#33 TwinView - Aspect ratio problem

[Uli Laube]

Hi!

I have a dual head system using an Nvidia Gfx-card in
TwinView mode, that is the Nvidia driver module does
not tell the X Server that there are two displays, it
pretends that there is only a big one, in this case two
times 1280x1024 makes it 2560x1024 wide. Altough this
results in an aspect ratio of 5:2 the pixels are still
square.

Klear however gets confused and scales the picture as
shown one the attached picture "dual.jpg".

If I disable TwinView I have 1280x1024 that is a single
5:4 screen, then everything seems to bee alright. As
shown on the attached picture "single.png"

By the way, Adobe Acrobat Reader 7.0.1 seems to have
the same problem. Other DVB-Viewers however (Kaffeine
etc.) are not affected be the TwinView-Mode

Kind regards

Uli

Hi I have the same Problem
Perhaps someone can tell how to Overide the Resolution
determined automatically
Is it possible to set it by Xdefaults??

(For Adobe change Preferences /Page display/Resolution to
custom Resolution 72 Pix/Inch and it works fine
