8K HDMI Splitter 1 in 4 Out 4K@120Hz 8K@60Hz HDMI 2.1 Splitter, Supports HDCP 2.3, EDID, HDMI Audio Out, for PS5/PS4, Xbox, Fire Stick, Blu-ray Player, Hue Sync Box

This is an excellent HDMI splitter. When you connect it, it is recognized as an HDMI SPLITTER, making it easy to identify on a PC. Both the video and audio pass through without any issues. The splitter includes LED lights that show when the input is active and when all the outputs are being used. It does require an external power source, which is included.

tldr: just don't buy it. I bought this because it claims HDCP support and downscaling. Here's my results for these 2: 1. Tested using PS Vita TV and PS3. On the Vita, it does not strip it. On the PS3, it worked and if I switch to a Vita, it also works. I question their implementation as my other 1.4/2.0 hdmi splitters do not have this issue 2. I do not have 720p only devices, but I have a Rokid Air and Rokid Max that support 1080p. Rokid Air displayed a partially corrupted image. It was like 21:9 and the areas to the right after 16:9 were corrupted. On the Rokid Max, only a blue 4:3 screen is displayed. 3. On TVs, it works well enough but on my testing, there are times when my smart plug turns on all my switches/splitters, I often have to restart this switch. I have not tested 120hz downscaling yet as I do not have any content that's 120hz.

I am currently using this to distribute the HDMI 2.1 signal from my PS5 Pro to 3 different OLED televisions in rooms that are very close together. They are so close I can use game controller in any room, and leave the PS5 pro in my office. Sometimes I want to play from my desk, sometimes on a 77” OLED in my den, and sometimes on the 65” OLED in my bedroom. Now I only need one game console and I can play on 3 TVs easily with great picture, all the features and compatability, no lag, and it’s a nice compact little box that hides behind the game console. You can’t even see it’s there. It just works after you set the dip switches correctly. Build quality is solid metal construction, not cheap plastic. Comes with power adapter. Nice splitter!

Hooking this up was simple, and now I can run my gaming console on multiple screens without a hitch. The picture stays sharp, and I don’t notice any lag. It’s small enough to tuck behind my console, so no extra clutter, just plug in, set the switches, and it’s good to go. It does need a power source, which isn’t a big deal, but I did have to tweak some settings to get everything working right. Works great for gaming and movies, but if you need downscaling, results might vary. If you just want to mirror screens with solid quality, it does the job.

only could get it to work in 1080p, tried every solution to work in 4k..nothing worked my old one works in 4k but wanted a 8k upgrade. not sure why but sent it back.

I installed this HDMI Splitter and it works well for running multiple displays at once. The 4K at 120Hz looks great, and I can also push 8K at 60Hz without any issues. It supports all the major audio formats, which is a nice touch for gaming or movie nights. The EDID switch is handy for adjusting settings depending on the device I’m using, and it connects easily to my PS5 and Xbox. Overall, it’s a solid splitter for anyone needing to mirror or extend their HDMI outputs.
