I often uses screen flashing in my aesthetic, ALPHA
are figuring this.
I struggled to have flashes synchronized with the rendering engine.
Actually, I used this and since years. it does the job well. Theoretically, it shouldn't, from a strict point of view, but it does.
BUT, the problem is the display. In practice, sometimes it goes very well, and sometimes it is not bad but not totally ok.
I got the fact of asynchronous flow of operations: the rendering engine is ok, it sends a flash, very short, and if the display (screen, videoprojector) got the display loop not completely sync or fast or whatever, the flash is not seen properly well.
Touring, you never get the same kinf of display, so it has to be testest, adjusted (?) and checked at each show.
Increasing rates helps.. of course (even if the sync problem is not solved, getting faster pratically decreases it, actually it increases the luck of having things like synced)
My question to you: how would or do you manage this ?
Any ideas or suggestions would be very interesting for me :-)
