Product Description
The Lenovo D20-30 (66E9KAC4MY) is a compact, energy-efficient 19.5-inch HD+ desktop monitor engineered for daily office tasks, virtual learning, light computing, and home entertainment setups. Finished in a clean Raven Black chassis, it features an ultra-compact footprint that easily fits onto tight work desks or shared workstations.
Equipped with a 19.5-inch Twisted Nematic (TN) anti-glare display, the monitor outputs an HD+ resolution of $1600 \times 900$ in a 16:10 standard aspect ratio. Delivering a peak brightness of $250\text{ cd/m²}$, a static contrast ratio of $1000:1$, and a 72% NTSC color gamut, it presents sharp text details, spreadsheets, and media visuals clearly. Designed with speed in mind, its ultra-fast 2ms response time (Extreme mode) minimizes motion blur and ghosting during video playback or casual gaming.
Prioritizing user health during long work sessions, the Lenovo D20-30 features TÃœV Rheinland-certified Low Blue Light and Flicker-Free screen technologies, which reduce harmful blue spectrum emissions and screen flickering to minimize eye fatigue.
Connectivity options include an HDMI 1.4 port for modern PCs, laptops, and consoles, along with a classic VGA port for legacy desktop compatibility. For flexible setup configurations, the monitor stand supports tilt adjustment from $-5^\circ$ to $+22^\circ$ and includes standard $100 \times 100\text{ mm}$ VESA mounting holes for easy installation on wall brackets or desktop monitor arms.
