Screen darkening with light objects
One other thing I have noticed with my new TV is when viewing pictures, it
looks fine. But, if a light image comes into the picture, the whole screen seems to darken down a touch. Not a lot, but if you're watching a moving picture where something light is coming in and out of the picture fast (Like someone walking down a corridor), the whole screen has a slight flickering effect. Also, pressing the TV info button, to get the information banner up, the sane thing happens. Like I said, it's very slight, but once you notice it, it's annoying! Any ideas? It's something I can easily live with, but I've not seen it on previous TV's I've had in the past! Matthew Long |

LCD panels react slowly to rapid changes in images and they have poor contrast ratio for moving images, so they shift the center contrast point as scene content changes. LCD panels are not the best for watching tv. |

Matthew Long It sounds like it could be poor EHT regulation, which is rather common, particularly on lower end CRT TVs. It's not a fault as such, more a sloppy design. You'll probably have to live with it. Dave |

Matthew Long it really sounds like you're not happy with this. its time to see if you can swap/refund or upgrade it to something better. do they have one on display somewhere so you can see how it runs? |
