I've got a fairly complicated entertainment set up.I've got a monitor and a TV, and I've got an HDMI switch with three game consoles connected to it: the Xbox 360, the PlayStation 3 and the Nintendo Switch. (I've also got an Xbox One X which I use as set top box, which will have to go to a new HDMI switch as my TV only has two HDMI inputs. Neither here nor there for this product :) )Occasionally I may have the desire to play games on the smaller computer monitor so I can parse the interactive content more easily without it giving me a headache, me being autistic and everything :-) but then I may have the desire to watch Blu-rays and DVDs on my PS3 and Xbox 360 respectively, on my larger TV.You probably know that physically changing connections out too often can wear out the connectors; this is no different with HDMI! So I wish to preserve my connectors as much as possible, and this product that I am reviewing now by avedio links definitely helps out in that regard.Installation couldn't be simpler! I just plug the HDMI out of my HDMI switch into the input of this "one in, two out" splitter - then connect my computer monitor with a rare HDMI input into the first HDMI out of the splitter, and the TV into the second HDMI out of the splitter! (The default input of the monitor, that my computer generates, is a DVI-D, but that's neither here nor there for this device :-) )So, the colors are strong, the audio is nice and loud - as though I were passing a straight HDMI signal through! And there's really no lag to speak of - but when both my outputs are on the same time, there is a TINY, less than 1/10 of a second lag between the devices, enough that I can hear it but not see it, and I can't tell which device is behind. But I don't see a scenario where I have both outputs on at the same time for a long time, anyway.Good show, avedio links! I'll be getting another to go with my secondary monitor when I get a new games console to hook up to it within the next couple weeks or so. I'll report back if, as has happened tragically to a few of my fellow reviewers, the device should fail in a few months. But I doubt it will - seems well-made. Just remember to provide power - get a USB AC Wall Adapter at the same time, so the splitter can pump the signal to both of your outputs as seamlessly as possible!PS(3)!!! :) When using this splitter and when playing Blu-rays on the PS3, I think the automatic frequency detection gets a little wonky - so my monitor by default displayed an Out of Range error when I got into the video content. So, I just went into Settings -> Video Settings -> 1080p 24Hz Output (HDMI) -> Change it from Automatic to Off. There should be no other ill effects from playing it either on the monitor or TV going forward. (I also changed the BD/DVD Video Output Format (HDMI) from Automatic to RGB, which I think is superfluous as the other option has to do with Component output which this splitter of course doesn't do :) )

I used this product with my Karaoke player to output HDMI video with this splitter to feed my monitor on stage, as well as hook up to the two wall mounted monitors in the ballroom, so the audience can see the words on screen also.The unit works great, is small, compact, and easy to hook up, and comes with all adapters and cables you need.I would recommend this product to anyone who needs to view HDMI video on two or more screens.

This product was good, but it didn't actually have the function that I needed, so I'm returning it. I'm docking 1 star not because the quality is poor, but I feel like HDMI splitters should all be able to not just split one screen to be mirrored, but also to extend. Maybe (/obviously) that's all in the tech that's inside, but it seems like why doesn't it do both?It's fully on me that I didn't read that part of the description though, and it's a great product. It worked immediately and the picture was clear. It's just not multifunctional, so be sure that it'll work for your needs

Needed something to mirror my laptop to my tv. This works perfectly.

I have this splitting a directv signal so I can mirror a tv in the kitchen with the LR TV. I have purchased another brand of splitter twice that worked flawlessly but only lasted a little over a year. I thought I would try this one to see if it lasted longer. Hook up was easy. It worked as intended for the first couple days. Now every time I turn the TVs I have to unplug the HDMI cast device to rest it the splitter. While watching the kitchen screen the picture will go black at random times and stay black for a few seconds before the picture reappears.

In 2nd day of use so far. Just as a first use trial, I had first HDMI cable OUT going to an HP Compaq 2105tm monitor and 2nd HDMI cable OUT going to an Elgato CamLink HDMI plugged into a Windows 10 PC running OBS Software. It all worked initially. Didn't need to install any drivers or anything. For the monitor the onscreen signal appeared literally instantaneously. For the cable going to the Elgato CamLink HDMI Windows 10 PC there was a little delay at first, and I think it was while the device setup was being recognized by windows and the driver(s) were being auto-installed. It was just a few seconds. No problem. I thought everything was fine. While I made some settings adjustments to my camera & scene I noticed one of the monitors wasn't displaying anymore. I unplugged then re-plugged the HDMI cables. Nothing. I repeated but switched swapping which cable went into which HDMI port on the splitter. That worked. Fine. For awhile. Then the signal stopped. Again. This happened 3 or 4 times over a span of about an hour and a half. And then.... the output signal to direct-to-monitor would not produce signal displayed onscreen, regardless of unplugging and replugging, switching swapping cables, rebooting PC, turning monitor(s) off & restarting, etc, etc... I tried everything I could possibly conceive of. I have no idea why it was the cable leading direct to the monitor & not the one leading to the OBS Elgato CamLink HDMI that was being so stubborn. If you ask me, my logic tells me that THAT's the one that seems like it would be the more stable and stronger and of all things SIMPLER connection of the two since it was just a straight shot, a direct route, no multiple layers or levels of devices & technologies etc etc.... but that's not how it turned out. INSTEAD, despite all of that, after 2 or 3 HOURS of troubleshooting this dilemna, the Elgato CamLink -to- OBS HDMI-passthru held up its end of the deal come hell or highwater that much I do know. By the way, I have (3) three of the HP Compaq 2105tm monitors, and I so also tried swapping out from the original one to one of the others to try to tweak or reset the firmware of the switcher or whatever, etc etc..Same Result. Ineffective. I have an LG 4K newer monitor with another PC system setup elsewhere that I DID NOT try this on yet. It's larger and not as portable as the others and, frankly, it's reserved for other usage and was not intended to be moved/transported for this purpose. So I hadn't tried it yet as that would involve a lot of disconnecting/unplugging, & lugging from/to etc etc...I just hadn't escalated to that final resort option, and actually don't look forward to it, I shouldn't have to IMHO.So, that's my review :: 3 STARS :: I can't say it didn't work, at all. It did. And the output was very good too. The signal was same as previous direct single cable signal, indistinguishable as far as I can recall.Obviously, your results may and probably will vary from mine, since was using a scheme more involved than simply splitting a signal in the more usual typical mainstream output way it goes.
