HDMI (4k) port is not working
I’m using the Triple Display Docking Station with a laptop, which I plan to extend/duplicate upon two monitors. My laptop is a ThinkPad but does not have a USB-C port, so I am currently using a USB cable to connect to the laptop and the other end is USB-C, which is connected to the Triple Display Dock. Both of my monitors are Acer 27 inch (model: S271HL DBID), and I am connecting both to the Triple Dock via HDMI cables. The 2K HDMI port is functioning with both monitors, but the 4K HDMI port does not work with either, so I know my cables and monitors are in good shape.
Why can’t I get the 4K HDMI port to function and display my second monitor? The 2K HDMI port works perfect.
Is there a way I can connect and charge my ThinkPad, which does not have a USB-C port, using USB or it’s power cord through an adapter of some kind? The power cable that my laptop uses is Lenova 20V 3.25A 65W Ac Laptop Power Adapter Charger and I would love to power it through the Triple Dock, but I understand this may not be possible.
