The issue you are having is that you are comparing your glossy screen Samsung 206bw monitor to a matte screen monitor. Glossy screens over-saturates colors and gives them that shinny look; in other words colors are more vibrant. The Asus and most other monitors have matte screens rather than glossy.
The only two companies that I am aware of which makes glossy screens are Apple and HP. I don't like monitors with glossy screen personally. You need to be careful when searching for a glossy screen monitor though. Many times the word "Glossy" will appear in the description. But it does not refer to the screen itself; it is referring to the bezel (monitor casing). The LG M2762D-PM is such an example...

The LG's screen actually has a matte finish.
Actual glossy HP screens that I know of are:
