Summary: You can use it with three monitors if you turn off your laptop's display (press Windows key + P, then click Second display only). If you are using a DisplayPort adapter, use active. Excellent technical support. At first I couldn't get the monitor to work through a DisplayPort hub with a DisplayPort to DVI adapter. I've encountered this problem before and the solution is to switch to an "active" DisplayPort adapter. I am using "Cable Matters Active DisplayPort to DVI Adapter (Active DP to DVI Adapter) with Eyefinity Technology Support". The hub's marketing says it's capable of extending a desktop to three external monitors at once, but reviews I've read that mention attempts to do so, and answers to "customer questions" about it, said that they only two could get to work. monitor. Although I only needed to connect two monitors to the hub, I wanted to see if I could connect three. After some trial and error (mostly bugs...okay all bugs) I emailed TUTU support asking for help. They emailed a few hours later (impressive) and said the problem was due to my laptop's GPU limitations and I had to turn my laptop's screen off to use the three monitors with the hub. I tried to do this before emailing them and mentioning it in my email so I was upset with their response. Then I realized that maybe I hadn't tried it after I switched to an active DisplayPort adapter. In fact, turning off my laptop screen allowed me to use three monitors with one hub. I was impressed with how quickly and accurately their tech support responded to my issue. I did a little research and found out that using the USB-C port to connect monitors to your PC/Laptop uses the processor's "integrated graphics". processor" (IGP) to drive displays even if the PC/laptop has an "invisible" or external graphics card. The number of *monitors* you can use with the hub is limited by the total number of * Displays* the IGP can handle which is three for Intel/IGP processors (I don't know about AMD) If your laptop screen is controlled by IGP it counts as one display and you can only count two monitors with one Use hub Disabling the screen allows you to use three monitors with one hub.
