Reddit reviews StarTech.com DisplayPort Signal Booster - DisplayPort to DisplayPort Video Signal Amplifier - 4K 60Hz DisplayPort Extender (DPBOOST)

I have been struggling to find a cable extension solution for the PiMax since I got mine last month. I suspect the challenges with the Valve Index will be similar.

​

For the setup in my studio a 45ft extension is ideal. I've had HDMI and USB solved at that distance for years with the Vive and Oculus CV1. DisplayPort seems to be much more finicky, especially at high resolution and refresh rates.

​

So far the only cable I have tried that works consistently with all resolution and refresh rates is this 10ft extension from Cable Matters:

This 15ft Tripp Lite cable does work most of the time, but I have had a few instances where the headset would not initialize on startup trying to run the Large FOV at 90Hz. But when it has intialized it has worked fine:

​

Anything longer than that has not worked for me. Other people have reported success with these Delock extensions at 7.5m and 10m. I was able to get a German vendor to send them to me, and the 7.5m has worked a few times with the small FOV at 60Hz but nothing better than that and I never got the 10m to work at all.

I've also tried active/optical cables with couplers but had no luck at all... I would be totally willing to pay the price for a cable like this if it worked, but in my testing it did not:

​

I even tried this StarTech active signal booster with no luck:

For reference, here is a thread about it on the PiMax forums:

Thanks very much for suggestion,

This worked for us as well.

Here is what we used from Amazon USA:

And since there is enough cord for ceiling mount now:

Total of $175, but closest I can get to wireless for now.

It's not any cheaper, but in case people are interested, StarTech sells a DP Booster box, you might be able to couple it with copper/"cheap" cables:

https://www.startech.com/AV/Extenders/dvi-dp/displayport-booster~DPBOOST

https://www.amazon.com/DisplayPort-Signal-Booster-Video-Amplifier/dp/B01IE3IAIS

I work in consumer electronics, and the box is tunable. However, the practical limitation is probably in the 5m-10m range, and I'm guessing you won't be able to find passive cables in that length anyways... The benefit of buying one of these boxes is if your cable gets damaged, the replacement cable(s) would be cheaper... it'd be a long term cost analysis problem. The other benefit is that this box has switchable settings, so it can even be used with short cables - if you have any signaling problems in general, chances are that it could clean them up.

> What is your IPD?
Personally around 61

> How is the clarity around the edges compared to other headsets?
It's great - in contrast the Rift S I just sent back was awful at the edges. Blurred image with a breaking of the colors between RGB - and it's at more than just the very edge. The Reverb only blurs at the extreme edge (so not an issue)

> Have you played any racing games and can you touch on your experiences with these games. For instance, does the reverb make it significantly easier to look into the distance compared to other headsets? Or is there more improvement necessary in terms of PPI?
Yes, I've been a racing instructor for 10 years so this is really my first love (play more Elite as I run an Elite based Youtube channel now). Yes, it's significantly easier to read your opponents name and car type at about double the distance of the Rift CV1. Now in racing everything is moving so quickly that SDE isn't as big a deal as it is in say a flight sim but it's definitely better. Just more immersive as you're not looking at the cars through a screen door. Does it make you faster, no, as even with a shitty headset you can still judge distances very well.

> Good luck on the cable extension, these things can get tricky, hope it works out well. What are you going to use for your cable extension solution?

It's only a 60Hz (or rated for) but I couldn't find a powered repeater that was any higher. I have a note into HP R&D to see what they are playing with as they are testing some. Since I'm running at 60Hz anyway this may work there (I don't need it for my setup, just testing for you fine folks)

I would like to share that these items have worked for extending the Index on my particular rig:

StarTech Active DisplayPort Repeater : https://smile.amazon.com/gp/product/B01IE3IAIS/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

15' DisplayPort Cable: https://smile.amazon.com/gp/product/B06Y1QP9FV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

15' Active USB 3.0 Cable: https://smile.amazon.com/gp/product/B07C2KWVG1/ref=ppx_yo_dt_b_asin_title_o01_s02?ie=UTF8&psc=1

I doubt it makse a big difference in relation to the DisplayPort, but the video card I am using on this rig: https://smile.amazon.com/gp/product/B07GJKR7RW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I originally tried a 6' male to female DisplayPort extender, but could see 'sparkles' in the HMD. Once I added the active repeater, everything worked great - at 6' and 15'. I used the default adjustment on the repeater.

Outside of the brighter dark areas of the Index vs. other OLED HMDs (have a OG VIVE and Samsung Odyssey +), I absolutely love the Index!

thanks!


i wish we had a 3m cable to test against, instead of the 5m stock cable... i'm wondering how many issues are caused by how far the dp spec is pushed.


i wonder if a dp amplifier would work with the index, and if it would help?

e/a: derp! put the link to a dp amplifier in

Hi, I tried this one: https://www.amazon.fr/gp/product/B01IE3IAIS/ref=ppx_yo_dt_b_asin_image_o02_s00?ie=UTF8&psc=1.

In this configuration, PC => 5m DP cable => repeater => Rifts DP cable(5m).
And no display was coming out, I tried the repeater with a 1.8m cable didn't work too.

Tried with my pc screen worked fine...

What about something like this
StarTech.com DisplayPort Signal Booster - DP Video Signal Amplifier - 4K 60Hz https://www.amazon.com/dp/B01IE3IAIS/ref=cm_sw_r_cp_apa_i_H9D0Cb5QA378B

With a long normal dp cable?

Not cheap but i assume its a solid option.

I use a Vive link extender box for my Odyssey+ so that I can extend my HDMI and USB (and be able to reset my USB by removing the DC power instead of disconnecting the USB cable) so I expect that I would need a Display Port booster like the following for the Reverb:

I was thinking about trying something like this.

DP booster. Anyone have experience with something like that?

I'm guessing for the US, this may work?

You have to go fiber :/ that or an active coupler like this one
