KEY FEATURES 4K UHD resolution for stunning image clarity Germ-Resistant Screen Smart Eye-Care solution Instant plug and play TUV-Certified Low Blue Light Technology Blue light emissions from displays may cause adverse health effects such as macular degeneration or disrupted melatonin secretion. BenQ s Low Blue Light technology minimizes blue light exposure and allows for healthier time spent in front of the display, helping you create the best and most comfortable viewing experience for you and your students. TUV-Certified Flicker-Free Technology Flickering, which is the main cause for eye strain and visual fatigue, is the result of rapid change of bright backlight, a common phenomenon in most displays using Pulse Width Modulation (PWM) that turns the backlight on and off quickly in order to control the display s level of backlight brightness. BenQ s Flicker-Free technology is meticulously designed to remove LED backlight flickering while providing a zero-flicker viewing experience. This effectively reduces CVS-related eye problems and alleviates discomfort caused by looking at the screen all day. Anti-Glare Display Screen glare can cause reflected images on the screen, making it challenging for students to see, take notes, and remain focused. The RP553K s anti-glare glass surface can effectively reduce reflections, freeing students from excessive squinting with more legible text and clearer images, avoiding eye strain and facilitating more effective instruction. Intelligent Handwriting RecognitionThe RP553K s handwriting recognition feature allows presenters to simultaneously convert written text, numbers, forms, and drawings into legible materials without having to switch modes while effectively facilitating smooth teaching flow.
