Hi all, I have been reading these posts and have been forced to give my unbiased comparison between these two sets which i have owned each for two weeks before returning them. Rainbows: Sry guys but rainbows were very noticable to me on both sets but slightly worse on the samsung, This was very annoying even when you think you might be able to try and live with it. Dot dithering: Now this does not exist on the samsung set but is very bad on the toshiba. This is dot movement on dark patches which when the screen pans is very noticable as it goes to a rainbow type blur, this is a seperate effect from the rainbow effect. Good example is in Halo on the walls in dark corridors just walk or move around and believe me it sticks out like a saw thumb. Picture quality: On pc and digital connections the samsung wins easily due to the toshibas dot dithering on games (not desktop as this is stationary). But on all other connections the Toshiba wins outright because the samsung's rgb and component connections are appalling and present a weak composite like appearance which is very soft and washed out even in progressive. Samsung does benifit from the faroudja processing which produces better panning etc. Sound: Here i thought the toshiba was very good due to nice subwoofer whereas the samsung sounds very ordinary. Appearance: Both tvs look great although i think the samsung looks abit too futuristic and does not fit in with surroundings. The toshiba looks alot better than in the photos even though the stand is abit cheap but hey its free and looks great when all put together and is perfect in appearance for any room. Viewing angles: The toshiba has a very slight advantage on side viewing but a larger advantage on above and below. Opperation: Both have a good menu system. The toshiba has a quick input selection box which opens when you hold the av change button down where as the samsung you had to go into the menu, unless i missed something. Other notables: The samsungs screen seemed to have a problem with getting dark patches which when pushed lightly with something soft would dissappear with a cracking sound but when the tv is switched off they come back the next morning. Things that i think have proved true: Six segment colour wheels have less rainbow but introduce dot dithering and the othe way round for seven segment, which i preffered as dot dithering was so annoying. Faroudja processing does make a big improvement on picture quality. Dlp technology is amazing, so sharp and vibrant. Finally: I am amazed at the pq of DLP, so even though i am desperate to own another tv i would still rather wait for improvements in the colour wheel rather than going for a different display technology.TI SCR 126 segment colour wheel coming soon which uses a spiral/Archimedes approache to totally eliminate rainbows for ever . I hope ive helped some people out and not offended others, i have just tried to give an unbiased oppinion of my experiance. So tosh and sammie owners dont flame me before looking for the faults described first. Thx Tyn.
