Basic Question

I just wanted to know something about OpenGL… can you use it at all screen res’s and all differnt color depths? Or is it like Direct3D and only works on some screen resoultions and only on some color depths?

Yes, you can use OpenGL at any resolution that your OS supports. Obviously, you couldn’t have a screen resolution of 700x250 or a bitdepth of 19, but if you can tell your OS to use that resolution, then it can be done.

Two caveats.

One, OpenGL does not provide a facility to actually change the resolution. You will have to use the Operating System tools to do that.

Two, OpenGL may not use hardware acceleration at all resolutions and bitdepths. You will have to find out for yourself which resolutions and bitdepths your card supports.
