1280*1024, strange resolution?

MonitorI just get something unbelievable! Or at least, very strange... :-|

Most of current screen resolution is 1280×1024 pixels, but this resolution has something strange and distorted the vision we have of pictures and text! I discover that by watching at photos in 1600×1200 and seeing black bands at the top and bottom of the screen.

Let's make a few divisions:

  • 640 / 480 = 1,33333
  • 800 / 600 = 1,33333
  • 1024 / 768 = 1,33333
  • 1280 / 1024 = 1,25
  • 1600 / 1200 = 1,33333
  • 2048 / 1536 = 1,33333

There's a kind of bug with the 1280×1024... :-o


On a 4/3 screen (not 16/9 obviously) the result of the division should be 4/3 = 1,33333!

Someone tells me the TFT screens build for 1280×1024 are in 5/4, so the following remarks are only true on CRT monitors.

To be sure, open your favorite drawing tool, and draw a nice 1000 pixels square. Now measure with a school ruler on the screen the so-called square: 22cm to 21cm. :!:

In any other standard resolution, the square in pixels are really visually square. But not in 1280×1084! :!:


The correct resolution should be 1280×960 to find the 4/3 = 1,33333 proportion.

If you are on a flat TFT screen, their interpolation is poor, so you must stay on their native resolution which appears to be correct in 5/4.

If you prefer, like me, the natural colors of a good old CRT, the resolution to adopt is 1280×960, even if it makes an adaptation time to use this new resolution! :-|
