How can I create a virtually lower and letterboxed resolution?

dj flag

I have a screen which only accepts the 1920x1080 mode (others are garbled and adding custom modes does not work either). However, the screen has a centered viewable area of 1440x1080. That means the external screen crops the left and right.

I would like to make the resolution of that screen virtually smaller while keeping the same display mode, effectively adding letterboxes on the left and right. I have been trying some things with xrandr but I always ended up scaling the output which is not what I want.

Example for the result I would like to achieve

Thanks a lot in advance!

Edit: I'm using Ubuntu 21.04

tl;dr: I would like to create a virtual screen of 1440x1080 and display it on an external display which is fixed to mode 1920x1080.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
