I once worked out that I could spend a lot less on a projector if I just watched the resulting picture without my glasses on, therefore ridding the image of any 'chicken wire' effect!
Just a thought, wouldn't a 70" 16:9 with black bars be similar to a 56" 21:9 anyway?
And what happens to all that 14:9 and 16:9 tv that all the broadcasters have just geared up for. Black bars at the side again - ah well...progress I suppose
