Contrast values obtained from two subsequently displayed full-screen patterns may be different from the values evaluated from a checkerboard pattern with the same optical states. That discrepancy may be due to non-ideal properties of the display-screen (e.g. crosstalk, halation, etc.) and/or due to straylight problems in the light measuring device.
An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...
The picture shows among other things a nice red flowing collar-like structure just below the anther. However, an intact thale cress stamen does not have such collar, this is a fixation artifact: the stamen has been cut below the picture frame, and epidermis (upper layer of cells) of stamen stalk has peeled off, forming a non-characteristic ...
Very nearly 3:2 (to within 0.2%); 256:171 exact. Displayed with square pixels on a moderately wide-screen monitor (equivalent to 16:10.67 in modern terms). 1 bpp: Hercules: A monochrome display capable of sharp text and graphics for its time. Very popular with the Lotus 1-2-3 spreadsheet application, which was one of PC's first killer apps ...
Deinterlacing by the display, and telecine processing by studios. These processes can soften images, and/or introduce motion-speed irregularities. Compression artifacts, present in digital video streams, can contribute additional blur during fast motion. Motion blur has been a more severe problem for LCDs, due to their sample-and-hold nature.

Playing back interlaced video from a DVD, digital file or analog capture card on a computer display instead requires some form of deinterlacing in the player software and/or graphics hardware, which often uses very simple methods to deinterlace. This means that interlaced video often has visible artifacts on computer systems.
If an LCD is subjected to physical shock, this could cause one or more TAB connections to fail inside the display. This failure is often caused by horizontally flexing the chassis (e.g., while wall-mounting or transporting a display face up/down) or simple failure of the adhesive holding the TAB against the glass.
As an inherently digital device, the LCD can natively display digital data from a DVI or HDMI connection without requiring conversion to analog. Some LCD panels have native fiber-optic inputs in addition to DVI and HDMI. [155] Many LCD monitors are powered by a 12 V power supply, and if built into a computer can be powered by its 12 V power supply.
