Extending usb and hdmi cable length


I have read a couple of post and am putting together a solution based on them. I’ll probably screw it up anyway but just want to know in advance if this has a chance of working.

  1. Active hdmi cable 30 ft 4k at 60hz. Here is the link.

I plan on using a 4k compliant coupler into the pimax 4k.

  1. USB repeater 2.0 that uses Ethernet cables to bridge the usb connectors. Plan on using a 30 ft Ethernet cable if I can find one. Here is a link.

So, what did I do wrong in advance? Should I expect any loss of quality in the display? Thanks.

Pimax 4K headset not recognized in piplay

I have this device:
cable lengths without additional power supply of about 10 meters
possibly with additional power and you can do more but everything here is limited by the quality of the cable.


I saw this on ebay It supports 4k at 60hz with no power up to 82 feet. Can this be right? https://www.amazon.com/J-Tech-Digital-Connecter-Passthrough-Bandwidth/dp/B01HQQHOB8/ref=sr_1_3?s=electronics&ie=UTF8&qid=1516216780&sr=1-3&keywords=hdmi+repeater+4k+60hz


I can not say anything about your module since it’s just another Chinese clone and how they work I do not know!
I gave a link to the product that I have and I know for sure that it works with a pimax.
I showed him the transfer at a resolution of 2.5k to 8 meters without
additional power supply with 2 cables 3 meters (hdmi 2.0) + 5 meters
(hdmi 2.0)


Update for those doing research. I got it to work with 50 ft cables. Here is what I used with my pc running a 1080 ti and i9 processor.

I made sure every component could run 4k at 60 hz which includes the repeater. You can daisy chain fiber cables with another 50 as long as you have a repeater. The usb 3 cable came with a power supply which helps power the headset. If you don’t plug it in it will not work. So there you go. All I need are padded walls and health insurance. lol


Does this set up replace the original 1.4dp and power cable that comes with the pimax ? i received the 8k but the pins were bent. Can you provide cheap links to a cable (s) that can replace the one that was broken ? It might be ages before pimax send me out a replacement, Im not interested in a long cable… just t replace as close as possible the original one.

Thank you in advance.


The pimax 4k cable was not removable. This post was about extending hdmi & usb cables using a repeater or 2.

The 5k+ & 8k use a propietary cable connector on the hmd that is removable.


where can I get it
the cable for pimax4k usb and hdmi new
what a broken sinche and I ran out of hdmi


If you mean a replacement cable for P4k?

Have found it before online. If memory serves it was a micro Usb inside tge headset. Was it a mini hdmi inside or regular?


inside the helmet is micro usb and normal hdmi
inside the helmet

and outside the helmet
outside usb is normal standard
and normal hdmi
and outside the helmet


I will try to still find. Having trouble finding correct words.

Alternatively you could run 2 cables out with mild mod.

@Doman.Chen can you help with locating a p4k replacement cable?
