Digital Cinema Concepts HD979: Computer monitors 1080p content
Most widescreen cathode ray tube (CRT) and liquid crystal display (LCD) monitors can natively display 1080p content. For example, widescreen WUXGA monitors support 1920x1200 resolution, which can display a pixel for pixel reproduction of the 1080p (1920x1080) format. Additionally, many 23, 24, and 27-inch (690 mm) widescreen LCD monitors use 1920x1200 as their native resolution; 30 inch displays can display beyond 1080p at up to 2560x1600 (1600p). Many 27" monitors have native resolutions of 2560x1440 and hence operate at 1440p.
Interlaced video technique
Interlaced video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured at two different times. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon effect.
This effectively doubles the time resolution (also called temporal resolution) as compared to non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. Only CRT displays and ALiS plasma displays are capable of displaying interlaced signals, due to the electronic scanning and lack of apparent fixed-resolution.Digital Cinema Concepts review
Digital Cinema Concepts sell: Interlacing problems
When someone watches interlaced video on a progressive monitor with poor deinterlacing, they can see "combing" in movement between two fields of one frame.
Interlaced video is designed to be captured, stored, transmitted, and displayed in the same interlaced format. Because each interlaced video frame is two fields captured at different moments in time, interlaced video frames can exhibit motion artifacts known as interlacing effects, or combing, if recorded objects move fast enough to be in different positions when each individual field is captured. These artifacts may be more visible when interlaced video is displayed at a slower speed than it was captured, or in still frames.
Contrast ratio capability
It is common to market only the dynamic contrast ratio capability of a display (when it is better than its static contrast ratio only on paper), which should not be directly compared to the static contrast ratio. A plasma display with a 4,000,000:1 static contrast ratio will show superior contrast to an LCD (with LED or CCFL backlight) with 30,000,000:1 dynamic and 20,000:1 static contrast ratio when the input signal contains a full range of brightnesses from 0 to 100% simultaneously. They will, however, be on par when input signal ranges only from 0 to 20% brightness. Digital Cinema Concepts
Digital Cinema Concepts HD979:Contrast ratio
The contrast ratio is a property of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display. It has similarities with dynamic range.
