ghosting problem on Samsung 931bw LCD [caused by RTA]

The 931bw is rated at 2ms refresh, but there are clear ghosting issues:
1) In the 1st part of video (slowed down by 4x), the word "description" has ghosting above/below the word during mouse scrolling. The gray area behind the text has slight ghosting at the edge too.
2) In the 2nd part, the gray bars behind the text have the problem. During scrolling the edges of bars would darken, giving a reddish tint.

Such issues have been reproduced by numerous users and is not related to the video card or DVI-D or VGA cables.

It is caused by the "RTA" setting (credit: user McGuywer). Unfortunately it is re-enabled each time you turn off the monitor. Suggestion to Samsung: fix RTA or allow it to be turned off permanently.

you just think this caused by this RTA or something. this is definitely GPU-problem.

no, it's been tested. Two LCDs, same GPU, only Samsung's RTA caused this. Read the comments.

thats rather a vga problem than the monitor's.

[anon69]

This is caused by the monitor's RTA option. Please read the comments.

RTA, Press Menu, Choose the one with 3 bars, you know, like an equalizer, choose RTA, then disable it. i hate it by the way, the games looks like 20fps with it enabled

For the newbie who did this video:

There is ghost because it is from black to white or white to black. The time measured of 2ms isn't measured from those 2 extremes.

Now you know noob!

"Fixing" the RTA would be to adjust it to more passive, which would result in a response time far above 2ms.

Without RTA at all, this screen would have a response time above 10ms.

Now you know.
