Clone desktop on multiple monitor with different resolutions

I have a HP 2510P laptop with me. It has Windows XP on it. Now I purchased a bigger monitor for getting common screen on multiple places. It is a 20" monitor. Now the existing one offers 1280x800 resolution maximum and the second monitor has maximum 1680x1050 resolution. I can get the screen working, but there is no exact resolution that I am looking for. I want to know that there is a way by which I can arrange different types of resolution on multiple screen at a single time.

No there is nothing you can do. This type of features are only found in graphics card but they are also very rare. You can have a common resolution in much easier way. Or you can simply use the second monitor as your default display device. Then it will be possible to get right drivers.
