I currently use an ASUS VH236H Black 23" 2ms(GTG) HDMI Widescreen Full HD 1080P monitor. Since I have had it an annoying issue has been happening with it. Whenever I move windows around on my screen or watch movies a line appears that flickers in the top of my screen. It is a horizontal line. Again, this only happens when moving applications that reach that top part of my screen or when a scene in a movie has camera movement in it. ( in a still scene this line does not show up. ) I am using 60hz and the native resolution. I am also using SLI with 2x 275 GTXs with the most up to date drivers with a DVI cable. This line has no color and seems to " split " the image of whatever it passes through. Example : when moving a window from one end of the screen to the other the line will flicker and cut the image so long as the movement continues. If I stop moving the window the line goes away. If I move the image to the bottom of the screen the line does NOT appear.
