I did a few more tests tonight...I think a Blu-ray looks better at 480p, but mkv's seem to benefit from 720p (and these are 720p mkv's). Maybe the full bitrate 480p is the sweet spot. I don't notice more detail at 720p...just a bit more noise, and seemingly less contrast. These aren't huge differences, just slight.

There is always someone with a bigger screen around on this forum. Laughing

Mine is made of counter top laminate and is 2.5m wide. I win until the next guy with a 708/Cine7 and a bigger screen posts. Wink

You win, but im much brighter at 2.27m wide, although i bet mine is taller than yours Wink

I ran the XG at 1280x768p @75Hz for a while on 3D, but ended up changing to 1366x768p @72 Hz instead.

For standard 2D content, it was all done at 1920x1080i @60Hz, which most certainly looked nicer than using 1366x768p @72Hz.

On the 9PG, i used 1920x1080i @60Hz for bluray and all movies from a PC, but DVDs from the bluray player looked better at 576p @50Hz, the odd US region DVD i have looked very coarse in 480p @60Hz, so i ran those in 1080i @60Hz ( DVDs in a 576p 50Hz format would display at 50Hz in 1080i and i couldnt change that. )

On the Cine 9 i run everything at 1920x1080p @60Hz, and its quite fine.

I'm not observing in terms of scrutinizing the screen for detail...I'm just observing an overall better picture.

I have an embarrassing confession to make. I can't convert from inches to meters properly. Embarassed 2.08m is my screen width. Crying or Very sad

You know, in a way I'm glad my Cine7 takes about 15-20mins for its convergence to settle down. Since I can't tweak anything until it warms up sufficiently, that gross error distracts my mind early enough from other anomalies that by the time I could do something about it, I don't care anymore because the mis-convergence is gone and I've moved on to enjoying the flick instead of the picture I'm looking at.

Cant wait... PS I think im coming up to Gold Coast over the Chrissy break and need to pop in to see a bloke at Wynum to pick up a 708s i bought months ago Smile Once i got dates we'll tee it up. . .

I mucked around playing my blurays @ 480i/p and 576p then watched a movie at 1080i and found myself switching back to 720P so far 720P is giving me the best picture... and i really think im going to stop there with it... i kinda over it as the gains are minimal either way.... so back to movies for me for a couple more weeks till my marquee parts get here then it all starts again!!!! lol

Isn't a Cine 7 with fresh tubes supposed really sharp? EM level sharp? (untill 2000-3000 hours).

On my 808 1080i is definitely nicer than 720P! 480/576P isn't even close and i get massive scanlines.

I'm the next guy with a 2,6m screen and a Graphics 801s.
I drive it over PC (Powerstrip ATI GPU) @ 1080i 40,3Hz.
My scanlines are visible on each CRT and on the screen.
