I have a ViewSonic PF790 that I bought about a year ago. Last night the screen was noticeably expanding depending on how much black or white is on the screen. I know that a slight contraction and expanding is normal for monitors, but this was very dramatic, almost a full inch. The more black that was on the screen the more it expanded and the more white on the screen it would go back to normal. Also I noticed when there was more black on the screen the color of the screen changed a little. Has anyone seen this before?
I have a feeling it has to do with the power supply. It seems to go away if I turn the monitor off and then back on, but after a couple minutes the problem comes back. Thanks in advanced for any help or knowledge of this.
