Yoga 520-14IKB HDMI output

Is there any way to get higher than 1080p resolution on an external monitor through HDMI from a Yogo 150 14-IKB?

 

I've just bought a monitor that can do up to 2560x1440 @ 60Hz (as it can when connected to my other laptop which has a 16" screen that natively runs 1366x768, using AMD Radeon R5 graphics) but it appears that the Yoga 520-14IKB can't do so.

 

What I've tried so far is to update the drivers on the Yoga for my new monitor, so that Windows 10 doesn't use the default PnP monitor driver, but this didn't immediately unlock any other settings. The default maximum resolution through the output is 1920x1080, which means that pixel size on the external (24") monitor is >1.5x pixel size on my laptop screen (14").

 

I've looked at the Intel HD Graphics Control Panel (as it runs Intel HD 610 graphics), and I can add this extra resolution as a custom resolution, but the monitor claims the signal is out of range when I try the 2560x1440 (60Hz) that I can get from the other graphics chipset.

 

Is there anything else to try?

Actually, though further inspection on my 15.6" laptop, the output is downsampled in software before going through HDMI at a 1920x1080 resolution, which is what the monitor can use, so it looks like it might be a driver issue rather than anything hardware related.
