Hello! I just purchased your UGA-4KDP unit from Amazon.
Not working at 3820/2160 - 30Hz. Does work at 1920x1080.
How do I change the internal setups in Windows 8.1 on my Lenovo Yoga 2 Pro laptop to get it to work?
I am connecting to a Seiki 50" 4K monitor that works fine on my desktop (Windows 8.1 with PNY Quadro 410 card). I have the monitor technical details in a file if you need them.
