OREI - 8K HDMI Splitter 1x2, Duplicate/Mirror Any UltraHD HDMI signal supports up to 4K@120Hz EDID HDCP 2.3 - (BK-102)

Bought it for my church. I have 1 signal being split to 2. Works great.

I do have maybe a "bit strange" use case for this, which is dealing with the connection of the Nvidia graphics card output to multi-monitor (3x32" 4k, and a 8k Samsung TV used as large monitor) setup with multiple computers, mostly in Linux (Fedora KDE). Where this came in was to have a stable EDID shown to the NVIDIA card, which helped to workaround issues caused from the switching transitions (whether switching computers or from screen locks, monitor power off transitions etc.). It "should not" be needed here, but it is presently the only way I have gotten this to work perfectly on all scenarios. I am not using split function at all, it is 8k in/out towards the Samsung, but I am using the EDID settings switch which "hides" the monitor info as well as presents stable config to a monitor. It also fixed some strange behaviors on display on normal use and improved the switching times. Perfect fix for my somewhat special case at least until Linux HDMI support catches up.

The delivery was quick and everything was packed well. The device is easy to use and setup. Unfortunately, I ran into a couple issues with this device when setup with a PS5 outputting to a large 4k OLED display and 4k desktop monitor. The issues below had workarounds, but best case scenario was sacrificing image quality on my large OLED. First problem: Severe discoloration on the desktop monitor when it was connected to output 2. Everything was purple with hazy shadows smearing across the screen. Additionally, the computer speakers I have connected to the monitor were outputting oddly, with sound effects missing and audible crackles. Switching the monitor to output 1 fixed both problems. The next issue isn't as severe, but it would bother me if I continued using the product. The colors on my larger display were washed out, way less contrast, and fuzzy on the edges of characters, level art, etc. The framerate was still very high, but the overall visual quality takes too much of a hit when plugged into the splitter. Which is odd because the quality on the smaller monitor was fine (after sorting out the purple screen issue). Using the splitter in my situation would only be acceptable if I was ignorant of the image quality my display was capable of without it. I tried using different cables, matching video settings, toggling other settings, but nothing could get the quality to match a direct connection. The images I attached depict the difference in image quality when connected to the splitter and when not. These images don't do either enough justice compared to seeing in person. However, it should at the very least show how drastically the visuals change with the device. The last picture is of the monitor when it is plugged into output 2.

Need this to mirror one into my tv and one into my capture card. Without this product, I would need to have the pc always on in order to play on my tv. However, this eliminates that as it outputs two signals at the same time. Plug in and play, no need to set up. The picture quality and the sound quality is good as well, nothing being diminished as far as I can tell. There would be the occasional screen going a little haywire, but nothing like a simple unplugging and plugging back the power source can't fix.

Received my 8K HDMI Splitter within 2 days. Connect my 3 HDMI cables from and to the splitter and plug in the power adapter. The splitter works with my LG's 65 inch OLED TV's 4K HDMI input and getting the audio top my Sonos Arc and speakers via eARC. The 2nd HDMI was connected to my HDMI4 input of my Yamaha Receiver. The splitter works by giving me 4K HDR video and Dolby ATMOS through my Sonos soundbar system. Now with the added splitter, I could also use the audio from the 2nd HDMI port to support DTS 7.1 surround sound at the same time and still used my regular audio sound system. Unfortunately, I couldn't connect with my latest WiiMax Ultra streaming pre-Amp which has a HDMI Arc input. However, I still have a HDMI input in my 4 port HDMI Yamaha Receiver.
