    Why would 5x be cutting off a small amount of the left and right sides of the image into a 1600×1200 native res LCD? I’m testing with a Neo Geo.

    Are you using Generic 4:3 or an advanced timing?

    I’m using Generic 4:3. Should I try something else?

    Try setting H.samplerate to 1950 in adv. timing menu – if supported by the display, that fixes cropping and aspect. You could also try optimal timings for Neo Geo.

    Thanks for the pointers. Here are my optimal settings on Neo Geo:

    h.samplerate 1935
    h.backporch 138
    h.active 1600
    v.backporch 13

    This will need to change along with the PCB?

    Here are the rest of my non-default settings:

    TX mode DVI
    Line5x format 1600×1200
    240p/288p proc Line5x
    Scanlines Manual
    Scanline str. 50%
    Sl. hybrid str. 100%

    I’m open to suggestions. 🙂
