Try one of the following options if you are noticing focus issues with Cosmos Laser:

1. Update the firmware of the 4K dongle and Cosmos Laser to the latest version:

- Press the Settings button on the remote and select Settings > Device Preferences > About > System Update.

- Press the Settings button on the remote and select Settings > Device Preferences > About > Projector Firmware Update.

3. Press the Settings button on the projector or the Source button on the remote, and select Advanced Settings > ToF - Calibration to calibrate the autofocus.

4. Place the projector between 5-13 ft (1.5-4 m) away from your screen.
