Digital Fine Contrast is a contrast-enhancing display technology introduced in 2006 by LG Display.It is used in the company's "Flatron" line of TFT monitors and implements a 'smart function' whereby it dynamically detects the characteristics of each frame to be displayed and automatically adjusts its contrast to obtain a sharper and more vivid image.
Additional products include Apple's 20-inch Cinema Display and Dell's UltraSharp 2005FPW LCD Monitor. These use the "LG.Philips" branding. [14] As of 2022, LG Display is the manufacturer of the OLED panels used in Sony's OLED TVs. [15] As of late 2022, LG Display was one of the two suppliers for displays for the iPhone 14 Pro, along with ...
System sharpness is affected by the lens (design and manufacturing quality, focal length, aperture, and distance from the image center) and sensor (pixel count and anti-aliasing filter). In the field, sharpness is affected by camera shake (a good tripod can be helpful), focus accuracy, and atmospheric disturbances (thermal effects and aerosols).
Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness).. The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
Overscan is a behaviour in certain television sets in which part of the input picture is cut off by the visible bounds of the screen. It exists because cathode-ray tube (CRT) television sets from the 1930s to the early 2000s were highly variable in how the video image was positioned within the borders of the screen.

On larger CRT monitors (17 in or 43 cm or larger), most people experience mild discomfort unless the refresh is set to 72 Hz or higher. A rate of 100 Hz is comfortable at almost any size. However, this does not apply to LCD monitors. The closest equivalent to a refresh rate on an LCD monitor is its frame rate, which is often locked at 60 fps ...
If the difference is greater than a user-specified threshold setting, the images are (in effect) subtracted. Digital unsharp masking is a flexible and powerful way to increase sharpness, especially in scanned images. Unfortunately, it may create unwanted conspicuous edge effects or increase image noise.
