MavenPA, The reason you might see the monitor listed double is that the monitor supports input via the type-c, there is no need to connect an HDMI connection. There are no downsides to using either, except without the usb-c cable, you would not be able to use the ports on the monitor. The video output ports on the monitor are through the Intel Graphics.
I just purchased the following equipment: Dell XPS 9510 laptop Dell WD19TB Docking Station 2x Dell S2722DC USB-C Monitors Not knowing any better, I connected each of the 2 monitors to the docking station using HDMI->Displayport cables, I also connected the USB-C port of each monitor to a USB-C port on the docking station as the manual states that this is required in order to use the various USB ports on the monitors. I am using Windows 11 and it reports that I have 4 monitors. Using the "Identify" function in System/Display, the monitors show up as Displays 3 and 4. I set Display 1 and Display 2 to "Disconnect the display". Would I be correct in assuming that since I have a Thunderbolt laptop, I did not need to connect the monitors using the HDMI ports to the Displayport on the docking station and that is why Windows thinks I have 4 displays (2x USB-C and 2x Displayport)? Should I disconnect the HDMI/Displayport cables and leave the USB-C as is? Any downside to this? Bonus points if you can tell me why Windows 11 System/Display/Advanced Display reports that both monitors 3 and 4 are "Connect to Intel(R) UHD Graphics" - why doesn't it say Nvidia GeForce RTX 3050 Ti? Is it because the Nvidia is integrated and passes through the Intel UHD? Clearly, I lack knowledge when it comes to GPUs and advanced display configurations. Thank you!
