[PBS Question] Black zone on screen

[Sibeas]

I just downloaded a Essentials version with UPI an EBS installed and I played it in order to know if it was stable but when I opened it, a portion of the screen was black and the game screen was just a corner of the window, there's any way of fixing this?

In Scripts -> Settings

Check for something similar to this, I'm using an older version of essentials but it should be the same/very similar.

DEFAULTSCREENWIDTH  = 500
DEFAULTSCREENHEIGHT = 500
DEFAULTSCREENZOOM   = 1.0

Play with the values and see if it changes things for you.

Now the window is slightly bigger but the black zone stands still.
Plus now I can't post the image due to the 5 post restriction, lmao.
