I don't believe computer monitors really can support real HD at all. As far as I know, the standard computer monitors isn't even in the right size to support any kind of HD. It's only a marketing trick.

There are a lot of game that uses these higher resolution. Most games check resolutions supported by your monitor during startup. Then, the bigger monitor you've got, the more resolution to choose from.
