Hello everyone. I've just bought and external 1440p monitor (Philips 275E1S/00) which I will use alongside my Lenovo 530s (14").

However, I can't set the monitor resolution to 1440p. The maximum I can set is 1080p. I'm using the included HDMI cable in the box. The monitor spec sheet says "The maximum resolution works for either HDMI input or DP input".

I'm using Linux and I tried setting a custom resolution using xrandr but that didn't work. I also tested it on Windows and nope, 1080p is still the maximum resolution.

 

 

Edit: apparently in Lenovo's spec sheet the maxium output resolution over HDMI is listed as 1080p. Oh well, guess that's it. The USB type c port on the laptop doesn't support display port so there aren't any other options.
