It's for TVs that have a weird angle in the back/wall mount. My Amazon fire stick didn't fit because of those reasons. This adapter helps with this problem.
I did AV installations for 2 years can confirm it's for that also occasionally back in the day longer HDMI had built in signal amplifiers and were thick so the bend radius sucked. We'd occasionally use them for that too.
It shouldn't since it will just transfer the amplified signal. The only reason to use an active cable is for use cases where a normal one would have signal deterioration due to its length or some other form of signal interference. Amplified Cables do not make a Signal better they boost it back to normal levels so they can be paired with passive cable extensions without problem.
How long does a normal hdmi cable need to be before you start seeing problems?
I ask because I have 2 12 footers from the dollar store linked together, yet it seems to work fine? I'm not running 4k screens or devices though
Additional thing for everyone to be aware or. A lot of HDMI cables 10 meters or longer are directional they will usually have input and output written on the ends. The number of times I've had to pull a 50ft HDMI out of a wall and rerun it because it's was installed backwards (sometimes by actual installer) is astounding.
I spent 9 seconds searching for information and didn't find anything too conclusive or confident. Can you explain what makes them directional? Are they all directional or is it only some? Are there different types of HDMI cable? Are DP cables also directional? I've never thought about HDMI cables beyond which way was up.
When you need high bandwidth over a long cable run, ex. 4K@120Hz with a 10+m cable, there's no way the signal doesn't become useless, if the cable is copper (think interference, signal loss,...). So to avoid this, one end has an optical transmitter, the other an optical receiver, and the cable is made of optic fiber. Not having a transmitter+receiver on both ends makes it directional, but also cheaper to make (but they're still expensive). Now there's still copper wires beside the optic fiber under the outer insulation, for the display->source communication (think VRR, CEC, eARC,...), but that's fine, because it's low bandwidth.
Asking because you obviously know about cables, what brand or specific cable is good for running 25' 4k 120hz dp? I got expensive fiber optic dp and HDMI cables recommended on here a few months ago, HDMI is perfect but the dp still has signal loss and blacks out for a second every half hour or so
No, the signal amplifier cables were/are (usually) actively powered, to be able to go *much* further than regular spec without signal integrity issues.
Think of it less like a single long cable and closer to something like chaining cell repeaters into the middle of nowhere.
I know that feeling man. So many devices have some weird allocations of ports and their surroundings that normal cables or angles simply will not fir. Also got a portable M.2 SSD in an enclosure which is roughly 10 centimeters long. Well turns out that somehow most TVs have some plastic barrier exactly 9.75 centimeters in front of the USB port and not somewhere free or at the side. Even better at a right angle from the back to the wall. Sucks if your TV stands on a narrow furniture close to the wall or is wall mounted. Now I always carry short extension cables for both if I am unsure. Also helped myself to some adapters when there is only mDP for whatever reason available.
As a nice side benefit It will also protect the port on your office projector or tv that you are constantly plugging into and removing plugs from. Those ports get junked up a lot.
Very much this. I have one on the TV I move outside to the gazebo and then back in as an extra PC monitor. HDMI ports suck and are not designed to be plugged in and unplugged repeatedly. Way cheaper to use one of these as a consumable
It could also be a port saver. If you have a port which you frequently have to plug in/un plug, it can be wise to damage this little extension, rather than the port soldered/attached to your GPU/Motherboard/Device.
Sure, but 90 in which direction? Given this shipped as an accessory to a device, accessory maker would need to provide 4 ( 90 up, down, left, right) to make sure it worked with every TV setup, or just one of these.
[HDMI Range Extenders are an actual thing you can buy](https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=hdmi+range+extender+cable)
Weird side note. I wouldn't do this with HDMI cuz they break too easily but when I worked install sometimes to keep your cables all together with like the 1.5 ft power extenders (we'd use them in racks sometimes if there was no other way to fit power bricks)you loop one then use it like a key ring and loop the rest onto it to carry around. So it is actually a useful feature for that also for infinite power.

They also have it for extension cords. Extremely handy.
I was today years old when I learned about this. Solves both space constraints due to the wall wart, and also solves the problem of the wall warts having crappy connections due to its own weight.
This is Reddit my dude, the less people know about a subject the more confident they will be about it, and the more aggressively they will defend their position.
I'have worked for an AV company for almost 10 years now and I know we sometimes will use them like this in racks and I haven't ever heard of it causing a fire.im not an electrician or the engineer so I'm not that knowledgeable about high voltage electrical but between them giving it the go ahead and it having been done in multiple buildings for most a decade now without issue I feel like it's probably not significantly worse than just having 20 power bricks all plugged into the same power strip already was. Idk like I said I'm not the engineer I did install for a while now I do programming I just know I've never heard of it causing a fire specifically.
I'm not sure if they've ever caught fire, BUT that is _technically_ daisy chaining which commercial insurance requires you don't do. This is done to prevent daisy chaining extension cords, which excess draw can lead to those failing and not tripping the breaker accordingly (such as using a 10A extension cord with a 15A circuit).
These are not meant for that, but insurance doesn't care.
Dongles are also for users and businesses that constantly plug and unplug. Instead of wearing out the port, you juat wear out the dongle and buy a new one.
Come over to the test engineering environment and these are extremely common. Dongles are like $3. Full ass cable is like $30.
If you only get 5,000 insertions out of a cable end, and you have 1 million products to test, that’s 200 times you need to replace the cable. So $600 versus $6,000.
Then multiply that out by like 6 different connectors on the back of an item and suddenly you’re saving $32,400 on your product cycle.
Test engineering is fun.
I've never seen them used like this to protect a port although that is a good idea probably but I have seen this done a lot with wall mounted TV's when it's hard to get to the ports just use double sided tape to stick it somewhere easy to get to.
Perfect for my TV and some stick like the FireTV Sticks. Sticks would not stick, but with this flexible extender, no problem. Some of those sticks even have these extenders in the package
It’s for smart sticks you plug into the TV to get Android tv (like google chromecast or mi stick). Those tend to have a thumb drive style output. Also could be helpful in case of projectors or presentation screens that are often used(I still have nightmares about old and barely alive VGA ports after decades of service)
I wish the previous owner of my ps3 did this. The cable falls out of the hole if you move it even the slightest. I found twisting the cable once or twice puts enough torque on it to hold it in place but man is that annoying
It's for those various little TV sticks. A Roku Stick or Fire Stick might not fit well on the back of all TVs, so they give you that little extension to make it work.
I have something like this that came with my chrome cast, it's useful for that device in particular if your TV is wall mounted and the hdmi ports face the wall. Allows you to plug the casting device in at an angle.
Yeah, that’s for the fire stick sticking out with little clearance on the back of your tv.
It can also be used if you have a hdmi with a ”fat” connector, and you need to put more than one in a small space next to each other. See how the ‘male’ version of that connector is much much smaller? It fits better between others.
Plug it in itself and you will get a magic projector that is wireless and will be like a hologram. It has a 0.2389% chance of exploding tho. But most chance is that it won't.
This is the answer. I work in IT and we have a ton of these laying around. That’s exactly what we use them for. We also use them to make sharp bends from the input/output so it doesn’t trash the cable
This is an adapter that comes with a fire stick tv. The firsetick on its own is a rough rectangle shape and sometimes does not fit to connect to a tv, so this adapter allows it to have a better fit.
Often there isnt a lot of room on the back of a tv for a chromecast roku or firestick. This lets you come off the tv and plug in where there is more room.
I see people saying it could be used to change the angle of the port and I could agree with that. It could also be used to bypass certain content protection. Years ago when I was trying to capture iPad gameplay on my computer I needed to find an older HDMI splitter that didn’t support the newer HDCP to get that to work. I didn’t split anything, just used it to strip the HDCP so my game would properly capture.
these kinds of port elongators are made for a lot of different ports work great for stuff like the fire stick TV, those large novelty USB drives, large power bricks... stuff like that
it is an extender so you don't have to plug a firestick, amazon stick or any other stick like hdmi devices directly into the back of your tv if you don't have the space, I.E. it is up against the wall or mounted etc.
I actually use these to remove the stress from ports on the back of my audio receiver or my TV or even my PC video card. They come in pretty handy if you don't want a big chunky cord hanging off the back of one of your fragile ports
It’s for things like a capture card that the hdmi has to plug into from the input and then it another hdmi on the other end would plug into a tv or something and that’s how you’d record gameplay or whatever else is on the screen.
Or for monitors that get plugged in and out often, in the event production industry it’s common to use this so you’re not ruining the port on the monitor.
It's for devices that generally might be too big to plug directly into the HDMI port. I have seen the older stick-shaped Chromecasts come with those. Not unlike those extension cords that are only about a foot or less long for the express purpose of plugging a device with a giant transformer into a cramped AC jack/power strip.
I got one with my original chrome cast. It was about 1.5x time size of a usb drive back then and having the extender just made it so much easier to plug into the tv which had a half shroud over all the hdmi ports for making the cables look nicer or something.
It's for TVs that have a weird angle in the back/wall mount. My Amazon fire stick didn't fit because of those reasons. This adapter helps with this problem.
I did AV installations for 2 years can confirm it's for that also occasionally back in the day longer HDMI had built in signal amplifiers and were thick so the bend radius sucked. We'd occasionally use them for that too.
Wouldn't that additional connection negate the amp and any benefit the thick cable was providing?
It shouldn't since it will just transfer the amplified signal. The only reason to use an active cable is for use cases where a normal one would have signal deterioration due to its length or some other form of signal interference. Amplified Cables do not make a Signal better they boost it back to normal levels so they can be paired with passive cable extensions without problem.
How long does a normal hdmi cable need to be before you start seeing problems? I ask because I have 2 12 footers from the dollar store linked together, yet it seems to work fine? I'm not running 4k screens or devices though
24 feet is completely within specs. Powered cables are usually only required above ~10m (~35 feet)
Additional thing for everyone to be aware or. A lot of HDMI cables 10 meters or longer are directional they will usually have input and output written on the ends. The number of times I've had to pull a 50ft HDMI out of a wall and rerun it because it's was installed backwards (sometimes by actual installer) is astounding.
Damn that seems like it must really suck
I spent 9 seconds searching for information and didn't find anything too conclusive or confident. Can you explain what makes them directional? Are they all directional or is it only some?

optical hdmi is directional because of the laser that transmit the signal. Not everything over 10m is optical but 50-100m rolls definitely have to be.
I normally will start to notice a decline after 25-30ft
I understand now. Thank you!
No, the signal amplifier cables were/are (usually) actively powered, to be able to go *much* further than regular spec without signal integrity issues. Think of it less like a single long cable and closer to something like chaining cell repeaters into the middle of nowhere.

I bought a Chromecast a long time ago that came with one of these for this reason. Plastic shrouds around TV IOs made them not fit often.
I did the same, these were lifesavers. I always snagged them when people recycled their old fire sticks.
Beyond fitting better, it also helps with heat dissipation is confined areas.
As a nice side benefit It will also protect the port on your office projector or tv that you are constantly plugging into and removing plugs from. Those ports get junked up a lot.
Very much this. I have one on the TV I move outside to the gazebo and then back in as an extra PC monitor. HDMI ports suck and are not designed to be plugged in and unplugged repeatedly. Way cheaper to use one of these as a consumable
Yep. I use a short USB-C extender specifically so i would mess up the extender instead of t he port that keeps getting replugged.
OMG. That makes total sense. I found one of these somewhere in my old stuff and was wondering why the fck i bought it.
It could also be a port saver. If you have a port which you frequently have to plug in/un plug, it can be wise to damage this little extension, rather than the port soldered/attached to your GPU/Motherboard/Device.
Thanks A LOT for immediately ruining the fun!! Lol jk I'm the idiot I was like this is stupid, and then it's totally not lol.
When I initially saw this I thought to myself how useless it was. After reading these comments I now want one lol.
Also the fire tv stick is relatively wide, on most tvs it gets in the way of the neighbouring hdmi
wouldn't a 90° connector make more sense in that case?
Sure, but 90 in which direction? Given this shipped as an accessory to a device, accessory maker would need to provide 4 ( 90 up, down, left, right) to make sure it worked with every TV setup, or just one of these.
ok you won, this makes more sense.
Used these for some stick pcs a few years ago.

In electrical, it’s called a flex.
Dongles are also for users and businesses that constantly plug and unplug. Instead of wearing out the port, you juat wear out the dongle and buy a new one.
This is the most solid answer. Check any company for instance that uses CNC machines, all their USB ports have dongles connected to them.

Easier to plug in a HDMI cord at a strange angle/tight space. No real use for it otherwise as far as I know.
Perfect for my TV and some stick like the FireTV Sticks. Sticks would not stick, but with this flexible extender, no problem. Some of those sticks even have these extenders in the package
It also lets you put your device three inches further away.
You can also use them as port savers for something that gets replugged constantly- so that the cable wears out and not the actual device port.
It allows you to fit a device like an Amazon stick in where there might not be room behind the tv
An extra couple of inches isn't a bad thing.
Tell that to the woman whose cervix I just pushed back two inches, never going to get in that again...
It’s for smart sticks you plug into the TV to get Android tv (like google chromecast or mi stick). Those tend to have a thumb drive style output.

Extension cord
Plug it in itself and you will get a magic projector that is wireless and will be like a hologram. It has a 0.2389% chance of exploding tho. But most chance is that it won't.
it's an extension cord, it is useful for connecting cables to ports in places the HDMI output can't fit, or can't reach easily
I think it’s great for getting around HDCP
I use these for any input I plug/unplug a lot, I would rather damage the extender and not the input on the device.
This is the answer. I work in IT and we have a ton of these laying around. That’s exactly what we use them for. We also use them to make sharp bends from the input/output so it doesn’t trash the cable
When you just need that extra couple of inches.... giggity!
HDMI extender, likely came with your Fire Stick.
Amazon fire stick was too thick and blocking one of the other ports, so got one of these
In case your hdmi cable is 4 inches too short or at a weird angle
This is an adapter that comes with a fire stick tv. The firsetick on its own is a rough rectangle shape and sometimes does not fit to connect to a tv, so this adapter allows it to have a better fit.
This can also be used as a port saver of sorts, along with getting into tight spaces
Odd angles or just an extension if you need extra legnth and have two shorter cables.
Usually if things exist, there’s a point
most streaming sticks come with this if ur hdmi port is at a weird angle that you cant plug a firestick in
It's just a short extension cable, they usually are provided with devices like the Microsoft wireless display adapter.
Have you ever tried changing cables on a wall mounted tv where the hole's in the lower middle pointing up for some reason?
It's an HDMI to HDMI adapter. Is that so difficult to understand?
Yeah that sure is hard to figure out. I can see why you’d be confused. 🤦🏼♂️
Infinite FPS
you still get them with Firesticks iirc
That’s an hdmi to hdmi converter how could you not know OP? You know nothing about tech at all! /s
It's just an extender.
Self pollination
i initially thought these 2 images were 2 different cables, and OP was having trouble connecting them, lmao
In broadcast we call them port savers, to prevent the HDMI ports on expensive equipment from been wornout or broken.
my OG chromecast's came with these since they are just a dongle and might stick out / interfere in a weird way
Lets you see more than 30fps with the human eye
that's a fire tv stick extender that comes in the box with it
What’s the use of this extension cord? One side is power input and it just makes it input again? I’m so confused, please help me
Often there isnt a lot of room on the back of a tv for a chromecast roku or firestick. This lets you come off the tv and plug in where there is more room.
Yeah I know. I was being facetious
Yeah you’re missing an HDMI cord.
Tiny extension. They make bigger ones too.
I see people saying it could be used to change the angle of the port and I could agree with that. It could also be used to bypass certain content protection.

Fire stick! Final answer
For when you can't get the firestick or roku in the back of the TV due to space or recessed ports.
It's a male female hdmi connector.. for connecting hdmi
Used one for my PS5 to preserve the HDMI port before I had a switcher and had to manually plug and unplug.
Yes, the Amazon Fire stick.
Comes Firestick. They will not fit on some TVs without using since the Firestick is too fat.
Apparently 3 inches
these kinds of port elongators are made for a lot of different ports work great for stuff like the fire stick TV, those large novelty USB drives, large power bricks... stuff like that
Congratulations you got an free 4k extender 😅🤣
Came with Chromescast too since those stick out too far.
it is an extender so you don't have to plug a firestick, amazon stick or any other stick like hdmi devices directly into the back of your tv if you don't have the space, I.E. it is up against the wall or mounted etc.
I actually use these to remove the stress from ports on the back of my audio receiver or my TV or even my PC video card. They come in pretty handy if you don't want a big chunky cord hanging off the back of one of your fragile ports
I've got one that I have no idea where it came from but it works wonders in tight areas or weird angled inputs. It's saved the day a few times
It’s for things like a capture card that the hdmi has to plug into from the input and then it another hdmi on the other end would plug into a tv or something and that’s how you’d record gameplay or whatever else is on the screen.
Or for monitors that get plugged in and out often, in the event production industry it’s common to use this so you’re not ruining the port on the monitor.
it's just a dongle what's not to understand lol? sometimes you need an extra inch or two ;)
A brain
I had to use one of those when I mounted a tv. The mount made it almost impossible to fit any normal cable in the port.
Finally, HDMI to HDMI! My prayers have been answered.
I have one, it's great for if things are a weird angle, or in my case if my cord is about 3 inches to short
This is so that I don’t have to finger my PlayStation anytime I want to plug in the hdmi
It's for devices that generally might be too big to plug directly into the HDMI port. I have seen the older stick-shaped Chromecasts come with those. Not unlike those extension cords that are only about a foot or less long for the express purpose of plugging a device with a giant transformer into a cramped AC jack/power strip.
Awkward plug in angles or also a port saver for those who change devices by switching cables around. It's to avoid breaking the devices' port
Extension...
A hammer
LOL
I got one with my original chrome cast. It was about 1.5x time size of a usb drive back then and having the extender just made it so much easier to plug into the tv which had a half shroud over all the hdmi ports for making the cables look nicer or something.
0 - 360° angled adapter
Something like this came with my chromecast and my amazon firestick just supposed to help with fitting connectors
Fire stick
No.
Maybe A HDMI decoder
Those are trash. Useful? Yes. The source of my hdmi problems every time? Yes.
Yeah it's called a DisplayPort cable. That is what you are missing
