4k natively supported on my 1440p monitor?

[Heflo]

Hi all

 

Today I recieved my new and shiny Gigabyte AD27QD. This is my first high end monitor, so far I only had 1080p 60Hz monitors.

When I entered GeForce Experience, I noticed it recommends optimizing all the games to 4k resolution, which was odd, since my monitor is 1440p.

I then went to windows display configurations to find that although the 1440p option is labeled as the recommended one, I can increase it to 2160p.

I currently run dual monitors with an RTX 2070, the AD27QD connected via display port and a generic cheap 1080p dell monitor by HDMI.

 

What is the reason behind this?

I believe it is trying to run them super sampled. It renders the game at a higher resolution then downsamples it to 1440p. It gives you really nice antialiasing.
