From what I understand, it doesn't take much heat to generate a whole lot of noise. I am not certain what the "sweet spot" temperature is but this is what has been partly to blame as to why Phase has not improved on their LCD.

Heat?
Uh I'm not a scientist but I don't know about that one. I've shot the Canons, the Nikons and even the Phase in 105F heat all day long and didn't see any real difference in noise.
How can a 3/4" more lcd make that much of a difference.
Anyway, I don't really think it's the lcd any more or less than the previews the backs generate.
In fact I just got this strange Phase extreme newsletter where they freeze it, bake it, and drive a truck over it. so a larger lcd will cause noise? I don't know about that.
It's funny though that this conversation has been going on for years and the lcd's look pretty much the same.
Meidum format, or any professional capture device is never going to escape this issue, because the real benfiit of digial capture is knowing you have the shot.
It's also cost related. You just can't say you spent 40 grand on a back and then show a client that lcd, it's like showing them those little 2 bedroom 1 bath houses in Venice, Ca, next to a Liquor store and telling them they cost 1.2 million. They just shake their head in disbelief.
I have this little hv20 Canon camcorder with a Letus on the front and use Nikon lenses. The little flip out lcd is not what I would call beautiful, but it's so detalied that you can shoot a 50 1.2 wide open and focus on the eyes . . . either eye.
At one point, Fuji had something like that, with that medium format back they made and never sold to anyone. How hard is it do let it flip out and not cause heat, it that really is the issue.
The thing is it's eventually all about the client. Phase's client, miy client, my client's client.
If a client (customer) keeps asking for something and it never comes then they move on.
We all have ways around the lcd, sometimes using the Canon or Nikon as an electronic Polaroid, sometimes using a powerbook or that 250 lb cart o' rocks, but we're in the business of delivering, so we deliver.
Now how do you think the Red would have been received if their lcd was smaller than the hv20?
