I purchased this computer here - http://www.johnlewis.com/hp-envy-phoenix-860-000na-desktop-pc-intel-core-i7-16gb-ram-2tb-128gb-ssd-metal/p2285574. It has 1x HDMI and a display port. I am connecting two Dell 27" U2715H displays from here http://www.ebuyer.com/697916-dell-u2715h-27-qhd-hdmi-monitor-210-adsn
I am connecting one monitor via miniDP and the other via HDMI using a 1.4 cable. Unfortunately only the main monitor is displaying 2560x1440 resolution through the miniDP, where as the HDMI is only displaying 1920x1080 and this shows as the maximum resolution in the windows display centre.
Of course I want both monitors to be displaying 2560x1440 as advertised at 60hz.
Please help. Thanks in advance.
