Cannot set benchmark resolution to screen resolution

[Mikey2]

Although I have multiple monitors, I want to run the benchmark on my main monitor...it is a 20" Samsung monitor with the standard resolution of 1680x1050. (Windows 7 labels it "recommended" since that is the highest possible resolution on this monitor.)

However, when configuring my benchmark [PCMark Vantage Advanced x64 version 1.0.2.0] resolution the only options are 1024x768 [the default], 640x480, and 1280x960.

Which resolution should I use? Or am I missing the option for my "real" resolution because of a problem with my PCMark installation or something. In addition, I've been using the default 1024x768, but I did some extensive searching on this board and it has been suggested to use the higher resolution setting. However, all of the select-able resolutions are in a 4:3 aspect ration, where my monitor has a 16:9 aspect ratio.

Is there a problem with my system where the correct resolution is not being offered by PCMark, am I supposed to use the default 1024x768 default, or should I set it to 1280x960 since it is closer to my monitor's resolution?

I have a pair of NVidia 8600GT GPU's in SLI mode (and normally in multi-screen modes) if it helps.

Thanks much in advance for your help!

Those resolution options affect only the 3D tests and even they run always run in a window. It really isn't designed to be a graphics benchmark - it is more of an overall system performance tester using various Windows tasks and components.

If you seek to test the 3D performance and want 3D performance measurement in full screen, may I suggest 3DMark Vantage or 3DMark 11 instead?
