If you can afford the 24 MHz clock (and if it works with your panel) it will give you a perfect 60.0 Hz refresh rate, while this mode above will give you above 59.93 Hz (which is not that bad though). Otherwise LGTM.

OK, why not use the leadtek's initialization sequence then? From what I can see, you have a panel with a NV3052C chip, so the existing initialization sequence should already work. > > > Did you try with the existing display modes?

The NV3052C datasheet does not give any settings for a 640x480 panel, I only see suggested settings for a 720x1280 vertical panel. Unless you have a min/max range specified, the values you see in there are only suggestions for a working setup, that doesn't mean they are the only recommended ones. Cheers, -Paul

Again, doesn't mean that you have to use these. From what I can see, all you need to support your Fascontek panel with the nv3052c driver, is to add the SPI ID and compatible strings. Cheers, -Paul
