cenmate4K@60Hz 4:4:4 HDMI Extender Over Single Cat5e/Cat6/Cat 7, Up to 230Ft (1080P), 164FT(4K), HDMI Over Ethernet, Supports Bidirectional IR, 3D, HDCP, EDID, POC

Great product for the price

I ordered this kit with the intention of connecting a TV in one room to a computer in a different part of the house. The distance between my source device and the TV I wanted to use is way too far for a regular HDMI cable, so I would have needed to spend more money on something like a fiber optic HDMI cable. Going with this HDMI over Cat 5e setup gave me the flexibility of reusing an existing run of Cat 5e cable.There are two separate units in the box. One is the transmitter (connects to your source device) and the other is a receiver (connects to your remote display). Also in the box is a single 12V DC power supply (not 5V like the product listing says), an IR receiver and an IR blaster. From my understanding the DC power supply can be connected to either unit, but I haven't tested whether that is true or not. In my case I have the power supply connected to the transmitter unit, and power is sent through the Cat 5e cable to power the receiver unit as well. The transmitter has two HDMI ports, one of which serves as a passthrough to connect a local display. The receiver only has one HDMI port.My initial test of this product involved connecting a portable monitor with an HDMI input to the receiver and connecting the transmitter to a PC through a short HDMI cable. It's probably not relevant, but the PC I've been using for this has an Nvidia RTX 2070 graphics card installed, though this shouldn't make any difference. I then connected the extenders through an ordinary Cat 5e cable that was roughly 10 ft. long. The monitor connected instantly, but the resolution was incorrect. This is probably my fault since I connected the transmitter first, but it wasn't a big deal. The setup worked, and it seemed perfectly stable.I then connected the receiver to the remote display I wanted to use. This time I was using a much longer Cat 5e cable and the display connected perfectly at the correct resolution. This display is a 4K display, and I had no issues getting a 4K60 signal over this distance. I haven't tested the IR blaster setup since I don't have a need for that with a PC, but I have to imagine it works just fine. I'm pretty impressed by this product. I haven't messed around with extending video signals over long distances much in a long time (the last product I personally used was for VGA), so I didn't know what to expect when dealing with HDMI. I was pleasantly surprised at how it just worked right out of the box.

I am using this extender to replace an older extender from a second zone on a Yamaha receiver to a kitchen in a different part of the home. It seems to be sensitive to the signal fed to the Transmitter and can intermittently shut off signal temporarily to the far end Receiver. Using a top Yamaha receiver, I can send a Roku signal to the kitchen and it works great. However, if I use the same Yamaha receiver and send a Pandora signal to the kitchen, it will intermittently shut down for about 5 seconds and then come back on. This happens over and over about 3 to 4 minutes between outages. Really strange! I though at first that it was the power supply in the kitchen TV that was going out. After a bit of troubleshooting, I've narrowed it down to the extender. It seems to be a difference in the signal between Pandora (which is built into the Yamaha receiver) and the Roku (which is an HDMI input on the Yamaha) creating the issue. The original extender that this one is replacing had no problem with Pandora from the Yamaha receiver so I'm not sure what to think. I have gotten around this issue by using Pandora on the Roku instead of using the Pandora on the Yamaha receiver. Other than that, it works great. I do really like the Loop Out to a local TV - that works great - even though I'm using a 4K TV in the kitchen and a 1080P TV connected to the Loop Out - very nice! The quality of video and the audio is excellent and it is really just 'plug-and-play' as long as you have a good Ethernet cable from the Transmitter to the Receiver end - with good connections!

I've had 1080p ethernet HDMI extenders before to bring video out to my detached garage where my office is located. I use it together with a splitter so that I can watch whatever is on TV that the family is watching in the main entertainment area of the house. Now that we upgraded our home setup to 4k, I needed to do 4k out to the detached garage as well. This has been working well so far and we love 4k! The units feel very study compared to the old one and I appreciate the mounting bracket. I was able to mount it to the bottom of the desk with no issues. Probably the best HDMI extender I've seen.

This did exactly what I needed it to do, which is split the signal between two rooms for a football game. The only thing is that it only transmit stereo audio, so if you have surround sound it wont work.

Maybe I got a bad one, maybe not?The video over ethernet worked, but the hdmi loop out did not work on the unit I purchased.

I’m an AV dealerNeeded a HDMI Extender and splitter to show one source to 2 TV’s for a businessIt worked right awayHopefully it stays working

I use this hdmi extender to send the display of a kiosk computer to the common area of an industrial environment. The distance is over 100ft and this setup works perfectly.

There are lots of cases where you can run an ethernet cable, but not an HDMI cable. A network cable can route through much smaller holes/cavities and can be terminated after it has been run. Also, distance can be a limiting factor for HDMI compared to ethernet. I'll be using this to run HDMI over ethernet from one room in the house, up through the loft and down in to another. An optical HDMI cable may have been able to handle this, but would have been much more intrusive in terms of drilling bigger holes etc. I haven't installed this extender yet, but have tested with a longer length of cable than I'll be using on the permanent run.There are two components to this - a transmitter (with an optional IR blaster) and a receiver (with an optional IR receiver). Both components have a 12V power input (the listing states 5V but it is 12V as per the diagrams) - but the PSU for the transmitter can power both ends. This is handy if you are using the receiver in a garden for example.Set-up is pretty much plug-and-play. I'm using a good quality CAT7 40m cable, which is probably overkill but won't hurt - I'd recommend using high quality ethernet and HDMI cables. I have no problems using the extender in my set-up. I'm transmitting from a Roku Ultra at 4K/50Hz and the picture at the receiving end is identical (to my eyes) as the original. I'm only running stereo audio, but according the manual it supports most multi-channel formats which is good to know.The infrared remote extender works fine and there is no noticeable lag with either the remote or the picture/audio. The HDMI loop-through at the Transmitter end is very useful, as it avoids having to use an HDMI splitter. It works fine (again no lag), but doesn't work passively. This means that if you use the HDMI passthrough, you'll need to have the transmitter powered up even if you are not using the extender function. If that is likely to be a common situation than a (low power) HDMI splitter may be a better bet than using the loop-through.I've used a plastic 1080p extender in the past, which worked fine. This set-up feels much more substantial and sturdy. Both ends are wall-mountable (or can be mounted on or under a desk for example). It is reassuring that the manufacturer's website it professional looking and there is plenty of information about this product there (search for model HD50POC-4K60)).

This pair of HDMI extenders are a couple of small metal boxes that look and feel really nice quality. They come well packaged in a nice box. You get one mains adapter, as only one of the boxes needs a power source as the other is powered over the ethernet cable.You also get a couple of IR blasters that I didn't need to use.Basically, it's pretty quick and easy to get working and I found the results were excellent.

The build quality of these two boxes is good, and all ports are clearly labelled. A 12V power supply is included, along with an IR receiver and transmitter, that should allow you to control a device, such as a DVD player, in a remote location. It uses PoE (power over Ethernet)1, so copper Ethernet cables are preferable to CCA (copper coated aluminium), especially over longer distances.I tested this HDMI Extender, using a 10 metre Cat 6 Ethernet cable, connecting from a laptop in my kitchen, to the 4K TV in my lounge. The only way that I could get it to work reliably, was to provide power at the receiver end. and use it with my laptop, set to ‘duplicate displays’. I wasn’t able to monitor the output by connecting the ‘HDMI OUT’ to the HD TV in my kitchen, even though the TV detected that it was connected to a source.So yes, it does work, and would be fine for duplicating output (perhaps via an HDMI splitter), to a monitor/TV or projector, in a remote location.

This HDMI extender is great. It sends clear 4K video over a long distance with no delay. Setting it up was simple, and the bidirectional IR makes controlling devices easy. The picture quality is sharp, and the POC feature saves hassle with extra power. Great product for anyone needing to extend their HDMI signal.

I got these to send video/audio from my home office PC to the main living room TV. I already have a spare Cat 7 cable between the rooms, so it made sense to use this instead of running a new (expensive) long (20mtrs approx) Fibre HDMI cable, as I don't need anything more than 4K60Hz. The sender/receiver are good quality, really well built - metal casings, and can be mounted to a wall if you wish, but I've just left them behind furniture. An IR repeater is included and works very well.Overall, after a few weeks of use, it works perfectly and I've had no issues at all.
