Does Windows 7 have an option to enlarge everything on the screen, e.g. via a spi setting? How well does this work? i.e. do the objects look clear when enlarged?

I ask this because sometimes software that enlarges non-photographic bitmap images e.g. icons and symbols can leave them artifacted with harsh jaggier slopes and blurred lines.

I've tried the dpi setting in Windows XP but it doesn't enlarge everything, and some things are not so clear as described above.

I'm looking at a notebook/laptop with this spec. I've already enjoyed using a 15.4" 1920x1200 display for 5 years.

I am buying a laptop for my father who will probably prefer larger objects on the screen, although I want to provide some future proofing by allowing more on the screen if needed.

I'm not interested in answers that debate the effectiveness or otherwise merits of 1920x1080 on a 16" display, please. The alternative option of 1366x768 seems too little.
