This guide is for anyone watching SBS (side-by-side) 3D video on a Meta Quest 3 who's running into a flat, doubled, or oddly stretched image. Almost every SBS playback problem on Quest 3 comes down to one of three settings: format detection, eye order, and aspect ratio. None of these are hardware faults — they're player configuration, and each has a specific fix below.
Format & Layout Settings
- Format: confirm the player is set to "Side-by-Side" and not "Over/Under" or "Mono" — mismatches cause a flat or doubled image.
- Eye order: if depth looks inverted (background appears in front), toggle left/right eye order in the player settings.
- Aspect ratio: full-width SBS video is often 2:1 combined — make sure the player isn't stretching each half to a 16:9 frame, which flattens the effect.
Quick Troubleshooting Reference
| Symptom | Likely cause | Fix |
|---|---|---|
| Image looks flat or doubled | Wrong format mode selected | Set player to Side-by-Side, not Over/Under or Mono |
| Depth looks inverted | Eye order swapped | Toggle left/right eye order in player settings |
| Image looks stretched or squashed | Wrong aspect ratio | Confirm player isn't stretching each half to 16:9 |
| Eye strain during long sessions | IPD mismatch or brightness | Run eye-tracking calibration; lower brightness |
Comfort Settings
Reduce IPD mismatch by running the Quest 3 eye-tracking calibration in Settings → Device before long viewing sessions, and keep brightness moderate to avoid eye strain during extended 3D playback.

Frequently Asked Questions
Why does SBS video look flat or doubled on Quest 3?
This is almost always a format mismatch. Confirm the player is set to Side-by-Side and not Over/Under or Mono, since a mismatch causes a flat or doubled image regardless of the source file itself.
Why does the depth look inverted on Meta Quest 3?
If the background appears to be in front of the foreground, the eye order is likely swapped. Toggle left/right eye order in the player settings to correct it.
Why does SBS video look stretched or squashed on Quest 3?
Full-width SBS video is often 2:1 combined, so if the player stretches each half to a 16:9 frame instead of respecting the true aspect ratio, it flattens the 3D effect. Check the player's aspect ratio setting.
How do I reduce eye strain when watching 3D video on Quest 3?
Run the Quest 3 eye-tracking calibration in Settings, then Device, before long viewing sessions to reduce IPD mismatch, and keep brightness moderate during extended 3D playback.
