DisplayPort 8K DP 1.4 Switch Bi-Direction 8K@30Hz 4K@120Hz Splitter Converter for Multiple Source and displays.

It works great and seamless. I am able switch display input by tapping the button.

If purchasing this, ensure you have vesa certified cables, anything else and you will experience problems. The switch works as expected and supports Gsync too. After trying numerous cables from amazon, without luck, I was almost returning the item as faulty, however the following VESA certified cables have worked perfectly, with a 1m input and 3m for outputs. https://www.amazon.co.uk/gp/product/B07HL336L2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

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.

Had this item for two months to connect my gaming monitor to my work laptop, and it worked just fine! Suddenly, when i switched it to use my gaming monitor from the laptop, it would start flickering numeorus times. Does this all the time now. I know the issue is not with the cables, as i've completely swapped them all around with new ones, same issue. Updates my monitor's firmware, same issue. Tried lowering the refresh rate of my monitor, 60hz is the lowest i can go. Same issue. I've since bought a second one, but again it does this straight away. I don't feel these can cope with 4k at 60hz, never mind 120hz.

People complaining about this are not using a designated power socket (from the wall) to power this. I initially used a usb from pc to power it and often got the black screen for a few seconds. Once changed to a socket it’s been flawless. Easy to use and once setup it’s perfect. Use it to switch from sim rig which is 3 monitors, to desk which is one.

I had a specific use case where I needed 2 PCs set up to 2 monitors on 1 desk. These devices work perfectly, essentially a HDMI swapper, just for Displayport. I purchased two of these, one for each monitor. These allowed me to seamlessly switch between PC 1 and PC 2 with just the click of the button on the device, and without me needing to repeatedly unplug and replug any other cables, or play around with the monitor source settings. Make sure your Displayport cables are of high quality to ensure you do not encounter any problems.

I am a software engineer so have a Mac/Pc dual setup. I got this almost 2 years ago but about 6 months ago I started getting fuzziness from my PC side. I originally thought it was a bad cable but swapped it with another 1.4 DP cable and still got the same. I confirmed it wasn’t the PCs graphics card by then swapping which device went into which DP slot on the switcher. Weirdly enough if you left it about 5 mins it does seem to give a clear picture. But now 6 months later the picture never resolved. I had to change my Mac and PC down to 60hz and now the problem is gone. However, the reason I got this is because it said it supports 1.4 and 140hz so it’s not doing what I paid for.

Ive never left an amazon review but I know how tricky it can be to find good reviews for this kind of thing I currently switch between a MacBook Pro (For office / admin work) and a PC (For gaming / Music Production) and finding a decent displayport switch that supports G-Sync but ISN'T crazy expensive has proven difficult I run an ASUS ROG PG348Q Ultrawide monitor and I'm glad to say this unit actually works with 0 problems whatsoever! 100hz and Gsync I took no chances and ordered the same cable that many users here suggested - https://www.amazon.co.uk/gp/product/B07HL7RXKM/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Mi configuracion inicial era desde una 1080ti directo al DP del monitor 4K. Quería meter un mac mini tambien por DP asi que compré este adaptador y estuve probando sólo con la conexion de la 1080ti al adaptador y del adaptador al monitor 4K con un cable DP que tenia por ahi para usar con un portatil en un monitor 1080p. El resultado fatal, parpadeos continuos, se iba la imagen 1 seg y volvia e imposible jugar, asi que pensé en devolverlo pero antes hice un pedido de un cable DP 8K para renovar el viejo y ya de comprar pues de 8K aunque no necesite tanto. He probado con el cable de 8K y perfecto, ni un parpadeo con la 1080ti y desde el mac es un usbc a DP de 4K 60hz y tambien perfecto, ni un parpadeo. Con esto quiere decir que si os da problemas reviseis la calidad de los cables DP que usais, sobre todo del que conecta el adaptador al monitor.

El producto no funciona. La imagen parpadea un par de veces y después no emite señal. Imtenté conectar con diferentes cables pero no sirve. Lo compré para utilizar mi monitor tanto con mi PC personal como la mac del trabajo

This was a good buy. I was a bit weary because display connections and the associated cable and signal properties can be pretty finicky at times, especially with powered equipment such as this. However, it works perfectly and switches back and forth as advertised, even providing me with the 144Hz my gaming rig outputs. Makes life just a bit easier, in stead of swapping inputs on the backside of the screen, I can now just press a button to switch display input, and another button to switch my mouse and keyboard back and forth as well (which is, of course, another device)

I have this device switching the signal coming from my PC between my 4k160hz monitor, and my 4k120hz TV. I was concerned that it wouldn't be able to achieve my monitor's resolution at 160hz, but it has been working correctly so far. One thing I noticed was that the picture will cut out periodically if the device is not supplied enough power. I originally had it powered via the USB port on the back of my monitor, but this caused a lot of cutting out. I tried a generic 5v1A apple power brick and it faired better, but still cut out periodically. I finally tried it with a 5v4.8A power brick and it has been working as well as I want it to after that.

Wszystko działa jak powinno. Jest super.
