24" Monitor Instalation

I would appreciate some guidance to install a new monitor. I'm replacing an old 21" CRT with a new Acer 24" (AL2416W) wide screen .
I hooked it up with the DVI cable that was included and the resolution set at 1920/1200. It looks lousy and the horizontal to vertical proportion is out of skew and there is a constant rapid flicker.
There is a disk that came with it with some software included but no instruction of what to install.
Can anyone with similar experience give me some pointers on the quickest way to make this thing work properly?
Could this be a video card not up to par? The computer says I have a Nvidia FX500/FX600. Any help appreciated.

Regards,

A few things to try:

Set your refresh frequency to 60hz, your CRT was probably using 75-85hz.

Verify your video card can drive 1920x1200 with the DVI cable. You may need to stick with the standard VGA cable to achieve highest resolution setting with the lower end card you are running.

Unload your Nvidia drivers completely then download and install new version after restarting.

The monitor drivers can be installed by opening the systems device manager, right clicking on the generic monitor listed and select "update driver." A few prompts later it will ask for your CD.

  Anthony, Thanks for the info. I'm Pretty sure I have the latest driver. I reduced the resolution to 1600/1200 and the flickering went away but I can't find a way to fix the horizontal stretch in every thing I'm running. I'm making eggs out of golf balls and everyones picture on this forum got short and fat.
  I did install the software that came with the monitor. There are no Hor/Ver adjustments in the software and in the button menu on the monitor they are grayed out.
  This is a true Plug & Play the blues device.
  
  Regards,

    I opened the screen shot on my laptop when I got home tonight and low and behold I'm looking at a golf ball and not the egg I've been seeing all day. I imagine thats what anyone that opened it was seeing.
    At any rate I did manage to get the display to look as it should on my desktop by doing something with the Nview settings for the display. Somewhere around 780p setting 4 I'm not sure. I stopped when the circle was finally round.
    It's still acting funny at startup but I can live with it until I can get some tech support from China.
    I should have gone with the DELL instead of the ACER China still but better support.
    
    Regards,

      1600x1200 is a 4:3 aspect ratio resolution (i.e. old 'square' style monitors). Displaying that on a wide-screen causes the stretching you're seeing. Most wide-screen monitors display with a 16:10 aspect ratio, though i've seen some at 16:9. In your documentation, and possibly in the monitor OSD itself, you'll find the "native" resolution. Setting your resolution equal to the "native resolution" will give you the best possible picture quality.
      
      Are you using an adapter to convert from VGA to DVI? Using straight DVI, refresh rate should not be an issue, as it is always equivalent to 60Hz. Also, stretching and skewing should not be an issue either because the monitor interperets a digital signal and places every pixel with 100% accuracy. With a VGA->DVI conversion, incorrect detection of incoming horizontal and vertical scan frequencies can make the picture screwy as you describe.

        Joe, Thanks for the info. I ended up using the VGA cable and removing the DVI connection. The resolution is set at 1920x1200. I selected Auto Configure in the OSD and everything looks normal. My mouse pointer jumps around like a flea for about 30 sec. at startup but stabilizes when all startup programs are loaded.
        I am pretty happy with the way things look but I was disappointed with the fact that Tech Support from ACER never answered my email or called.
