I have a Lenovo laptop Yoga 730-15IKB with internal GTX1050 gpu with usb-c thunderbolt 3 connection.
I would want to connect an ultrawide monitor from Dell, LG or Samsung with a resolution of 5120x1440 pixels. I now the gtx1050 gpu is capable but lenovo states that their hdmi output is only 4k at 30hz and the usb-c output is also 4k at 30hz (i guess if you use a usb-c cable directly to a monitor)
It seems the usb-c port is also a thunderbolt 3 connection. Can i use the TBT3-DP2X-83 to connect to the display port of the ultrawide 5k monitor? I know your hub has 2 display ports and probably need only one. The ultrawide 5k monitors all have 1 displayport 1.4 and 2 hdmi 2.0 connection.
And does the amount of pcie lanes (2 or 4) on thunderbolt 3 only limits you on how many external displays you can hook up or does it also limits the frequency rate (30 or 60hz) at that high 5k (5110x1440) resolution?
