  (Asked by: username_0 on 2019-01-22)
  
  I just bought a Feelworld MA7 and did some test yesterday regarding false colors.
  
  Here are my tests:
  
  1) video capture of the scene, together Final Cut Pro X's oscilloscope:

  We can see that although pink should be for totally black areas (IRE < 0), MA7's false Colors show pink even in areas holding information, like the left side of the t-shirt which, according to the oscilloscope (and according to our eyes), hold some luminance values.
  
  To push the test a little bit further, I used a lut which applies false colors onto clips in FCPX (<https://luts.iwltbap.com/false-color-lut/>). Here's the result with the corresponding scale (I think it's Atomos' scale):
  
  [![enter image description here](https://i.sstatic.net/s2CMK.jpg)](https://i.sstatic.net/s2CMK.jpg)
  
  In this case, the results are much more intuitive (and better corresponding to the oscilloscope): nowhere do we see dark purple (IRE < 0 on this scale).
  
  Why is that? And ultimately, can I trust the Feelworld MA7 field monitor to help me accurately expose my scenes?

  Such cheaper monitors often don't have enough power to calculate it correctly.
  Often they are just added as a sales pitch.
  I wouldn't totaly trust it, but you can take it as a rough estimate.
