ja isto imam pun k... bleedinga na donjim kutovima

Koliko sam vidio po forumima kada sam tražio bolji 20" LCD većina monitora ima malo ili ako nema dobije s vremenom, nažalost mana LCD tehnologije.

LCDs can not display a true black due to some technical reasons. Black level is a measurement of how much light is let through when black is requested, and it is usually measured in candelas per square meter, the same unit as a "nit". When the black level is above zero nits for an LCD, light is said to be leaking or bleeding. LCDs, not unlike other technologies, can suffer from screen uniformity problems. Light may leak more in some areas of the screen than others. Often, it leaks more around a couple of edges (the notorious "backlight bleeding"). When light bleeds, black will look a dark gray or bluish-gray, depending on the backlight's color temperature.

Black level and light leakage can depend on several factors, including LC (liquid crystal) mode/arrangement (e.g. PVA, TN), cell gap, polarizer quality, and thermal fluctuation within the panel. Backlight bleeding can also be caused by pressure on the panel that goes away after a week or so, like in the case of the NEC 20WMGX2. In the right situations (a bit of ambient light), a glossy coating can improve the perceived black level. Most LCDs reach a black level of 0.20 - 0.60 nits, while maintaining a white level from 120 - 220 nits. Uniformity highly varies, although Grade A S-IPS panels made by LG Philips tend to have great homogeneity and a small amount of light leakage. Conversely, the 22" TNs from Chi Mei are known to have a lot of bleeding at the top and bottom of the screen, but, for many, this can be justified by the latter's very low price.

Ja do prije dana nisam imao niti malo, velim onda kada se pojavio stisnuo sam masku par puta u tom području i još sam prstom(ali ne vrhom) malo "izmasirao" taj mali dio di se pojavilo i sada nemam ni kad ga "svježe" upalim.
