This is a brand new monitor i bought some months ago (late 2019) and the cost was much bigger than 5 dollars. In fact it was the most expensive VA monitor at this resolution (i avoid IPS because i actually want to be able to see dark colors and contrast and every single IPS monitor i've used, regardless of resolution, is garbage when it comes to that with the awful backlight glow), it has a ton of inputs at the back, relatively fast response time (for VA), etc. It is one of the best monitors i ever had.
The resolution was something i explicitly opted for, partly because at the time i had an APU-based system that i wanted to game on and i didn't want the blurry mess that a higher resolution would have and partly because 1366x768 on a monitor (as opposed to laptop) makes for very sharp icons, fonts (after you disable antialiasing) for everything (as opposed to using a hidpi monitor where some apps look crisp and others look either too tiny or blurred from scaling). Also as a (very high) bonus, it looks great when playing older games that often use 1024x768 as a resolution since i have 1:1 mapping there.
Finally 1366x768 is currently by far the most common resolution on PCs (mainly thanks to laptops, but desktops use it too - see mine) according to statcounter and the second most common on gaming PCs according to Steam, so it isn't something you'd only find in obscure old PCs, it is as mainstream as it gets.
