You add bright direct sun to any monitor and the brightness and your view of and from it will diminish, and you will surely get some level of a nice reflected
image of the big ball in the sky too if you are at the worst angle for your shot.
Cinetronic, TB-6, all of them. Sure they are "sunlight viewable" and I understand that the Cinetronic is all around exceptional and I will most likely own one in the future, once they are proven a bit more, (hey Chris, good to hear you are doing well and congrats on your monitor, it's been what, 15+ years since we've seen each other?) but no manufacturer will claim you can see the image as well in bright direct sun as you can when the screen is in the shade.
For that reason, no matter what monitor one uses, you will see the image better and brighter when it's shaded, and that's why I use one on my monitors
when outside and have direct sun hitting the monitor (and it's not windy).
I just figured after nearly 3 years with the Nebtek and using a home made sun shade, it was time to actually find one that is a bit more polished.
