max resolution...?

Hi, I'm looking at using the beadle board for a project where I
require the output res to be set to 3216x1920. This is for a custom
bit of hardware which has a funny res. I'm looking to use the beagle
board just to display a couple of images nothing fancy. Do you think
its feasible?

Cheers

Luke

No. Max in theory is 2048x2048 for the BeagleBoard-xM…

That's bigger than the maximum resolution supported by the DSS.

And the built in video controller will do a maximum resolution of 1400x1050 at 50 Hz refresh rate.

The 2048x2048 is the “maximum” video surface (you can scroll the screen around to display a “viewport” into this 2048x2048 surface), but the video DAC hardware is restricted to the 1400x1050 50 Hertz vertical refresh rate, 32 bits per pixel layout.

Nonsense.

Video DAC? I always thought it was 24b RGB digital.

There's isn't even a DAC on the beagle ... it's all digital.

Well, there is the s-video output...

ah well, thanks for taking the time to reply.

Looks like my only option is a small embedded PC then.

OMAP3/AM37x (so BeagleBoard XM) has inbuilt DAC available as part of DSS.

Thanks,
