I am pulling my hair out trying to figure this out; hoping you all can help me out. My work laptop is a 1.5 year old HP Zbook G3 with an nVidia Quadro M1000M. At work, it is hooked up to an HP thunderbolt 3 dock which is pushing 2 1440p monitors (via displayports plugged into the dock), and is working fine.

At home, I have a Dell U2713HM 1440p monitor (HDMI 1.4). No matter what I do though, I can't get my laptop to display at 1440p on this monitor; it only will display at 1080p. I've tried connecting with several different brand new HDMI 2.0 cables (Laptop HDMI port to Monitor HDMI port) and I've tried connecting from the thunderbolt 3 port on laptop to HDMI port on monitor using a brand new USB-C to HDMI dongle that says it supports 4K@30Hz.

Any idea why this won't work for me? I've updated to all the latest drivers. as far as I can tell. This has been driving me nuts for weeks.

    Seems that you need a DisplayPort or a docking station to reach that resolution – spike_66 Feb 13 '18 at 8:57
  • That doesn't make sense becuase I tried using a 4k capable HDMI cable through a 4k capable dongle connected to the 4k capable thunderbolt 3 port. – Crescent Feb 14 '18 at 16:08

Well, I got it to work by using HDMI output on laptop to HDMI input on monitor, and then creating a custom resolution in the nVidia control panel: 2560x1440@30Hz. Would not do 60Hz unfortunately.
