    It does what it says on the tin… most of the time
    It works great, I have it set up between my Laptop with a HDMI to USB-C cable and my Gaming PC with a HDMI Cable from the back of my machine. I upgraded both my PC and output to my Screen and stuck it with 3M removable ‘Velcro’ strips to the wall.My only annoyance with the device is that every now and then it will not register when I switched the PC/Laptop on but unplugging the cable that leads to the Screen and putting it back in solves that… its an annoyance and for the price I can deal with that.For the price and knowing what I know now… I would buy it again if I had to.

    Cheap (but good) multimonitor KVM setup.
    I bought two of these and a switching USB hub to create a cheap multimonitor KVM setup for around $100 (vs. dual-link KVMs starting at $250+ and easily hitting $500 for a decent quality one, and those don’t necessarily support DP1.3+). This makes it easy for me to switch each monitor, and the peripherals, between my work and home machines while WFH.Quality-wise the device has a metal case and feels solid. I plan on mounting mine to the back of my monitor, but haven’t quite worked that out how yet (possibly command strips but one monitor has a more curved surface that will make that difficult).Switching requires the physical press of a button and there doesn’t appear to be any alternatives. I’m tempted to open mine up to see how easy it would be to wire another microswitch so they can be relocated anywhere. Power is provided via a USB to common D/C power plug adapter (none of the data ports are connected so you can’t use USB to switch it).You need to provide your own DP cables.On the work machine I’m using the built in DP ports on the motherboard.I’m my personal machine I have an EVGA 2080Ti.Monitors are:- Asus XB271HU connected to DP switch “Alpha” (2560×1440@144Hz GSync)- Dell 2412m connected to DP switch “Bravo” (1920×1200@60Hz)- Dell 2412m directly connected to my personal machineCables are important. Initially I was using 6ft cables everywhere (DP1.3 I think?), and had flickering / noise on the 1440p monitor periodically, and regularly while gaming. IIRC They recommend staying under 10ft total, so I swapped out the monitor to switch cables with 3ft versions and that almost completely resolved the issues.Cables:- Between monitors and switch: 3ft DP1.4, specifically: Between home PC and switch: 6ft DP 1.4, specifically: Between work PC and switch: 10ft DP 1.3(?), specifically: (I already owned these and they are no longer available; I haven’t had issues, but if I saw some I would buy more of the 6ft CableMatters ones I link above)So regarding the issues I mentioned before. When I switched to the 3ft cables to run to the monitors I saw almost all issues go away. I periodically–that is, maybe once a day, probably less–have the signal flicker and my GSync monitor goes black for a second then comes back and everything is fine. It hasn’t bothered me enough to look into it further. The older U2412m hasn’t had any issues.When switching between the monitors it is effectively unplugging the monitor from the device, which works great for me. I can have between 1 and 3 monitors dedicated to my personal machine, and 1 or 2 monitors for the work machine.The only other weird callout I have is that one of the two I bought defaults to input 1, and the other defaults to input 2. I’ve tried various combinations of plugged in devices and powering the switch off and on and nothing seems to change this. I’ve posted the question and hopefully the manufacturer responds.Pros:- No issues once I followed the manufacturers guidelines, though I’m not trying to run 8K and I bet I would have problems with that based on my experience. But it fits my needs and I was reasonably certain it would from reading the reviews before I bought it.- Switches fairly quickly (I’d say within a second, maybe two, though I haven’t timed it), and Windows is quick to detect the new monitor and adjust the desktop of the new machine (it also does it’s best to move Windows back to where they were, though this isn’t perfect…but I can’t judge this device for that problem)- Indicator light is a blue LED and is quite visible- Cables clip in solidly and feel secure with no flex or wiggle. D/C power connected feels much more secure than a micro USB would- I’m powering them from my monitors USB ports so they turn off when I turn off the monitorCons:- Need to press a physical switch to adjust input- Bright blue indicator could be annoying in a dark room, but easy to cover with electrical tape- I get the odd signal synchronization issue on my GSync monitor causing it to effectively lose signal and then get it back over a split second. This happens at most once a day.- No way to set the default input and one is defaulting to 1 while the other is defaulting 2Caveats:- Read the reviews before you buy one and you should be able to figure out if this will work for your monitors / setup- Doesn’t appear to be any out of the box way of using a remotely mounted switch, so you’ll want to keep it in arms reach on your desk or behind a monitor

    funktioniert gut, wenn A.I.S. Schirmung verwendet wird
    Am Anfang gabs nur schwarzen Bildschirm, das Stromversorgungskabel am Monitor lag zu dicht an der Displayport Leitung, mit Aluminiumfolie abgeschrmt liefs besser. Ich hatte dann ab und zu Aussetzer beim Bild, dann habe ich mir qualitäts Monitorkabel bestellt mit A.I.S. Schirm ( seitdem tadellos stabiles Bild!

    Requires a specific setup to work with demanding displays, but it DOES work.
    You may have seen some reviewers saying that this doesn’t work with their high refresh rate displays. I can tell you that this is incorrect, and – barring legitimately faulty devices – this switch can definitely operate as advertised. It’s just that to run it at the very edge of spec you will almost certainly need to purchase a specific kind of DisplayPort cables to go with it.To provide some details on my setup in advance: – Output device: RTX 3080 graphics card – Input device 1: Acer Predator X34P monitor (1440p Ultrawide / 3440×1440@120hz) – Input device 2: Philips 558M1RY/75 (4K / 3840×2160@120hz).These are both in the class of screens for which other reviewers have reported issues.When I first set up the switch, I encountered unusual behaviour. The more demanding 4k monitor ran mostly fine but had infrequent bursts of static, while the slightly less demanding 1440p ultrawide became totally unusable. The screen would constantly lose and find the signal again over and over, causing it to blink on and off.The cables I was using at the time were specially purchased Dynamix Displayport 1.4 cables that had previously been working satisfactorily for these displays. After some digging through other reviews for this switch I found that the single biggest factors causing issues are interference from other cables, and the length and quality of the cables used.Not all DisplayPort cables are made equal. Quite frequently the default ones bundled with your display may not even meet the minimums of the specification if they were put through a tester. And If you go and buy ones from the store, they still might not be actually certified cables.Here is what you need to make sure this switch will operate correctly right up to the edge of spec: – The total cable length to either monitor must not exceed 10 feet / 3 meters. (I have a 1 meter cable from the output to the switch, and then 2 meter cables from the switch to each display) – All three cables MUST BE a minimum of DisplayPort version 1.4. – You should specially purchase your cables. To be safe, I recommend purchasing DisplayPort Certified cables, but understand that can be quite expensive. – If your cables will be in close proximity to other cables, seek out a brand which advertises additional layers of shielding. – If you have a large number of USB peripherals coming out of your computer then your motherboard/laptop may struggle to deliver the power the switch requires. Try plugging it into a USB charging port on a multi-board, or USB type A wall charger.When meeting all the above requirements I can confirm this switch works flawlessly and I highly recommend it, especially for this price.A few final notes:The build quality is good, with a sturdy metal housing. The indicator lights are unnecessarily bright, so I suggest putting a bit of masking tape over them. They’re so bright they’ll likely still be visible through whatever you cover them with, but will no longer light up a whole room at night.Overall, I’m very pleased with this purchase and it fulfils my needs perfectly.

    Leichte Mängel in Beschreibung, aber (Sehr) GUT
    Das Gerät ist Robust und hält genau das Was es verspricht. Alle 3 Ports lassen sich Problemlos wechseln, sowohl mit 3 Computern und einem Monitor als auch mit 3 Monitoren und einem Computer.Etwas nervig ist leider die Anordnung der Anschlüsse. Durch Bestückung von Vorder- und Rück-Seite landet ein Teil des Kabelchaos halt doch wieder im sichtbaren Bereich auf dem Schreibtisch. Hier wäre noch besser das Gehäuse lieber etwas breiter zu gestallten und dafür alle Ein- und Ausgänge auf einer Seite anzubringen.Auch die LED für die derzeit ausgewählte Option ist sehr schwer zu erkennen wenn das Gerät flach auf dem Tisch in etwas Entfernung liegt.Vorsicht: Es wird ein USB-2 Mini 5V Strom Input benötigt zu dem weder Kabel noch Netzteil beiliegen. Wenn dieser nicht eingesteckt ist, dann funktioniert das Gerät auch nicht. In der Produktbeschreibung war dies leider auch nicht direkt ersichtlich.Diese Punkte bringen Punktabzug. Ansonsten bin ich sogar überrascht, dass der Switch bei dem Preis so stabil ist und zuverlässig funktioniert.

    Works well and well made
    Works nicely at 3840×2160 60Hz and split three computers into one monitor. good value for money. seems well made.

  8. Imad-L

    works but
    It works just fine but you need usb power plug with 5v >= 2A okplug with 5v < 2A faultyI hope the seller mentioned that is description.

    Works for my GSYNC Ultrawide Monitor (AW3821DW)
    There’s been a lot of confusion in the review whether it supports gsync and for my monitor (AW3821DW) it does. I connected it to my monitor and one to a D6000 dell dock for my thunderbolt devices Macbook/Laptop/Ipad etc. Running without issue now for a month. Switching is quick, make sure that you are powering the switch with a proper 5V that could be why some people are having issues.

    May have compatibility issues with docks
    I hadn’t expected any compatibility concerns with a switch like this as I had expected that it would, in-effect, work like unplugging one display port cable and plugging in another. My home setup is a desktop computer and a laptop with a dock both going to the same monitor.With the first dock that I tried the computer detected the monitor but no output was displayed. I was able to source another dock to test and this one worked. The only technical difference I can see is that the working dock supports Dual-Mode DisplayPort (DP++) but I don’t see any evidence of signal conversion happening so I don’t know if that is relevant.I contacted the seller who said he does not recommend using this switcher with any type of dock. He was also unwilling to provide any technical information about what types of display port cables this switcher supports or has been tested with. As such, I wouldn’t recommend this product as it is only a matter of luck if your devices will work with it.
