Pinkardvark - you are basuically wrong.
Your LCD is nowhere near 5000-1, it may claim it but its nowhere near it.
It is a combination of LCD tech + the cheap scaler. I am fussey beyond belief. I will be spending more on a scaler than you have on your screen to put it into perspective. I have tried a Lumagen, iscan + crystalio scaler and i am going for a cryastalio (maybe 2) scaler to get a better dvd + sky picture.
Lets clear a few things up here. The Sammy is one of the worst LCD screens around on SD material (im talking major brands not supermarket specials) The best screens are the Sony + Philips - both destroy the Samsung on SD material, both are destroyed by a Panasonic or Pioneer plasma on SD + HD. There is no comparison. Nobody who has tested them side by side has ever picked the LCD as being better (im talking mag reviews, ISF calibrator reviews + mine and many of my HC friends) If cost where no object nobody would pick a LCD over a plasma.
Simply put LCD's can not do blacks, have a worse contrast ratio, smear, have higher response time + generally FRC all sources. These are simple facts, this is before we get to the terrible scalers in the lcd's. I guarantee you that if you picked up a cheap £300 Lumagen Vision scaler and ran Sky+ into that and then to your screen the jump in quality would blow you away.
Im not knocking LCD (im getting one for the bedroom - i can accept the drop in quality there) and i am the first to say that a CRT projector blows my plasma away. If SED is all its cracked up to be my plasma will go and a SED will be on the wall. Price is not an issue for my main screen (daylight viewing is before Jes sells me a barco
) but quality of picture is and LCD's can not touch a plasma. Having personally seen a ED Panny PW7 42" next to the 40" Samsung HD screen the owner and i both picked the Panny on both HD + SD - yes HD material looked better on a non HD screen than on a full HD screen. The sammy went back.
Sky+ can look stunning on a good HD screen, even the lowest quality chanels look fine on mine, certinally not as good as a movie chanel or bbc1 or C4 but the worst on mine look as good as the best on any LCD ive tried. Thats partially the limitations of LCD but mainly the cheap and frankly rubbish scalers used in most of them.
