Monitor turn off just before logging screen

[mfex88]

Hi, i got a problem with yosemite and mavericks, both did the same thing.

The installation goes well and i can boot to the os with nv_disable. (i use a gtx 260 896mb).
if i dont use nv_disable=1, the monitor just turn off just before the logging screen.

I see that nvda50 is loading and registered or something like that just before it turn off.

my spec: Dell Precision t7400
2 cpu x Intel Xeon E5450 3ghz (quad core)
4gb fb-ddr2 memory
Nvidia GTX 260 896mb

i tried installing web driver just to test it and didnt work eather..
and i found that dvi to vga was maybe what cause this but i changed for a dvi-i to hdmi and still nothing
Thanks!
