Starcraft2 on widescreen TV

[avance70]

i have a widescreen TV (16:9) with resolution 1024x768
most of the games that i played have option to set the resolution different from the aspect ratio
for example WoW, CoD, etc. i would set the game resolution to 1024x768 and the aspect ratio to 16:9 and the games would look perfect!

now, i don't see a similar option for sc2 (i can, for example, play on 1280x720, 1600x900, 1920x1080, etc. but all those are interpolated, and not nearly as sharp as 1024x768)

i was wondering is there a way to do this for sc2? some settings thing or patch?
