Detailed description：I'm trying to output my Zenbook Pro Duo UX582 system to a Dell U4021QW which is 5120 x 2160 resolution. The max refresh rate I can get when plugged in either via HDMI or USB-C Thunderbolt is 30Hz instead of 60Hz. I've tried a a variety of cables, reinstalled video drivers...nothing helps. If I drop the resolution down to anything less than the native resolution 60Hz is available but not at the native screen resolution of 5120 x 2160. I would think it could support considering USB-C Thunderbolt 3. I've tried using the screen as an extended screen and as my only screen with the laptop lid open and closed. No difference.
Monitor specs show: Native Resolution
WUHD 5120 x 2160 (DisplayPort: 60 Hz, HDMI: 30 Hz)
But why wouldn't this work using the USB-C Thunderbolt ports which are advertised to support DisplayPort connection, and the 40 Gbps bandwidth lets you connect an external 8K display or two 4K UHD displays.
Any suggestions? Thanks!
