Hi,
I have recently changed my graphic card and I can't manage to get a 1920x1080 resolution on Archlinux.
I have a dual-boot and it works flawlessly under on Windows.
There are some special points, though.
- I have a VGA-only monitor and my card has 2 HDMI, one DVI-I and one DVI-D so I have to use a DVI-I to VGA adapter.
- When I first booted up on Windows with drivers properly installed, Windows considered that there was an other HDMI display althought there was'nt. As a result, there was an extended desktop. I managed to "take back" the settings windows on my monitor and disabled the HDMI display, making my monitor as a primary monitor. Since then, it works perfectly. Under Linux I had to disable one HDMI output to avoid extended desktop too.
- I suspect that there is a problem with my monitor's EDID, probably because of the adapter which prevent drivers to properly get EDID.
- I tried to save the EDID using a tool on Windows and then use it as a custom edid on Arch but when i parse the edid there is an error.
- I also tried to force the 1920x1080 resolution using xandr, but even if I can create a mode, I can't add it to my output cause I have an error message. This happens because as soon as I create a new mode using the --newmode switch, this mode is diretcly associated to the DVI-D output.
- I think my card has something special because it can take HDMI input to improve rendering of some HDMI peripheral and then give the result as output.
My card is a kfa2 geforce 750 TI Darbee Edition.
I have spent hours on this problem and I ran out of ideas now.
Hope someone can help me.

So sorry to answer my own thread, but I managed it to work.
I used an other computer to get the EDID of my monitor. I saved it and copied it on my arch computer. I then followed the wiki to add it to the kernel command line.
I had already did it, but I made a mistake, since I hadn't deleted nvidia proprietary driver.
Right now I am trying to get full resolution during boot since I have a splash screen.
