I know this problem has been answered before, but I could not make any of the presented solutions work for me.
I just bought a Phillips 245B monitor with QHD (2560x1440) so I could run it in native resolution with my MacBook Pro (15-inch, Mid 2010) and its NVIDIA GeForce GT 330M GPU.
Unfortunately the maximum resolution that IOS lets me choose is 1080p.
I tried already:
- Preferences -> Displays -> option-click on Scaled
- Resetting the PRAM
- A different Mini Display Port to HDMI adapter (from Gravis) and a Mini Display Port to display port adapter, which resulted in a "no video output" on the monitor.
- Creating a new EDID file like here, which resulted in the monitor staying black.
I hope one of you guys can help me :-)
