What determines how Standard Def will look on an LCD?

I have a Samsung 720p 42" tv and standard def looks pretty bad. I had read that tends to be the case with Samsung but it didn't really matter to me I don't watch much SD. But, I then got my parents two Sharp Aquos 32" 720p and their SD looks real good and so does their HD. So, I am helping a friend pick out a 47" to 50" LCD and I am trying to determine what product specs I should pay attention to that would help me know the SD picture would look good?

Thanks for your help.

The biggest factor in the quality of the SD will be the source not necessarily the TV. DVDs will give you the benchmark for what the TV will do as far as SD is concerned. Cable and satellite SD tends to look pretty bad. Having a HD receiver or cable box will help.

The scaling chip used by the TV is just as important as the source I think since most people get solid SD signals these days from cable/sat/even a antenna... If your set looks bad when viewing DVDs try out a upscaling dvd player.

I would say having components with component video capability to run then thru vs using s video or standard RCA's because even on my Hitachi 50 inch projection i could tell the differnce in hookng up anything from good to better for example standard Rca's to s-video, and so forth on so if ure gona have SD then im thinking right before hdmi connection is component and from what i have learned from guys here component is really neck and neck with hdmi but most of ure sources like dvd players and so forth if not hd will and should at least have component capability unless older than a 2000 model or so

Not really, and actually backwards.

As rbink advised, DVD will provide the most reliable benchmark for how well a TV can process and display a SD signal.

Right behind that would be OTA (antenna) of network and even most local programs, since these are typically not compressed and provide a relatively high quality signal.

In the case of cable or sat, it depends on the specific provider as well as the channel - many are heavily compressed, leading to poor quality pictures on HDTVs because upscaling will amplify the compression artifacts.

I don't think Samsung is suspect for SD reproduction. I have a Samsung (though 1020p) and it is excellent for SD. I have no complaints. Every once in a while SD looks crappy. I blame that on the source of SD, not my TV suddenly getting lazy.;)

The 32 inch looked better than the 42 inch because the smaller the size the better sd will look.
