It is likely that the LCD Projector is a standard 4:3 video device (this is implied by being a VGA device) and is not going to handle a (near) 16:9 (wide screen) video mode. Unless the LCD Projector is really, really, really old, it should handle 1024x768 without problems. > > On Sun, Sep 11, 2011 at 9:25 PM, Robert Heller <heller at deepsoft.com> wrote: > > > At Sun, 11 Sep 2011 20:34:30 +0700 CentOS mailing list <centos at centos.org> > > wrote: > > > > > > > > > > > and this is my xorg configuration : > > > Section "Device" > > > Identifier "Videocard0" > > > Driver "openchrome" > > > EndSection > > > > > > Section "Screen" > > > Identifier "Screen0" > > > Device "Videocard0" > > > DefaultDepth 24 > > > SubSection "Display" > > > Viewport 0 0 > > > Depth 24 > > > Modes "1280x800" "1024x768" "800x600" "640x480" ^ This is probably the problem ___| > > > EndSubSection > > > EndSection > > > > > > Hope you guys can help me.
