I bought Tales of Monkey Island on good faith and because I wanted to support what TellTale Games stands for. However, I cannot fathom why there still are problems getting your games to run on certain resolutions.
I have a Radeon X1600 Pro running on a Samsum 37" HDTV with a native resolution of 1370x768, and I cannot play this game in any widescreen resolution. Instead, I need to run the game stretched. Frankly, I have problems understanding why this isn't fixed yet. Wallace & Gromit worked for me!
EDIT: Alright, sorry for this post, but I found this fix right here. Still, this is kind of ridiculous.
