Yes I almost put a caveat in there but still most common stuff usually seems correct, I wouldn't dismiss everything on it otherwise what's the point of it?

EDIT: did a quick google and found this in PCmag.com encyclopedia, the last sentence is what I was reffering to:

Monitor Size and Resolution
The standard resolutions are 640x480, 800x600, 1024x768, 1280x1024 and 1600x1200, the latter three being the most commonly used. For example, 1024x768 means there are 1,024 columns and 768 rows of pixels on screen. The higher the resolution, the more material is viewable on screen; however, a high resolution on a small screen makes text very small.
