Question about a switch

[Sylver]

It is exactly what kynes says, there is also no way to express it more clearly.

You connect the switch to both computers, but on your brother's graphics card you must connect the switch's VGA and another video output for your brother's monitor (whichever one, just make sure to set it to clone mode as kynes says) and that same computer of your brother should have connected its own keyboard and mouse, either via USB or PS2, which as kynes explains to you, will not interfere at any time with yours USB connected to the switch, at least as long as they are not used by anyone at the same time. In this way, you have your keyboard and mouse both USB connected to the switch, and they control your computer when you have it selected, and your brother's when you select it, without needing to touch his keyboard and mouse, or the monitor, none of which three will need to be disconnected from his computer, and you will control it entirely from your keyboard, your mouse and your monitor, exactly what you wanted.

It is simply that, it does not have much science. Maybe a very detailed drawing would make you see it all at once, but I do not feel skilled to elaborate it, sorry xD
I trust that between kynes and I we have clarified a little more with these last explanations.

@kynes:

Let me try to explain it with another diagram:

This is the normal wiring diagram of a KVM. In this case, with the keyboard, mouse and monitor shown, which would be the ones you use, you control computer 1 or 2 depending on the button you press on the KVM. The KVM connects to each of the two PCs, in this specific case, with a cable that includes VGA connection to the graphics card, and a USB port that carries the keyboard and mouse signal.

You could have an extra monitor, keyboard and mouse connected to computer 2, which would be your brother's. You would have to configure the two video outputs in cloning mode on the graphics card, to show the same thing through both monitors when you select your brother's computer on the KVM. There would be no problem in having both keyboards and both mice connected at the same time, the only thing you couldn't do is block the one connected directly to computer 2, but it wouldn't cause any problem if your brother wasn't pressing keys, or moving the mouse.

Honestly, I don't know how to explain it better.

in short, does it need a monitor with dual input yes or not?

@CNCBCN:

No

[CNCBCN]

@kynes:

No

I think I didn't explain myself. We have computer A, which is yours, and computer B, which is your brother's. And monitor A1, which we connect to the switch. We also have keyboard and mouse A1, which we connect to the switch as well. With this, we can control both computers, but always with the same keyboard and mouse, and from the same monitor (this is where I realize I messed up :mudo:, but I'll continue in case I clarify something . Apart from that, we'll need a keyboard and mouse B2 for when your brother wants to use his PC B. These will be connected directly to his PC via USB, and a monitor that will also be connected to his computer (which would have to have a graphics card with dual output or an output duplicator (one of the outputs is connected to the switch, and the other has to be connected to his monitor)). Obviously, it can also be done with a monitor with dual output, but...

[kynes]

As you rightly say, you could do it with a monitor with dual output, but why? That's what a KVM is for. KVM stands for Keyboard Video Mouse, Keyboard Video Mouse.

@CNCBCN:

No dual input monitor at all… You need two VGA outputs from the graphics (duplicator) or one VGA and another one (DVI, HDMI...) for your brother's monitor, you have to have at least one VGA for the KVM switch.

If you mean with your comment that a single monitor can receive the two alternative signals from one or the other computer, that is exactly what the KVM switch is for, it is more than clear.

@Sylver:

Nothing with dual input monitor… It needs two graphics VGA outputs (duplicator) or one VGA and another one (DVI, HDMI...) for your brother's monitor, a VGA at least has to have it anyway for the KVM switch.

If you mean with your comment that a single monitor can receive the two alternative signals from one or the other computer, that is exactly what the KVM switch is responsible for, it is already more than clear.

It doesn't have to, there are DVI KVMs. They are more expensive, but they do exist.

@kynes:

No tiene por qué, hay KVM DVI. Son más caros, pero haberlos, haylos.

Sabía que me estaba precipitando, y es verdad, los vi hace unos meses cuando estuve buscando el mío leñe…

Culpa mía kynes.

Rectifico: NECESITA UN PAR DE ENTRADAS CUALESQUIERA QUE SEAN EN LA GRÁFICA DE SU HERMANO PARA CONECTAR POR UN LADO EL MONITOR CORRESPONDIENTE A ESE EQUIPO Y POR OTRO EL SWITCH KVM. (Normalmente traerá un par de ellas de cualquier tipo, con lo que no será problema a priori)
Solo tiene que conectar SU TECLADO Y RATÓN USB AL SWITCH, y en el equipo de su hermano puede tener conectados su teclado y ratón independientes del switch KVM ya sea por USB o PS2, que mientras no se toquen no interferirán en el uso que él le de desde el switch KVM.

Estareis hartos de oir lo mismo, vamos a quemar este tema una barbaridad, pero esto lo pongo a modo de resumen para que nos aclaremos del todo caray )
Lamento las mayúsculas.

No si me precipitaba hablando del switch, no del monitor xD
Las entradas que tenga el monitor de su hermano le vienen a dar igual, lo soluciona fácil con un adaptador :sisi:
