Taj model Lg nikad nisam video.
Ali zato taj PHILIPS jesam.
I mogu ti reci da sam prilicno zadovoljan njime.
Full hd,touch paljenje i komande.
Lepog dizajna.Nema primetno probijanje svetlosti.
Takodje mozes i da pogledas Philips 220E.Istih karakteristika razlika je samo u dizajnu jeftiniji je nekih 500din.

M.P.

Ok, hvala.

A sta znaci ono 10.000:1 odnosno 8.000:1 ? Skuplji imaju i 50.000:1.

Ja imam Samsung 710N
Kod njega je kontrast 800:1
Ja iskreno nevidim razliku izmedju 800:1 i 8000:1.
Jednostavno je neprimenta za oko.
E sad da li je to neki marketinski trik ne znam,bolje ce ti objasniti neko ko se razume u ovu tematiku.
Naravno na kraju izaberi monitor uzivo trazi od prodavca da ga prikljuci i da vidis kakva je slika i da li ima mrtvih piksela kakvo je probijanje pozadinske svetlosti.

Te "desetine hiljada naprema jedan" se odnose na tzv. dinamički kontrast (prilično neprecizna kategoruja)

Wikipedia: Contrast Ratio

Citat:

Dynamic contrast ratio
A notable recent development in the LCD technology is the so-called "dynamic contrast" (DC). When there is a need to display a dark image, the display would underpower the backlight lamp (or decrease the aperture of the projector's lens using an iris), but will proportionately amplify the transmission through the LCD panel. This gives the benefit of realizing the potential static contrast ratio of the LCD panel in dark scenes when the image is watched in a dark room. The drawback is that if a dark scene does contain small areas of superbright light, image quality may be over exposed.

The trick for the display is to determine how much of the highlights may be unnoticeably blown out in a given image under the given ambient lighting conditions.

Brightness, as it is most often used in marketing literature, refers to the emitted luminous intensity on screen measured in candela per square metre (cd/m2). The higher the number, the brighter the screen.

It is also common to market only the dynamic contrast ratio capability of a display (when it is better than its static contrast ratio), which should not be directly compared to the static contrast ratio. A plasma display with a static 5000:1 contrast ratio will show superior contrast to an LCD with 5000:1 dynamic and 1000:1 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.
