<p>My solution so far:<br><br> I reduced (in Display
Preferences) the projector's resolution to 640 x 480. I correspondingly
changed the gemwin dimensions to 640 x 480.<br><br>Since I was hitting
some kind of gemwin dimension limit around 700 pixels, PD now outputs
an entirely coloured screen on the projector-side of my virtual desktop... and that's what I want :)<br><br>I'm
still curious as to why I couldn't to have a gemwin larger than 700
x700 on my virtual desktop...... ung ung ung... and I feel like I've done a 1024 x768 projection outta PD before..... I actually came up against
the same issue in MAX 5 (yes, I re-made my PD patch in Max 5) <br></p><p>hmmm.... well it works now!<br></p><p><br></p><p><br></p><p><em></em></p>
