Function Description

The VIOTEK GNV27DB2 is a gaming monitor designed to display video output from a computer or other compatible devices. It features a range of input ports, including DisplayPort (DP) and HDMI, to connect to various video sources. The monitor is equipped with an On-Screen Display (OSD) menu that allows users to adjust various settings such as brightness, contrast, color, and display modes to optimize the viewing experience. A key feature for gamers is the VIOTEK Adaptive Sync, which eliminates image tearing, stuttering, and ghosting by synchronizing the monitor's refresh rate with the graphics card's frame rate. This feature is compatible with GPUs using AMD® FreeSync™ or NVIDIA® G-Sync™ and requires a DisplayPort connection. The monitor also includes ECO modes and Gameplus features, providing optimized settings for different activities and in-game enhancements like crosshairs. An audio output port allows for connection to external speakers or headphones.

Usage Features

The monitor offers a user-friendly interface for basic operation and advanced customization. To get started, users connect the monitor to a power source and a computer using either a DisplayPort or HDMI cable. The power button turns the monitor on or off, and an LED indicator provides visual feedback on its status (solid blue for normal operation, flashing blue for no signal or low voltage).

The OSD menu is the central hub for adjusting monitor settings. It can be accessed by pressing the 'M' (Menu) button after activating the navigation window. Within the OSD, users can navigate through various categories using the 'Up' and 'Down' buttons and select options with the 'M' button. The 'E' (Exit) button allows users to exit the current screen or the OSD menu.

Key OSD functions include:

Input Source: Allows selection of the video input from DP, HDMI1, HDMI2, or HDMI3.
Brightness/Contrast: Adjusts the display's brightness, black level, and contrast. It also includes a Dynamic Contrast Ratio (DCR) function for enhanced image quality.
Color Setting: Provides options to adjust color temperature (Warm, Cool, User), low blue light filtering, hue, and saturation.
Picture Quality Setting: Includes picture modes (Standard, Photo, Movie, Game, FPS, RTS) optimized for different content, response time adjustments (Off, High, Middle, Low), noise reduction, super resolution for enhancing low-resolution images, and dynamic luminous control for gray scale display.
MPRT (Moving Picture Response Time): A feature to reduce motion blur.
Display: Allows adjustment of aspect ratio (Wide Screen, 4:3, 1:1, Auto) and LED mode (Normal, Off, Flicker).
Audio: Controls mute function and volume, and allows selection of the audio input source (Auto Source, HDMI1, HDMI2, HDMI3, DP).
Multi-Window: Supports Picture-in-Picture (PIP) and Picture-by-Picture (PBP) modes, enabling display of multiple input signals simultaneously. Users can adjust PIP/PBP size, position, and swap signal sources.
OSD Settings: Customizes the OSD menu itself, including language, horizontal and vertical position, transparency, time-out duration, and rotation.
Other: Includes DP version selection, HDR mode control (Off, On, Auto Detect), and Adaptive-Sync activation (On, Off).
Reset: Resets all monitor configurations to default.

Beyond the OSD, dedicated buttons provide quick access to specific features:

Pressing the 'Down' button (▼) in the navigation window cycles through Gameplus modes, offering different crosshair icons for improved aiming in games.
Pressing the 'Up' button (▲) cycles through ECO modes (Standard, Photo, Movie, Game, FPS, RTS), which optimize display settings for various activities.
Pressing the 'E' button (E) switches the color gamut mode between "Limited" and "Full" when using compatible graphics cards and DP or HDMI cables.

Troubleshooting tips are provided for common issues such as a blank screen, out-of-focus image, flashing screen, "cannot plug and play" errors, dim image, image jitter/moire patterns, and color problems. These tips guide users to check power, cable connections, graphics card installation, and monitor settings.

Maintenance Features

The manual outlines clear instructions for cleaning the monitor to ensure its longevity and proper functioning.

Preparation: Before cleaning, the monitor and PC must be powered off, and the power cord disconnected from the product.
Safety Precaution: Users are explicitly warned not to touch any cords or cables with wet hands to prevent electric shock.
Dust and Debris Removal: A dry, non-abrasive cloth should be used to gently remove dust and debris from the monitor.
Exterior Cleaning: For the exterior, a soft cloth lightly dampened with water, and wrung out well, should be used for gentle wiping.
Prohibited Cleaners: It is crucial not to use alcohol, solvent, surfactant, or ammonia-based cleaning solutions. Additionally, users should not spray water or detergent directly on the product.
Screen Protection: Users are advised not to press the monitor display with hands or other objects to avoid damaging the screen.
Post-Cleaning: After cleaning, the power cord should be reconnected, and the product and PC powered on.

The manual also emphasizes general safety precautions, such as unplugging the monitor before cleaning, avoiding blocking ventilation openings, keeping the monitor away from heat sources, and not inserting anything into the monitor's openings. It also warns against disassembling or modifying the monitor, as this can lead to damage, injury, or death and will void the warranty.
