Full HD means 1080p and it's a widescreen 16:9 display
1920x1200 is not Full HD.. it's capable but is it doesn't meet the widescreen standard.. it's 16:10
i would avoid a screen like that (although i have one but i would not buy again) for gaming because i don't like to have borders on top and bottom while playing a 1080p game... stick with 1920x1080 dipsplays
btw my LG monitor has a HD ready sticker although its 1920x1200.. even if a monitor has a higher resolution it cant be called full hd..
