Incorrect screen resolution with NVIDIA drivers

Bug Description

My Samsung screen resolution is 1920x1080. Ubuntu 12.10 under system settings displays it only allows four options 1360x768 being the highest. My video card is a G84(GeForce8600GT). There are 4 additional drivers available the all work but don't change the resolution. The nouveau driver caused the screen to flicker evert few seconds.

I also looked in NVIDEA X Server settings but again the highest resolution is 1360x768 (it says NVIDEA Driver version: 304.4).
I'm not sure which is leading - System settings/Display or NVIDEA X Server settings.

Because the card doesn't have a VGA port and the screen interface is VGA I have to use an adaptor to convert from DVI to VGA

Its a real shame because I have gone for it and wiped out Windows! Hooray!

Any clues welcome!

Do you see text " This bug affects 1 person. Does this bug affect you?" right above the "Affects-Status..." table? Push the "Edit" button (with a pensil picture) and choose "Yes, it affects me".

same issue: max size for me is 1280x1024 "Laptop". Interestingly, the first time I booted 12.10 the screen was fine, but every subsequent time it's been punched in.

Same issue also: maximum resolution available is 1024x768 and should get 1080. Graphics card is a NVIDIA GT520. I have tried all version of the driver offered in "software sources" with the same results. The default nouveau drivers works at the expected 1080 resolution as do the NVIDIA drivers on 12.04 Precise Pangolin.

I have decided to workaround the problem. I installed my old ATI Radeon card from my old (dead) PC. Then I installed the Zorin 6.1 distribution. I now have the correct screen resolution and full control of the screen i.e. in "Displays" you can see the make & manufacturer of the screen and is switches off when Zorin shuts down.

I am convinced that a major part of my problem was that my nVidia card does not have a VGA interface and my screen only accepted a VGA interface therefore I had to by a DVI to VGA converter plug. It may be that this blocks the ability to control the screen ( Only a guess). Zorin 6.1 is based on 12.04 which also seems to resolve the driver issues.

I will stick with Zorin from now on.

I hope you get to the bottom of the issues in 12.10. Thanks for the help so far.

@MikeyP I think the fact you're changing to ATI from nVidia is solving your problem, the DVI/VGA difficulties are just a red herring, because graphics cards simply transmit the VGA over these DVI adaptors.
