Subject: Re: Multiple display support

Hi,

just to drop in my few lines : I did something in this direction once this year, for the 100h of astronomy star party : C8 + webcam + AstroIIDC + beamer + a huge 4x3 meter screen with the Moon at 30fps :-) I'm really rather against high-tech instead of simple-eyepiece-viewing in the case of star parties, but in this case the result was simply awesome ! One hand on the telescope control, and a laser pointer in the other hand to show surface-features on the big screen...

What I did is to turn off display-mirroring, put AstroIIDC's preview window on the beamer while keeping the control window on the laptop screen, hiding the dock, and setting the beamer to a very low resolution (... 640 x 480, thus keeping the AstroIIDC zoom at 100%). Well I still had that menubar on the beamer, but otherwise it was perfect. (actually I even used multiple desktops to switch between a moon chart and live view etc... plus you can get a black menubar by using the negative-image setting in the system prefs.

Extemely important here is the framerate : I experienced that I couldn't get a fast live view using AstroIIDC's own zoom and keeping the beamer's resolution at native value. And for such presentations, all the pleasure really comes from the faster-then-turbulence framerate...

Cheers,

Malte
