For Pimax’s assistance, here are a list of problems and their proposed solutions compiled from reading different threads across the forums for assistance in improving the quality of the overall experience and quality of future backer and future consumer models.
_________________________________________________
Problem:
Dull colours on the Pimax 5k+ and 8k.
Solution:
Colour, contrast, saturation, brightness control, adjustable by pressing a combination of buttons on the headset, and in pitool.
_________________________________________________
Problem:
Janky configuration each time opening a game adjusting settings. (No Plug’N"Play functionality.)
Solution:
Saving pitool game config settings (FOV, Parallel projection, Brainwarp etc), as in a profile manager for settings for each game in pitool.
_________________________________________________
Problem:
Not clear enough image on the 8k.
Solution:
Sharpening filter akin to the setting in vorpx to improve sharpness on the 8k, or change input signal to 1080p on the 8k to upscale to 4k in the right ratio, as 1440p does not upscale to 4k in a 1:1 ratio.
_________________________________________________
Problem:
Edge peripheral distiortion too high/Large FOV unuseable.
Solution #1:
Better distortion correction profile to make large fov mode useable,and make objects stretch less in peripheral edges of the screens on each eye.
Solution #2:
Sweet spot in the headset rendered to move along with the focal point of the eye (*Maybe achievable using nvidia multi-view rendering or other turing software architechture seen in their whitepapers https://devblogs.nvidia.com/turing-variable-rate-shading-vrworks/ ](https://devblogs.nvidia.com/turing-variable-rate-shading-vrworks/))
_________________________________________________
Problem:
Distortion in general/bad HMD seating/hard to find sweet spot.
Solution #1:
Change IPD amount to correct IPD, Increasing face cushion length to 15mm-20mm decreases distortion - At least two types of face cushion foam (a smaller and a larger, 13mm and 15mm) and deluxe audio strap included with future consumer models.
Solution #2:
A face cushion with a tilt, or thicker foam at the top part of the HMD compared to the bottom,
to reduce distortion as one user modded in this thread https://community.openmr.ai/t/i-get-rid-of-all-issues-with-only-one-simple-mod/12978, or a tilt in the DAS at the top vertical placement of the HMD face cushion foam.
Fix 2: Glue two face cushions together to increase distance and reduce distortion
_________________________________________________
Problem:
SDE on the 5k+ and 8k
Solution:
An optional Anti-SDE screen layer protector, such as the Tech21 iphone screen protector for future 5k+ and 8k consumer models to further reduce SDE, similar to what is offered by Samsung Oddesey+, offering backers the opportunity to send in backer HMDs to be modified and fitted with Anti-SDE technology the same as future consumer models may have.
_________________________________________________
Problem:
Black dots on the 5k+ making SDE appear worse than normal.
Solution:
Possible firmware update solution, or requesting the 5k+ screen manufacturer to fabricate screens custom made to remove the digitizer layer if it be the source of the black dots.
_________________________________________________
Problem:
Cross eyed/eye-strain caused by incorrect IPD measurement from software on screen compared to the actual measurement of IPD of the user, and a discrepancy/latency of software IPD measurement when readjusting the IPD, so that the measurement software indicates to you is a different measurement than what it may have been before if its on the same point you had it before.
(e.g. software reading IPD of 66mm may in fact be 76mm physical IPD at one time, or 72mm physical IPD if readjusted to 66mm software IPD, as the pitool software does not translate the correct measurement when IPD setting on the HMD is adjusted.)
Solution:
Measure IPD on your own, cut a straw to length and place between lenses and adjust IPD until lense centres sit in alignment with the straw.
Open up a game with a starry night sky and stare at a star, adjusting IPD measurement slightly whilst pulling the HMD away from the face until both images of the star you’re focusing on in each screen converge.
Read this thread for detailed fixes for eye strain and how to measure IPD correctly
Pimax, fix pitool’s software IPD measurement algorithm so it gives a correct reading when adjusted and so that it translates the correct software IPD measurement to physical IPD measurement.
_________________________________________________
Problem:
Unergonomic controller design.
Solution:
Offer a controller design without the tracking ring which wraps around the wrists, to avoid them colliding with each other when hands are close together, an improved prototype design with a tracking ring similar to valve knuckles tracking ring.
_________________________________________________
Problem:
Crackling audio coming from headphones
/headphone jack.
Solution:
Try using a different USB port which delivers adequate power, such as at the back of the motherboard or on a powered USB hub.
Failing that, your HMD’s headphones input jack is likely faulty and may require RMA for replacement.
_________________________________________________
Problem:
Bad performance on mid grade GPUs below the GTX 1080ti.
Solution:
45HZ/60HZ Brainwarp to 90hz/120hz.
_________________________________________________
Problem:
HMD plastic housing cracking after delivery, or at delivery, causing light bleed.
Solution:
Sticky tape temporary solution otherwise RMA for replacement.
Assume its caused either by internal force, pressure from its shape or inadequate quality plastic.
(i) Better delivery packaging; and,
(ii) Either alter assembly or HMD plastic housing moulds slightly to allow more space between fittings to reduce the amount of pressure/tension,
(ii) improve the quality of the plastic housing,
(iii) use a silicone/rubber gasket in between the joints to prevent stress forming cracks in future models,
And offering backers the opportunity to send HMDs back to receive upgraded plastic/rubber gaskets if they receive a fault or if they want it, if Pimax decides to use them instead of upgrading plastic.

Problem:
Latency issue with tracking HMD on the 8k / 8k “wobble”.
Solution:
If anyone has a suggestion, suggest it in this thread, the issue is provided in this post for Pimax’s reference.
_________________________________________________
Problem:
Stuck pixel/white pixel/dead pixels
Solution:
Better packaging (thick bubble wrap in between the boxes), better QA before shipment,
RMA for replacement if this fix doesnt work

_________________________________________________
Problem:
Screen flickering / light bleed from backlight/ dots appearing on screen/ differing screen brightnesses/ lcd tear
Solution:
Better quality packaging and cables (thick bubble wrap in between both boxes), better QA before shipment.
RMA for replacement display cable first, then replacement HMD if problem persists.

This poll seems to indicate the dead/stuck pixel issue only affects the 5k+ and is not an issue which affects the majority of owners.
https://community.openmr.ai/t/detailed-poll-for-owners-dead-pixels-8k-5k-black-dots-5k/11960
I made a more detailed poll for the community with respect to the experience backers have had with quality, more input from backers would be useful.
https://community.openmr.ai/t/poll-multiple-choice-polls-to-survey-backers-experience-of-quality/13320
Pimax confimed in another thread where a backer compared two HMDS they received, that parts for plastic housing used in construction may be different, but that hardware is the same, in response to the backer raising the fact the HMD straps on two models he received were different.
@Matthew.Xu, as plastic housing may be different and an anti-sde layer isnt hardware, I suggested that the plastic housing be improved / moulds be changed to allow for more space / rubber gasket be added in between the plastic housing to reduce crack causing tension, and an anti-sde solution be added to design of future backer and consumer release models.
to remove SDE entirely as advertised in the KS campaign, whilst giving backers who want it the opportunity to send the HMD back in to upgrade plastic housing and add anti-sde solution if they want it.
Alternatively, if Pimax decides to sell a HMD with an anti-sde solution to consumers as a different model, backers should still be given the opportunity to receive an upgrade by sending their HMD in for upgrade if they want it.
New proposed naming conventions for new models with anti-sde layer technology:
8K Pro - 5K+ Pro - 8KX Pro (Models with anti-sde layer)
5K BE Pro - 8K BE Pro (Business models with anti-sde layer)
or
8K - 5K+ - 8K+ (TBR) (Standard models - Renaming unreleased 8KX to 8K+)
5K BE - 8K BE - (Business models)
8K X - 5K+ X - 8K+ X (Models with anti-sde layer, X is added)
5K BE X - 8K BE X (Business models with anti-sde layer)
If there’s anything else I’ve missed, post it in the comments and I’ll add it to the list, I didn’t include any ghosting issues as they are reported to be solved on the 8k and the 5k BE and they don’t occur on the 5k+.
