When i changed my old monitor with ViewSonic VE155B Black 15" LCD Monitor, the beautiful pictures previously stored on my computer appear too dark. i checked the settings of monitor, but the brightness n contrast both r maximum. What shall i do to fix this problem? Thank you, Rubina.

Rubina576, I see you haven't looked at the "date of manufacture" on rear of your VE155B!!!! Retrevo .com lists unit as time to retire. The long,"very thin", "cold-cathode-fluorescent-lamps" that provide a "constant" bright, "white light" on the reverse side of the LCD PANEL, have "worn out" and are very "tired"!!!! You can see typical lcd CCFL's at: www.rexim.com and click on "products" you will see "lcd backlights" !!! YOU ARE NOT QUALIFIED TO CHANGE THEM. A technician will need to do it. Very time consuming procedure. If your ve155b menu button on monitor can't fix brightness for you, then your options are: 1. check with viewsonic to cost out a refurbed VE155b if you can. 2. Trade in unit for new wide-screen 2010 or 2011 lcd monitor. If this was of some help, please rate my response on fixya. By for now. 12fixlouie north of Windy City.
