Why is the screen flickering or going black?
1. Insufficient Power Supply
Some devices may have a weaker power supply capacity for the docking station, which can lead to insufficient power and screen flickering. Therefore, it is necessary to connect the charger for power supply when using it.
2. Check HDMI Port Connection
Because the HDMI interface has no locking mechanism, it is easy to cause the screen to blink due to poor contact. Check that the HDMI cable is firmly inserted into the port, and try to re-insert it to ensure good contact.
3. HDMI Cable Selection
Avoid using HDMI cables larger than 5 meters; Avoid using HDMI to VGA and HDMI to DP cables. Longer cables may result in more significant signal attenuation, mainly due to inadequate impedance and shielding. In addition, the use of other adapter cables constitutes a secondary conversion, which is likely to affect transmission power and stability.
4. Display Compatibility Issues
You can try replacing the display to see if the flickering issue persists, as some displays with weaker signal reception may exhibit flickering.

I have never needed to use two monitors, until my husband started trading stocks and the program he uses requires multiple monitors to track everything. This USB C to Dual HDMI Adapter 4K@60hz was really just plug and play. I am not as tech savvy as I used to be but this was easy and works great. Price is great.

I wanted this to extend another HDMI monitor on my Windows desktop, but the second monitor wasn't able to get a signal when connected to this device... for the purpose I needed it for, it failed, I returned it. Find something else!

My laptop screen shows text so small it is hard to read. J always carry a second monitor for myself, and often need to also connect to a large tv in the room for others to also see my presentations. This dongle allows this function. This makes my professional life so much easier!

The adapter supports both extended and mirrored display modes, allowing users to either extend their desktop for multitasking or mirror their primary display to an external monitor for presentations. This flexibility is beneficial for different work setups and use cases, from video editing to data analysis.

This is well made and sturdy. It should stand the test of time for normal use. This has allowed me to have a 3 monitor setup with my gaming laptop. Connection was easy and everything works well. I can get a lot more done with 3 monitors working at once and gaming is a whole lot more fun.

Nothing fancy here, but it does the job. It seems like a good quality product. It splits the video into two via HDMI. There is no visible quality loss at all.

This worked pretty seamlessly to extend the screen of both my personal laptop (mac) and my work laptop (Dell). However, I would note that the size/shape is a little awkward and would benefit from a longer cord to connect to the laptop in general, and a slightly larger/sturdier box. I found myself worried about the cord being constantly strained at a strange angle due to the two heavier/thicker HDMI cords which pull the light/thin box at a strange angle. It will work for now, but time will tell to see if it lasts.
