Warcraft 3 on a Widescreen monitor
If you own a Widescreen monitor, you are probably familiar with the black bars to the sides of the game field - not a pleasing sight. The good news is that you can do something about them, unfortunately Warcraft 3 don't support widescreen FOV's, but you can play War3 in Widescreen resolutions, read on...
Warcraft 3 custom resolutions
Custom resolutions in Warcraft 3 can be very useful if you have a Widescreen monitor or a TFT monitor whos native resolution isn't supported.
The native resolution on a TFT means the amount of pixels it has in the X- and Y-directions. CRT monitors aren't built up by a fixed amount of pixels and don't suffer from blurring when not running the resolution the monitor was manufactured for, like TFT monitors do.
Runnning Warcraft 3 in Widescreen
Warcraft 3 can be run in widescreen resolutions, but there is no setting for it in the game itself.
Here is a guide to setup War3 in Widescreen for Windows:
1) Make sure the resolution you want to run is supported by your graphics drivers.
If you can select a resolution in your Operating System, then it is supported. If the resolution doesn't exist, read our guide on how to configure custom resolutions in windows.
2) Backup your registry, in case something goes wrong.
START > Run > regedit > file > export
3) Change Warcraft 3's resolution manually.
START > run > regedit
While in the Windows Registry Editor (regedit), locate:
HKEY_CURRENT_USER > Software > Blizzard Entertainment > Warcraft III > Video
4) Make below change in decimal format:
(Right click > Change > select "decimal" > fill in new value)
resheight = 1600
reswidth = 900
Replace width & height with whatever resolution you wanna play in, examples:
852x480 16:9 Widescreen
1280x720 16:9 Widescreen
1365x768 16:9 Widescreen
1440x900 16:10 Widescreen
1680x1050 16:10 Widescreen
1920x1200 16:10 Widescreen
320x240 4:3 Aspect ratio
2048x1535 4:3 Aspect ratio
