So I want to connect my monitor to a controller and play fortnite and other games there. Do I need a desktop? If so, for what?
If you connect your controller to the monitor (which is not possible at first), you still need hardware on which the game runs, compare it to a car:
the controller is the steering wheel and the monitor is the road, only driving with a steering wheel is far from driving.
A monitor alone is not enough for you. Of course, you also need a device that calculates the game for you. E.g. A desktop PC, laptop, console
If so, for what?
What else should the game run on?
However, a laptop is also possible. However, since the price-management ratio is worse than that of the desktop, this is not an option. The laptop must also have a correspondingly small design, here the desktop has the advantage that it can simply be much larger.
If you connect your controller to the monitor (which is not possible at first)
oh, if your monitor has a USB port (e.g. If it has a HUB), you can already connect it to it.
It just won't do you any good if you don't forward it or the monitor is not an AiO PC
First of all you need a PC or a console.
You then connect this to a monitor.
Set everything up
You can start playing
Depending on how to understand, you can also "connect" your TV to your nose
By connecting is clearly meant to connect via a cable.
And monitors can have a hub built in, so you can connect the controller.
Yes, as some have already answered here, you need a computer, console etc. If you do not have a lot of money available and would just like to play on the system anyway, a console is recommended for price-performance reasons.
