1x4 HDMI Splitter / Distribution Amplifier with Auto Video Scaling - 4K 60Hz HDR

Good quality and price

This SIIG 4K 1x2 HDMI Splitter with EDID Management was sold to me as new but tamper-evident seal was broken.Given this SIIG 4K 1x2 HDMI Splitter was only able to deliver a green screen to my devices (other splitters did work), either this device does not work as specified, the device was damaged by the previous owner, the device is defective, or some combination of all three.Look, I really want to support local to the Bay Area businesses even with Bay Area prices.I'm even willing to put up with used hardware sold as new.I will not tolerate defective hardware that wastes my time.

Pro: Company is professional and actually calls you back.Con: this device does NOT support extended display. If you have a laptop with 2 external monitors, this will not work for you despite what some q&a customers say.

Does exactly what it is supposed to do.

I would have given it 5 stars if it had a grounding lug. I have it hooked up to a TV and a computer. It was making me crazy because it would go blank for no reason, reboot and it would be okay until next time. Then I realized it was only when I went near or touched the splitter (static). Removed one screw and grounded it and the problem went away.

I Installed this amplified HDMI splitter in a new doctors office with four new Samsung TV's running from a HDMI medical receiver. All four TV's are on 100' HDMI cables. Setup was tricky and took a bit of patience to get all four TVs to the same format. Once running, they all look great. The original splitter I tried, failed, this one is great.

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!

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.

I bought this for the specific need of splitting my PS4 Pro's signal to my TV in 4K HDR and to my gaming monitor at 1080p for streaming. This does exactly that with no problems. If you ever need to swap HDMI ports for some reason, just make sure you do so before powering on any devices to avoid the issue of the splitter getting confused. Same goes for when you switch them back, turn everything off first. I went through a couple of other devices before finding this one, works great and is relatively low profile.

I bought this product to use with my Elgato HD60S as it is advertised to work with it to downscale 4k to 1080 for the capture card, and still be able to game in 4k on monitor. It worked well for about twenty minutes, then lost output of the 1080p signal to the Elgato.... It hasn't worked since.

Working great so far. My TV has no HDMI output, and my receiver is not 4k compatible. This was exactly what I needed to split the output from my source (PS4 pro) in order to send HDMI audio to the receiver, and full 4k to the TV. Working perfect with 4k 60hz hdr video, rgb and yuv format.

Why is this product not having thousands of full star reviews. I am loving it. I have hard to mix stuff that otherwise complain with unsupported connection (DirectTV receiver) along with multiple media players. Some sources are 4K / 1080p some with HDR support and some without. I have it connected with another switcher in front to handle the above referenced source selection. The selected source then feeds to this splitter essentially providing input simultaneously to a 4k TV, 1080p projector, 1080p only compatible sound system etc. All equipment display video or play sound at their native resolution without any glitches. This splitter just works!!! The autoscaling is awesome.

Please read to the end...To start this review, let me display my setup.My devices: (Source)1- Nvidia Shield TV.2- Roku.3- Cable/Sat.4- PC5- H96 Pro Android TV.All are connected to Denon AVR X-3300W To SIIG 1x4 4K 60Hz Splitter.The Display:1- Optoma UHD60 (4K Projector)2- Optoma HD27 (1080p Projector)3- LG PF-1500 (1080p Projector)Problems:Non of the setting could handshake with the display except1- (U.D.D.U - 4K 8-bit rec. 709 No HDR.)2- (U.U.U.D - 1080p washedout colors)Support are trying to rectify the problem with unsuccessful result so far.Prepairing it for return unless otherwise.Removed 2 Stars as Tech Support stopped rectifying device.Return in progress.Update 1.Rating now is 4 Stars as tech support is back in action to the next level.Update 2.It gets 5 Stars,Reason: The whole problem was the Nvidia Shield TV. I gave it a shot and Factory restored the Shield and thats it, all the problems dissapeared and the SIIG HDMI Spltter worked like a charm. Yes, its perfect. The tech support are amazing, they have been so helpfull and that was the main reason the SIIG got 5 StarsThanks.

This HDMI splitter seems well-built and does it says...it passes HDR10 and can downscale one of the outputs to a 1080p monitor. However, I wish it would work for passing Dolby Vision HDR. If connected to an Apple TV and two 4k TVs, the Dolby Vision HDR option disappears and you can only select regular HDR. I feel like Dolby Vision does look only slightly better so it's not a huge deal, but I hope there is a firmware update in the future that will allow this splitter to pass Dolby Vision.

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..

I needed a splitter to run 4k to one TV and 1080 to a second TV. I tried a couple of other devices with no luck before landing on this one. I had a bit of trouble getting this configured - it wouldn't learn 4k when both TVs were plugged in to start, but by setting up the 4k TV by itself then adding the 1080 TV after the device had "learned" its settings, it held the 4k state. It's been working for a month or so now with zero issues.

Had some issues at the start of use. No audio on 1080P monitor. Now have the EDID set in the learning mode and things seem to be working fine.Running one 4K and one 1080P monitor.

Finally, a 4K 60Hz HDR splitter that works with my Xbox One X and my 4K HDR TV’s.It sends perfect signals to both of my 4K TVs without a hitch.I tried other splitters that offer the same features but failed to deliver True 4HDR video to both TV’sThis unit feels. sturdy and is small enough to be placed just about anywhere. Simple instructions make it easy to set up. I definitely recommend this unit.It delivered as it promised.

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.

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?
