Yeah the language barrier was so great that Pimax didn’t respond to their input at all. The beauty of the M1 and the last minute distortion profile update.
But I think we are done here, you win.
I guess none of the suggestions by your account made it into the m2. But yes we all know about the distortion profile in the m1 was not ready with the new lenses as detailed by the leaks.
Right, sorry for my stupid musings. If we made a timeline for all the 2018 Pimax events, we’d see success after success.
I also apologize for making claims all the time and coming up short, maybe I should add another apology thread, we seem to have them in around 12 month intervals, why not break that habit. I won’t lie again, I promise.

Yesterday I noticed the dots on my freshly arrived 5K+ as well, as soon as I put my glasses on! I am not sure whether I want a replacement, even if Pimax will eventually offer one. They are noticeable from time to time and kind of annoying in the same way as SDE. I think Pimax should get rid of them if possible and offer replacements for those who desire.

Could you look at this video and tell us if your headset is similar to the second or the first headset received by tyriel
Black dots on my 5k+ arrived today. Is this a backer bonus for me? Also sparkling white dots.

Yes, you’ll be named backer of the week! Sorry for your bad luck and pulling your leg but it doesn’t look good. You should also inspect the display for dead pixels and cracks in the housing.
If reseating the cable doesn’t help with the sparkling, ask for a replacement cable.

sparkling white dots is because of the cheap cable they are using,
If you got the black dots you need a replacement…ANd hope you get a good one…its a lottery

For the sparkling dots file a support ticket.
If the sparkling isn’t fixable or hsve dead stuck pixels you will qualify for a replscement.
@anon74848233 please add to earlybackers
But overall, I liked it!
As an experienced mechanical engineer i could see some improvements.

How do i check for dead pixels? Should i really try to see these?

If you have Virtual Desktop try something like this. I also remember that somebody posted a suitable video to play on youtube that makes the detection easier, but can’t find it. There are other methods too.

There seems to be two types of “dead pixels” and then there are the famous “black dots”. I have all three of them:
-
Real “dead” or “stuck” pixel. Dead = black, never lit. Stuck = keeps shining regardless what you want it to display. This condition can affect the whole pixel (i.e. red, green, and blue subpixels) or just one or two subpixels from one pixel.
The easiest way to spot one is to make your panel to display one base color (either red, or green, or blue) and look for black dots. Using uniform base color makes even subpixels visible. At least in theory, because here you are also facing the lenses, which deform and distort the image, so some dead (sub)pixels in some remote areas of the panel may go unnoticed without disassembling the headset. -
Dust particle on the panel. It produces bigger than pixel and non-aligned defect spanning over more than one pixel. For detecting that, you are better using white color on the panel, so you have as much light as possible.
-
“Black dots” is the uniform pattern of black dots (which are in fact pixels with reduced intensity) which is visible anywhere on the panel (you can find quite a few shots here on the forum). This should be easily visible on red/purple/skin color (or anything with red/blue mix).
For observing any of those the uniform color is the best because you do not get distracted by the head movement and the moving environment.
If you want to test it, you can use the testing images I posted here: https://imgur.com/a/5tyR2jT
To get this image displayed in the Pimax you should get your headset connected and powered. Then you need to:
-
copy the image of your choice into
C:\Program Files\Pimax\Runtime\resourceor your equivalent and rename it topimax_default.jpg(save the original one so you can put it back once you are done with your tests) -
restart
PiServiceLauncher.exeservice (e.g. by using Task Manager → Services (tab))
You do not need to run PiTool, or SteamVR for that. Once you restart the service, it will reinitialize the headset with the new image and you will see it in it. Then rinse & repeat for the other one. After some tests I figured out that this is probably the easiest method to ensure the consistent and uniform color.
