15 Bpp Video Mode

[zzhu8192]

I've looked through the wiki and some docs, and did not see any info on this.

Does anyone know whether:
1) gp2x supports 15bpp video mode natively? i.e. no software conversion.
2) if so, how to set this?

Thanks.

No software conversion? WTF are you talking about??? The gp2x supports it natively... But why the hell and for what would you want to "set" this? I don't understand where you are getting with that... do you want to know how to set up a graphical environment in sdl or something?

RGB layer supports 4, 8, 16 and 24 bits per pixel.
Not 15.

16 bpp uses 6 bits for green as usual.

ah! So that's what he meant...

Thanks for the constructive reply.

Note that even though the lcd controller supports 24 bit, the LCD itself doesn't - it supports upto 18-bit (RGB666) which the LCD controller doesnt :s

If the LCD doesn't support 24-bit mode, maybe the TV-Out does?

Quite possibly, and could be the reason why the controller supports 24-bit - for decoding movies...
