Detailed description:

From this


I know the possible resolution for the successor UX582LR (according to Blake_ASUS):

The maximum resolution and frequency for UX582LR HDMI 2.1 is 8k 60Hz.

The maximum resolution and frequency for UX582LR Type C is 4k 60Hz.

Currently I connect to both external Ports of my UX581GV two 4k Displays at 60Hz.

On the  Thunderbolt™ 3 via a Displayport and Ethernet Adapter. The Adapter has 2 DisplayPorts, but only 1 is usable. Thunderbolt 3 support 2 Displays with 4K (4096 × 2160 30bpp @ 60 Hz). Maybe a limitation of the Intel UHD or a problem with my Adapter.

The documentatio state that UX581GV has Thunderbolt 3 and HDMI 2.0a.

Is it possible to connect a Dell U4021QW which is 5120 x 2160 resolution at 60 Hz?

Could the TB3 Port of the UX581GV output two 4K Streams as MST (Multi-Stream Transport)?

So that a MST caple 5K Monitor can display [email protected]

Or apply the same limitations as for the UX582LR Type C (4k 60Hz)?

    Hi there,

    Below information for your refernece.

    the max resolution and frequency of UX581GV Type C is also 4K 60HZ,

    so I'm not sure if the 5120 x 2160 option would be shown to you after you connect the monitor and laptop,

    or maybe it would show 5120 x 2160 30Hz.

    And you want to connect 2 monitor to 1 TB3 port?

    I'm also not sure as well. The power supply might not be enough.

    Thank you.


  • UX581GV is still a good Laptop. I have connected two external [email protected] Monitor and have also the interal displays. Of course UX582 is better, but I will stay with UX581 for a while :-)

    Thank you for the clarification. I will stop reading about 5K monitor.
