Anyone with a nVidia GPU laptop? A question about custom resolutions.

According to this guide

http://screenarchery.wikia.com/wiki/Downsampling_%E2%80%93_A_full_guide_to_achieve_3840x2160_resolution_%E2%80%93_NVIDIA_only

you can make your lower resolution monitor output a higher resolution image with downsampling.

What I'm particularly interested in is to be able to use say 1440p on a 1080p monitor, or 1080p on a 720p monitor. Not only for games but for some desktop work as well. I know the text is going to look blurry, but more space seems to be worth it.

Edit: sorry, the question is, can you confirm you can do that and how is the experience?

You can get a slightly higher resolution on most monitors due to extra pixels but it doesn't look any better. I've tried it on my Asus 1080P monitor. You can run at a "fake" 1440P but it will look like crap. Though you can kind of get a feel for what it would be like on the desktop.
