Clear Type - Only in Landscape?
Greg Wilder
Is this ONLY for landscape, not portrait?
If you enable clear type for landscape, does it impact the quality
negatively for portrait?
Thanks in advance....

I haven't noticed any deterioration in portrait here, Greg, but this may be
a model by model issue. I'm sure others will report as well.

appears to work just fine here. Where did you hear the enabling only works
one direction? The display properties are driven by the graphics drivers,
not the orientation, as far as I can tell.

In a previous thread regarding the display being not as
sharp in portrait mode than in landscape mode, it was
written:
==========
Hi,
I bet that Cleartype is enabled on your Tablet PC. In
that case it,
Cleartype will only work in one orientation. This is
because of the way
that the dots that make up each of the colors are either
horizontal or
vertical. You can't have the pixels compatible with
Cleartype in both
directions.

On my Toshiba the ClearType configuration menu in Adobe
eBook Reader looks the same in portrait mode as
landscape. The Cleartype settings in MS Reader, however,
doesn't seem to look the same in portrait compared to
landscape mode. Go figure.

on the layout of the color pixels, have a look at the web site:

Nice explanation. I'm sure it answers several questions and in a way that's
easily understood.

I've forwarded your information to our engineers (but, our first Tablet does
not use this technology). Thanks, very useful info!
