Frequently Asked Questions - EH2B Klarstein

How do I connect my laptop to the EH2B projector?

Use an HDMI cable to connect your laptop's HDMI output to one of the projector's HDMI inputs. Then select the corresponding HDMI source via the remote or projector menu.

Can I wirelessly mirror my smartphone screen?

Yes, the EH2B supports screen mirroring via Wi-Fi. For iOS, use AirPlay; for Android, use Miracast or the built-in screen mirroring feature. Ensure both devices are on the same network.

How to adjust the image size and focus?

Turn the zoom ring on the lens to adjust image size, and the focus ring to sharpen the image. You can also move the projector closer or farther from the screen.

What is the recommended projection distance for a 100-inch screen?

With a throw ratio of 1.2:1, you need about 2.5 to 3.0 meters (8-10 feet) to project a 100-inch diagonal image.

How often should I replace the lamp?

The lamp is rated for up to 50,000 hours under normal use. Replace it when the image becomes dim or the lamp indicator flashes.

Can I use the projector for outdoor movies?

Yes, but it requires a dark environment and a suitable screen. Ensure the projector is protected from moisture and dust, and use an outdoor-rated extension cord.

Does the projector support 4K input?

The EH2B has a native Full HD resolution (1920x1080). It can accept 4K signals but will downscale them to 1080p for display.

What to do if the projector overheats?

Ensure the ventilation grilles are not blocked. Clean any dust from the vents. If overheating persists, reduce ambient temperature or lower the brightness setting.

How to clean the projector lens?

Use a soft, lint-free microfiber cloth slightly dampened with lens cleaner (or water). Gently wipe the lens in a circular motion. Never use abrasive materials.

Is the projector compatible with a ceiling mount?

Yes, the EH2B has a standard tripod screw hole (1/4 inch) and can be mounted using a universal projector ceiling mount with the appropriate screws.
