My FM3 was actually a very pleasant surprise compared to the QC. Black levels and contrast are good, colours look good (not that it's super colourful
) and it's decently sharp. The QC screen was very washed out, the darkest colour on there was a fairly light gray and it was sometimes very hard to distinguish between orange and yellow, or blue and purple for example. I had pretty bad blue light bleed and the pixel density was pretty low. You could basically count the pixels on screen.
Cortex control finally looked like how I imagine the QC screen should be. It looks really good, I think.
