SP12H2 4K HDMI Splitter - 1x2 HDR, Dolby Vision Atmos, Down Scaler, 4K 1080P Sync, 4:4:4, HDCP2.2, EDID 4K5.1/4K7.1/Copy, For Game, Xbox, PS5, Roku

I got this to get the most out of my 4K TV. My Fire TV Stick 4K is connected to a 'standard' HDMI splitter sending signals to my 4K TV and another regular 1080 HD TV in the kitchen. The problem with this setup is that the Fire Stick negotiates video/audio between the 2 TVs and ends up using the lowest common denominator - plain 1080 HD and never uses 4K streaming. Never got full use of my 4K TV until I re-discovered this device. Using the 'copy EDID' feature, the Fire Stick thinks it is connected to 2 identical 4K TVs and enables 4K streaming. I then set HDMI 2 to downscale to 1080 (for the regular TV) and everyone is happy. An interesting side note is that I purchased one of these from another vendor (Avstar) back in 2023 that has an identical model number to this one by EZCOO for exactly the same price, That one was to solve similar audio issues when negotiating to allow full Dolby to pass to my receiver. Prior to this, my receiver would only negotiate plain old stereo. Bottom line is that I can now watch full 4K UHD streams with Dolby sound. These devices are magic. Update: I recently noticed that my standard HD TV (in HDMI2) picture looks pretty bad when streaming a UHD movie using Dolby Vision (DV) HDR. I guess this is because the standard tv doesn't support DV-HDR and force feeding it that signal just doesn't look right. Picture is washed out and colors are muted. This is my bad, not a ding on the splitter.

Basic review: Bought this for my Yamaha RX-A1080 and it's working perfectly. It took me all of 3 minutes to set up, and it is exactly what i needed. 5/5 would recommend. Technical Review: My problem may be rather unique, or maybe not. But this is the specific and technical review wish i could have seen before placing my order. I hope it helps someone else. My setup has a living room TV that's 4K and a kitchen TV that's a cheap 1080p which i wanted to always be matched. My AV receiver is a newly bought RX-A1080 from Yamaha, who's dual HDMI outputs were supported to take care of this for me. However the RX-A1080 has two problems. It's dual HDMI out is a mirrored HDMI out (as expected) so when i connect my 4k TV and my 1080p TV the signal is downgraded to 1080p for both of them. It's second problem is that it refused to see any of my other EDID emulators to trick it into sending 4k to both and kept flickering. Additionally my 1080P TV being cheaper, hates trying to downscale and usually just says "resolution not supported" when fed 4k signal through an EDID emulator. This device solved both problems perfectly. i used my laptop to test to make sure it was being seen as a 4K display (which it was) when it's EDID switch was set to 4k and it sent a 4k signal. Connecting my laptop to the HDMI in, and the Kitchen TV to HDMI out 2 (I left HDMI 1 empty and not plugged in) I flipped the switch to downscale the output. and boom, as far as my computer thought, 4k content was being output (including tiling my wallpaper as it does on any 4k display) but the TV was happily displaying the signal with no issues. When plugged into the Yamaha (which had been having a fit with the of EDID emulators) it worked perfectly and instantly. I have not attempted to use it as a splitter since I only needed the EDID and downscaling off an already split signal, but I'd assume it would work perfectly in that capacity as well.

The Ezcoo SP12H2 is a remarkably powerful device… when it’s working properly. It functions as advertised: passing a 4K signal with metadata to one device (in my case, a Samsung S90D television) and simultaneously downsampling the signal going to another device (in my case, an Integra preamp with HDHI 1.4 inputs). This solved a big problem for me. My preamp doesn’t have eARC and it can’t handle HDCP, so I could only get lossy 5.1 audio via optical SPDI/F. Now, with the Ezcoo, I can watch a 4K Blu-Ray from my Sony player and get Dolby TrueHD via HDMI to the preamp. Huge win! The Ezcoo offers another bonus for my particular television. The S90D does not have Dolby Vision. Normally, the upstream device (Blu-Ray player, Firestick, etc.) recognizes this and doesn’t bother sending Dolby Vision data to the Samsung TV. However, when I installed the Ezcoo, the upstream device asked, “Do you want to enable Dolby Vision?” When I did so, Dolby Vision metadata began streaming to the TV. That didn’t magically give me Dolby Vision on the Samsung, but the Samsung’s HDR processing apparently does accept some of the Dolby Vision metadata, including Dolby Vision tone mapping, which increased detail in dark parts of the picture. So the Ezcoo actually improves the appearance of content that is encoded for Dolby Vision. Some reviewers say the Ezcoo down-samples the video signal to 1080 or makes the picture look “washed out” (i.e., colors are desaturated and flat, HDR deactivated). Yup, I experienced all of that. It’s not the Ezcoo’s fault. Those problems happen when the television doesn’t establish a proper handshake with the upstream device (disc player, gaming console, streamer, etc.). Normally, when I attach a new upstream device to my Samsung TV, I get a message saying “Optimizing for (that device).” I usually get that message when installing the Ezcoo inline with an upstream device, and everything works fine. However, if I don’t get that message, that means the television is in default mode, only recognizing a generic upstream device. That’s when the pictures ends up looking desaturated and sub-4K. To ensure a proper handshake between the TV and upstream device, I do the following: 1) turn off television; 2) connect Ezcoo to upstream device, television, preamp as directed; 3) turn on Ezcoo, preamp, and upstream device; 4) turn on television; 5) go to “connected devices”; 6) follow steps for “connecting new device.” During the connection process, you should get the “Optimizing for…” message. Here's the real problem: With the Ezcoo in the chain, the handshake between devices may be unstable, particularly if you switch the upstream content a lot. If I only use my disc player to watch Blu-Rays, the Ezcoo-based system tends to run dependably. However, if I watch a Blu-Ray and then switch to streaming on my disc-player, the handshake may get corrupted (causing any of the problems described above). It doesn’t happen every time, but it’s frequent enough to be annoying. This is an issue with every upstream device I’ve tried, including my Nvidea Shield and Amazon Firestick. The signal may go screwy or cut out entirely when I switch between apps (example, switching from YouTube to Disney+). Fortunately, there are two easy fixes for these problems. If the television still recognizes the upstream device, you can do a soft reset. (I can confirm that the upstream device is recognized on my Samsung when the name of that device appears under “connected devices.”) To do a soft reset, use a paperclip to push a hidden button on the Ezcoo. Or unplugging the Ezcoo does the same thing. If that doesn’t work, you may need a hard reset, which involves the following: 1) uplug HDMI connection between Ezcoo and television, but keep all other connections; 2) turn off television; 3) turn on television and verify that upstream device is no longer listed under “connected devices”; 4) make sure Ezcoo and all connected devices are powered on; 5) reconnect Ezcoo to television via HDMI. At this point, my Samsung goes into the “Connecting New Device” routine and it should give me the “Optimizing for…” message. This is the reset process that works with my system. It’s not documented or recommended by the manufacturer. It involves hot-swapping components, which may cause problems with other equipment. This may not sound like a ringing endorsement of the Ezcoo, but, despite these issues, I am still enthusiastic about this little device. I tried much more expensive solutions, including the HDFury Arcana, which wasn’t suited to my purposes. I also tried splitting the audio and video directly from my Sony disc player and from a Panasonic DP-UB820. The Ezcoo is the only device that has successfully bypassed HDCP, splitting audio and video signals without degradation. I’m willing to tolerate some (fixable) instability if it means I don’t have to buy a new AV preamp/processor.

Amazon Prime Video, for some reason, restricts anyone with a 1080i or 1080p display from seeing titles in Dolby Atmos (even though you pay for ad-free). The SP12H2 eliminates that restriction because it makes the Fire TV Stick think you have a 4K display. It works on both Fire TV 4K Sticks and Google TV 4K Sticks. In fact, on the Google TV, there is an added bonus: because since the Google TV Stick thinks you have a 4K display, it enables every single format below that, such as 1080p 30Hz, which your old display might be able to use but which is normally not a visible choice (forcing you to go down to 720P). This is a 5-star product!

Causes audio drop-offs. I have two of these, on two different sources (4 TVs). BOTH causes audio dropoffs with 4K, Dolby Vision, and HDR. These might work for simple 1080p, but higher res or newer video formats causes them to stumble after a few minutes. There are better quality splitters that work fine.

Security monitors set at 4k and 1080. Plugged in and presto. It's functioning as it should. Working great for separate screens image settings. Not sure about audio passthrough. I wasn't attempting to get Atmos or any high end audio output. We were at a lower resolution and monitors were pixelating like crazy so I had to change my large monitor to 4K. Did the job!!

Super worth it splitter for PlayStation 5 streamers or those with home theater setups! I thought I'd need to upgrade either my TV or AVR to be able to fully enjoy 4K HDR Bluray disks & 60fps gaming on the PS5 along with HD/lossless audio. My Hisense TV doesn't have eARC, while my Sherwood AVR can't pass through 4K + HDR + 60Hz via HDMI. So it was a choice of either connecting direct to the TV via HDMI to get 4K HDR 60Hz, but with only standard 5.1 Dolby Digital or DTS as my audio options connected via optical or ARC. Or, if I use HDMI passthrough, I can get 7.1 Dolby TrueHD or DTS HD Master audio via the AVR but I'm limited to 4K 30Hz only with no HDR on the TV. I've already tried other supposed 4K HDMI splitters, but they would either downgrade the video to 1080p or audio to stereo when splitting the signal. But I found a YouTube review of this EZCOO splitter showing how it can properly split 4K HDR with full 7.1 HD audio. Saw it on sale on Amazon, and for the price I thought it would be worth trying. Out of the box, with the default settings, it didn't work right away. But after flicking some switches on the splitter and a PS5 restart, I was able to get what I wanted, 4K 60Hz HDR on the TV and full 7.1 HD audio (True HD, HD Master or PCM) through the AVR, without using passthrough! Proof is in the pictures. Here's what worked for me: TV connected to Output1, AVR connected to Output2. Set Scaler on Output2 to ON. Set EDID to 4K. Important things to take note: Make sure all your cables are at least HDMI 2.0 compatible. Plug the splitter into a USB port with enough power (I tried it with a USB hub and it didn't work, but it works with the PS5's USB plugs). And most importantly, especially during initial setup, make sure your TV and AVR are both already turned ON first BEFORE you turn on your PS5. Their customer service is pretty great too. When I wasn't able to get it to work at first, I messaged them and they quickly responded (although I was actually able to figure it out for myself before I got to read their reply). Anyway, thanks to this device, no need to upgrade my TV and AVR for now, or maybe until all the PS5 HDMI 2.1 issues get ironed out. 🙂

Most the time video goes off for a few second. You'll see a black screen. Whatever setup you put the black screen will appear for few second. I try everything even new charger but still have same issue.

Waste of money
