EZCOO HDMI Splitter 1x2 4K 60Hz 4:4:4 18Gbps HDR Dolby Vision HDCP 2.2, Audio Breakout SPDIF Optical 5.1CH, Support HDMI Scaler 4K 1080P Work Together, with Firmware Upgrade

The splitter works!I am using an OPPO 203 UHD BR player. The splitter passes 4K HDR signal to my TV, while feeding downscaled 1080p signal to another device.Here are the situations and results:Only 4K input -> Both 4K and 1080p outputs are perfect.4K with HDR 10 -> Perfect as well.4K with Dolby Vision - Here comes a little problem. My TV shows 4K and Dolby Vision content with no problem at all. For my other device receiving downscaled 1080p signal, the color is weird, I believe the HD device cannot process Dolby Vision data. However, please correct me if I am wrong, so far none of the HD device can process downscaled 1080p signal with Dolby Vision. So there's not the splitter's fault.I noticed that if I change the switch of "downscale" from yes to no , or vice versa, I have to unplug the power cable to restart the splitter before the change can be effected. It doesn't bother me at all as I always need downscale function on.I must give the splitter 5 stars considering the stability and price.Update on 20/7/2018:After I upgraded my player's firmware and TV, the splitter stopped working with DV. I have raised the issue with the seller and they solved the problem very shortly with excellent customer support! Now the splitter is working perfectly well. I wish I can give more than 5 stars!

I had researched this item. It has a nice feature set for the price and generally good reviews.I received the item, its well packaged. The item itself feels durable and high quality.I plug everything in, and its working 2 x 4k steams with HDR, and audo out via optical all working.All working, except when its not going to a black screen, dropping signal 5-10 times every 10 minutes. The individual 4k outs, will black out either independently or simultaneously, and the optical audio will always cut off with it. This makes the device unusable for me and effective paper weight, while I try to find a similar solution.I requested a replacement from Amazon, thinking it was a defective unit, but same deal with new unit. I do not experience this issue at all when directly connected to either display. Their website is of no use, with very little information, and with bad grammar and English. I tried to find a firmware update, but the link just goes to a different device page.I gave it one star because it doesn't do what it needs to do for more than 4 minutes and was effectively a waste of my money.

EDIT 5/3/2018: After writing my review, the company contacted me and sent me a working unit. I guess my original was damaged during shipping. This replacement works as intended and I couldn't be happier.I like build quality and design, but the splitter I bought only half works. Output 1 works just fine. Output 2, however, keeps trying to send a signal but make the second display just blink. I've tried toggling the scaling switch and multiple devices and displays. I would have exchanged it, but by the time I was done messing around the item was taken off the store for some reason. I forgot about this thing, but I got a reminder to write a review, so I guess it's back on the market. If yours works, awesome, but make sure you act quick if you want to exchange or return.

My goal in purchasing this device was to split a signal from my AppleTV 4k so that I could send Dolby Atmos to my Denon receiver (which does not support Dolby Vision) while sending Dolby Vision to my Sony OLED TV. This product says that it supports both Dolby Atmos & Dolby Vision.... Which it does. HOWEVER, in my case, it will not do it at the same time. For anyone in my situation where you have an audio receiver that can decode Atmos but not Vision, and a TV that can decode Vision but not Atmos, this device will not work and here's why... What this box does, it does well. It takes a signal and splits it... However it first looks to the FIRST receiving device that you connect to it to determine it's decoding ability. If I connected my Atmos capable receiver to it first then I got Atmos. If I connected my Vision capable TV first then I got Vision. Because neither receiving device can decode both, both Atmos and Vision were never sent/split from the EZCOO device. I have changed my review and bumped it up a few stars. The device does what it does well, but will not work for me. :)
