In Tales of Monkey Island, when selecting a resolution of 1280 wide by 720, 800 or 960 high, the game still displays at 1280 x 1024 (reported by my display). As a result, it takes the form of a 4:3 letterbox image.
On a wide display, this means a large black border on all sides.
All other resolutions seem to work as expected. I do have the latest Catalyst drivers for my HD 4850.
Anyone else have this problem?
