My first two guesses would be a video driver problem, or a hardware problem with the video card.

First thing to do would be to  see if you can locate a newer driver.

Looks like a scratch to me

Thank you two for reply. it is not scratch because it can move on the screen. in fact it is not big issue, but when i screen copy, i notice the mark also can be copied too : ) it might be driver issue or something else

Since it's the second monitor, try switching them to be sure and see if the mark stays in the same place, or follows the monitor.
