Hey, in store I was checking out modes for this samsung monitor, and i saw a tab called "RTA" it had options "Off, 1, 2" I switched between 1 and 2, on the 2nd mode when it was doing its slideshow of pictures the picture would skip and jitter when fading to next, on 1st mode it faded normally.

Just wondering what it means and stuff' :eek:
 
RTA over-volts the pixels so that they can change colors faster. This helps improve response times, however it can cause issue like what you have seen for yourself.

When a pixel is over-volted the pixel can and will over-shoot the color it is supposed to display. For example, let's say you are playing a game and in a particular section of the screen is a blue wall, then you move your character wearing dark red armor. RTA will cause the pixels to overshoot a bit, instead of displaying "dark red" it might show a "medium red" and/or perhaps a different hue of red because the over-volting affects the sub-pixels which acts in unison to create the proper color.

Additionally, it can create a ghosting effect because over-volted pixels can cause an image (color) to stay lit longer. Theoretically speaking, the higher the voltage applied to a pixel, the longer it will take the voltage to drop to zero (or whatever the correct voltage should be) so that the pixel can revert back to black.
