FAQ

VR Features
VR player opens in Chrome. Clear Chrome cache on your phone using either path:
  1. Chrome → Settings → Privacy and security → Clear browsing data
  2. Chrome → History → Clear browsing data
In the app tap the VR button again. Chrome should reload the VR page from the beginning.
  1. Set up your VR headset lenses first.
    • Adjust lens distance (IPD) so each eye looks through the center of its lens.
    • Adjust focal length (focus/diopter or your headset’s focus wheel) until text edges are sharp.

  2. If the picture looks split in half:
    Most likely, you’re watching a regular (non-3D) video in SBS (Side-by-Side) 3D mode. In this mode, the left eye sees only the left half of the video, and the right eye sees the right half — which only works correctly with true SBS 3D videos.
    To fix this, press the 3D icon button to switch back to normal mode, where both eyes see the full video properly.
  1. We recommend Android 12 or later to support immersive Web–VR
  2. Size compatibility: 5.5″ – 7.0″ screen diagonal
  3. Resolution recommendations:
    FHD+ (1K, 1080×2400) – noticeable pixelation
    QHD (2K, 2560×1440) – crisp clarity
    QHD+ (3K, 3200×1440) or UHD (4K, 3840×2160) – crystal‑clear visuals
3D Features

3D Mode tells the player how the video is split for your eyes.

3D video formats: OFF, SBS, Top-Bottom
  • OFF — normal video (one image).
  • SBS — two images side by side (left / right).
  • TB — two images top and bottom.

How to choose:

  • Video split left/right → set 3D Mode = SBS
  • Video split top/bottom → set 3D Mode = TB
  • Normal video → set 3D Mode = OFF
  1. In your phone setup refresh rate 120Hz or 144Hz (Settings -> Display -> Refresh rate).
  2. Setup maximum display brightness.
  3. Start any 3D SBS video from the Playlist.
  4. Plug 3D Dongle into USB-port. The LED should be up.
  5. The video automatically switches from SBS to blurred 3D mode, and the Dongle LED starts to glow.
  6. On 3D Glasses press once a button (located on the upper side). Button starts to blink once in 3 seconds.
  7. When glasses catch the light from the 3D Dongle, they get synched, the frames darken.
  8. Put on 3D Glasses. In a video player controls press left/right buttons to adjust Base Advance parameter until the image is crisp.
  9. If the image is crisp but you feel the 3D image is uncomfortable, short press once the button on 3D Glasses to change left/right frames order.
If the image is crisp, but you see the 3D image is uncomfortable, short press once the button on 3D Glasses (located on the upper side) to change the left/right frames order.
  1. Make sure phone display rate is 120Hz.
  2. Make phone display brightness to the maximum.
  3. Make sure 3D Dongle LED glows when video is started.
  4. Switch off other sources of light. Fluorescent or LED lamps can affect glasses operation.
  5. Some phones (especially OnePlus phones) automatically drop the FPS from 120Hz to lower value. Make sure your phone keeps stable FPS 120Hz: for that start any video, press FPS button on upper right corner to see constantly FPS value.
    If your phone drops the FPS, follow the recommendations from FAQ: "What to do if my phone automatically drops the FPS"
  6. Some phones need USB extender to center the 3D Dongle in the middle of the display to make light signal straight and maximum.
After the glasses successfully connect with 3D Dongle, glasses frames become darkened.
Before sending the product to the customer, we double check the 3D Dongle operation on two different phones. The normal operation of 3D Dongle when plugged into USB port:
  1. When plugged, 3D Dongle LED gives short white flash.
  2. Inside the 3D VR Player, permission popup dialog appears: "Allow 3D VR Player to access 3D Dongle?"
  3. In the 3D VR Player, inside the submenu "FW Update" should be status: "3D Dongle firmware version X.XX. No need to update"

If 3D Dongle is not recognized by 3D VR Player, then:
  1. Over time the phone USB connector collects dust and grime. Please, look carefully and clean the connector by yourself (watch Youtube video) or send it for cleaning to technical service.
  2. Connect your phone to PC via USB cable. Your phone should be recognized by the PC.
  3. Plug 3D Dongle into the PC and check if the Dongle is recognized by the PC (on Windows open Device Manager, on Linux execute command dmesg or lsusb)
  1. Install the app SetEdit from Google Play
  2. Find the parameter "peak_refresh_rate" -> choose edit value -> set the value "59.99"
  3. If it does not take effect immediately, you may need to reboot the device.
