So, when used for PC, it always selects the best resolution, and it can not do that for the embedded device, for the reason of 7" LCD display supporting the most high resolution is 800X480, if both of them can not match well, the display will not be normal. so is there one way to automatically match them, adapting to 800X480, not the higher?</div> <br></div> <div class="gmail_quote"> <div class="im">2009/4/24 John Yoder <span dir="ltr"><<a href="mailto:jtyoder@twny.net" target="_blank">jtyoder@twny.net</a>></span><br></div> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div> <div>On Wed, 2009-04-22 at 14:20 +0800, wan michael wrote: <br></div> <div> <div></div> <div class="h5"> <blockquote type="CITE"> <div>hi<br> <br>can the geode driver provide the mode 800x480? if so, it can meet the 7' LCD display which is 800x480, and not the standard modes on pc.<br> <br> </div><pre>_______________________________________________ Xorg-driver-geode mailing list <a href="mailto:Xorg-driver-geode@lists.x.org" target="_blank">Xorg-driver-geode@lists.x.org</a> <a href="http://lists.x.org/mailman/listinfo/xorg-driver-geode" target="_blank">http://lists.x.org/mailman/listinfo/xorg-driver-geode</a> </pre></blockquote>It should be able to provide the 800x480 mode. However, that will require a custom modeline in the xorg.cong. I would use one of the modeline calculators as a starting point. Whenever I need to provide custom modelines it takes a bit to get the dot clock frequency of the LX and Monitor to be correct, but not typically much of a problem.<br> <br>Best Regards,<br><font color="#888888"><br>John Yoder </font></div></div></div></blockquote></div><br></blockquote></div><br>
