You can try it with your monitor too: http://engineerjs.com/wtf3.png. Make sure to download this image and show it in 1:1 zoom (pixel correctly). Not all Samsung monitors are affected.

 

I bought a Samsung U32H850UMU "professional" monitor. I noticed that the edges of the letters flicker when the background is dark. Then I noticed the flickering is very heavy and unacceptable with some patterns (see test image above). It does it with my desktop computer, my MacBook, with every setting, every color depth (16, 24, 32), every possible frequency (60Hz, 30Hz), HDMI and DisplayPort too. It is a design fault clearly.

 

This is what it looks like: https://photos.app.goo.gl/jaKwL4GnbXoUFpE58 (right hand side is GIMP showing the image linked above).

 

It must be some kind of compression or temporal dithering that only processes every other pixel and then changes parity with every frame.

 

Dear Samsung engineers: why did you do this? WHY?
