- OPTICAL This technology uses cameras. A touch event is registered with great accuracy when light is blocked by a finger or stylus. It’s the only touch technology that does not rely on an overlay or substrate to register a touch, so it's impossible to physically "wear out" the touchscreen. In fact you don’t really have to physically touch the screen. OVERDRIVE ON / OFF When very fast graphics are displayed your monitor can sometimes get blurry. Turning on the Over Drive feature will eliminate that. SPEAKERS This LED monitor is equipped with two high quality stereo speakers. ACR Contrast Ratio is a measurement of the difference between the darkest black & the brightest white your monitor can display. Advanced Contrast Ratio is a feature that automatically adjusts contrast & brightness of the screen to assure perfect picture quality while watching films & playing games. VESA VESA mount compliance means you can easily mount the LFD to any mounting that complies with the VESA standard.
