yes ... the elsa 3d revelator is vesa compatible but the vesa standard stated that it has 5v not 12v .
I learned that sgi pushed this standard .... but vesa changed it so it powers with only 5v.
Sgi had on all types of connectors for the 3d glasses a voltage of 12v 0.5 amps.
Now i have an asus 3d glasses and this elsa .
For the asus i will try the old project tot adapt the sync and voltage.
But for the elsa all i could think of is that it should work even if the voltage is much than twice ... it's low amp anyway.
About the vga cable ... yes you are right ... the elsa glasses is connected through a vga splitter ... an it draws 5v from vga ... the sync is ovelapped on the ddc signal and the nvidia driver know's that .
Now ... digging thorough the net i found out another great project that will make both of them work in any configuration ... a controller in two versions ... analog and digital with it's share of pros and cons ... this is the link http://www.nord-com.net/cnb00957/index_frames.html
Thank you for the suggetsion on how to check the presenter mini-din signal ... i'll try that ...
If i'm gonna hit something interesting with this project i'll put it here.
By the way somebody "Voralyan" said that elsa revelator works wihtout any adapter but he had an octane ... i don't know ...
