How can I use very high resolutions like 2560x1440 in Terraria?

My monitor has a native resolution of 2560x1440, and I'd like to use the full resolution in Terraria. Unfortunately the game only allows resolutions up to 1920x1200 to be set from the video menu.

I assume the resolution is set somewhere in a config file, but the main Terraria config file seems to be binary, so I couldn't easily find the place where the resolution is stored.

Is there any way, official or not, to set the resolution to something higher than 1920x1200?

Solution 1:

The game has a maximum resolution of 1920 by 1200 hardcoded into the game executable. Some mods, such as this one, supposedly let you bypass this limit. (I could not test it as my screen resolutions don't go high enough.)

Solution 2:

Terraria is made in the XNA framework. It has been programmed to the various screen size in the menu, and these variables are called by the Console.Buffer. To answer your question, the only two ways of doing this is to either change the code so it sets the height, width and resolution to your desire (which is not possible since it isn't open source). Or edit the binary file.

However, it is important to note that, that Terraria 2 is promised to be fully customizable and will probably solve such problems.
