How to: Force Warcraft 3 to display a high or widescreen resolution.

3/13/2011 Update: This registry edit is no longer needed as the new patch, V1.25, adds widescreen resolutions to the video options in the game.

Warcraft 3 by todays standards is an old game, but it is still popular. Larger monitors, 21" or larger, have native resolutions that are not supported by Warcraft 3. There is, of course, a way to force Warcraft 3 (both Reign of Chaos and The Frozen Throne) to run in a high or widescreen resolution. The only way to do this is to do a simple registry edit. I have included a couple of pictures to demonstrate how to do this registry edit. I have done this before in the past and it is safe.

First, we need to open a 'run' window. Go to Start--->Run--->RegEdit. Then follow the below navigation...

HKEY_CURRENT_USER\\Software\\Blizzard Entertainment\\Warcraft III\\Video

There are two variables that you must change: resheight and reswidth.

Make sure you change the default hex value to decimal value.

Example - 24" widescreen with 1920x1200 resolution.

reswidth = 1920
resheight = 1200

You may have to restart Warcraft 3 for the change to take effect. Thats all there is to it! Have fun playing Warcraft 3 with your monitor's native resolution.

I am glad to help out!

Do you play public or private/league DotA? That is the primary map that I play, I usually play at least 2 TDA games a night. Maybe we could get a game going and I could show you a few things.

If any of you are interested, I play on the Azeroth (USEast server) in the channel Clan RooF. Feel free to stop by and make yourselves at home.

Cool, my primary account is l)eathMasta (thats a lower case L) but I have a few other aliases that I play DotA on.

Yeah I know, but mind you I said 'by today's standards.'
