I recently purchased an Asus VH238H which was on sale and is LED back-lit. Shortly thereafter, I began to notice these faint vertical lines mostly down the middle of the screen, only in dark scenery. It could be in a movie or a game, or simply a dark background; point is: anything dark or black, these lines are noticeable.

I have attached a few pictures of the monitor on a black surface (although the quality is poor), in hopes someone could enlighten me as to whether I should send it back to the manufacturer or keep it. My understanding is that this may be something called "flashlighting", but I want to make sure, as I'm not one to throw money out the window.

Any help is greatly appreciated.

Does it still occur when you change resolutions?

Very interesting; I switched the resolutions around a bit and 1680x1050 not only gets ride of the problem, but also seems to make the colors truer, which leads me to believe the LED backlighting isn't enabled at 1920x1080.

EDIT: It doesn't get rid of the problem, it's just darker so I can't see the lines as much. They still exist.
