True HD images should be 1920x1080 in 16:9 format ratio. Most movies normally presented in 2.35/2.40:1 format (sometimes in 1.85:1) of widescreen. It will be displayed perfectly in any monitor/tv with 16:9 screen ratio with very small area of black bar on top and bottom of the screen (it won't being seen if movie with 1.85:1 format). That is why 16:9 become a standard in home entertainment/monitor macnufacturer. Monitor with resolution of 1920x1200 is capable display full HD content due to it has extra vertical pixel of 1200 where full HD only need 1080. This resolution make this type of monitor a 16:10 display with capability of displaying true HD content in 1080p. The only thing you need to remember is there will be more black bar on the screen due to it extra vertical resolution...(1200 vs 1080).
