KVM Switch HDMI USB 4 port, TreasLin 4x1 Quad Multi-viewer PC Selector,1080P@60Hz Seamless Switcher with Remote Control Support, RCA Output for PC Laptop

I wished to use this KVM as a KMmy setup is as follows:1. macos laptop on the LHS using its own screen2. windows desktop using 2 monitors on the RHSIssue 1The seamless mouse switching only works if the machines in your setup are each using only a single display since the seamless switching relies on detecting the screen boundaries which only works when each machine is only connected to one display (single 'head' configuration).This KVM is not unique in this respect as this is a limitation of most KVMs which allow such most based switching.Unfortunately there is no standard term for this feature with different manufacturers marketing this feature different. The terms I have come across include PASS (Progressive Auto switching), mouse gesture fast switch, mouse wandering, cross display switching to name a few.Issue 2:This is far more serious and potentially a deal breaker. when using this KVM with macos 10.13 or 10.11 the dragging operation simply does not work. I tried with the different brands of mouse to no avail and this was a deal breaker for me. What I do not know is whether this is a problem with the KVM or with macos. However, given that the mouse dragging (for example when selecting text) is such a basic operation, I find it curious that nobody else had noticed this issue.I shall be trying out a different KVM to check where the problem lies.SummaryIf you have a setup in which you have a single display connected to multiple machines OR each machine connected to its own SINGLE display then the seamless switching works flawlessly. However even then the drag functionality not working in macOS might warrant careful consideration and you would need to decide if it's a deal breaker ( I would have thought that it would be)

I have a standard usb mouse nothing fancy, and you loose precision when plugging it through this KVM. I have tried two other mouses and same result on two different PC's. You move the mouse a little bit, you get nothing on the screen. Move it further then it jumps. Very unusable. I have yet to test the other funtionality but this has annoyed me to the point where I just didnt try the other features. If I resolve this I will update my review.

Important to realize this is not a 4K switching device.Also, cable entry is both in front and rear.Creates desktop clutter...

Das Teil funktioniert zwar wenn man mal weiß wie, Die maus ist entweder in allen 4 bildschirmen gleichzeitig (einfach mit einer maus von bild zu bild spirngen geht nicht, es werden alle gleichzeitig identisch gesteuert -.-) will man nur einen pc steuern muss man als erstes in den channel wechseln auf vollbild und dann wieder ind die 4er ansicht.. die maus bleibt dann im letzten channel und kann verwendet werden, ein maus durchshcalten per knopfdruck wäre noch nett gewesen ohne das bild umschalten zu müssen... die fernbedienung braucht viele drücker bis mal was passeirt... im allgemeinen das gerät funktioniert aber die optimale wahl ist es wohl nicht... für mine zwecke reicht es aus...UPDATE: USB nach kurzer zeit DEFEKT!

Zunächst schwierig zu verstehen und anzuschließen. Die Anleitung ist auf Englisch und nicht gut zu verstehen. Wenn man ein Weilchen experimentiert hat und gerade alles wieder zurückschicken will, kapiert man doch, wie es geht. Bitte nur mit großem 4K-hochwertigen Bildschirm betreiben, da die Bildqualität und Auflösung bei günstigen reinen Gaming-Monitoren einfach nicht ausreicht. Was toll ist - die ultraschnelle Umschaltung der Maus zwischen den 4 Computern...faszinierend.

I've been using this KVM for several months now on a multi-monitor, multi-PC setup and there are some limitations.The main PC has two side monitors, plus the center monitor (connected to the KVM)Two laptops are also connected to the KVM.The KVM, I'm assuming, is doing some software imitation for the mouse, when I switch to my main PC which is three monitors, the mouse feels very strange and inaccurate, slight movements will quickly move it across all the screens.There is a MAJOR limitation for playing games such as First Person Shooters. If you hold right-click (to aim) and then left-click (Shoot) the KVM has a built-in hot-key to cycle the next display. There is also a problem with First-person shooters, is that there seems to be a software limit on the KVM mouse on the X and Y axes. Meaning, if I want to turn left, I move the mouse left, but it can only go so far and I cannot turn the character around after reaching the invisible limitation. I e-mailed the manufacturer and there is no way to overcome either of these two things. I overcome this by not using the connected KVM mouse when utilizing my main gaming PC (I have two mice on my desk), because overall when switching between my other work laptops, or not playing games, the KVM functions great for the price. The mouse has no problems are systems, that are using only a single screen.My only other gripe is that the KVM is capable of using audio from different systems, ONLY when it is in a multi-screen view. For example, I wish to be using PC 2 full screen, but listen to a conference call happening on PC 3 using the speakers connected to the KVM, I cannot do this. But I can do multi-screen view, with PC 2 side-by-side view of PC3, and have the audio from system 3. The device seems capable of doing what I want, but it seems it's not a feature.

Para el precio que tiene, la calidad de imagen en modo "cuadrantes" es muy mala. Los PCs no reconocen la pantalla redimensionada, y lo que consigues es una imagen distorsionada de cada PC. Por otro lado, a veces se queda "colgado" y hay que reiniciarlo para que se vuelva a mostrar imagen de una de las entradas, y los puertos USB no son conectados correctamente a los PCs, sobre todo cuando se usan teclados Logitech Unified.

Fake Artikel. Die Tastatur und Maus bewegt sich auf alle Computer gleichzeitig. Damit kann man nichts anfangen. Und der Anbieter antwortet auf Anfragen nicht. Voll der Betrug!!!

no mea gustado no tiene instruciones claras y dos el mando no va

Als Quadsplit im Einsatz funktioniert einwandfrei, aber ab und zu rauscht das Bild bzw werden Artefakte sichtbar

Pour regroupé mes ordinateurs en un seul écran et une souris et un clavier....

Le produit ne fonctionnait pas, j'ai demandé le remboursement et je suis partie sur un autre produit.
