Ahh. I tried increasing the 32bpp number to 150MHz, and was successfully able to use a mode at 135MHz. I am confused as to why the Pixmap setting affects the ramdac frequency. Is this a mistake or am I misunderstanding something? Would it be okay to set the maximum based on depth instead of bitsPerPixel, or is bitsPerPixel wrong if it's set to 32 at a plain 24-bit depth?
