I'm wondering, how does a 1600x900 monitor display a 720p resolution, which is 1280x720?

I know the old CRT monitors had no physical pixels, so they could show any resolution, but how does a LCD monitor, with physical pixels, adapt to showing an image with fewer pixels than it has and is there any loss of image quality in doing whatever it does to achieve that relative to a monitor with a 720p resolution?
 
Solution
It scales the image to 1600×900, usually with a simple algorithm like bilinear or bicubic scaling. There is a quality loss involved.
