Hi folks. I don't think my Crystal Light is adjusted properly. I believe I need offset adjustments. But I have read AI instructions for doing it and watched some videos which were old outdated. They talked about using SteamVR bvlack home screen and then adjusting the offsets in Pimax Play using the arrow keys while wearing the headset. I cannot find any way using the new Pimax Play to adjust the offsets using the arrow keys.

Can someone who has adjusted their IPD offsets please explain to me how you did it? I am not liking the clarity of my headset at all right now and I believe it is because it is not adjusted properly. 

Please help. I have the crystal light and the newest Pimax Play V2.

Can it be true that no one in our large forum uses IPD offsets with their Pimax headset? 

Sorry, I don't have a Pimax headset, but isn't there some internal menus in the headset with settings that let you adjust things like IPD ?

Probably better to ask on official pimax channels, more chance of a quicker response there.

here:

or what I usually do: AI

On the Pimax Crystal Light, there are two different things people mix up:

• Physical IPD → moves the lenses

• IPD offset (software) → shifts the image per eye for fine alignment

You’re asking about the offset, which is the software tweak—here’s how to actually adjust it.

🧭 Where to adjust IPD offset

You do it inside Pimax Play (or older PiTool):

1. Open Pimax Play

2. Go to Device Settings → IPD / Advanced

3. Find:

   • Horizontal IPD Offset

   • Vertical IPD Offset

4. Adjust sliders (usually per eye: left/right)

That’s the only place—there’s no physical “offset” control on the headset.

---

⚙️ What the offsets actually do

• Horizontal offset → shifts image left/right per eye

• Vertical offset → shifts image up/down per eye

They don’t move lenses—just the rendered image. This helps if your eyes aren’t perfectly symmetrical or the headset fit isn’t perfect. (Pimax Store)

---

🎯 How to tune it properly (practical method)

Step-by-step:

1. Set your physical IPD first

   • Use the headset dial/wheel until image is sharp

   • (Crystal Light uses a manual dial on the headset) (Pimax Support)

2. Look at a distant object in VR

   • Horizon, stars, UI crosshair—anything far away works best

3. Adjust horizontal offset

   • Move slider slowly

   • Goal: both eyes “merge” perfectly (no double image)

   • Stop when:

     • image feels centered

     • no eye strain

4. Adjust vertical offset (if needed)

   • Fix blur where top/bottom looks off

   • Even tiny changes matter (±0.5 mm can be noticeable)

5. Re-check comfort

   • You should feel:

     • no eye strain

     • stable depth

     • clear center image

⚠️ Important tips (most people miss these)

• Fit matters as much as settings
  If the headset sits wrong, offsets won’t fix it (Pimax Store)

• Use small adjustments
  Offsets are fine tuning, not big corrections

• Don’t skip physical IPD first
  Offset cannot fix badly set lens distance

• Check during real use (games/sims)
  Menus can look fine while gameplay still feels off

---

🧠 Quick rule of thumb

• Double vision → adjust horizontal offset

• Blur top/bottom → adjust vertical offset

• General blur → fix physical IPD or headset position first

---

If you want, tell me what you’re seeing (e.g., “one eye blurry,” “cross-eyed feeling,” “far objects double”), and I can give you exact offset directions (+/- values) to try.

Thank you for this. I’m not home until tonight but I’ll play around a bit and give some feedback tomorrow. Really appreciate this info.

When I look dead center it doesn't look completel;y clear. If I turn my head slightly to the left, I can reach a point where the right eye looks clear. If I turn my head slightly to the right, I don't find that same spot where the left eye is clear. I probably should add that I am using custom prescription lenses with the headset.

me too, they have to be very specific for the Pimax, not the same value as your normal reading glasses.

"Far distance prescription (from your everyday glasses – we'll adjust your prescription for the headset's focus distance)"

I think the OP knows this already but that wheel on the Pimax Crystal Light will display digits onto whatever you see in VR. The numbers are the IPD offset. 

After the offset is then also adjusted digitally in pimax play, if required, then you can increase or decrease the 3D depth without changing IPD offset physically or digitally using PrimaShock app for OpenXRToolKit. He has a version 2 which uses 2 other replacement files which I do not like at all. It is supposed to increase performance, but in my opinion it makes the view look game like, not real. So I only use version one:

IPD adjustment is not the same as IPD offset adjustment.
