[Replied]Flicking white dots 5K

issue

#162

hello, for 2 weeks there is no answer from pimax on this topic …


#163

try the following … as the first turn on the hmd and then turn on the pc …


#164

Well I remember at one time psu mfgrs used to have Amd &yor Nvidia Certifications.

But yeah like motherboard mfgrs do this with Memory & cpu compat lists Nvidia should do the same.

Especially with this rtx reveal.


#165

Awesome to see more :uk: backers receiving in the forum; hopefully DarkJackal receives soon as well.

You did send Alan the video in his email or your support desk account?

@Scubasteve2365 as you jave jad cable replacement can you post your xp on how this was completed (see Megadonkeyx post)


#167

I can’t speak to how the official process for a replacement cable works because I had one sent to me not through the ticket system.


#168

ferrite chokes didn’t work for me. i tried 4 of them.


#169

Okay after playing a couple of hours with the pimax it got worse…
Now i get red blue and green flickering dots all around the screen, not just white ones!

doh.

was wondering something, my hardware is as follows:

ryzen 1700x
asus prime x370 pro
2933mhz ram using d.o.c.p

one thing i was wondering was could the fairly high frequency ram be causing some large amount of emi? although this ram is running at its advertised speed.

nothing on this machine is overclocked.

maybe it is just a bad cable.


#171

i have ddr3 ram @1600mhz… so it is not the ram
i think, without opening anything, the adapter displayport/usb/dc input to hdmi connector has a bad soldering joint / bad connection.

the QA team has clearly not tested every delivered cable plugged in with the hmd -> maybe just the hmd @ test stand with a fixed test cable ?
And after testing the hmd they took a hmd cable out of a big box plugged it in and shipped it …
just guessing…


#172

It’s actually shown in a YouTube video that Margie did. It’s exactly like that… :upside_down_face:


#173

Probably bad cable as mine is 3600mhz

Hi,

I received my headset today in France, a 5K+ model P2. Same white dot flickering issue, in dark (well gray, because there is no dark :confused:) environnement.
I can see that it is very common, and there is no response from Pimax.
Support website is not working well and i cannot create an account to open a ticket…

Maybe try a different browser as some can login/create account. Added Dallas to your post.

Are you a backer or pre order?


#176

They deactivated account creation. Only option is to email support


#177

I am backer #5393. Do we finally know if the white dot issue is a software or hardware issue?
I tried restart, unplug/plug,change display port…
It sometimes work for few minutes and then dots reappears…


#178

Thanks.
What is the best mail address to contact them?


#179

Support@pimaxvr.com

I got a response from alan after that.


#180

Thanks, i ll try that. Hope it can be fixed with not a full HMD replacement


#181

This seems to be a potential cable issue. Check the troubleshooting wiki in the 5k 8k directory in banner as some had luck with fixes.
