1x4 HDMI Splitter, 1 in 4 Out HDMI Splitter Audio Video Distributor Box Support 3D & 4K x 2K Compatible for HDTV, STB, DVD, PS3, Projector Etc, Duplicate/Mirror Screen Only (Not Extend)

It just works. Plug in power, plug in HDMI cables, done. I'm using two of these on a pretty long (about 80 ft) HDMI run. The first one at the HDMI source almost did the job. Only occasional signal dropouts. I added the second one at a connection between two cable sections about halfway down the run. Signal is now strong with zero drop outs or flickers. Highly recommended.

Good product works good

This was well worth the buy works like a charm for my drawing tablet

Does what it’s supposed to do. Good quality for the money, just wished it was a litter more specific about what the product was.

Good products/ good service

There are tons of these HDMI splitters from tons of no-name companies so already we're off to a sus start. I picked the one that looked the best and, well... Garbage product, when plugged into a power strip, the power would cut out randomly and when I plugged it into a computer for USB power, it installed spyware. Now it's not even working, displays static.

I work as an e-sports tournament organizer and this little thing works wonders for our multi monitor setup.

I feel very satisfied with this 1x4 HDMI signal splitter. Its compact and functional design allows you to connect an HDMI source to up to four screens simultaneously, without loss of image or audio quality. Compatible with 4K and 3D resolutions, it is ideal for both entertainment and professional presentations.Installation was quick and easy, practically plug-and-play. In addition, the construction of the device is robust and conveys confidence in its durability. I've used it to connect my NVR to multiple displays, and everything works perfectly.Definitely, an indispensable tool for those who need to share HDMI signal on multiple devices without compromising quality. 100% recommended!
