Switch between work and game on a button
I was annoyed about dealing with my work and life on a small screen. This KVM switch came to my eyes, actually at first time I thought it was too expensive until I finally set it up and use it. It is worth the price. What impressed me first is the build quality, it looks not cheap at all. It can switch between 2 PCs in just 2 seconds with 60Hz 4K resolution. I compared a lot before my purchase, and similar KVMs at the about price just support 30Hz 4K, excellent! BTW, it works great with my Mac and Logitech wireless mouse.

Very good product
Straight forward to instal and use out of box. However a remote to switch would have been improved the experience

Good kit but jammed my router
Nothing wrong with this KVM. Nice build, sensible configuration BUT it is a powered system, i.e. what is known as a 'managed switch'. What I did not know is that these can send a router haywire and I my case I have a Sky router which does not like this device. Who knew? Well, I found out the hard way! (Sky Community also gave me helpful guidance). While the device worked fine, switching between PCs simply caused the router to drop its connection to the various Sky boxes in my house! There are fixes - apparently setting your network adapter to generate Jumbo Frames can work but not in this case - but that didn't work for me. So, thank goodness for Amazon's fabulous no quibbles returns policy. I sent it back and went for a passive device instead. That works fine. To emphasise - this was not a problem with the device itself. It worked well when my Sky boxes were offline but I could not get it to cooperate when live. As I say, nice build quality but conflicts with the Sky router. If you have a regular router that you are able to manage (Sky is fussy) then this will likely work for you.

Really good - works a treat
I've been using it to share monitors/keyboard, mouse and even an Audio Interface! between 2 PCs and it works a treat. Nicely done AV Access! Great Product!

It does what it says
Whilst functional there are some quirks of the kvm switch you need to be understanding of. For example my monitors have built in speakers however the audio that comes from it when utilising the kvm switch is heavily static or sometimes it doesn't work. Also the keyboard port within the switch doesn't behave great, my issue arises with gaming where sometimes the keyboard just stops responding in certain titles (mainly overwatch). Taking stuff like this in mind is important which is why I'll probably be searching for an upgrade on the meantime. However for the time being it does what it says on the tin (kind of)

AV Access KVM Switch 2 Monitore
Habe das Gerät vor 2 Monaten gekauft und betreibe 2 Computer, 2 Monitore, Bluetooth Maus + Keyboard und ab und zu eine externe Festplatte. Das Gerät ist zwar nicht ganz günstig, aber bisher bin ich sehr zufrieden. Alle angeschlossenen Peripheriegeräte funktionieren einwandfrei.

Works great
Works really well, the build quality is awesome. I like that fact that is has a power button and it is externally powered. I use it with my Lenovo ThinkPad and MacBook Pro M2, and it works really well on single 4K 60Hz screen. The hotkey switching could be faster but I that does not bother me much.

Great value and solid performance so far!
Product working as expected, the quality is great and hopefully it will perform well for a long time. I purchased this kvm for my home office, it need to be connected with 2 HDMI cables and 1 USB-B cable in PC and laptop ends. It make me easy to switch with 2 PCs, so far I'm loving it. The switch features 3 USB 3.0 ports, 1 USB 1.1 port, allowing me to connect all of my necessary peripherals including wireless keyboard, mouse and external USB drives, without any issues. Not like other switches, this unit also includes 3.5mm audio port, I don't need to long cable headset again to enjoy gaming and music. The switch is also well-built and sturdy, grey metel body making it a reliable addition to my work setup. They added a nice additional feature-locked power cord connector, which prevent power cord loose. This is amazing design. Overall, it was very nice for my application. I highly recommend AV Access KVM switch.

Guter Switch
Der AV Access KVM Switch macht mit seinem hochwertigen Metallgehäuse und sauberer Verarbeitung schon auf den ersten Blick einen guten Eindruck. Aber zum Glück sieht er nicht nur gut aus, sondern macht auch seinen Job perfekt. Ich habe den Switch an mehreren PCs, Laptops und sogar in Verbindung mit Konsolen getestet und hatte nirgends Probleme irgendwelcher Art. Von 1080p bis 4K und von 60Hz bis 144Hz lief alles ohne Probleme, genau wie die USB Schnittstellen. Ich konnte keinerlei Verzögerungen oder Einbußen in der Bildqualität feststellen. Dazu kommt die nette Optik des Switches, die bereits erwähnte hervorragende Qualität, so wie die gute Benutzerfreundlichkeit, durch die man nicht einmal eine Anleitung benötigt. Bei KVM Switches sind Bewertungen manchmal ein bisschen schwierig wenn es nichts zu meckern gibt, denn dann kann man im Grunde nur sagen "Alles töfte", aber das ist ja dann im Grunde auch die einzige Information die man braucht. Mir gefällt er sehr gut und alles funktioniert wunderbar. Und obwohl er nicht unbedingt günstig ist, ist der Preis durchaus gängig für Switche dieser Art. Von daher: Volle Empfehlung von mir.
