Ensure Adaptive Sync is enabled in both the monitor's OSD and your graphics card's control panel.

Gaming Features

The Spectrum One includes features designed to enhance your gaming experience:

Pixel-Perfect Upscaling: Uses integer-ratio pixel duplication for low-resolution input signals, maintaining the crisp look of pixel art and retro games.
Crosshair Overlay: An on-screen crosshair can be enabled via the OSD to assist aim in certain games.
Frame Rate Counter: Displays your current frame rate on screen, allowing you to monitor system performance.
Blur Busters Presets: Pre-tuned settings for optimal motion clarity.

Split Screen Mode

The monitor can display video from two separate sources simultaneously in split screen mode. Consult the OSD menu for options to configure Picture-by-Picture (PbP) or Picture-in-Picture (PiP) modes and select input sources for each window.

Glossy Panel Characteristics

This monitor features a glossy screen surface. This finish enhances color vibrancy, contrast, and image sharpness. However, it may also be more prone to reflections in brightly lit environments. Position the monitor carefully to minimize glare from light sources.

Maintenance

Cleaning the Monitor

To clean the screen, gently wipe it with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a non-abrasive, monitor-safe cleaning solution. Avoid using harsh chemicals or abrasive materials that could damage the screen surface. Ensure the monitor is powered off and unplugged before cleaning.

Firmware Updates

Periodically check the official Dough website for available firmware updates. Firmware updates can improve performance, add features, or resolve known issues. Note: Firmware updates for this monitor typically require a Windows operating system for installation. Follow the instructions provided on the manufacturer's website carefully when performing updates.
