Basic setup Sky+ set on RGB, scart into 32" Matsui LCD TV Xbox 360 hdmi into same TV.
In an attempt to improve my picture quality before I decide to shell out for SKYHD I had a play around with the brightness, Contrast, Sharpness etc and realised I didnt really know what I was doing.
How exactly do I go about setting these to acheive best quality, on a DVD once I had a THX (I think) configurator, that took me through step by step each adjustment, i.e lower the brightness right down, then slowly bring it up untill a logo appears, then onto contrast etc.
I also have options to turn LTI and DCI on or off, what are these and what do they do?
DCI is "Dynamic Colour Improvement" which tries to adjust your picture to optimum automatically - sometimes it works well sometimes it doesn't
LCI is "Luminance Transient Improvement" which basically tries to improve the sharpness of pictures especially where there are sudden differences in brightness eg a black and white stripe.
Basically set up everything with these set to off then try them to see if you like the difference they make.
All old televisions (even valve ones) had a form of LCI built in because the bandwidth of TV signals was limited, it is comparable to turning up the treble on a medium-wave radio station to make it sound less muffled.
Viewing is very subjective, most people have contrast and especially colour set a lot higher than optimum reality values. You tend to accept what you regularly see as the norm as the brain adapts.
I have found DCI useful on films that have been made particularly dark (eg many modern horrer movies).
