[Replied]Flicking white dots 5K



I’m backer no. 4759 and I received my 5K+ last week in Canada. After hooking it up, I noticed sparkling pixels, like glittering snow flickering all over the display. I tried removing the cable and reseating it many times, but the problem is still there.

The problem looks exactly like that problem from another user: https://www.youtube.com/watch?v=SjjflcvHZYs

I emailed support@pimaxvr.com but no reply yet. I can’t open a support ticket because I get an Error when I try signing up: “Error Signup is not currently available”

I am a preorder guy,…


Attention all with white sparks

My PC had a problem of current leak, felt it when touching the metal parts of my PC case, also my TV acted up when the HDMI from my PC was connected.
Also my TV was showing occasional red flickering on 4K content from PC

Bought a new PSU, no help.
Turned out to be my Logitech G27 wheel was the culprit !
G27 connected to mains + PC = ~110V between the PC case and ground (edit. or between the g27 set + PC atleast)

Disconnected it completely and everything is normal. TV working as it should, havent checked if the red sparks are gone too.

So, to debug the sparky situation, I recommend you to disconnect everything unnecessary from your PC before requesting a new cable. It might also help to ground your PC case.

Edit2. luckily the amperage is something like 0.0002A, take a few digits and I wouldn’t be teasing you guys here.

Awesome Trevor added it to @Davebobman’s wiki.

Good catch might be time to buy those power conditioners for media equipment. :beers::sunglasses::+1::sparkles:


While this (current leak) might be one of the reason for the flickering sparks, obviously the Pimax cable isn’t the best quality. One user apparently had the sparks removed by a good quality extension cable (because of the better insulation in the PC end?)

Edit and yes the high bandwidth content seems to be more prone for the EMI interference. regarding the red sparks on my PC -> TV it was visible only at 4k@60hz.
