Can I connect a mouse and keyboard to the xbox one, and then play bo4 and fortnite?
Yes that works but it does not feel like it's on the PC, it has a small but noticeable delay as consoles are designed for controllers.
The expensive XIM Apex adapter could help to ignore this delay.
This is not possible without the adapter. Would be something completely new. Without the adapter there's nothing.
Of course, this is easy to connect to the USB ports of the console. As I said it is then something.
So fortnite goes then you can just connect the keyboard and mouse to the console,
Black ops 4 has disabled this feature so unfortunately that does not work. You can then use the keyboard only to navigate but not to gamble…
That's alright with the xim Apex
