Channel changing

post #1 of 4
Thread Starter 
Weird question, why on some lcd tvs does it take a while to change channels? Which brands are the worst at that (Pet peeve), which are the best?

Whenever a TV receives a non-native resolution, it has to scale/de-interlace the image before displaying it. For example, if you have a 1080p TV, and watch CBS, it has to deinterlace the 1080i signal. If you change the channel to Fox, it has to scale the 720p image to 1080p before displaying it.

I own a Sharp LCD and a Sony SXRD, it usually takes a few seconds to adjust to a different resolution. If you have a cable/satellite box, you can set it to output a specific resolution, which will be much quicker than letting the TV scale the resolution. The PQ usually not as good when the box does it though.

Thanks makes sense, one more question, does that mean all lcds will have this "problem" regardless of brand, ie sony, samsung, sharp?

I think there are some tuners that are just inherently slower to change channels than others, regardless of resolution of the channel. Unfortunately, I haven't used enough of them to give you any useful rank. It probably changes year to year within brands as well.
