[FAQ] Getting Started 5k & 8k

Okay folks I have Invited you all here to work on a getting Started guide for the new pimax headsets this topic is hidden while we work.


This is along the lines @D3Pixel suggested. Next post will be a a wiki & any here can Edit it.

Pimax 5K+ / 8K Installation Troubleshooting Guide

The guide should include a “Before you connect the device” paragraph. Then a list of troubleshooting steps that people come across.


Preparing To Install:

1) Computer
  • Uninstall any old PiTool software using CCleaner
  • Reboot
  • Download latest PiTool from http://xyz.com
    Scan it
2) Hmd
  1. Check Headset Plug on headset side. Press firmly in as may have come loose during Shipping.
  2. Insert Display Port cable in. Plug in USB into USB 3.X (Red USB are usually 3.1)
  3. Plug in Wall Adapter & insert power to HMD.
  4. Lighthouse v1.0 Setup Tips if owned. @DrWilken

NViDiA GTX 9Series & 10Series

  • Download Nvidia BiOS Firmware update tool to enable DP 1.4 Features (Also helps headset Connection Issues)

Pitool Menu Options

Status Menu
  1. Launch SteamVR
  2. Launch Room Setup
    *NOTE: Even without Lighthouses first time setup requires Room Setup to be ran. Goto Settings\HMD and turn Off Lighthouse tracking; if you do not have Lighthouses (3DOF).

Settings General
  1. Checks for New Version Of Pitool to Download.
  2. Select Language.
  3. Choose Whether Pitool Runs On Bootup.
  4. Option to Exit Pitool or Hide in Taskbar Tray.
  5. Start PiHome 3d Unity Enviroment. (Recommend Off - Saves Resources)
  6. Restore Defaults

Settings HMD

  2. Toggles Lighthouse Tracking On/Off
  3. Toggles Hidden Area Mask On/Off (Leave On See Note)
  4. Brightness Level Options Low/Normal/High
  5. Render Multiplier Default 1 (Change Requires Restart SteamVR)
  6. Calibrate Horizon ?Info coming soon
  7. Reboots HMD
  8. Restore Default HMD Settings

NOTE Hidden Mask Explained By @StonebrickStudios

The hidden area mask describes the black pixels here:

It’s very significant optimization. When it’s disabled, you pay full rendering cost for all pixels, even the ones that are outside of the area that’s visible through the lense. The hidden area mask is always enabled on all other HMDs (Vive, Rift, WMR etc), they don’t allow you to disable it. It’s something that should never really be changed, and almost no game should have issues with the hidden area mask, and if there’s a game that has, that would fully be the responsibility of the devs to fix. Everyone should really always keep it enabled, unless you see issues related to it, which would be black areas in your FOV that should not be black.

Settings Brainwarp WiP - Pics coming soon

Parallel Projections

Change Requires Restart SteamVR!

  • This is a compatibility setting for games that do not support rendering “cantered” (angled) displays. If you experience “double vision” like effect; turn on. This setting does cause a performance hit when required.
Field Of View

Change Requires Restart SteamVR

  • Small (Approx 120°) Best Compatability
  • Normal (Approx 150°)* Reccommended
  • Large (Approx 170°)

Q: What is the difference between LH v1.0 & LH v2.0? Are the compatible?
A1: Lighthouse v1.0 is not compatible to use with Lighthouse v1.0.
A2: Lighthouse v1.0 is compatible with Tracking v1.0 & Tracking v2.0.
A3: Lighthouse v2.0 is only compatible with Tracking v2.0 headsets & accesories.

Detailed Info on Lighthouse Versions

Info provided by @Nim

From what I understand, there is no technical difference between lighthouses between Pimax and HTC. The only differences between any Valve Lighthouses is the 1.0 and 2.0 spec. They are all made by valve with a skin on them. Therefore if your device works with whatever lighthouse version you are running, it should work regardless of who you bought the lighthouse from.

So basically, follow this diagram. If your device is a 1.0 tracker, it will only work with 1.0 lighthouses. If it is a 2.0 tracker, it will work with all lighthouses.

The original vive lighthouses were 1.0, the ones shipping with the vive pro are now 2.0. The pro then logically has to have 2.0 tracking for it to work with the lighthouses it ships with (since a 1.0 couldnt work with 2.0 lighhouses). Pimax is shipping the 8k with 2.0 lighthouses, and using the same logic has 2.0 tracking built in. Controllers should be the same deal for both.

Q:Headset not discovered when plugged in
A: Disable Bios GPU, Restart

Q: Installed PiTool over old version, now HMD not work.
A: Install version .76 from here :
http://piplayus.pimaxvr.com/PiToolSetup_1.0.1.76.exe and let it auto update itself. Reboot

Q: Light flashes red on front of HMD
A: Light flashed red means DP and USB get connection problem. Please check the USB and DP cable.
If connected, the light will turn green.
If it is still disconnected, contact Pimax support support@pimaxvr.com

Q: HMD &or Controllers not Tracking?
A1: Please make sure you have turned on Lighthouse tracking item On Pitool(Setting General No 2) and keep the base station power on.
A2: Use the Following Tool to test USB Port Latencies LatencyMon Choose one with Lowest Value; Also Best with USB 3.x (3.1 or higher best, Usually Red Ports).
A3: Other Solutions in Troubleshooting Wiki

Q: Pitool fails to launch Oculus Games; Missing Oculus Service?
A: AntiVirus may have blocked a Pitool file.

  1. Reinstall Pitool Offline with AV disabled.
  2. Enable AV Reboot go online.

Q: Changed FoV; no difference in SteamVR?
A: Changing FoV Option requires SteamVR restart to take effect.

Q; HMD works but view is all wrong
A: Some games require old projection setting in PiTool (requires SteamVR Restart)
you could check the game list as below:

Q: Headset Microphone volume too low
A: Install and run the programs as explained in the below link:

Q: 8k Headset has Horizontal lines (like scanlines) when moving head?
A: Contact Support. Support can fix with software via a remote Session.

Known incompatibilities

  1. NVidia Driver XYZ is known to cause tracking issues

Think I have invited a good chunk of users whom have the headset & team members. Please add your name to the wiki post as all will be contributors

Hi there, I’ve taken screen captures of many solutions to frequent problems early backers have found, I’ll upload them when I have a minute since they could be useful.


When having a difficult hardware problem post your system specs by

  1. Open Steam
  2. Click Help menu at the top
  3. Click System Info
  4. Copy and Paste that along with your problem

A more in-depth report (and system check) can be created through the Microsoft tool DXDIAG.

  1. Click START button so menu slides up
  2. Just start typing “DXDIAG” and click the icon that appears to launch it
  3. Wait for the little green diagnose bar to complete
  4. Click each tab and you want “No Problems Found” under the Notes of each tab.
  5. Click the button “Save All Information” and save the file to your desktop (usually DxDiag.txt)
  6. Open that file and scroll to the bottom where crash reports are listed. You may find something there that helps identify an issue.

The DxDiag.txt file is often sent to support engineers so they can compare your driver versions with known issues.

Advanced troubleshooting

  1. Right click the Start Button
  2. Left Click “Event Viewer”
  3. In the main window you can view the summary of Critical errors and normal errors that have been logged by windows. This is very helpful in finding issues with your system. You can double click an error to view more info on it. You can also clear the logs, reboot and then re-run these steps to see anything that failed since clearing the logs.

For USB diagnostics I like to use the excellent tools by NirSoft, in this case try USBDeview You can filter to only display connected devices (Options->Display Disconnected Devices) and also see when devices register and de-register themselves along with their power draw. It can help you identify what those annoying connect/disconnect windows chimes are for example.


Check that connected devices have not failed

  1. Right click start button
  2. Left click Device Manager

Nothing listed should have a yellow exclamation mark next to it.


I will be able to reply properly when I’m back from Microsoft conference end of the week.

I have a compilation of various topics (including hardware and software solutions). It is a wiki if any of you want to contribute.

Feel free to cherry-pick some of the solutions for this FAQ.


A post was split to a new topic: Rec 5k+ Tried Getting Started Faq

Did this “Getting Started” guide ever happen? I’ve been searching and it all just seems to lead back to this thread. There are troubleshooting ones everywhere, but a nice clean step by step following Pimax’s piece of paper that says “plug it in here” might be helpful.

I think I have done most everything right, but after 4 days of struggling with it, I have yet to play a game other than the War Robots VR demo which worked beautifully. No luck with anything else.

Today I came searching for a basic guide to start all over which lead me to this thread.

This is the thread. Anyone can add to the wiki. I haven’t gotteb back to updating with pics of the other sections. For FFR for example I need someone with an RTX card to provide a pic of features my 1080ti doesn’t show. :nerd_face:

Will maybe see about pics of where to plug in. But usb, dp & wall plug is all we have. Usb seems to have varying results & I’m sure most folks won’t use the mobo dp. :beers::smirk::+1::sparkles:

lol, the plugging in part is easy.

When I decided to start over from scratch instead of winging it like I did when I received the headset, I searched and found your opening post with the pitool, status, and settings all numbered and thought “Ahh, this is just what I am looking for”. I guess it’s that particular part that didn’t seem to go any further that I think might be helpful.

I fully understand everything takes too much time! Just wanted to make sure I wasn’t missing something obvious. :slight_smile:

Unfortunately no. Just no where near complete. Will try to get back at it sometime. Are you running an RTX card by chance?

no, 1080ti here I also have no lighthouses and controllers, so trying to get by with an xbox controller, and I think that is only adding to my issues. One quick question though. I thought I would start with an early stable version of pitool and then work my way up through them just from a learning and “seeing the changes” perspective, but now I am wondering if that is a mistake. I am on 95. Would you suggest going straight to 112 or even the 121 beta?
