This question is probably just because I misunderstood something you said before, but I'll ask anyway :)<br><br>If it is acceptable to use QVGA, couldn't that basically be done without any hardware changes? I believe I remember you saying the glamo does scaling, so couldn't you let SW treat the display as qvga, and just have the glamo scale it up?<br>
<br>Or, is the question more about having qvga instead of the glamo (which leaves you back with the SDIO interface shortage)?<br><br>--Steve<br><br><div class="gmail_quote">On Thu, Jun 5, 2008 at 10:42 PM, The Rasterman Carsten Haitzler <<a href="mailto:raster@openmoko.org">raster@openmoko.org</a>> wrote:<br>

<br>
qvga is 320x240. wqvga... that's a whole world of resolutions (400x240,<br>
432x240, 480x272, 480x320). :)<br>

but it's not a drop-in replacement as its widescreen. we c ould go for 2.8" vga<br>
or 2.8" qvga. drop-in replacement. anything else mans new case/design etc. etc.<br>
<br>
also remember just getting supply of a screen is hard. you also need it at a<br>
decent physical size.<br>
<br>
i'm asking the question if going down to a (relatively) low resolution screen<br>
would be an ok compromise.<br>

<br>
one way or another we will need to be able to do multiple resolutions in the<br>
long-run.<br>

<br>
again - it depends what you want to do. :) gta01 actually performance better in<br>
many ways graphically :)<br>
