Hi folks
I'm sick of HDMI cables and as I don't do gaming I don't care if there's a tiny bit of lagging but do these HDMI transmitters and receivers work OK -- this really would help me to get rid of a load of HDMI cables for 4 screens.

Googling a bit showed range is approx 50 metres -- more than enough -- for these devices but the price range is huge -- so anybody with experience of using these please post. I need 2X at 4K UHD and 2X at standard full HD (1080 X 1920) so 4 devices.


Cheers

Hi folks
Got these at €7.50 per set (Rx and TX) -- got 3 of them -- cleared a whole load of messy clunky bits of HDMI cables == these are even better when the TX (Transmitter) is plugged in to HDMI ports on a Mini PC.

So that's a successful test of Box 1 which now can be totally removed from my desktop -- no HDMI cables needed for that box.

Note though you need to have a powered usb box 5V (any old phone charger type thing will do), or charging port on PC - unless your HDMI is sufficiently self powered

About to replace my 2nd NAS with a Mini PC so I've ordered another 2 of these -- so total outlay 3 X €7.50 -- €22.50 !!! and to clear a whole slew of messy thick HDMI cables !!!!!

Note though -- I had to "Pair" the device on Windows first -- then re-booting into Linux it was fine -- that's probably something to do with the blu tooth functionality on a Linux distro rather than any inherent problems with the device.

There are other devices out there which are self powered etc -- a bit more pricey -- I went for the "El cheapo" version to test the principle for stability, functionality and to see if the devices can run for hours without overheating. I might later go for those options.

So far a great idea for those who don't want messy cables all over the place - especiallt thicj HDMI cables for 4K UHD montors.

Marking as solved -- happy with the outcome especially for such a low price (an individual HDMI cable can cost almost that much these days !!!!).


Added : HDMI sound works too without any problems -- no jitter or lag.

I have 6 monitors. If I game, I only use one dedicated monitor. There is a plausible advantage to these. I have only briefly looked at them since you posted this, previously I knew nothing about them.

I have a neat cable setup but it would still be nicer having 1 cable (for gaming) as apposed to 6 cables in total.
Until I update my monitors, my only concern is that I currently need special HDMI to Display Port cables to make the video card and monitors respond to each other.

Hi there

(Tx=Transmitter and Rx receiver in this post) !!.

@antspants

Works also if you connect the display port to HDMI e.g computer->display port>HDMI>Tx etc -- but if you do that you'll still need an HDMI connection for the Rx at the monitor end -- maybe it would work with another HDMI->display port at the monitor end - provided the HDMI is bi-directional i.e both input and output signals accepted as the computer has outbound HDMI and the monitor obviously needs an inbound signal.

I've just tested it with a computer having a display port as its GPU so : ->display port ->HDMI->Tx->Rx->HDMI port on monitor Most monitors have HDMI ports -- not sure what would happen if the Rx is connected to the HDMI end of an HDMI-> display port connector which goes into the device -- you are on your own on that set up !!!.

The range of these - even for the el cheapo model is further than the range of wireless keyboard and mouse so the advantage is you can have access to your computer anywhere you have a screen with the Rx (Receiver) plugged into its HDMI port without ANY cabling -- just a small USB 5V power supply (and a lot of modern TV's have a 5V powered port anyway so you might not even need the power supply.

The spec implies max range of around 50 metres - but that depends on your building etc. Also being RFCOMM Blu Tooth powered instead of infra red you don't need the Tx and Rx to be in visible site of each other which is a problem with some TV remotes of course.

Not sure why this type of device isn't more known about -- especially as loads more people are using Mini PC's where 3 thick HDMI cables however neatly you have the cables is still awkward and of course it means your computer is tethered to a monitor via a cable.

I only thought about these when I was reading about Intel's wireless display -- that's another who;e area of complication -- seems the HDMI Rx and Tx pair is by far the better solution -- not much info around though on these -- and as I'm not a gamer have no idea if this type of device is suitable -- no trouble though with 4k UHD monitors.

I'm 100% happy with my initial testing of this device -- the original aim was to replace 2 aging HP proliant gen 8 server machines I'm using for NAS boxes with 2X mini PC's. So far so good -- one box already on its way to the tip -- far too old to be of any use to give away. !!!

Certainly reads like something I’m interested in. Im not that great with cables but I know I had to get non bidirectional cables video card Display Port —> Hdmi monitor.
The first bidirectional cables that I spent decent money on didn’t work, because I didn’t do my homework.

Thanks for posting, jimbo45

Glad some of it made sense and great to get feedback.

Always enjoy reading your stuff even though from me you are at the other end of the planet. !!! Don't worry about Govt's etc -- 'OZ doesn't have a monopoly of poor govt and biased / corrupt politicians --it's probably par for the course -- no better / worse than a lot of other places -- your nearest neighbour NZ seems to be getting much more like a real "People's republic" --If I tried driving a car there I'd be either jailed or fined $NZ 1200 within the ist 5 mins !!!! judging by that reality TV show "Motorway Cops NZ" (yes we get that rubbish here too !!!!).

I haven’t watched commercial television for over 5 years. Even before that only ever the news. I get a bit irate at anything bull💩

If I tried driving a car there I'd be either jailed or fined $NZ 1200 within the ist 5 mins
I thought the same about the USA but after playing GTA5 for over 600hours, I think driving on the right hand side is embedded in my brain.
