In medical imaging, data are often acquired using anisotropic resolution. So a pixel (or voxel in 3D) can be an averaged signal sample originating from 2mm of tissue in one direction and 0.9mm in another direction.
If black and white or some other cases, but there are typically subpixels that can make things like sparse enough text stroke transitions get 3X horizontal resolution.
What is a little rectangle? Physical display pixels are separate RGB leds with a non-rectangular shape.
Many video formats use rectangular pixels. It's less common these days, but there were no squares on DVDs for example.
Even some VGA modes have non-square pixels, and these were used by many games and... Windows 9x splash screen.
BBC Micro in graphics mode 2 the pixel is a 2:1 rectangle. Other geometries for different modes. It's going back a bit, but very much living memory!

and it’s displayed with a completely different algorithm…
They're rectangles on my monitor.

Do the 3 separate sub pixels look like a photoshop pixel?
