## Safe Lifting with Collision Detection

The built-in lifting system provides up to 65 cm of height adjustment, making it easy to position the screen for different seating arrangements and viewing requirements. A collision sensor detects unexpected external force and automatically stops the lifting movement, helping protect the display during operation.
