Using a 65545 to control an LCD, with the following libvga.config: HorizSync 31.5 35.1 VertRefresh 50 70 chipset VESA The display is set to G640x480x256, with the LCD displaying the upper-left 320x240 pixels. The problem is that images are offset from where they should appear. The top two rows are lost, and two blank rows are displayed at the bottom. The left 4 columns are blank, and the corresponding columns are lost from the right side of the image. Svidtune reports: Clock 25175 HDisplay 640 HSyncStart 664 HSyncEnd 760 HTotal 800 VDisplay 480 VSyncStart 491 VSyncEnd 493 VTotal 525 flags 0 = Horz freq 31.459 KHz Vert freq 59.94 Hz Making changes via svidtune and putting the modeline into libvga.config makes no difference. The VESA driver doesn't seem to make use of the modeline. Can somebody tell me what registers need to be changed to fix this? Thanks. -- _ Kevin D.
