Last night when I shut my Lenovo, Windows 7 Professional, desktop down everything was running fine, however, this morning when I started it up, there is a black band, about 1/2" wide at the top and bottom of my main monitor. I run dual Acer monitors, an AL1906 & an AL1916. The bands are on the AL1916. I tried pushing the buttons at the bottom of the monitor to see if there was any way of adjusting the screen, however, if it is there, I couldn't figure it out. The monitors are probably from 2006 & 2007 and are used nearly everyday for at least 12 hours a day. I don't know if this is a problem that could be a sign of it getting just plain old & tired or if downloading a driver for it would put it back to normal. The Video Card is a NVDIA GeForce GT 430 that I installed when I got the computer about 8 months ago as it did not have dual monitor capabilities. Thank You,
