Hey,

 

I've an EVGA Titan X on 365.10 drivers, same happens with a factory DP cable and another one I have (same length), G-Sync is enabled, OD is set to Extreme.

 

Only options available in the Nvidia CP is 50 and 60hz, same in Windows display settings. 

 

Monitor's Function Menu, under Information I see:

Information
Resolution             3440x1440
Max Refresh Rate  60 Hz
Mode                    NVIDIA G-SYNC

 

I've tried turning the monitor on/off. I tried forcing a customized resolution via the NVCP with as low as 70hz, no luck, either.

 

I'm not sure what am I doing wrong. Any ideas?

 

Thanks!

    I found out I'm supposed to unlock the higher refresh rates via the "Over Clock" menu, I thought I was supposed to set the "OD (overdrive)" to Extreme.

     

    I've successfully set the display to 3440x1440 100hz.

     

    Now I know OD has nothing to do with refresh rates Smiley Happy

    MatuX - glad you found the monitor overclock function in the OSD.  Yes this is indeed what you have to enable to get to 100hz.

     

    FYI - you want to leave the Overdrive on "normal" for best results.  See the tft central review here, specifically the "response time settings" section:  http://www.tftcentral.co.uk/reviews/acer_predator_x34.htm  (It gives good Grey-to-grey times and also minimal error % compared to Extreme setting.)

    Game of choice....   Son and I play lots of online/mutiplayer of Battlefield 4... amazingly realistic 'FPS' style game.
