I don't use anything. The Nvidia control panel handles it just fine. You can select resolutions for each monitor independently.

I have a 22" LCD monitor and a 37" LCD TV hooked up.  I just use the Windows Display Properites and the Settings Tab.  You will have to try a few resolutions and find on that works on both monitors.  Yours are close in size to one another so it should not be to hard.  Your Video card should also have some software to help set up the monitors.

You can use 3rd party software but why bother.

Windows (at least XP and later) handle dual monitors easily.  You can set each resolution independently in the Display Properties area.

I use UM with WB and have no issues.

Wow, less than an hour and four responses.  Thanks guys I'll give it a whirl.  Monitor should be here today or tomorrow.

No separate software - not even NVidia one...

OS X handles everything seamlessly

As noted, XP handles it fine. I have a 19" regular and a 22" widescreen and have them both at their native resolutions with no issues.

That being said, I use DisplayFusion so I can have separate wallpapers on each one.

Or just put them both on one big image and set it to tiled, no extra software needed.

I am running dual 22" widescreens on XP with a Nvidia GeForce graphics card.  I have two programs that I like. 

    DisplayFusion - good for wallpaper settings and also a few very useful hotkeys

    Deskangel - ability to have scroll wheel on mouse work on the window under the cursor (whether it is active or not)

            (This is the most useful of the 2)

I think there are other programs that do the scroll thing, but I use Deskangel.  I don't use it for any of its other features though.

John's Background Switcher...it's free and it's the best wallpaper handler for dual+ monitors.  I replaced DisplayFusion and Ultramon as wallpaper handlers with this wonderful program.

Ultramon - if you want a separate taskbar per monitor with only the programs running on each monitor displayed there.  It's cute, but I never found it all that useful.  I have one central/vertical taskbar replacement (ObjectDock zoomer) and that's the fastest, least mouse traveling road for me.

Otherwise, Vista and Window 7 handles multiple monitors just fine.  I have 3/4 depending on home/work.

XP has problems with hardware GPU acceleration on the non-primary monitor, so you'll want to keep an eye out for that.

Irrelevant.  The poster clearly uses an edition of Windows.

Yeah, I use just plain windows. 

In the past I've used Nvidea's or ATI's software that came with the cards in use.   (and before that I used something that came with my 3Dfx voodoo cards, I don't remember what it was called)

I've never really used any 3rd party software (except maybe in the case of the voodoo cards, but I know I did get it off a disc that came with them, so it was psudo 1st party at least)

@Excalpius - do you have a link for your switcher app? I'm always willing to try new things.

Spartan, you can find it here: http://www.johnsadventures.com/software/backgroundswitcher/

*edit* Kryo: yea, but DisplayFusion allows me to cycle the wallpapers at intervals of my choosing. No extra work required.

Thanks I'll give it a shot. karma given! 

Thanks, I just assumed you'd Google the program name.  It comes up as the first link.  Enjoy!

Within Vista_HP (6001.vistasp1_gdr.080917-1612) own flawless gimmick of 1 or 2.

While sometimes going for a swift pre-configured N-Vidia setup, as long as i can remember to switch the second monitor ON; black screen may just seem empty or off.

Rarely.

I use Ultramon64 and like it. Have had no issues with it and Vista or WB.

While most people here still seem to be using XP, I'll add that Vista and Windows 7 also handle dual monitors without any additional software.

In addition, nVidia's software (and I'm sure ATI's as well) also supports dual monitors. I don't use any other third party software.

I use UM for the taskbar and wallpaper management. Vista does indeed handle it fine as does the Nvidia control panel but UM offers a few extra features that i really like, and it's in no way a resource hog.
