Just managed to get a hand on a beta key, but when I finished downloading the game and launched it, the monitor turns black and I get an error message saying "Input not supported". In other words, I can't see sh*t.

Having played League of Legends before, I remember this problem when I first installed that game too. The way I solved it back then was going into the game folder and change the .cfg file to set the standard resolution to that of my own monitor.

I did manage to find the .cfg file in the dota2 folder, but I can't seem to find any lines about resolution in any of the .cfg files in there. There's probably an option in-game to change the resolution, however, since my screen is totally black I cannot navigate whatsoever after launching the game.

Does anyone know if there's a possibility of just typing in a line like UserSetResolution=1 and then Resolution=1440x900? Or is there some other way around this problem?

Would make my day if someone could help me with this problem since I've really been looking forward to playing this game!

EDIT: It seems I got 2 invites along with the beta key, so if someone comes up with a solution and hasn't got access to the beta yet I can help you out
EDIT2: The issue has been solved. Thanks a lot to Apwny and his friend!

wait for the tech maniacs or those ones who have a beta key, patience.

Check your PM, i could help you

Ok topic solved, i close it!

Don't pm each other. If others encounter same problem, they should also see solution. Post the asnwer.

The Solution is:

simple step:


go to Steam -> Library -> Right click on DotA 2 (or any other Game on Steam, which is a Steam game / Steam supported game ) -> Set Launch Options -> write following:

-w 1440 -h 900

this means, the game will start always in that Resolution 1440x900
