    Hi,

    in the manual of my new TFT screen I have the table:

    Display Mode Hori. Sync Vert. Sync Pixel Clock
    1280x1024 48.363 60.004 65.000
                            56.476 70.069 75.00
                            60.023 75.029 78.750
    1280x1024 63.981 60.020 108.000
                            79.976 75.025 135.000

    My current /etc/X11/XF86Config-4 says:

    Section "Monitor"
            Identifier "Monitor0"
            Option "DPMS" "true"
            VendorName "HWP"

    # VertRefresh 50.0 - 62.0 # Extreme conservative. Will flicker. TFT default.

            # Extended modelines with GTF timings
            [...]

    How should I modify the config file to get best performance with my screen?

    Thanks
