One issue is making it look natural, although some people like more unnatural looks, that's for the photographer and audience to debate (personally I'm not a fan of overblown HDR effects except in rare subjects). It must map that range onto the 8 or 10 bits of brightness your monitor supports (or whatever your printer allows, etc.), but you still see a lot more Dynamic Range from the original scene. The HDR software then chooses to use the bright detail from the first image and the dark detail from another. However by taking 3 (say) 14 stop images separated by 3 stops you get information for 20 stops of brightness (so for the Sunny Window in the dark room you have a shot showing what is outside, but that shot won't show what's inside, it will be mostly black but you have another shot with the interior detail and the window is white). You can have 20 stops of brightness in a scene, so whatever exposure you choose a lot of the detail won't appear (you should get everything on a dull day with 8 stops of DR in the scene though). What the camera's exposure system allows is for you (or it) to choose what brightness level that range is arranged about. Cameras can only capture 12-14 stops of brightness (outside that range you get white at the top end and black at the bottom). "High Dynamic Range" is referring to enabling you to see more of the brightness range in the original scene.
