4k resolution on PC

[DonCalogero 0]

Goodmorning,
I bought Micromachines WS about 2 days ago and I have a problem on 4k resolution on PC. I can't set the 3820x2560, the max resolution that I can set is 2560x1440. If  I select the 3820x2560 and I apply, the game will sets on 2560x1440 all the times. I have 4k monitor and the right GPU. I tried to force it with Nvidia Control Panel, but doesn't work.
I need help to fix this.

Thank you,
DonCalogero.

It's a Unity game. Unity limits you to your desktop resolution. Is your desktop at 4K?
