PSA: Turn your Pimax off when not in use... Possible screen burn in issue!?

Pimax 8K Series
1

I had a play last night and noticed in dark scenes that I can see the pimax logo appear to be residual on the screen!!

The logo is what you see when you don’t have anything running and have pimax VR home unchecked (usually due to it heavily using GPU when you’re not even using it!).

I don’t know yet if the effect is temporary or permanent?

But I can confirm the headset has not been turning itself off/going to standby when not in use and so most of the time I’ve manually done it, it’s not through that much use the perceived burn-in has occurred.

For now, I highly recommend for everyone to manually turning off the HMD when not in use.

Pimax. Can you look at this with some urgency, please? A static white logo is clearly a bad idea and the lack of proximity sensor along with whatever the current solution is supposed to be doesn’t work! or at least doesn’t for me so likely will affect others too in time!

Have to search forum here. But it would be temporary as lcd apparently don’t perm burnin.

If you look in your pitool folder there should be a pic of the logo. Just replace it with a blank image.

Hopefully they will give option to use animate gif file (might work)

But yes concerning your headset is not defaulting standby via sensors. Is there a subwoofer or something causing just enough vibration maybe keeping it from sleeping?

If you haven’t test on a foam or rubber mat.

No known vibration source, HMD just sat there for a while without turning off. Noticed this a couple of times.

Good if not permanent damage, but still a problem even if temporary.

I can see the logo at the following path:
“C:\Program Files\Pimax\Runtime\resource\pimax_default.jpg”

I’ll replace that thanks! But pimax need to look into all of this.

The standby is working again, although only the image goes off, not the backlight as we know making it harder to know if its in standby or not. I hope they can get standby powering all off properly and they look to improve on that background image to prevent the burn in effect, even if its temporary its going to be visible a lot for many people.

I hear you there. No one wants to go through a fix or wait for it to disappear.

For the record, specifically how do you turn off the Pimax 5K+ to insure it’s not inadvertently left on?

I usually power iff vua switch & unplug power & usb (well truthfully full disconnect) but more a cat precaution. :confused::wink::+1:

If your device is PiMax 4K and the screen will disconnected when you don’t use it.
If your device is PiMax 5K Plus or 8K,Gyro Sensor will make screen disconncted after 1minutes When you stop using headset

As for heavily using GPU,
PiMax Logo picture just like wallpaper of desktop and only take a slim GPU.
If you can see fire or burning on the screen which means your pimax vr home task still runing and using GPU heavily.You can shutdown the pimax vr home and this problem solved

Hold down the power button on the top for a couple of seconds or so.

The whole hmd will go off

Yes the GPU usage is what I was referring to for home (which ideally you should get to pause when no activity detected!), hence some of us already disable that and use the static wallpaper (bright white pimax logo on dark background). However that wallpaper is causing burn in! which even if temporary its happening and noticeable.

Too bad Pimax didn’t think to add a proximity sensor like most of the other VR headset manufacturers did. That would have eliminated this issue entirely.

I agree to a point. If they ensure the gyro sensor works well then fine no need for the proximity sensor. I actually think they need to change the pimax logo screen though, its the worst static image to have!

At least I know we can do this ourselves now, but I’m still suggesting they look at doing this by default.

I see that this was discussed a while ago. After making my own thread about that, I wonder why is it still not addressed?

Good question. It may not be as much of an issue on lcd. But oled it’s a killer.

I dont have the latest version of pitool but this issue has evolved since i got my pimax a couple of months back.

Initially the backlight would turn off when the HMD was put down but the LCD panel would still be on and the backlight would not turn back on every times.

A version or two ago of pitool it switched to blanking out the panel, no idea if it is actually on and “displaying black” or off but the backlight never turns off, at least with the second newest pitool/firmware.

IIRC this blanking only happens when the HMD is actually displaying vr content, if its just set down and no VR app is running the regular pimax text and logo are displayed.

It is definitely an issue of LCD, they say panels dont “burn in” like CRTs but they absolutely do, its to a lesser extent and the crystals in the affected areas can be “massaged” back into regular working order by cycling them but that isnt instantaneous or a 100% sure thing.

It’s not the problem it is with Oled. Prevention is best & yes it is not quick to fix LCD.

All Pimax had to do was leave the proximity sensor in place that the review units had. They promised us that the review units would be identical to the ones we would receive. But then they eliminated the sensor from every HMD they shipped to backers and customers in order to save pennies on each unit. Now the lack of a proximity sensor is causing issues with OLED, with people watching movies, etc.

Thanks for lying to us, Pimax! How did that work out for you?

Hi,

maybe Pimax could incorporate an adjustable timer in PiTool so folks could select if and after what time he hmd would switch to standby or off.
