Hi - I bought this product in August/September last year when I was in the UK. At the time, I noticed the HDMI port didn’t work well with my 2 monitors and 2 laptops but I managed to connect 2 monitors using the DPs, which is what I needed then and I assumed there could be a later driver fix.
I am now in China trying the HDMI port again with 3 other monitors (for a total of 5 monitors) and am experiencing issues with all of them on two different laptops. It is not the cable - I have tried several and experience the same issue. I also installed the latest Displaylink software. I also tried removing registry settings (a suggested fix for a similar reported issue in this forum) and no luck.
The two laptops are a Lenovo X1 Carbon 5th Generation running Windows 10 and a Microsoft Surface Book 2. When I connect any monitor to the HDMI port when the hub is connected to the Lenovo X1 Carbon, WIndows 10 recognizes the attached monitor but the monitor reports that it is not receiving any signal. When I connect any monitor to the HDMI port when the hub is connected to the Windows Surface Book 2, Windows 10 recognizes the monitor and the monitor shows the display but it flickers every few seconds. I noticed that over time and if I plug more items into the hub, the flickering seems to increase in frequency.
Naturally I am disappointed as I purchased this product to replace a reasonable dual monitor solution and my hope was to have a superior more stable solution that I could later extend to three monitors. So I am disappointed to have spent extra on this solution (including extra cables as I was forced to use the DP ports) and to have spent a couple of days of personal time fiddling with it to no avail. I hope I can get this resolved without spending too much more time on this, especially as it increasingly looks like a hub with a faulty HDMI function and would therefore be a warranty issue.
Please let me know.
