Hello everyone,

I want to use a 1280x120 display (16bit parallel RGB interface) with a STM32F469.

The datasheet says that it can only support a maximum resolution of 1024x768.

The horizontal resolution of my display is a bit higher, but my total bandwith schould be much less, because the vertical resolution is so low.

Is it possible somehow?

Thanks for your help,

Moritz

Probably, its a matter of total memory size, bandwidth, and width of control registers. If you don't violate the first two, it will come down to the last. Make sure there is a >10-bit register describing the width of the screen raster.
