In game Resolutions

D2DX contains a mod that enables (for 1.09d, 1.13c, 1.13d and 1.14d) custom in-game resolutions, beyond the 640x480 and 800x600 of the original game.

It will, by default, select an adapted resolution to achieve integer scaling for the sharpest visuals. This decision can be overridden by the user via the configuration file, if desired.

Default resolutions

The table below shows the default in-game resolutions that D2DX will use.

When choosing these resolutions, care was taken for them to:

• Remain close to the default resolutions, without dipping below 480 in height.
• Not over-extend horizontally on >16:9 monitors (the game just isn't built for it).

I've tried to support all the common monitor resolutions. If yours is missing, or if you disagree with the in-game resolution choices - create an issue and let me know!

User-specified resolution

You can set a custom resolution by editing the "size" option under the "[game]" section in the https://github.com/bolrog/d2dx/wiki/ConfigurationFile. The maximum allowed size is your desktop size.

It's not recommend to exceed ~720p (1280x720), as the game isn't built for high resolutions and may exhibit issues/bugs.
