Amazon Basics Bi-Directional USB-C to DisplayPort Cable, Thunderbolt 3/4 Compatible, 4K@60Hz, DP Alt Mode, Plug & Play, 6-foot, Black

It's incredible how hard it is to find something that goes from a GPU to a portable monitor that accepts a signal on a USB-C port. 99.9% of the time such a thing isn't needed, so I'm glad this exists at all. I have an Arzopa 13" 2560x1600 portable monitor that I use with my laptop, but mostly use it at home under my main monitor. The problem with the Arzopa monitor is that it has a really dodgy connection if you use mini HDMI as the input and would flicker constantly or fail to work entirely. I didn't know that was the problem until I read a review here on Amazon, which sent me on a quest to find a way to connect it to my desktop via DP, since I have 3 of those and only 1 HDMI (already used). It seems the HDMI port was a checkbox rather than something they wanted people to actually use. Anyway, the cable works and it fixed my problem!

This works great for my portable monitor! Very easy to plug in and get going. Great signal and durablity!

The PC this is used on has one HDMI and two DisplayPorts. The two monitors are Dell 27" 4K and both have two HDMI ports and one USB-C-DP (DisplayPort Alternative Mode). I used HDMI on one monitor and a Plugable active DisplayPort (PC) to HDMI (monitor) adapter/converter for the second monitor. It worked, but the second monitor would not wake up after waking the PC from sleeping. I had to unplug the DisplayPort cable and plug it back in to get it to work. I replaced the DP to HDMI adapter with this AmazonBasics bidirectional DP to USB-C-DP cable and the issue is resolved. The monitors now work as they should. It's interesting that, to my knowledge, there are no single directional DisplayPort to USB-C-DP cables. A single directional cable will not work in the scenario because those cables only send video output from USB-C-DP on the PC to DisplayPort on the monitor. This AmazonBasics cable sends video output either way. It's an awesome product for an awesome price.

amazon basics accessories like these are always decent

I have two Samsung M8 Smart Displays; for inputs they support USB-C/Thunderbolt or (micro) HDMI. My Lenovo P15 Gen 2 laptop is attached to a Lenovo Thunderbolt 4 Workstation dock which has 1 Thunderbolt, 1 HDMI, and 2 DisplayPort outputs. The monitors individually work fine when attached to the Thunderbolt connection, but since they don't support daisy-chaining I can connect only one of them that way. Connecting the 2nd one to HDMI worked, sort of, but the HDMI-connected display would change resolution and end up as the primary display whenever the laptop's power profile would turn them off after a period of inactivity. I had other displays connected to the dock's DisplayPort ports previously and did not experience any issues, so my search for an option to connect from DisplayPort to USB-C turned up this cable. And I'm happy to say that it seems to have worked as I hoped!

Unfortunately did not work for my SFF pc. I am using this to display on my arzopa monitor and I cant get nothing to display. Just a FYI for anyone who has a Arzopa monitor. This is the second cable I tried now..... on to the next

So this cable is truly "bi-directional" with one very important caveat. It has active electronics inside it that need power. Depending on the source and destination devices this may not exist. In the case of connecting it to a Thinkvision M14 it works correctly when paired with a USB Power Delivery (PD) compatible charger as that power will pass through the monitor and provide the needed power for the circuitry in the cable. When connecting this monitor to a graphics card in a desktop or eGPU enclosure it will not provide power from the graphics card side into the cable so the monitor needs to provide power. In the case of fixed monitors such as LG Ultrafines and Apple displays they provide power to devices over the usb-c ports. In the case of monitors such as the Asus XG17AHP this cable will not work due to the Asus monitor not passing through USB-PD from an external power source to the cable so the cable doesn't receive any power. Unfortunately the only solution for that monitor is to use the wacom link cable B06WGM6KDN

I purchased the Amazon Basics Bi-Directional USB-C to DisplayPort Cable, 6-foot version with the hope of “USB-C full featured” capabilities, which means you can use that single port to transfer data, audio, video, and power. My issue is my connection begins with the computer's Graphics Processing Unit (GPU) DisplayPort to my external portable monitor that has a “full featured” USB-C port. The VESA DisplayPort standard is a device that can draw a maximum of 0.5A at 3.3V, which is not enough power supplied to the USB-C port on the monitor. If you have the reverse scenario, I believe the (computer) GPU USB-C port would power the (monitor) DisplayPort. Regardless, the cable provides excellent signal and video quality. I am happy with the purchase.

Kabel działa bez problemu z laptopem HP Elitebook G3 na zintegrowanej grafice Intel 520 i obsługuje rozdzielczość 3440x1440 przy 100hz. Displayport jest podłączony do laptopa, a USB-C do monitora. Polecam

it does work to connect my pc to an usb-c monitor without breaking the bank

Me pasé al Bi-Directional después de que el otro cable de Amazon Basics (el Unidirectional con conectores grises) me dejara tirado a las dos semanas. Y la verdad es que ha sido un acierto. Lleva ya casi un año enchufado a mi MacBook y un monitor 4K de 27", y funciona como el primer día. Lo conecto y desconecto varias veces al día porque me muevo con el portátil, y antes con otros cables notaba que al cabo de unos meses empezaban los problemas. Este ni se inmuta. Tiene un clip en el conector del DisplayPort que hace que quede bien fijado en el monitor y no se suelte. Ojo que si tu monitor tiene el puerto un poco hundido, puede costar un poco sacarlo, pero para mí eso es más ventaja que inconveniente. De los mejores cables que he tenido para esta conexión. Y mira que he ido cambiando cada medio año.

I picked up this Amazon Basics Bi-Directional USB-C to DisplayPort cable (1.8 metres) to connect my laptop to an external 4K monitor, and it’s been flawless from day one. The build quality is solid, with a durable outer coating and firm connectors that plug in securely. The bi-directional functionality is a huge bonus – I can use it to connect a USB-C device to a DisplayPort monitor, or vice versa if needed. It works perfectly with my MacBook and a 4K DisplayPort monitor, delivering crisp, clear video with no lag, flickering, or dropouts. The 1.8m length is ideal – long enough to reach between devices without being messy or tangled. It’s also lightweight and easy to travel with. Overall, a great value cable that lives up to the Amazon Basics name: simple, reliable, and does exactly what it’s supposed to do. Highly recommended!

Questo cavo è stupendo, funziona perfettamente, peccato solo esista questa metratura così corta!
