Finally...Friday came round.
New 106inch white Grandview screen has been installed
I was actually surprised how big it looks on the wall.
Having never experienced a screen before I can only assume that the black border of the screen really helps set your mind about the size.
Unfortunately my projector is still been repaired.
So my repair place has lent me an entry level Sony. It's the light weight Sony EW7.
Only 720p , running it in standard 1500 lumens mode.
