Yosemite and analog monitors Apple Studio Display

With Yosemite issue I found that only 2 monitor resolutions are possible to setup through System Preferences. You can change this limited option with Display Maestro or other way you can find.

But I want to fix this problem editing the EDID configuration, but after creating and installing in S/L/Displays/Override/ a folder with the Apple ID monitor, the trick does´t work and I think its cause Monitor and video card are not speaking the same language ...

Does anyone has identifiers for a Apple Studio Display 17" analog (CRT) blue ??

Video card is a Zotac (Nvidia) GeForce 9500 GT 1024 MB, (VDI and HDMI ports)

On System profile, Yosemite identify this monitor as digital (!) which it is not the case ...

Thank you for any help!
