Full HD Monitors
with LED
Stunning front-of-screen experience
Built to provide you with enhanced digital content consumption and creation, the ST2420L and ST2421L
monitors up the ante by delivering cinematic quality pictures that make watching movies, playing games,
and photo editing an amazing experience with a 1920 x 1080 full HD resolution, mega contrast ratio,
response time of 5ms (typical, black to white) and a 16:9 aspect ratio.
Environmentally-conscious display technology
Designed to meet high environmental standards, the ST2420L & ST2421L monitors use materials such
as arsenic-free glass and mercury-free panels. The LCD panels with LED backlights also meet the latest
ENERGY STAR 5.0 compliance standards, which help you reduce your energy consumption without
compromising on performance.
Elegant slim design
Stylishly designed with its bottom front bezel beautifully lit when switched on, intuitive touch controls on
the bottom right panel and a slim panel depth, it is no wonder the glossy black ST monitor is a head turner.
Superb connectivity
You can seamlessly connect your monitor with your desktop, laptop, gaming console and other peripherals
with the VGA and DVI-D (HDCP) ports. The HDMI port also gives you uncompromised high quality video and
audio performance.
