DELL XPS 15 9530 - Max HDMI/Display-Port Resolutions

Hi All/Dell,

The HDMI output or the display port converted to HDMI does not drive my 2560x1600 DVI/HDMI external monitor.

What is the max resolution that can be driven by the HDMI and display port?

If I get a new display port external monitor, I want to make sure the display port output from the laptop can drive it.

I looked all over the User Manual, spec sheet, etc and could not find this information.

Thanks,

Carlton.
