Trouble getting two monitors both working

Hello,

I have a laptop with an i7 8565 CPU and intel 620 graphics. I just got a QHD monitor (Acer ET322QU) (Mon1) connected via either DisplayPort or HDMIN to go with my old 1080p monitor (Acer G276HL) (Mon2) connected via HDMI. Windows 10, no gaming, up to date graphics drivers.

I can get one monitor working appropriately, either

- Mon1 at full 1440p resolution at 60Hz and Mon2 at 1080i 30Hz
or
- Mon1 at 1080p (which defeats the purpose of the large monitor and Windows appears to do some ugly scaling with) and Mon2 at 1080p 60Hz

If I select 60HZ, non-interlaced for Mon2 in the Display Adapter Properties from Advanced Display Settings in Windows, the resolution for Mon1 changes to 1080p and 2560x1440 is no longer even listed in the available resolutions. I tried creating resolutions for both monitors in CRU but selecting a custom resolution on Mon2 creates the same situation on Mon1; likewise for Mon1.

What I want is Mon1 at 1440p and Mon2 at 1080p.

Is this scenario possible?

TIA
