Hi Saturday, welcome aboard.
Let get the screen out of the way first.
I was told the following, the darker the room (Full light control) the whiter the screen.
If you want to watch movies during the day, Grey is the choice.
I did a lot if research, please read the link from an Australian Screen Maker,
It explains a lot about gain, screen type.
I picked White and gain 1.1 which is for night time and perfect for me.http://ozts.com.au/gain.htm
That should help.
Now lets clear up the second bit, the settings on this forum start off without the use of Color correction filters and 1db attenuator, then about 1/2 way through we all went out and bought them.
So please note most of the settings except the early ones from ROne are with filters.
I saved all the settings in my user spots, i like the second last one from Jeremy.
Here it is, Yes i use it without a filter, i am using HDMI via the DVD Player.
I took off my filters and i am much happier, but thats just me.
Start with Powerful
Theatre /black bulb.
