Am just discovering the joys of ZunTzu but ... my laptop screen resolution is 1366 x 768 and when I run ZunTzu the display area isn't filling the screen - I'm getting black edges on both sides. I've tried using the obvious display settings in the program and also ticked the widescreen option with no success. I'm running Win 7 Home 64 bit.
Are you connecting to a game hosted by someone else? The hosting user actually controls whether you see Widescreen or not, your local setting won't matter in that case. If not, then that's a weird one. It works for me at 1920x1080.
Hi!
Look for the widescreen check box in the display settings.
It makes all players switch to widescreen. Players with 4:3 screens will see black bands on top and bottom of the screen.
