[NAME]  The XPS 15 model introduced in 2021 is the 9510.  The 9500 launched in 2020.  The XPS 15 9500 is an HBR2 system, which means that in order to run 4K 60 Hz, you need a USB-C connection that is carrying only video and USB 2.0 (not 3.x) or Thunderbolt.  So a basic USB-C to HDMI 2.0 adapter/cable would work, but a multi-purpose adapter that set up the USB-C link for video + USB 3.x data, such as Dell's bundled adapter, would not.  Thunderbolt would allow dual 4K 60 Hz.By comparison, the 9510 is an HBR3 system, which is capable of running 4K 60 Hz + USB 3.x over regular USB-C simultaneously.  With that system, Dell's bundled adapter would allow 4K 60 Hz.With both systems, any of the ports would be usable for USB-C connectivity, and the left side ports would be usable for Thunderbolt.  But you can also connect the power supply to any of those ports.  You're not required to connect the power source to the right-side port as you seem to believe based on your question about that.The only difference between the WD19 "S" models and the non-S models is that the "S" models dropped the 3.5 mm audio jack.  Something about the global semiconductor shortage prevented Dell from sourcing those jacks or the audio chips that run them, so they dropped that feature in order to continue producing docks.
Hi there, I've just bought a Dell XPS 15 - 9500 - with intel 10750H + Nvidia 1650ti. I am planning to use the XPS 15 laptop with my Samsung 4k monitor - which is working fine with my older laptop at 4k 60hz via HDMI 2.0 third party dongle. I keep my current older laptop constantly charged whilst hooked up to 4k 60hz monitor. I have been reading multiple threads on the XPS 15 support for 4k 60hz monitors. Could anyone clarify if XPS 15 would be able to 4k 60hz monitor via: 1. The provided dongle with the XPS 15? there are some threads indicating the Dell provided dongle only supports 4k 30hz, which is not ideal. 2. A USB C to HDMI 2.0, or USB C to Display Port - using any of the two left side XPS 15 thunderbolt ports? If I have to use the right side USB C port, does it mean I cannot use direct power supply for my laptop?  I want to avoid the expensive option of having to buy the WD 19 TB dock. I noticed it is out of stock from the Dell Store. If the only option is to buy the dock, does the WD 19 TBS (with a 'S' in the name) work just as well? Many thanks
