Mohl by jsi ten monitor projet jeste inversion testy, ktere jsou na http://www.techmind.org/lcd/?

Je tam tech vzoru trochu vice a IMO by se to melo projevovat na kazdem LCD uz z principu funkce - jde jen o to trefit vzor, podle ktereho se polarita pixelu prepina viz:

In liquid crystal pixel cells, it is only the magnitude of the applied voltage which determines the light transmission (the transmission vs. voltage function is symmetrical about 0V). To prevent polarisation (and rapid permanent damage) of the liquid crystal material, the polarity of the cell voltage is reversed on alternate video frames. Unfortunately it is very difficult to get exactly the same voltage on the cell in both polarities, so the pixel-cell brightness will tend to flicker to some extent at half the frame-rate. If the polarity of the whole screen were inverted at once then the flicker would be highly objectionable. Instead, it is usual to have the polarity of nearby pixels in anti-phase, thus cancelling out the flicker over areas of any significant size. In this way the flicker can be made imperceptible for most "natural" images.
Cau,

viditelne mi zrni pouze Line-paired RGB sub-pixel dot-inversion (offset), a trosicku asi Line-paired dot-inversion (green test)-offset. Jinak V pohode, spis je neprijemny na ty obrazky koukat.
