Laptop Screen Resizing Question

My first laptop, an Dell Inspiron 8000, could resize the screen using FN+F7, which put black borders around programs running beneath the default laptop res. Call me odd but I actually preferred running low res games like Starcraft in the smaller but crisper looking window, despite the tininess of the sprites. I`ve since moved onto a Compaq laptop, which doesnt have a simliar FN+F7 function, but in 2007 I am looking to buy a new Dell laptop hoping to regain this function. I`m wondering if anyone knows of any current Dell laptop models which still feature this screen resizing function -- I`d like to be able to put certain current PC games [which honestly arent smooth running at high resolutions, on a laptop at least] in a similar bordered window in order for them to appear sharper looking. Anyone know of current laptops that have a feature similar to FN+F7 on the older Dell laptops? Thanks in advance and happy holidays to all.
