if anyone has 3 screens, do these still work? i enumerated all the monitors and mapped the virtual screen space, so it should

 

What are they written in?

(for the matrix one)

 

Just a few api calls used then!

 

lunchtime projects don't usually stretch to directdraw and opengl and c++ is tediously slow to develop, so, how else do i get 50 fps at 2560x1024???


i didn't include the get monitor api calls.

the marquee one has about 15 more to enumerate the window processes too.

 

Matrix one doesn't work properly for me. Maybe due to my having my second monitor to the left of my main one, rather than on the right.

Anyway, the "Main" screen looks fine in preview, but the secondary screen just has a thin band of "matrixy" stuff on the right-hand side, but the rest of the screen still shows my workspace.

Regardless of the configured position of my second screen, if I leave my PC so it goes into the screen saver by itself, I get the following error: " Run-time error '384': A form can't be moved or sized while minimized or maximized", and a small rectangle labled "Form1" appears in the bottom-left of my main screen.

 

uhmm, i got that too!

windows must be having a tantrum.

i'll post when it's corrected.

 

new matrix version at the top.


works fine now
