Query: excellent LCD

with so low price, i can not believe that I can buy so good an LCD. it is so worth it. very clear and crisp. the viewable screen is wide.easy to set up.The Autoadjust fuction makes it very easy to set the LCD to it best performance.The only problem i can find now is that some times during screen saver, it becomes blank,just leaving some lines on the screen, without any other images.I do not know why.but if you use autoadjust fucntion, it becomes Ok instantly.
