Highest resolution possible with HYDRA

I am a newbie to the chip and to this forum. But I've done fair amount of embedded programming with LPC2138 chip and now considering Propeller chip for a graphics app where text and some graphics need to be overlayed over video signal (OSD). A question to experts: what's the highest resolution possible with the chip. I.e. if RAM size is not a problem, is it possible to drive XGA (800x600) display with it? What about 600 horizontal pixels in NTSC?
Thanks!
Thanks!

NTSC is a different matter. The limitations there are in the video format. You can't realistically get 600 horizontal pixels and only 225-240 vertical lines.
· There is some NTSC OSD code I wrote in the Propeller object exchange.

Looks like I am ready to do the plunge.
The overlay project is exactly what I am looking for, but may be with higher resolution. I only want to·overlay borders of the screen,·~20% of total·area,·so there should be enough RAM to support it. I am sure will have more questions later. But for now I just order the board and read up the docs.
