4K 1x4 HDMI Splitter by OREI - 1 Port to 4 HDMI Display Duplicate/Mirror - Powered Splitter Ver 1.4 Certified for Full HD 1080P High Resolution & 3D Support (One Input To Four Outputs) - HD-104 Black

I bought this HDMI switch because I needed to connect several devices (laptop, console and other devices) to a single TV, and the truth is that it perfectly fulfills what it promises.The installation is super simple: you connect the cables and that's it, it works without configuration. In addition, the remote control makes everything more comfortable because you can change the font without getting up.

Item works great! I'm able to have two different inputs be displayed on 4 diferent outputs. Makes switching outputs easy for meetings. No more swapping cords around!

it works with no problems

Excellent Product Except For the Instruction Manual with light color extremely small font size and doesn’t tell user what they really need to know and understand for proper setup.Customer Support by Seller is meaningless.See Below For Vital Information.AC Power Supply IN MUST be BOTH plugged into unit AND screwed down with nut. Only Outputs C & D are for less than 4K. MIX 1, 2, and 3 modes are for Downsizing 4K, if necessary. Many non 4K TVs do this automatically and you don’t need to use Mixed Modes. Try First without MIX. The DIP switches are not to determine what is output from this device but to tell Source Device (such as DIRECTV) What video & audio signals to send to Input at the most minimum required level (Stereo TV does not know what to do with Dolby Digital 5.1 signals). Outputs C & D TVs not 5.1 + audio will not play the audio signal, even using HDMI cables, unless mode dip switches are set to stereo. However 4K tvs can remain Dolby Digital (5.1) versus Stereo using Digital Optical cables directly to 4K TV. A Digital Optical Splitter/Extractor (Less than $30) may be required if using a sound bar as an example so as to receive both Audio Outputs from this device and other 4K Sources To your 4K TV. Once you know and use this information to set up product it works great.

I used this item for an event recently to distribute various images to various screens. It worked a charm. A few notes:Even if you switch between two active sources, there will be a blue screen in the process of switching. In a dark room with a big screen, this will be almost a blinding light for an audience if switching from a dark source.I did not try the RS232 switching feature. I did not try the remote. However, I ordered this unit for the RS232 switching feature. Perhaps I can update this review after I try both the remote and serial control.The unit looks and feels solid and I enjoyed using it. The metal case is great. I'm looking forward to implementing this unit into a bigger project once I get talking to it with the serial port.** EDIT 1: DEC 15 2024 ** I just had the same event, new year, and the matrix worked great again. I have the same feedback as I have not tried to operate RS-232 just yet.I would, however, like to offer a constructive criticism to the product design. It would be great to have a screen printed I/O listing on top of the unit at the back; with this information listed under the inputs and outputs on the back, there isn't a good way to see it when trying from the front or above the unit to plug things in. I took some board strip tape and manually labeled it on top, but it would be a great addition to the enclosure design.

Pretty much plug and play - Connected it and it works great! I am quite confused by the EID setting options so I left the default setting alone and it worked. Only thing though - It has several blue leds on the front and man, they are almost blindingly BRIGHT! No way to turn them off so I had to cover them with a piece of paper. Still, I am very pleased with the purchase! But please note - This is NOT some sort of a port expander that it used with a PC to display different displays from one source as some customers have expected. This is a duplicator - Displays on one or more displays per input.

Worked great. Signal very strong. Video quaity is excellent. No issues with transaction.

I have the output from my receiver (BluRay, media player, Amazon Firestick, etc.) going to this splitter and then to the TVs in the Living Room, Dining Room and Kitchen. It's nice to be able to move from room to room without missing anything.Picture quality is good. It works well for me. Recommended.UPDATE 5/08/25 Just received the third one of these we have had. The first lasted from 2014 to 2022, the second from April 2022 until this month when it started acting up. It would die, but if I unplugged it, and plugged it back in 30 seconds it would work. After the second or third time it would stay on the rest of the day. And one port went out about 6 months ago. I hope that the new one will be as long lived as the first one! Last one cost $28.00 and this one was just under $16, so that is really nice.

As Described
