How do I recognize the descriptions of a glossy display of a laptop?

I would like to buy a new laptop and would like a glossy display. Maybe you can tell me what to look for and how to tell if the display is dull or shiny?

You realize that there's not "dull".

Glossy, glare-type, reflective = glossy.

Matt = matt

You can't buy a MATT otherwise you do not have your beautiful glossy display. ^^

so beware that you do not buy with MATT
