I have a 20BT0018US model and it has a native HDMI port & a Mini Display Port
The Specifications for this Model state:
Your computer supports the following video resolution, if the external monitor also supports that resolution.
• Up to 1920 x 1200, with an external display connected to the VGA connector
• Up to 2560 x 1600, with an external display connected to the mini DisplayPort connector
• Up to 4096 x 2160, with an external display connected to the HDMI connector
I have attached two different HDMI cables to three different monitors.
Some were native HDMI, others had HDMI to DVI converters on them.
All scenarios result in a maximum screen resolution of 1920 x 1080
Althought the monitors support a greater screen resolution, I can't seem to get anything higher ??
Has anyone resolved this ?

Interesting Test Case.
I borrowed a Mini DisplayPort Adapter- VGA and tested with the same monitor that the HDMI cable is plugged into.
I received a screen resolution of 2560 x 1600 right away !
I switch back to HDMI and it goes down to 1920 x 1200.
So I know the Video Card is capable of higher resolutions.
The issue must be with the native HDMI port.
Is anyone aware of a Formware Bug for this ? Or maybe Windows 10 driver issue ?

Or maybe the cable. Older spec HDMI cables may not be able to support resolutions above 1920x1200.

Thanks for your reply.
I tried two different cables.
1) HDMI to DVI
2) HDMI to HDMI with a ATI HDMI to DVI converter.
Two different monitors, two different cables.
The only test I have not tried yet is to try HDMI to HDMI native to the monitor.
This is my next use-case.
