Wide Monitor (3440x1440) - how to ?

Hi,
I am using Clover on a GA Z77X UD5H with a GTX770 4GB. Now I want to us my new 3440x1440 Monitor instead of dual screens.
Saw some threads - but did not find the ultimate information.
What is your experience ?
- nVidia drivers ?
- Graphics Enabler Yes/No ?
- Clover settings ? Driver ?

thanks

PS: Bios screen + Clover boot is OK; the Apple at boot is stretched; then screen is distorted

What is the connected cable you use? And what is smbios you inject?

iMac14,2 (no specialities (e.g. in Device)
Display Port - HDMI not positive as well.

Any idea ?

Does anyone having Yosemite running on a wide monitor with nVidia ?
What did you do ?

thanks

I'm using a LG 34UM95-PE without a problem. Only when booting, screen is stretched but on login screen, its oké.

Using Nvidia web drivers and HDMI (don't know if Display Port works for audio) but have no problem at all.

I am using a 34UM95 without issue. I am on yosemite and use an Nvidia GeForce GTX 970 SC, using the displayport. There is no audio over displayport, but I use external speakers anyways. I am booting with chimera, so I can't speak to clover, but it was as simple as connecting and powering it on to get it to work. I too have stretching during boot, but once the login screen shows up everything looks fantastic. I am on the 3,1 System Definition.

Got it!!!

Latest nVidia Web Drivers plus the attached Clover settings.

thanks & regards
