I have an EVGA GeForce GTX 550ti graphics card.  I purchased a new 1920x1200 monitor, but cannot get it to work higher than 1920x1080 with this graphics card, the monitor just gives me an "out of range" message instead of a picture (the 2nd monitor at 1600x1200 works fine at the same time).  Am I just doing something wrong, or is this a limitation of the graphics card?
 
Previously the system ran with two monitors at 1600x1200, one of them has been replaced with the new 1920x1200 monitor.
The GTX 550Ti has a max resolution of 2560x1600 (=4,096,000).  At first I thought I this value was the sum of both DVI ports, but have since read conflicting posts and don't know if that's true, and in any case even if I disable the 2nd monitor I still can't seem to get this up to full resolution even as a single monitor.  The new monitor works fine at 1920x1200 as a single monitor on a different system.  If it matters in any way, I'm actually running through a DSUB cable with an adapter into the DVI port in all these cases.
 
Thanks for your time!

    Dsub doesn't support the full resolution of 2560x1600 as dsub is analog. that said analog supports 2048x1536 and 1920x1200 is under that. Let me look up the specs again...
     
    hmm, I would think it should work, but it'd be best to not use Dsub if at all possible, try DVI, pretty much any monitor that's made in the last... 10 years? should be able to work with that, or HDMI, if your monitor has an HDMI connection you can try that as well (while full HD is 1920x1080 it seems that HDMI can go slightly higher than that, at least I've been able to do it at 1920x1200)

      Ok, thanks for the help everybody!  When I went to try swapping from the old Dsub cable to the DVI cable, I figured out that for whatever reason, the problem was caused by the Dsub extension cable I hadn't even been thinking about (which incidentally had pin 12 removed to disable the monitor auto-detect). 
      (The removed pin was a workaround for the Windows 7 issue where if the 2nd monitor is off when the system starts up, the screen resolution is changed from whatever it is set to to the recommended resolution and all desktop icons are moved to the left.  However it appears that is no longer an issue, perhaps because this monitor IS running at the recommended resolution unlike the monitor it replaced, or perhaps things have just changed; in either case, that extension cable isn't needed as a fix at the moment.)
      I'm up and running!
