Picture and Sound Quality

The QN900B offers impressive visual and audio capabilities. Proper configuration maximizes its potential for an immersive viewing experience.

Adjusting Picture Settings for Optimal Brightness and Contrast

To get the best picture from your QN900B, start by calibrating brightness and contrast. Access the picture settings menu and use a calibration disc or built-in test patterns. Adjust the backlight to suit your room’s lighting. Set contrast to enhance detail without washing out bright areas.

Quantum Matrix Technology Pro enables precise light control. Fine-tune local dimming for deep blacks and bright highlights. Enable HDR for compatible content to expand the dynamic range.

Quantum Dot technology provides vibrant colors. Use the Color Space settings to match your content. For movies, try the “Filmmaker Mode” preset for an accurate cinematic look.

Enhancing Audio with Q-Symphony and Dolby Atmos

Dolby Atmos creates a 3D soundstage. Enable it in the audio settings menu for supported content. For best results, use upward-firing speakers or a Dolby Atmos soundbar.

Consider room acoustics. Soft furnishings help reduce echoes. Experiment with speaker placement for optimal sound distribution.

Synchronizing Audio-Video with Game Mode and Motion Xcelerator Turbo Pro

Gamers can minimize input lag and enhance motion clarity. Enable Game Mode in the General settings menu. This reduces video processing for faster response times.

Motion Xcelerator Turbo Pro boosts the refresh rate to 120Hz for supported games. To activate:
