4K 1x4 HDMI Splitter 1 in 4 Out by OREI - Ultra HD @ 30 Hz 1x4 Ver. 1.4 HDCP, Power HDMI Supports 3D Full HD 1080P for Xbox, PS4 PS3 Fire Stick Blu Ray Apple TV HDTV - Adapter Included

I've purchased a ton of products from Amazon over the years and I think this is my first negative review (or review for that matter). The device worked for about a month. All of the sudden I started to notice artifacts and then all my displays started to turn off/on. I swapped cables but noticed no difference. I eventually took the device out of my setup and then everything returned to normal without the device in the rotation. I contacted their support for an RMA, but noticed they required all RMA shipping to be covered by the purchaser which doesn't make sense if the product dies within a few months after purchase. I had to follow up to get a response as well. Overall, just wasn't worth the cost to go through all the hassle of doing an RMA especially when other reviewers noted the same experience. It's a shame because when the product worked it did exactly what I needed it to.

I bought this splitter to drive 3 monitors for a portable VJ setup. I've used it twice. The first time, it worked well but required a couple power cycles to get the monitors to synch properly. The second time, one of the monitors came on for a split second and everything quit working. I'm not sure what happened, but all of the monitors are completely dead now. One of them won't turn on and the other 2 have broken HDMI ports; the VGA ports work OK. The worse part was it happening in the middle of a VJ gig. Luckily, we had access to a big screen TV that allowed us to finish our gig without canceling. Stay away from these splitters if you value your electronics; they are junk! I learned the hard way. Hopefully HP will be kind enough to replace or repair the broken monitors instead of having to buying new ones...

This OREI HDS-104 1x4 has been a good product for me. I bought this in Jan 2018 and have been using it 19 hours a day since then. It stays on 24 hours a day. It is hooked to a Dish Network 722K DVR/Receiver with a 6 ft HDMI to one TV and a 50 ft Blue Rigger HDMI cable to the other TV. I don't use 5.1 or 7.1 audio, just stereo, so I can't speak to multichannel audio but the stereo audio is fine. I have seen no degradation in the video on either TV with both TVs on, at least that I can see. The 722k puts out 1080i 60hz. I have only 2 TVs so I haven't tried more than 2 ports at a time.

I've tried other HDMI splitters and matrix switches with mixed results and often had ports that went dead, dropped signals, and synch failures. Frustrating and probably typical unless you want to pay big bucks for professional grade equipment. However this little splitter has worked fine so far with no ports going dead and no drop-outs. I use a mix of 2 Visio screens, 1 LG, and one Dell monitor with a HDMI to DVI adapter cable. All connect and synch perfectly.

I ordered this because the one I have doesn't have a power switch and I wanted that feature. The first unit arrived and had a buzz coming from the power supply. It wouldn't turn on or work in any way. I exchanged it and the second unit had the exact same thing going on. Not worth the hassle even though the exchange and return process from Amazon was amazing.

Splitting 1 to 3 and it works great, have not needed tech support. Very easy to understand and hook up

great product and it work as it should be... connected using Samsung MHL on my Samsung Galaxy Note Edge then to my Pioneer 4000NX plus to my two other monitor both using HDMI connector... it gives quality video without any degration in picture quality. Better than the one i returned at Bestbuy with only two output with almost the same price but didn't work

I ordered this product to split signal in cable box to tv and projector after looking at many other competitors in Amazon this one appear to have the most information and professional presentation in the site. A major concern was length of HDMI cable and picture quality since I run a 25 foot long HDMI cable to the projector. After connecting and testing it both pictures to tv and projector were excellent no imperfections no changes in picture quality were noted. Overall it did what I expect it to do.
