HDMI Splitter 1x4 4K 120Hz 4:4:4 HDR 8K 60Hz VRR G/Sync EDID Switch HDCP 2.2,HDCP 2.3 Bypass,Duplicate/Mirror,EDID,Copy,Downscale, HDR,D-o-l-b-y Vision Atmos for Game PC Xbox PS5 Roku Fire TV

Works very well to integrate a variety of TVs / projectors and various 4k and HD players. The biggest issue when mixing HD/4k and HDR/non-HDR is all of the EDID mess that is inherent in such a setup, and these splitters make fixing the resulting EDID problems simple while still passing through 60Hz 4k HDR signals with 7.1 audio to the TVs that support those streams.I have not tested the downscaler as I still rely on the player to do the downscaling, but everything else seems to work as advertised, and the units don't die after a year like some other brands...

Lasted about a year, but CEC no longer passes through. I have to remove it from my setup in order to get CEC back. Emailed easycool a week ago but have gotten no response.

Purchased this splitter as a work around to get the Xbox Series X to output 4K 120hz to my TV, and a second down converted 4K 60hz signal to my Hue Sync box as the Sync box does not accept 4K 120hz. After a couple quick flicks of the EDID and downscale switch settings it was time to connect everything. Used the ultra high speed HDMI cable that came with the Xbox to connect it to the splitter input. Then used another ultra high speed HDMI capable from output 1 on the splitter to my LG TV. Then connected a high speed HDMI from output 2 on the splitter to my home theater receiver (which is ultimately connected to my Hue Sync). Turned everything one and had no issues at all. TV is receiving the 4K 120hz signal as verified through the Xbox display settings. My receiver is getting a full Dolby Atmos signal. And the Hue Sync and all lights work perfectly. So if you are looking for a simple work around solution to not have to sacrifice Xbox performance and still enjoy your Hue Sync setup, buy with this splitter with confidence.

The per-output downscaler on this unit is a great idea but extremely poorly executed. It does not work in any usable manner most of the time.First, it messes up colors with both the PS5 and XSX in 4k120hz mode, even without VRR. Obviously a certain level of quality will always be lost due to downscaling, but this is beyond that. Reds are orange and the picture is very dull in general.Second, unlike Ezcoo's more expensive 1x2 splitter, this one will not downscale >18Gbps VRR content at all. If the input signal is 4k120hz VRR, the downscaler is unable to output anything. Turning the downscaler off makes the picture immediately appear. Now, given the rarity of VRR capable downscalers and the relatively cheap price of this unit, perhaps it is fair that it just can't do it at this price point.Finally, even with content that the downscaler did work with (even if the colors were wrong), the signal dropped out every now and then for seemingly no reason. With the downscaler turned off, there were no drop outs. Even if you do not care about the color issue, these drop outs alone make the splitter unusable to e.g. feed an older AVR.I've reduced an additional star because Ezcoo's support was extremely unhelpful. I sent them a detailed report about all these issues, and although they did respond after a few days, the response was useless and it was clear that they at best skimmed through the email if even that. Literally, their response was that "4k120hz results in 1080p120hz" and to make sure that the output device supports that, completely failing to address any of the issues, and had they actually read my email they would have seen that my device was perfectly capable of 1080p120hz too. Once I pointed out that they did not address any of the concerns there was no further response.Here's to hoping they can fix some of these issues in a future firmware release but since they don't seem to test their devices, and fail to accept issue reports, I doubt anything will change.Not recommended for anyone who actually needs downscaling.

Muy buen producto

This splitter is not like a regular splitter. It's more of a mirroring splitter that is able to do 4K@120Hz. I had this for about a month now. Here are some pro and cons below.Pros* It will do Dolby Vision with Atmos but not right out of the box. You will have to change the EDID setting to have 1 be down. This will allow DV to work but it will also give false positives to your output devices so keep that in mind. For example your Samsung TV will show that it could do DV when it can't.* I got this hooked up to 2 4KTVs @ 120Hz, a 4K projector, and to a Phillips Hue Sync Box. Everything is working great and I could have multiple displays all on at once. All in 4K! In 120Hz if all displays are able to do it, see one of the cons below.* No more having multiple splitters like a family tree diagram. You could only do so much before the imagine quality starts to fall apart and won't work altogether. I'm using this device behind a 4K@120Hz HDMI 2.1 switcher and it's been great so far.* It could downscale if needed. I don't use this feature as all of my outputs are 4K.Cons* HDMI-CEC doesn't work and this is why I'm knocking one star off. It stated in the description so I expected to have it. It does make sense why it doesn't have it though or you would have multiple displays turning on all at once since this is a mirroring splitter only. Which leads to my next con.* No output switcher button. As much as mirroring is awesome I would trade that for working CEC. I like to have control of what displays are on or not. Since you can't switch outputs there is no need for a remote as well.* If an output isn't 120Hz capable then guy would need to switch the device down to 60Hz to have it work. So for example my 4K projector is only 60Hz so I would have to lower my refresh rate on my Xbox SX or PS5 to 60Hz for it to work. This is a small hassle which would've worked out if we had an output selector button. That way the devices itself could auto adjust for the new refresh rate that will be needed to make it work. Since it's mirroring only it will not auto adjust correctly.* I tried to run a 25ft or so optical HDMI 2.1 cable and was only able to get 4K@60Hz. I'm not sure if this is the splitter at fault or just my setup as I have a 4K HDMI 2.1 switcher in the front. No big deal for right now and I will address this later on.* Right lights in the front are a little bright but you could use tape to cover it though so it's minor.Overall I will still give this 4 stars as having a stable connection matters to me the most. Having to use multiple splitters was getting ridiculous. It's not perfect but very close. I just wish I could switch outputs and hopefully that would be made CEC work but other then that it's awesome.
