Hi there, Im useing a spyder 4 pro with software version 4.5.4 on windows vista 64. I have a few questions! :)
My two monitors are an LG Flatron E2240S and an LG IPS224

Since adding a new display my profiles are switched the wrong way round. When I goto calibrate my old screen the application switches to the new monitor. Is there some way I can totally reset the application?

Yes, there are files that could be removed that might allow the software to get "unconfused" about these two similar displays. Resetting prefs at app startup (I assume there is a keyboard command of that under Windows, I'd start by holding down the space bar and see if that does it) would be the first thing to try. After that, it would require removing specific files: for that info a support ticket at datacolor.com would be the best assistance.

Also, Im unsure how to find the exact type of my monitor back-light for both of my monitors. Is there some resource I could look at online to discover this?

Manufacturers are notorious for not listing the actual data for displays. It becomes a game of cat and mouse. If their newer displays say "LED backlight" but don't brag about the much more costly RGB LED backlight, then it means they are white LED (which is actually an edge light, not a backlight, but that doesn't matter here). If some displays state they are LED, then any that don't are still CCFL (Fluorescent tube) backlight. Gamut is less tricky. If it is close to sRGB, its standard gamut, if its closer to AdobeRGB, its wide gamut. Since running our software once will create a gamut graph, you can figure this out, then go to the ShortCut menu in the lower left, take the shortcut to display setup, and change the gamut (and backlight type) as desired. There is also a new type of wide gamut LED display showing up, which as green and blue backlights, and a red "filter"… we're looking into that one and should have a display type to match it in the near future.

The LG Flatron E2240S is listed as LED LCD. Process of marketing elimination means this is standard gamut, white LED backlight.

When calibrating the displays the wizard asks If my pannels have sections for WB kelvin presets. The E2240S has this with a selector for different temps. However, the IPS224 has a section that obviously lets you manipulate the temps via three sliders, but they are not labeled with presets. Im unsure whether I should choose yes or no for this one.

In any case, choose the preset or setting that is closest to your target white point. 6500k, D65, or some such. This is just to get you as close as possible before the software takes over and adjusts this in the video LUTs.

Last question, Im unable to get either of the LG inf files installed on vista 64 for either monitor, will this effect me in anyway?

Thats a matter between Windows, the display drivers, and the .inf files; which may offer extended resolutions, refresh rates, etc, above the standard plug-and-play settings. Figure out what resolution and refresh you want, get it configured how ever you choose (third party utilities are sometimes used) and then calibrate the displays AFTER you have finalized these settings, so that you are calibrating the correct video stream. And be sure you don't go for some unreasonably high resolution and refresh rate which can only be reached by reducing the color depth of your display; you need at least 8 bit per channel color to do quality image editing.
