VGA to RF coax

[emilianomorgia]

Is it possible to use this adaptor (second output) together with dvi-vga on the first output for monitoring purpuses during rehearsal (reprogramming)?

Wouldnt i be better of with composite?

Can i mix RF tv's with composit tv's without seeing the difference in image quality?

Thanks again!

i'm on a show rightnow . Mac pro 3 Giga xt1900
first output 1024x768
second apple video adaptor ....

The good news is I've switch from a FOLSON converter ( 3000 euro ) to the video adaptor ( 19 euro ) with no different on the final result
