Does it have digital signal processing for anti-aliasing, and edge-detection? Must have cost a bundle! :-) (Of course, the "focus" might be out so that you light up more than one pixel at a time.) Take a _very close_ look when the weathermap is displayed. The isobars are usually narrow enough ( < 2 pixels ) to cause small amounts of flicker. This will of course only be noticeable on long horizontal sections of the lines. You may occasionally see the effect in low-cost video productions, when computer-generated graphics are displayed. Sharp edges in the colours, which have not be aliased, will flicker. Flicker will be evident when adjacent screen pixels in the two display fields are *significantly* different, and being updated at less than about 50Hz. (The exact frequency depends on individuals.) >matt crowd. -- _--_|\ Bernd Felsche #include / \ Metapro Systems, 328 Albany Highway, Victoria Park, Western Australia \_.--._/ Fax: +61 9 472 3337 Phone: +61 9 362 9355 TZ=WST-8 v E-Mail: bernie@metapro.DIALix.oz.au | bernie@DIALix.oz.au
