Vista - Monitor Native Resolution Missing

I recently purchased a Samsung T220 monitor which is a 22" widescreen monitor with a native resolution of 1680x1050. I installed it on my computer with the latest greatest drivers. I however cannot set the native resolution to 1680x1050 as it is not an option of my listed resolutions. The highest resolution I can set it to is 1440x900. According to my Nvidia Control Panel my native is 1440x900. But this monitor for SURE is 1680x1050 native. I turn off the "hide modes monitor cannot display" but it only lets me show 1920x1080 NOT 1680x1050. Also in the Nvidia Control Panel I tried to use custom resolutions but it says not support by monitor. I know this monitor is capable of showing the resolution as I hooked it up to a XP machine and the resolution was able to be displayed. There is stuff out there with people having this problem but there appears to be no solution. I hear a lot of people on vista claiming it could be nvidia driver problem. I do have all the latest graphic card drivers and monitor drivers along with nvidia drivers.

Here is my computer specs:
Samsung T220 - Monitor
Vista x64 Ultimate - OS
EVGA 8800gt - video card
Asus P5N-D - motherboard
4 GB Corsair RAM
Intel Core 2 Duo 3.0 GHz 8400

Perhaps its time you called Samsung.

I noticed on their website the only driver available for that monitor is version "1.0" indicating no revisions. It was released in Feb of this year.

Could be a defect in the driver programming that some users experience on a given system configuarion (such as nVidia cards, or using Windows Vista, etc)

About that 1920x1080 option you mentioned, as it is the accepted HD Res, then did you try it, and if it worked, so how did it appear?

if you can use the 1920x1080 option i would just go with that gives you lots of desktop space and your card will run it fine you may want to lower the res for gaming but that is done in the game options anyway.

also keep an eye out for driver updates it may end up solving it's self with one of those.
hope you resolve the issue.

I can use it but my monitor says not optimum resolution. It is not support correctly by it. This is definately not a monitor issue, has to be nvidia problem and or vista problem.

its not a vista issue i have no problems selecting 1680x1050 on my 20'' samsung pebble

forget nvidia's control panel.... try & alter it through vista's display properties
control panel / display personalization / settings ..... here it should allow you to choose your native res.

Does not let me. The option for 1680x1050 is not there. Can't believe this is such a problem.

are there any options on your monitor that could solve this in it's menu? ie not in vista?

Nope.... I honestly am about to give up and just accept 1440x900.

have you tried previous driver versions? can you get another monitor to see if that works in the right res also i did have similar trouble on a previous computer running xp i just unplugged the monitor a few times and it seemed to work but i think it was a different problem you may just have to wait for a driver update to see if that solves it.

you could try to reinstall the display drivers, one of the control files may have been corrupt or encountered a system conflict, just a thought, i'm trying to think of anything that could solve this for you.

can you select that res in a game?
