Hi Ho,

The superframe must include two identical size images, so it is not possible. Note that 941AS may drive two different frame rates only in the independent 2:2 mode.

Best,

Josh

Hi Josh

Ignore the key word "super frame" above, there are 2 devices, instrument screen & HUD.

Is 941AS able to drive different resolution & refresh rate? Operating in "2:2 mode what you mentioned .

Hi Ho,

Yes, please see the Independent 2:2 Mode section (8.4.5) of the datasheet.
