OREI 4K HDMI Splitter 1 in 2 Out Mirror only with auto downscaling, Advanced EDID Management & 3D Support (UHD-PRO102)

It works well, always make sure you have a device plugged into "Out 1", and ideally, that should be the device that has the lowest resolution, because that's the resolution that is reported to the host when the EDID selector switch is in "TV" position. When that switch is in STD position, it reports as a 1080p capable device. Out 1 & 2 support up to 4k, but ( think) 3 and 4 are limited to 1080p (I could be wrong on that point). Frankly, I don't care because while I have some 4k monitors, my main use for this device only needs 1080p, and 4k is often a problem because cables at the venues I work in don't always support 4k).

I was trying to split a feed from an nvidia shield pro to several screens and no matter what I tried I could not get them all working at the same time and it drove me nuts! I tried 1080 splitters all the way up tp 4k. It didn't occur to me the resolution and refresh rates were the issue. I just figured I needed a "better" splitter. Really I just tried this one out of desparation, but it works perfectly! Finally!

I have a relatively old receiver that has HDMI 1.4 compatible to 1080p. I also have 4K projector so I would like to split 4K video and audio from the fire stick. I tried a few 4K video/audio splitters but the optical audio output did not work, and I tried a HDMI splitter before to use one HDMI connecting 4K projector and another HDMI to my receiver for digital sound output. However, it downgrade the 4K video to 1080p. After reviewing online, I decided to try this one. The 4K video output is excellent, but the HDMI digital sound output only supports PCM in my receiver, not several Dolby Digital system as my receiver has.

I'm using this to split the output from a Chromecast Ultra to a 4K TV and an AV receiver. My receiver is old and doesn't support 4K passthrough, so I need a direct connection from my Chromecast to my TV in order to get 4K video. But I also want the best possible sound for my home theater. So far it is working great. My TV recognizes the 4K signal from my Chromecast, and my receiver gets a 5.1 signal. I had a similar unit from another manufacturer, but it only worked for about six months. Reviews from this and other similar devices seem to indicate a very short lifespan. However, unlike my previous device, this one has an on/off switch, so I'm hoping that keeping it off when not in use will extend the life. Fingers crossed. EDIT: In using this with my Chromecast Ultra I've learned that every time I first turn everything on, the Chromecast reverts back to 1080 video. Every time I want to watch 4K video I have to go into the Chromecast settings and change the display back to 4K, then power cycle this device. So it works, but it's not ideal. EDIT 2: I discovered that the problem I was having with my Chromecast was because of the Chromecast, not the splitter. I started having Chromecast problems even when it was connected directly to my TV. I purchased an Amazon Fire Stick 4K Max and it works perfectly with the splitter.

Bought the UHD-PRO104. Worked great as advertised. Very easy to setup, plug and play. Can even be run using an external battery pack power supply. Did exactly what I wanted. It is also smaller than I anticipated, which is actually a good thing. Build quality also seems high. Will update if I encounter any issues.

This was exactly what I needed and worked great. For about a week! This morning was rearranging computer setup so unplugged HDMI cords then plugged it all back in and started it up. Could not get a signal. Then I decided to try a different HDMI cord and that worked but suddenly the bottom of the screen developed a static electrical thing and there were electrical sounds coming from the TV. I was afraid it was going to blow my TV up. I have my TV hooked up to my PC by the way so at first I also thought maybe it was my video card. In the end after much switching and checking HDMI cords and video cards and another TV it turns out that this device somehow burnt out my original HDMI cord and I can only assume was about to destroy my TV (and 2nd hdmi cord) with that electrical, whatever it was on the screen. I was so glad when I first got this because it resolved the hassle of plugging and unplugging different HDMI cords depending on what I needed. Unfortunately it only lasted for a week. I will never trust this company again as it could have destroyed my very expensive 4K qled TV.

Super happy with this device. Works exactly as I had hoped splitting an AppleTV to watch simultaneously on both a 4K Tv and a 1080p TV. Unfortunately when want to watch the 1080p SDR TV we have to set the AppleTV to SDR instead of HDR, but I knew that was a limitation of this device before buying as it was clearly stated that it can’t split an HDR signal to SDR. When we’re only watching the 4K Tv, we bump the video back to HDR. I can’t say I really notice the difference in quality between HDR and SDR, so we could probably just leave the AppleTV on SDR all the time. The box feels a little light and flimsy, but it’s a great value for the price and works well.

I have an ice cream shop with a multi-camera security system. I have two monitors but only one HDMI port on my camera DVR. This product I bought has one input and four outputs, which is more than I need (at the moment). It was super easy to install and I have crystal clear pictures on both of my LED monitors. Also, this splitter was less than half the price at Best Buy. Very happy with my purchase!
