AUO G270QAN01.4 27 Inch QHD LCD Display – 2000:1 High Contrast AHVA Industrial Panel
Product Overview
The AUO G270QAN01.4 is a 27.0-inch industrial-grade TFT-LCD display module manufactured by AU Optronics (AUO). This panel delivers stunning Quad-HD resolution (2560×1440) in a 16:9 widescreen format, specifically engineered for industrial HMI, medical imaging equipment, professional design workstations, and video editing applications requiring exceptional image clarity and high contrast.
Key differentiator: With an outstanding 2000:1 contrast ratio—twice as high as standard IPS panels (typically 1000:1)—the G270QAN01.4 delivers deeper blacks, brighter whites, and significantly more vivid images. Combined with QHD resolution (2560×1440, 108 PPI)—approximately 78% more pixels than FHD—this panel offers exceptional detail and image depth for professional applications.
Equipped with AHVA (AUO Advanced Hyper-Viewing Angle) technology—similar to IPS—this display offers full 89/89/89/89° viewing angles with no grayscale inversion effect. The Normally Black mode provides deeper blacks and better contrast in dark environments. With 400 cd/m² brightness, 50,000-hour WLED backlight life, and an anti-glare matte surface, the G270QAN01.4 delivers exceptional visual performance for the most demanding professional environments.

Key Advantages
1. QHD Resolution (2560×1440) – 78% More Pixels than FHD
The G270QAN01.4 delivers stunning Quad-HD resolution with 108 PPI pixel density—approximately 78% more pixels than standard FHD (1920×1080) displays. Key benefits include:
Exceptional image detail — perfect for medical imaging, CAD/CAM, and graphic design
More screen real estate — multitask with multiple windows side by side
Sharper text rendering — reduced eye strain during long work sessions
Crisp, detailed imagery — ideal for data visualization and monitoring
2. 2000:1 Ultra-High Contrast Ratio
The G270QAN01.4 delivers a remarkable 2000:1 contrast ratio—twice as high as standard IPS panels (typically 1000:1). Key benefits include:
Exceptional black levels — perfect for medical imaging and dark environment viewing
Superior image depth — enhanced visual experience for diagnostic applications
Excellent grayscale reproduction — critical for PACS and medical displays
Vibrant, lifelike colors — 80% NTSC color gamut for accurate color reproduction
3. AHVA Wide Viewing Angle Technology
The G270QAN01.4 incorporates AUO's proprietary AHVA technology (Advanced Hyper-Viewing Angle), delivering full 89-degree viewing angles in all directions. Key benefits include:
Excellent off-axis readability — no color shift or contrast loss from any angle
Superior color consistency — accurate colors across the entire viewing cone
No grayscale inversion — unlike conventional TN panels
Normally Black mode — deeper blacks and better contrast in dark environments
4. High Brightness & Long Life Backlight (400 cd/m², 50,000 hrs)
The panel features a 400 cd/m² typical brightness and 50,000-hour WLED backlight life:
