SIIG 1x4 HDMI 4K HDR Splitter - 4K@60Hz, HDCP 2.2, 18Gbps, Auto Scaling, Cascadable, Firmware Upgradable, 1 in 4 Out, TAA compliant (CE-H22Y11-S1)

I previously had two other brands of 4k HDR splitters. Both of them would show the screen in 4k@60Hz HDR. However, with one of them, the screen would go blank every couple of minutes and then come back on. With the second one, it would also go blank but only about every 30 minutes. Both of these splitters worked fine on any settings lower than 4k@60Hz. I thought there was no way that both could be bad, so I kept getting different brands of 4k HDMI cables. Nothing fixed the issue. So finally I read a review that this was the best splitter and gave it a shot. No issues at all any more. I also have 1 TV that is 3D and the other is not. I love the fact that it will let you configure it so that it only gets the settings from the first HDMI port if you want. This allows me to still watch 3D on the one tv without having to unplug the other tv. The other tv will just show no signal while I am watching in 3D, but gets signal with anything that is not 3D.

Tried two others before this one. Others has sync and HDCP issues and got very hot. This one was rock solid from the start. It has its edid set for 4k 60 HDR 7.1 audio by default and that worked great. However if you want to switch frame rates based on the content you need to set it to the edid learning mode so it can adjust the edid based on your environment. I have only had this a few days but I have had zero problems. Unit runs warm but not hot. I will adjust if anything changes but very happy so far. I use it with a ROKU Ultra source.EDIT: I suspect the default 4K 60 HDR 7.1 edid does not include other refresh rates like 24. It would be nice if it allowed at least 24/60 or even better 23/24/25/29/30/60 (basically pass thru anything). Also I believe the learned edid is lost when the unit is power cycled and I had to teach it again. With the default 111 edid set my Roku would not switch to 24 hz for movie playback . I think most displays that can take 4k 60 can do 4k 24 and it would make it a better fit (for North America at least) to support 24 and 60 on the first edid?

Bought this device to use with my NVIDIA shield, 70" 4K UHD Tv, and Optoma 4K UHD projector. They are all plugged into an Onkyo AVR. The original splitter I bought I didn't realize was only 4k @30hz. My TV, AVR and project do 60hz. I could do 1080p just fine but the original splitter kept glitching when trying it with 4k. Decided to purchase this one because it said it was compatible with my devices. Plugged it in and tried 4k, it blinked and seemed like the signal was glitching for a while then it stopped and works like a charm. Switching between and playing both the tv and projector goes without a hitch. I have several inputs from the shield to Spectrum box to a magic sing videoke and they all work perfectly. The older splitter would cause the video out on my onkyo to freeze and I'd have to reset my AVR. This splitter seems to have rectified the issue. Thank you for an awesome product!

Works in my Hyperion setup. Definitely passes through 4K@60Hz, RGB 4:4:4, YUV 4:2:2/4:2:0, HDR10 and HDCP 2.2 to the correct device. I keep it in EDID learning mode as the default "all on" mode got rid of all framerate options except for 50 and 60Hz. I can't really speak for the scaling function - I'm actually using a more specialized scaler between this splitter and the 1080p device. Haven't tested 24Hz or Dolby Vision yet - I may come back to update the review if I do.Just note: If you're planning on scaling a 4k signal with HDR down to 1080p, you're going to lose color data on the 1080p screen and it's going to look washed out in both HDR + 4:2:2 and 4:2:0 modes. That is, unless, you find the holy grail of scalers that can scale HDR colorspace down to SDR color space in real time. Or, unless your display can deal with HDR in 1080p, which I'm not even sure is a thing right now.Update: Dropping to three stars. One output started flickering and I've isolated the problem to the splitter. Might be returning.Update 2: Adding a star back because support is really trying to help and is exchanging my device as it may be defective.Update 3: Returned to 5 stars. Support has been great, they replaced my faulty unit and all is well.

Is a great product but I have problems to split the audio to Denon 1912 that use HDMI 1.4 signal and my Sony 4k HDR.Only passtrough PCM 7.1 or 5.1 audio, but when I select Lossless audio like Dolby True HD or DTS HD the receiver decode Dolby or DTS lossy formats.Xbox One X have issues, if you enable HDR, the receiver can't decode the audio and pass to the TV. Even in Blu-Ray and UHD BR.Only lossless audio work if disable in the tv the HDMI Enhanced (2.0 to 1.4).I will try EDID learning mode over 4k@60 hz 1111 settings...Update: no working in EDID learning to passtrough HD audio. Only work well 1111 with LPCM 7.1 or 5.1, if this passtrough only lossy Dolby and DTS.*Update:I contact the SIIG support a few weeks ago and after a test and sending the EDID info of my AVR-1912 they send me a personal firmware update. And after the first test's is working flawless!!!!The second output passtrough HD sound and output to my Sony 55x850D with HDR working at the same time.I really appreciate the time and the patience for my case and update my review..
