i could be wrong (because i havn't used 2 cards for a long time) [i prefer scanconverter when going out with gem]
rendering opengl on secondary display DIDN'T work @ me with: disp1: some cheap s3 card (primary) disp2: nvidia tnt2 (secondary) (but if i changed the disp2 as primary it worked)
but with 2 SAME cards it should go on both (i've heard from newsgroups)
but if you have a card with 2outs (like, some nvidia&matrox) theres openGL on BOTH outs automaticly...
if there's some1 who actually 100% KNOWS what are the issues on opengl on secondary display, please let us know...
cheers -andre

this is quite strange, under windows 2000 I can run my gemwin on a secondary display without a problem. I do recall a case when I friend (running XP) with the Nvidia GO on a laptop could not render on the second display. I'm not sure what the pattern is.
good luck. Ben

FYI:
nVidia released a new driver a few weeks ago which, based on their
documention, seems pretty incredible. I'm trying it out right now because I thought it might solve a problem I was having rendering GEMwindow on a secondary display. In any case, it seems worth the upgrade.
I went looking for a driver update because I couldn't figure out why my
GEMwin wouldn't display all my cool video and eyecandy on my secondary display...then I found a note in the pd-list archive written by Andre S. a few months ago:
"and remember, when using 2 cards on windows, only card1 (primary
display) uses directX/openGL"
ahhhh....NOW it all makes sense.
Thanks Andre, Regards, Dave Sabine.
