Distinguish between panning and normal screen modes in code - Windows

Question

I am writing a full-screen 3D game and I have created a menu in which the user may select the screen resolution to match his hardware capacity.

I am enumerating all the available screen modes with EnumDisplaySettingsExA like this:

std::vector<DEVMODEA> modes;
DEVMODEA modeInfo;
int modeNum = -1;
while (EnumDisplaySettingsExA(0, ++modeNum, &modeInfo, 0)) {
    if (modeInfo.dmBitsPerPel < 16) continue;
    modes.push_back( modeInfo );
}

The problem is, I am getting panning-modes as well! I can't distinguish which are which; for example my ATI laptop has a maximum normal mode of 1280x800, but also contains a panning-mode of 1024x600!

Anyone knows of a way to distinguish between the 2, so I can reject panning-modes from my menu?

@Martin: I'm guessing the OP just put the res's in the wrong order.

It looks like it's the proper way to get the pixel dimensions of a screen in Windows.
