Vertical lines on desktop

[jjlacatel]

Greetings. New user here with desktop display problem.

I have 2 stationary thin vertical lines (1 blue, 1 white) which consistently appear at the end of re-booting and have been unable to determin which application is the cause.

I use a variety of photos as a desktop, but have the lines even without a custom dt image. My only new startup application since the lines first appeared is ScanSnap / CardReader for a Fujitsu document scanner; however I have this software installed on several systems and only one is having the vertical lines appears.

Any suggestions for trouble shooting? Thanks.

Is this a Trinitron monitor?

The monitor is a Dell 19" LCD. I have the same ScanSnap programs installed on another Dell with a different 19" LCD (x2gen, which is a nice monitor for the price) and do not have the lines.

Ahh my mistake, the old Trinitron CRT monitors had 2 horizontal lines. You said vertical. My bad. Im just throwing this out there but all LCD monitors operate at no more than 60Hertz. Under your Display Properties double check that the refresh rate is at 60 and no more. A total guess to your problem but I have seen some odd artifacts on machines that have higher rates set.

It does sound like a weird problem. I take it you don't get the lines while Windows is starting up, only when it gets to the Welcome screen or the desktop? That would indicate they're only appearing when your resolution changes.

First off, make sure your resolution is set to your monitor's 'native' resolution - this should be listed in the manual or on the maker's web site but it's probably 1280 x 1024 for a 19" LCD. Secondly, update the drivers for your graphics hardware, i.e. your graphics card if you have one or your on-board graphics if you don't. They could somehow have become corrupted.

Well I feel a little stupid but I accidently discovered what caused the vertical lines.

Apparently when I last changed my desktop (new photo) I somehow created two additional desktop windows that had normal height but horizontally were reduced to about a 1pt. line.

I was going through restore points trying to determine closer when the lines first appeared and I accidently parked the mouse pointer over where blue line while the system was still booting and it expanded to about a half inch wide. I then just expanded it until the window controls where visible and closed it. Same with the other one. Sorry for the operator error and thank you for your time and assistance.
