Here comes a new update of Pimax VR Experience v0.74.0.0!

Setup Instructions :

  1. Download and install PiToolSetup_1.0.2.087_V2.0
    - Note: Pitool V. works with this version of PE as well, but to get Backlight brightness sliders working, you need to use PiTool

  3. After installation when PiTool is running, make sure to tick the checkbox “Start Pimax VR Home” (located in PiTool, Settings > General). This will automatically launch the Pimax VR Experience.

This version of the software introduces a bunch of new features and updates making it fully compatible with all functionality of PiTool Backlight brightness for all Pimax VR headsets, including 8KX, is now instantly adjustable in the UI with the use of slider and +/- buttons, no HMD reboot required.

A new calibration menu has been added with selectable test charts/images and instant access to all adjustments, made to conveniently customize HMD backlight/brightness/contrast/individual RGB color gamma for each existing profile, and save the changes instantly. Background is automatically set to black/none while inside the Calibration, for optimal conditions. The feature can be accessed by clicking the icon located next to the Brightness/Contrast/Backlight sliders in the Quick Settings, Settings and Advanced Settings menus.

The calibration menu is still work in progress and will soon be extended with further customization, 5K XR black-level adjustment, ability to upload custom chart images and support to save backlight+black-level parameters into per-game profiles.

Furthermode, IPD Offset & Screen Vertical adjustment sliders can now be linked to adjust both sliders simultanously. Changing to individual per-eye adjustment is still possible with one-click. Additionally, all selections from drop-down menus are now dynamically made upon selecting new value, without the need of using the previous “Load” buttons, to improve the user experience and efficiency. Therefore, all load-buttons for drop-downs have been removed.

Check the full change-log below for full list of new features and updates:

Ok, Im sorry for this but it seems like PiTool 266 still doesnt trigger backBrightness with 8KX.
We are uploading a specific PiTool version *87 which will fix that, and we will update the posts in a sec. Sorry for the trouble caused.


I can download the files with my phone ( firefox ) but on PC i get error file nog found ( firefox ) .

I have updated the first post with PiTool download link for version PiToolSetup_1.0.2.087_V2.0, which unfortunately is required for backlight brightness to work with all headsets.

PiTool version 266 will work with this PE, but to be able to change backlight brightness sliders, you will need PiToolSetup_1.0.2.087_V2.0.


Same situation for me : download from phone is OK but not possible from PC :thinking:

Could you please try another browser? Maybe Firefox is bloxking .exe files? It works good here with Chrome on all my PCs.

Just downloaded everything without problems from my PC (Firefox 83.0)


My Chrome is blocking here :thinking:

Great, thanks!
Please make sure to use the new PiTool 87 V2. We were 100% sure 266 did trigger the backlight but it turned out 87 V2 was an updated version and thats the latest that fixed the backlight trigger.

So what the real difference between 2.87 V2 vs .266 for 5k+ :thinking:


Backlight adjustment support for all Pimax headsets. PiTool version 266 didnt send/retrieve that argument to/from PE.

Thats basically it, other than that, the versions works the same :slight_smile:


This new PE update looks amazing!! Can’t wait to give it a go this evening. Great work guys.


while installing new Pitool from the link above I got error message that it did not install and I need v 266+, but it appeared to be installed anyway. I was doing clean install (removed all Pimax software prior to)

Is there any way to adjust/fine-tune IPD using images and/or charts?
