or just <br />
if (window.screen) ColD = screen.colorDepth;<br />
colorDepth in N4 isn't adapted for that purpose, returning<br />
the # of bits available for composing a palette<br />
color mode:_256_64K_16M<br />
pixelDepth:___8__16__24<br />
colorDepth:__18__16__24<br />
<br />
'scuse the formatting<br />
<br />
so a the better test would be<br />
<br />
if (window.screen) {<br />
&nbsp; &nbsp; &nbsp; ColD = screen.pixelDepth <br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;? Math.pow( 2, screen.pixelDepth ) // in N4<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;: Math.pow( 2, screen.colorDepth ) // in E4<br />
