Within a couple of hours after getting my LC26GA4E I contacted Sharp via email regarding what I thought was a problem with the RGB Scart input. I sent them pictures and details of the fault which can be found: On this page I've tested numerous RGB sources now with the set and ALL OF THEM produce this problem. "composite" is fine, "DVI" is fine, it's just RGB. Composite looks better than RGB ***!! After just over a week, this is the official response from Sharps technical department: "We have checked our sample but cannot reproduce exactly the same effect. We feel that this is not a fault but caused by the combined digital processing of the DVD and LCD circuits. The number of levels that can be displayed are fixed and the resolution appears reduced when dealing with single colour/ no colour images. When image are processed digitally the levels or of brightness and colour are quantised to fixed levels when this applied to a apparently single colour or brightness level some areas are quantised up to one level and others are quantised down, on a plain background this can cause noticeable differences in brightness or colour especially when enhanced by boosting the signal levels in the dark areas by changing the brightness level. It is also important to realise that the brightness control does not change the brightness as in a CRT TV it's is more like a gamma control and works to an algorithm which works on specific picture areas depending on picture content. It is likely that the effect can only be seen via RGB mode because it is not subject to the low pass filtering applied to composite signal and the small variations in the background signal are thus not eliminated. Please understand that LCD / pixel based displays can only display a fixed number of levels and this type of effect is not unexpected. It is also worth pointing out that the number of levels are not evenly distributed and in dark areas there are less levels which means the difference between one brightness level and another is greater and as mentions before the brightness control will stretch or compress these differences making them more or less noticeable. Please adjust the levels for the best overall picture. We hope this explanation helps your understanding of the phenomena. I hope this helps." Please, anyone of you with a GA3 or GA4 LCD, hook up an RGB source and set the brightness of the set to "5" or "10" or something, then go watch the credits of a movie, or look at some blacks anywhere. Plug in your Xbox and look at the logo intro. I find it REALLY hard to believe that Sharp can pass off this as "not a fault" or in any way acceptable. Watching a widescreen movie while the black bars at the top and bottom of the screen and having a wee little dance is not much fun at all :-(. So, according to sharp I have 1 option, simply adjust the settings to where this problem doesn't become visible? ie, reduce the brightness of the set way below "0".... not a happy bunny.
