Thanks for the tip. But why have all FP modes 160 MHz? Does this make sense? How can I then get to lower resolutions? If I use CRT as display mode the Xserver starts in 800x600 mode, unfortunately the TFT screen stays blank. I suppose that this mode is then displayed on the CRT output (can't check at the moment).
