Just got my XR and I see a slight difference in brightness and a huge difference in contrast between the left and right eyes. The left eye needs +1 brightness and -5 contrast in PiTool just to be on par with the right eye.
I know there aren’t too many XRs kicking around yet, but anyone else deal with this?
The effect seems to be compensated for by the software with no big visual glitches, so I suspect it’s not actually the panel but a software bug.
I also have issues with different brightness levels on left/right but in my case is a pitool issue. Everytime I turn on my 5K XR, pitool sets my brightness to 1 R and -5 on L so I manually have to change it back.
Mostly this is fixed by hitting the default button. Or else, you could try an older/newer PiTool version and re-write the Firmware again with the DFU.exe. I had this issue right after testing an old PiTool 109 version but the problem was solved when I upgraded to the latest version of PiTool just a moment later.
Yes it seems like a Software bug. I have the same issue with PiTool 22.214.171.124 on my Pimax 5K XR.
In dark scenes the right eye is brighter , it seems like an additional screendoor effect with thousands of pixel glowing while the left side is not affected by this bug.
After going back to PiTool 126.96.36.199 everything was perfect, except for Hellblade VR, the ghosting is back with the older version…
I’m aware of the new PiTool setting the brightness/contrast to non-zero values on startup. That happened with the 5K+ too, and is easily fixed with the default button. I obsessively check all PiTool settings every time I start it up (other stuff like smart smoothing has a tendency to turn itself on too).
The issue with my XR is that even after hitting the default button so that both contrast/display sliders show “0”, there is a very obvious difference between the left and right eye. I need to set huge correction values in PiTool to compensate (and even then not perfectly).
It could be the mura correction, but the sad thing is steam vr removed the option to disable mura correction and even the “black_clamp” option for true blacks is gone now…
I hope that these options come back with further updates on steam.
Have tried restarting headset, service and re-installing the newest PiTool (144), hit default/restore/save many times - no change.
I want to make sure that we’re all talking about the same issue. Do XR owners also see mismatched eyes even though PiTool has contrast/brightness set to zero?
I originally said it can be fully compensated for in software, but with the options in PiTool (integer offsets) it’s impossible to get exactly right. That tells me it isn’t just PiTool numbers that’re off.
