I found some websites still have the following footnote at the bottom of a page:
"This site is best viewed at 1024x768 screen resolution with Internet Explorer 6.0 SP2 or above."
The above footnote is absolutely not necessary. Today, people are using 19 - 22 inches LCD with 16:9 aspect ratio. Some larger monitors have 22:10 ratio. 1024 x 768 is considered as a poor resolution using the old traditional 4:3 aspect ratio.
Just take away the fucking advice and users will know how to adjust their monitors and video display to achieve the best viewing effect.
