[Tig] Fwd: Canon 4K monitor

Hey Robert,

For me the issue was evident when you had a small hot spot on the frame, it
would get dimmer and get the tone of the surrounding colors. I am talking
about looking at the monitor straight front on the color suite, not looking
sideways. In a starry sky, the stars would look dim and dull...

Also, an interesting artifact occurred when I was stabilizing a piece of
old film and some quick 1-2 pixel was happening. The image started
vibrating in brightness. Looks like the edge of black around the image was
creating a diffused shadow over the picture that was vibrating at the same
rate the thing edge was showing on and off.

Don-t get me wrong, I love the idea of having a reference monitor like the
Dolby where I can work on rec709 or P3 as well as feeding YUV, RGB or XYZ
color components and knowing that my color in general is pretty accurate,
but I was not expecting the silly artifacts at all.

Juan.
