able to output sound from my laptop through one of the HDMI cables to my TV/Receiver. Just what I needed.

Not a good item. Does not work as described. Return window closed before I tried the installation

Works great for my TVs. I didn’t even need to connect to optional power.

Works fine does not come with the extra HDMI cord showing picture ,or it is not attached as others are You need to run power wire also not shown in photo for no lag or quality issues noticed

My use: Roku stick plugs into the input. One output connects to the TV via a short HDMI cable. The other output has a longer cable to a HDMI to RCA adapter for audio output to my stereo system. TV picture seems just as good as when the Roku is plugged in directly, and now I have my good stereo sound again.

It works good, easy to use. But and a big but at that if you plan on using this for small projects I recommend it, but it get way to hot, has no vent ports so it can cool down, and the HDMI ports on it get way to hot to touch, oh and when it get to hot it will let you know by loosing signal on your TV or PC monitor. I maybe played one game for an hour and 30 minutes with both TVs going and it almost fried it's self.

These HDMI splitters are plug and play. Used in a conference room with 2 sets of TVs and a mirrored dual monitor setup. Depending on the source HDMI connection, these splitters may not need external power. In other cases, you will need to use the included micro USB cable. Not sure why Micro-USB is still a thing anymore but that’s what this uses. Connecting to a GMKTec Mini PC this worked standalone. However on a Beelink Mini PC, the displays kept dropping out due to insufficient power. Splitter is very compact and worked well with the 1080p Vizio TVs we have. Also includes a short HDMI cable for the source input as well which is a plus.

Not Bad

Good

Funktioniert wie beschrieben (1 In, 2 Out). Allerdings wird für den Betrieb ein zusätzliches Stromkabel bzw. Netzteil benötigt.

Using for two security monitors. Perfect solution.

Doesn't work
