LCD HDTV clearer picture?




raian48


Recently bought a 42" LG LCD HDTV. Aside from purchasing a digital cable box, is there anyway to improve picture quality (thicker insulated coaxial, using an HDMI cable instead, etc)?


Answer
Changing your cable (insulation, etc.) will do nothing. What you're really after is real HD images rather than analog or standard-def digital. Here are 5 things you need on a cable or satellite system to see real HD:

1. An HD television set.
2. An HD cable or satellite receiver.
3. A subscription to the companyâs HD channel package.
4. An HDMI cable (preferred) to connect the box to the TV, or at least a set of 5 component cables (red-blue-green video plus red-white audio).
5. You need to be watching a program thatâs actually being broadcast in HD, on an HD channel. (Some content on HD channels is actually standard-def.)

If any one of the above 5 items are missing on a cable or satellite system--no HD picture.

If you have a very good over-the-air antenna, all you need for HD reception is #1 and #5 above.

Note in the above discussion that âHDâ and âdigitalâ are not the same thing. For example, all satellite channels are digital, but many or most of them are stanard-def, not HD.

(There is actually another way to get HD channels on a cable system with no box, but it requires a 3rd tuner in the TVâQAMâand it requires QAM channels to be present on the cable system, which is not guaranteed. I only mention this option to make the answer fully complete, but in reality, QAM channels cannot be relied upon in all areas or indefinitely in any area.)

A 46-inch LCD HDTV without upconversion and connected via S-video...what'll be the picture quality on the tv?

Answer
I used to install cable/satellite and people who were getting HD programming installed would sometimes say the HD channels weren't clear enough. After 5 years of installing, my opinion is beauty is in the eye of the beholder. But coming from an ex-installer, I wouldn't brag that I had a tv connected through S-video. About the only difference you would see between that and a cable plugged directly from the wall is going to be the brightness of colors. This can give a false impression of a "good" picture. While S-video will definitely give brighter colors, your picture may still be distorted because of the simple fact that you have a non-hd picture being displayed on a HDTV. Trust me, you lose picture quality viewing non-HD channels on a HDTV because the picture has to be stretched more.
