Peut-on brancher deux ordinateurs sur le même écran ?

Oui, sur des entrées différentes : USB-C, DisplayPort et HDMI sont indépendants. La source affichée se choisit depuis le menu de l'écran ou sa télécommande.

Le clavier et la souris suivent-ils automatiquement ?

Seulement si votre modèle intègre une fonction KVM ; vérifiez sa fiche technique, ce n'est pas systématique. Sinon, un clavier et une souris multipoints, ou un commutateur USB, règlent le problème.

Peut-on afficher les deux machines en même temps ?

Sur un même écran, l'affichage se fait source par source : vous voyez l'une ou l'autre. Pour travailler simultanément sur les deux, il faut deux écrans.

La luminosité change-t-elle quand je bascule ?

Non : elle appartient à l'écran, pas à l'ordinateur. Le protocole DDC/CI permet de l'ajuster depuis la machine active, quel que soit son système.

Quel modèle offre le plus d'entrées ?

Le P32T, avec deux HDMI 2.1, un DisplayPort 1.4 et un USB-C délivrant 100 W. Les G32P et G32X proposent également deux HDMI 2.1.

Two computers on a single monitor: how to do it

Two computers, one monitor

Work computer on one side, personal machine on the other: rather than stacking two monitors on the desk, you plug both into the same panel and switch between them. Here is how to go about it, and what to plan for the keyboard and mouse.

The setup Keyboard and mouse

Several inputs per monitor Switching by remote One desk, two machines

The principle

One machine per input

Kuycon monitors have several independent video inputs: USB-C, DisplayPort and HDMI depending on the model, some even with two HDMI 2.1 ports. Nothing stops you plugging a different machine into each and choosing the displayed source from the monitor's menu or its remote control.

The most comfortable setup:

The work laptop on USB-C. It receives the picture, the hub's peripherals and up to 100 W of charging over a single cable: you set it down, plug in, work.
The desktop on DisplayPort. It is the fastest route, the one that gives full resolution at the maximum refresh rate.
A console or a third machine on HDMI, if the model offers a second one.

Switching is done from the supplied remote control: no button to hunt for under the panel, no software to install.

The real issue: the keyboard and mouse

Switching the picture is trivial. Bringing the keyboard and mouse along is less so, and that is where most setups get stuck. Three solutions, in order of simplicity.

1. A multi-device keyboard and mouse

The most elegant solution, and the cheapest. Many recent wireless keyboards and mice remember two or three devices and switch at the press of a key. You change the monitor's source, you press the key on the keyboard, and everything follows. No extra cable, no compatibility to check.

2. A USB switch

A small box into which you plug the keyboard and mouse, connected to both computers. One button switches the peripherals from one machine to the other. It is reliable, universal, and works with wired hardware as well as with a wireless receiver.

3. The monitor's KVM function

Some monitors include a switch that automatically brings the hub's peripherals along when you change source. That is the most comfortable when the feature is present — check your model's spec sheet before counting on it, because it is not standard across the range. Without it, the two previous solutions solve the problem perfectly.

The setup we recommend: a multi-device keyboard and mouse, two video inputs, a remote control to switch. No accessory to buy, no compatibility limit, and it works whatever the operating systems of the two machines.

Two systems, one monitor: the settings

Each machine keeps its own display settings, and that is a good thing: macOS applies its Retina scaling, Windows applies its own. Two points to watch:

Brightness belongs to the monitor, not to the machine. It does not change when you switch. The DDC/CI protocol lets you control it from whichever computer is active.
The refresh rate is set per input. If your desktop is on DisplayPort and your laptop on USB-C, check the refresh rate on each side: Windows often defaults to 60 Hz.

Which models suit this best

The ones with the most inputs. The P32T lines up two HDMI 2.1, one DisplayPort 1.4 and one USB-C with 100 W: four possible sources. The G32P and G32X also have two HDMI 2.1 in addition to DisplayPort 2.1 and USB-C.

FAQ

Two machines on one monitor: frequently asked questions

Can you plug two computers into the same monitor?

Yes, into different inputs: USB-C, DisplayPort and HDMI are independent. The displayed source is chosen from the monitor's menu or its remote control, with no software and no special setting.

Do the keyboard and mouse follow automatically?

Only if your model includes a KVM function; check its spec sheet, it is not standard. Otherwise a multi-device keyboard and mouse that switch at the press of a key, or a USB switch, solve the problem very simply.

Can you display both machines at the same time?

On a single monitor, display happens source by source: you see one or the other. To work on both simultaneously you need two monitors, or a machine able to control the other remotely.

Does the brightness change when I switch?

No: it belongs to the monitor, not to the computer. It stays identical from one source to the other. The DDC/CI protocol lets you adjust it from whichever machine is active, whatever its system.

Which model offers the most inputs?

The P32T, with two HDMI 2.1, one DisplayPort 1.4 and one USB-C delivering 100 W. The G32P and G32X also offer two HDMI 2.1 in addition to DisplayPort 2.1 and USB-C.
