Cocar 3D Active Shutter Glasses 144Hz Rechargeable (Pack of

Cocar 3D Active Shutter Rechargeable Glasses (pack of 2) are battery-rechargeable active-shutter eyewear designed to sync with DLP Link projectors for high-refresh 3D viewing at 144Hz.

These active shutter glasses from Cocar use DLP Link synchronization and a 144Hz refresh rate to deliver sharp, low-ghosting 3D images for home theaters, classrooms, and presentation rooms. They come as a two-piece set, include built-in rechargeable batteries with long runtime, simple one-button operation, and a 2D-to-3D flip feature that helps correct left/right view orientation when pairing with projectors.

How do these glasses connect to my DLP Link projector?

Connection is automatic through DLP Link—no separate RF or IR emitter is required. Once the projector emits the DLP Link sync signal, the glasses detect and lock to it, providing frame-accurate shuttering for each eye.

• Uses DLP Link sync method; compatible with projectors that support DLP Link.
• No external base station or emitter needed; sync is embedded in the projector image.
• Not compatible with televisions that lack DLP Link support.
• Includes pairing tips in the manual to troubleshoot initial connection.

What visual performance can I expect with 144Hz active shutters?

The 144Hz refresh rate means each eye receives a higher frame frequency than older 120Hz or 96Hz models, which reduces motion blur and visible flicker for smoother 3D motion. The active shutter design also minimizes ghosting so depth appears cleaner and more stable.

• Super-fast 144Hz refresh rate for reduced motion blur.
• Active shutters alternate lenses in sync with the projector frames.
• Engineered to reduce ghosting and flicker compared to lower refresh rates.
• Delivers clearer perceived depth in fast-moving scenes.

How long do they run and how do I charge them?

Cocar glasses include built-in high-capacity rechargeable batteries that provide extended use between charges and convenient USB charging. They offer long continuous runtime and go into standby or auto-off modes to conserve energy when not in active use.

• Up to 45 hours continuous playback after a full USB charge.
• Auto 5-second standby and automatic 5-minute shutoff to save power.
• USB recharging—no disposable batteries required.
• Standby retention of up to 180 days when not in active use.

What if my 3D image looks reversed or doesn’t appear?

These glasses include a 2D-to-3D flip function and a simple method to swap left/right eye views if the stereo channels are reversed. Use your projector’s remote controls and the switch on the glasses to correct orientation and optimize the 3D effect.

• 2D-to-3D flip: press the glasses’ switch after toggling the projector remote’s volume up/down.
• Manual left/right flip corrects reversed stereo channels quickly.
• Detailed steps included in the user manual for troubleshooting pairing and view swapping.
• One-button operation keeps day-to-day use straightforward.

Who is this for? These Cocar active shutter glasses are aimed at anyone who owns a DLP Link–capable projector and wants reusable, rechargeable 3D eyewear for movie nights, educational presentations, corporate demos, or immersive gaming. They suit small groups or families (sold as a twin pack), renters who prefer non-permanent setups, and AV technicians who need dependable, high-refresh glasses with long battery life and simple controls. Note: they are not a universal solution for TVs or non-DLP Link systems—confirm your projector’s compatibility before purchasing.
