How do i resize my windows?

[Naijiro]

I got a 1440p monitor, and a 1080p monitor, accidentally dragged my screen to the 1080 monitor while the window was open in 1440p i can change the setting but i can't scroll all the way down to the button to apply it. Any tips?

You can try the steam launch commands, not sure if this will work with Larian's launcher though. Go to Library -> right click on the game -> Properties -> Set Launch Options. Not all commands work for all games for me, but you can try a couple like:

-windowed
-fullscreen
-w <width>
-h <height>

Alternatively alt+enter should switch between fullscreen and windowed mode. Actually try this one first.

I know this is an old question but just in case someone else had this problem.
I don't think the suggestion above works because of the Launcher, usually a Launcher would allow you to change this with the Launcher, but, Larians launcher is pretty useless right now. However, I WAS able to change my window size using GeForce, which is the software for my Nvidia graphics card. Whatever Graphics card you have, probably has its own software, that you can try to change the settings with that program.

When I started up baldurs gate after a graphic driver update, it was all jacked up. I couldn't click anything because it was all off the screen, so I had to use the GeForce program to change to Full Screen. IF this hadn't worked, and the launch command didnt work on steam, the 3rd option would be to search for the .ini file and change it there, and if THAT didnt work you'd have to figure out how to edit your .exe and manually put the launch parameter in.

Don't do any of those last 2 things without knowing what you're doing.

I was having a similar problem and changed the game to Dx 11, that fixed my problem
