Summary: I have had several of these monitors. I use a two-monitor set-up. - The backlight on the first burned out one month out of warrantee. ViewSonic would not replace the first monitor- fair enough as it was out of warrantee. I purchased a replacement. When it came, the screen was blue, and the color could not be adjusted. ViewSonic sent a replacement which had a green screen, and again, the color could not be adjusted.
Summary: I bought this from frys and am returning it today. Maybe it's only me, but mine had really bad quality and distorted images. I had 17" LCD monitor from viewsonic and was replacing it because it has similar problem. Now, 19" has same problem and I am done with viewsonic. I am not going to use viewsonic monitors again. Instead, I am going to try samsung ones.
