Got my 5k+ since yesterday.
Bit of difficulty to make it work with USB power requirements (none of my native motherboard port would work, had to use a powered hub).
Now working fine, but just wondering… I have a dead pixel, showing blue. Nothing dramatic but still I found it should be interesting to learn about the pixel policy

Given this is a VR headset pretty much any dead or stuck pixels are a problem, especially ones that are stuck on. Anything in the sweet spot is going to be instantly a problem and while peripheral ones might be acceptable they could be a problem if they are in the area where people regularly black out the screen with the narrowed FOV.
There ought to have been a policy published before preorders or with preorders so that people knew what they were getting. Now is definitely the time to full inform their customers on a range of things including actual screen utlisation and pixel depth as well as their RMA policies.

Well it is right around the center of the FOV I must say

A defective pixel is a defective product. Do not give Pimax any reason to consider this will be acceptable, or in other words ‘what ever the market will stand’.

I think there’s another thread somewhere with someone who had to send in pictures of their dead pixels because Pimax would only accept 3 or more as a defect?
It’s not 2010 anymore, It’s been a long time since any dead pixels was acceptable!

Pixels which aren’t stuck on black are not dead, what you have is a stuck pixel.
For stuck pixels, it is sometimes possible to fix them.

I don’t think a dead pixel on a VR headset cannot be fixed the same way as those on an LCD screen
Are you sure it’s a dead pixel? For the longest time, I believed i had a dead pixel on my Vive (after one of my kids knocked it off the table), then I did the lens mod and it turned out to be just dust.
No. Screen is screen. There is as always a chance that you can fix stuck pixels. Not dead of course, but stuck the same way it has been done before.
Yep just, plain bright blue on black backgrounds
If it is by massaging the panel I am not sure it will be that easy on Pimax.
Yea, of course not that one method… but you can use other methods that are software based.

This is the tool Oculus asked DK2 users to run when they had a stuck/dead pixel.

Thanks for the tip! (20 chars)
The tool is from 2006-2007 when the dead/stuck pixels were more common problem. Now it’s 2018, hello Pimax.

There seem to be a rather large number of screens with stuck pixels popping up.
There is obviously a quality issue with the supplied screens.
I hope the screens are not seconds.
I think some extra quality control methods need to be in place, else at this rate, there are going to be a huge number of returns for replacement.
I’ve haven’t experienced a stuck pixel in any of my 3 previous headesets, but I can imagine it would be very annoying & immersion breaking, & I don’t think even 1 stuck pixel is something I could live with in a VR headset.

Have all the headsets with dead pixels been 5k+ ? This might be another reason to go for the 8k .
