Query: ViewSonic P220f 22" Flat CRT Monitor

Don't expect a clean screen on this monitor. It will come with visible horizontal lines 1/4 and 3/4 of the way down from the top of the screen and they are annoying when you have a light background or a dark background. If your background is black they may not show. Don't spend your money on this monitor. I was very diappointed for the price I paid. ViewSonic says this:Two faint horizontal lines on my monitor screenThe two lines you see are called horizontal damper wires. These damper wires are required to maintain the aperture grille's alignment and will cast a shadow on the screen. In most applications, these lines will blend into the background, but they will be visible against lightly-colored screens. They are an integral part of the technology and are not considered a defect.Why doesn't ViewSonic disclose these lines in the specs?
