> I'm unclear on where you got 104x78.

    Module  Res     Size
    P1.923  104*78  200*150

I went ahead and counted... 128x96 (12,288 LEDs)

It's just bad pictures and errant info.

Here's a better link: https://www.aliexpress.com/item/32965783207.html

It's 160x120, as I mentioned for a 200x150mm P1.25 led module. You just divide the width/height by the pitch to see the number of dots.

As far as I can tell, 1.25mm is the smallest pitch available for these modules.

lol, I marked every tenth led manually and counted twice - the number is correct, the marketplace is wrong.

You counted dots on a picture of something other than a "200mmx150mm P1.25 led module". Pitch is the distance between the center of each LED.

1.25mm x 160 = 200mm

1.25mm x 120 = 150mm
