Aspect Correction Mode
A major difference between CRT and LCD monitors is the shape of their respective pixel arrays. CRT monitors use a
non-square array, while LCD displays adopt a square-shaped array. Aspect Correction Mode is a technique used by LCD
displays to overcome this difference and emulate the look of a CRT image. Using a scaling technique, this function arranges
the SD input signal to emulate the CRT's non-square pixel array in a horizontal direction. It also applies the appropriate
scaling algorithm depending on the video format, NTSC or PAL. An interlace display mode can also be applied when
necessary, enabling the monitor to reproduce familiar-looking SD images.

Native Scan (pixel-to-pixel display)
Conventional flat panel monitors reproduce images using scaling and I/P conversion due to their fixed pixel counts and
progressive scanning processes. The Native Scan function equipped on the PVM-L2300 is a unique display mode that reproduces
images without changing the input signal's pixel count. For example, when an SD signal is input, the PVM-L2300 will reproduce the
image at a picture size of 720 x 487
to be doubled to 1440 x 974
