Futaba 10C color screen differences

[AlvaSpeed]

Just out of curiosity.Color screens.
I have a 10CH and my screen is blueish
My friends are greenish (if that is the correct word)
My graphs look sharper than theirs.
Is mine a newer version?

I asked the service folks at Hobbico/Futaba about this. Here is their answer:

Hi Bill,

I checked three we have here and they are all the same.

I think what he is referring to is if you set the contrast around 15 there is a slight bluish tint to the screen, but if you turn it down to around 5 or below, it is slightly green. That might be why his friends are not as sharp as his, they have their contrast turned down more than he does.

Have a good weekend, Krysta
