Hi def dlp (?) picture distorted

A friend's new hi definition TV, I think he said it's a dlp, has
pretty serious distortion. Where the image kind of waves as the
picture pans, with most distortion at the edges. He asked the store
where he bought it about this and was told that it was because he
needs to get hi definition service from his cable or satellite
provider; that the distortion comes from the hi def tv compensating
for the lack of hi def signal and will not work properly without
that.

Any truth to this?

Thanks.

None whatsoever.

I know of no high definition TV, monitor, etc. that's not capable of
properly displaying a standard definition signal.

He should check all settings to make sure the TV is set to display a
**480i** signal. Otherwise, get very insistent with the merchant
about a replacement.

It sounds to me like he has the picture set in stretch mode.

Perhaps, but "waves as the picture pans" isn't really consistent with
that.

Note to OP; a picture of what you're describing would be helpful.

In a word Warranty. If it is a new TV let them send out their service
person.

Could be. I'd want to know the brand and model.

But any digital tv upconverting an NTSC signal is doing some work, and
it's not always their best trick. I was watching a 60" plasma set up
at work with only NTSC signal (don't ask), and yeah, depending on the
program, you can get a little seasick watching fast motion, even the
pan for a football game, and the runner moving.

Where does he live? Can't he find some over the air hi-def signals to
watch? Not only would it help diagnose the problem, it would look
better!

No.

He's got his TV setup in one of the stretch modes that distorts the outer
edges of an SD picture to widen it out to wide screen mode. The other
stretch mode widens the whole picture making everything in it wider.
Personally I can't stand either of these for SD. To be seeing a true SD
picture, he would have black/gray/whatever bars on both sides of a
centered picture on the screen. The wavy motion on the edges he is seeing
is due to the distortion of the edges created by the stretch mode. The
other stretch mode distorts the picture all the way across and will do
away with the affect he's seeing. My dumbass SIL watches SD TV this way
thinking sees watching HDTV. An SD picture on any wide screen TV should
only occupy the center portion of the screen if you want to maintain the
proper aspect ratio.

It is with using the morphed (for lack of remembering what my TV calls it)
outer edge stretch mode where just the outer edges of the SD picture is
stretched way out of proportion.

Actually it sounds exactly like stretch mode,
just not a linear stretch. I am referring to
the type that keeps the center the same but
stretches the edges.

The truth is he is watching regular 4:3 TV on his widescreen. Newer
TVs, I have noticed rather than have a simple distorted squat, employ
a new algorhithm to insure that the center of the image is less
distorted than the edges. Ask him to watch the commercials, or NBC
Nightly News if it's available in HD. If he has a true HD signal,
there will be times when a 4:3 image exists in the center of the
screen. If he does not see this, then his TV is doing the fancy
stretch.

As for calling people dumbasses, it's a new technology. If he refuses
your help, if he thinks that the mere fact that he's dropped a dime
means he's automatically the hot ****, the correct term is
belligerent.

But if he's willing to try OTA-HD for the real stuff, he is slick.
Tell him to look up his local stations on Wikipedia to find their
digital channel info, put his old rabbit ears on his new set, and get
busy on the cheap.
