I recently purchased the viewsonic vx2255wmb (22" widescreen) and when I tried to connect via DVI to the Quatro NVS video card, the nvidia utility says my resolution is 1600x1200 and not 1680x1050. I tried to modify the xorg.conf and nothing has worked. However, if I connect via VGA connection, then everything works as expected.

Can someone help me with this issue?

Please see the forum sticky posts.

Thanks. I guess I'm confused. I looked at the stickeys and 3 of they are driver releases. I have the latest driver and looked at the release notes, but didn't find anything about my problem in the notes.

You need to generate an bug report that includes a verbose X log.

Ok, I read that, but didn't realize that's what you wanted :)

Ok, I ran the bug report and attach it.

Neither of the attached files contain a verbose X log.

Sorry, I'm a newbie at this. How do I start X with verbose 6? :(

Ok, let's try this again.

According to your X log, you need a pixelclock of 146.25Mhz for the 1680x1050 mode, but your NVS285 is only capable of 135Mhz:

(--) NVIDIA(0): ViewSonic VX2255wm-2 (DFP-0): 135.0 MHz maximum pixel clock
(--) NVIDIA(0): ViewSonic VX2255wm-2 (DFP-0): Internal Single Link TMDS
(--) NVIDIA(0): Detailed Timings:
(--) NVIDIA(0): 1680 x 1050 @ 60 Hz
(--) NVIDIA(0): Pixel Clock : 146.25 MHz
(--) NVIDIA(0): HRes, HSyncStart : 1680, 1784
(--) NVIDIA(0): HSyncEnd, HTotal : 1960, 2240
(--) NVIDIA(0): VRes, VSyncStart : 1050, 1053
(--) NVIDIA(0): VSyncEnd, VTotal : 1059, 1089
(--) NVIDIA(0): H/V Polarity : -/+

Hence, you're falling back to a 1600x1200 mode.
