I can use when plugged into the HDMI port of the computer however when used with the USB 3.0 - UGA-4kdp I cannot get the resolution set to 2650 x 1080. I have the latest drivers and updates. Highest resolution I can set it at is 190 x 1080.
Thanks for posting!
Can you let me know the exact model number of your LG monitor so I can lookup its specifications online? Can you also confirm you are using a video cable with a DisplayPort connector on both ends of the cable to connect the monitor to the Plugable adapter?
