Whats the best way to set up my Explorer 4200hd with my Samsung crt hdtv?? My tv is compatible with 480p and 1080i. The cable box has 4 settings for picture output. It has Fixed, pass through, upconvert1 and up convert 2. Up convert 1 up converts to 480p OR 1080i, the up convert 2 gives 480p and 720p. Im using Upcionvert1 since thats the resolutions that work with my tv. Would using the pass though be better maybe would it get rid of the extra video processing that 75% of the time I don't need?? My Tv already up converts all SD to 480p, but im not sure what its doing on 1080i stuff? Its a Samsung tsl2795hf 27in crt. Im having trouble finding much info about this tv, anyone have any specs for it?? I got it from my brother a year ago when he moved and bought a bigger lcd and he didn't have the manual or anything.
thanks

OK, I'm in Australia where things are a bit different but I've got a Loewe high def LCD TV and both my separate free to air digital tuner and my DVD player offer rescaling from standard def PAL (576i) to 720p and 1080i. My TV has a native resolution of 1366 x 768 so if I allow my source to upscale things to 720p The TV is still going to have to do another rescale from 720 to 768 anyway before it can display the picture.What I found was that I'm better going with straight standard def output from both the tuner and the DVD and letting the TV do all of the scaling in a single hit. I definitely get better results with only 1 scaling operation than I do when some scaling occurs in the source component and some in the TV.
I think it would be a much more interesting comparison if my sources could rescale to the TVs standard definition of 1366 x 768 so there was only one rescaling operation and the choice became whether to do that at source or at display. Then the question would depend simply on which device did the best rescaling.
Since your TV is 1080i and your cable box can output 1080i, that's the position you're in. The answer is simply going to depend on which of the 2 can do the best conversion from 480i to 1080i. The only answer that makes sense is to try it both ways and see which you prefer.

Another thing, since crt doesnt have a "native resolution" like an LCD shouldnt the scaling have less of an effect on the picture quality?
let you set your specific scaling requirement (i.e., 768). But some of them are pricey!Terry
I know there are scalers and upconverters around but the TV does a damn good job upscaling standard definition inputs. I really can't see it as cost effective to add another box to my mix.I was merely commenting on the issue of letting a source device do the upscaling vs the display doing it, and the associated problem of whether or not letting the source upscale will result in 2 upscale operations with the second one being required at the display end.
To summarise, I was saying that I think it's always better to run with only one upscaling process rather than letting the source and the display do some upscaling each. When you have the option of the display doing it all, or the source doing it all, it simply boils down to which one does it better.

awareness of watching out for "2 upscale operations".I'm trying to decide between a reasonably priced 720p plasma and a much more expensive 1080p plasma or LCD. I didn't really think about the fact that the plasma will be scaling everything, even native 720p HD input, because its a 1366x768 display. If I use an upconverting DVD player (e.g., Oppo 971) to upconvert DVDs, I'll end up with 2 scaling operations. Not good, as you pointed out.

Im not sure what kinda of scaling my tv does. its an older model Samsung tsl2795hf crt hdtv. It upsamples all SD to 480p and will display 1080i. I dont have the model or any specs for this tv so i really dont know much about it. i got it for free from my brother when he got a new LCD tv. I cant seem to find much about it onnline either. Anyone know anything about this model???
Hi Frank.I wish I could be more help but I've generally found that the easiest way to set these things up is to keep trying it with different settings and see what works best. Not a very elegant solution to be sure, but it works. The nice thing is that there's no way to do any damage. Everything's reversable so if something looks terrible, just reset everything to default.
