Imagine a checkerboard, black and white squares alternating.

Frame 1, you render the black squares
Frame 2, you render the white squares

To make a full picture, take the rendered squares, interpolate the non rendered squares using the rendered squares and info from the previous frame when possible.

So basically you render 1920x2160 or 3840x1080 depending on how you look at it. Since the squares are offset each line it's better than interlaced rendering yet still exactly half the number of pixels of 3840x2160.

Yeah i was initially confused because 4 times 1920x1080 does not equal 3840x2160 with basic math. I found out that the reason they say "4x 1080p = 4k" is based off pixel count not resolution i.e 2mil for 1080p and 8mil for 4k witch is REALLY FUCKING CONFUSING.

So when they say checkerboard 4k upscale is using 4 1920x1080 frames to equal 3840x2160 i was a bit confused...when in reality they mean pixels...Yea fuck this shit, im out.

1920(horizontal pixels) times 1080(vertical) = 2,073,600 pixels Full HD
3840(horizontal) times 2160(vertical) = 8,294,400 pixels 4k

"4K" is double the resolution of 1080P but because of how rectangles work(length times width), it internally contains 4 times the amount of pixels. Also there's alot of confusion about the term 4K because it refers to the horizontal resolution, where 1080P referred to the vertical. Not sure why they did this, probably for marketing TVs and it being easier to say than 2160P or Ultra High Definition.
