Can't find Fullscreen mode

[AcId]

AHIII fresh install.
Desktop resolution 3840x2160
55' Samsung S90F
4080 super

Game launches in windowed mode and even with the resolution set at 3840x2160, the window is not fullscreen and seeming less than the advertised res setting.
I can't seem to find how to get the game in fullscreen mode.
I've gone through the settings I know of to no avail.

I'm guessing this has been addressed before but my attempts at bb search turned up nothing.

Thanks.

I have no idea what I did, but it's good now lol

Thank you sir! It's been a long time. Next step is to see if I can get my old handle back or not. That used to be an email to Pyro.

Hitech is the only employee these days. Give him a call and he'll sort you right out.

If that's the case I shouldn't bother him. I can come up with another

The game starts in minimized screen setting.. one you click to enter an arena it should go to full screen mode.

Not sure if that is the case for you

To be honest, that was probably my problem and I didn't notice.

Roger that.. thought possibly you didn't attempt to log into offline or any arena and didn't realize it would expand once the arena starts to load

Welcome back.. I hope that is the extent of your issues.
