Novice Questions

I'm an HDTV novice, so excuse my stupid questions.

I just replaced my 12 year old 27" Sony with a 34XBR960. I've read a lot about this set and expected it to have an incredible picture out of the box. I have digitial cable (Comcast) with an HD set-top box, and the digital stations do look noticably better, but standard def stations looked better on my old Sony than on this TV. Also, while the digital stations look better, they don't look as great as I expected. Is this because the digitial stations aren't necessarily broadcasting in HD?

What do I need to do to improve my picture quality?

Another dumb question - does the TV automatically detect the resolution of the source (480i/480p/720p/1080i) and display the best picture accordingly?

:confused:

No such thing as a dumb question :)

What make and model # is the Comcast STB?
Motorola 6200HD?

Yes.

Yes, the STB is a HD Motorola DCT6200.

I split the cable and have it coming directly into the TV and from the cable box to the TV via component connections. The picture from the STB is actually a little better than the one using the TV's tuner.

Are you having any problems operatiing the twin view or PIP. I have the same set and split the icoming comcast signal to the Motorola STB and into the cable input on the XBR. Still experiencing problems with the set-up for PIP.
Any advice would be appreciated.

Quite often a cable box would have been in use by a previous customer that returned the box. In those cases we find that the settings for the cable box have been altered by the previous user of the box. Some cable boxes will allow the output on the component connections to be set for 480i or 480p as well as 720p and 1080i. I used to have a Toshiba wide screen TV that had color stream component inputs that would take a 480i input only, so my DVD player had to be set to 480i rather than the progressive scan.


If this happened to your cable box it would cause the symptoms you describe. The HD picture would only be marginally better than SD material. Worth looking into.

As far as the PIP setup goes, most HDTVs will only allow HD sources to be displayed in the primary display window. The PIP window will only display SD sources, whereas the main window (the one with the audio) will allow both HD and SD sources. Also most HDTVs will not allow the swap function except between two SD sources.

If you have split the incoming cable, make sure you use a good quality splitter of at least 1 gig. The lower priced , cheapo splitters may ramp up to 900mhz but for digital-HDTV, you need higher.
Also, splitting will lose 3-5db per connection, so better quality is needed.
How do things look with a straight cable feed to the tv?

i too can relate to all these responses--the fix?-get a signal booster from radio shack--the 4 way is just 50 bucks and made a world of difference--we all use splitters--and at a cost-i was using 2 high quality 4 way splitters--i went HDTV in 2 rooms--cable guy said tv in puter room was 14 dbs down in strength--got the radio shack and jaw literally dropped on std stns--you DO lose pic quality using splitters--and ive tried others but radio shack really did the deed-its the best--got one off ebay (another brand)that made the picture worse!-try one--youll NEVER return it--the grain and slight snowy background is gone!

I had ISF calibration and he turned down the sharp to 5 and turned off Edge Enhancement.

Ooops...not for me! I tried the Radio Shack Signal Booster, and the results ranged anywhere from unimproved to definetly degraded.

They took the return without complaint.

Now I'm back to the 4-way splitter I was using. I've no idea why the booster didn't work. Any one?

Try using a "Just mode" for standard broadcast stations and trying to adjust some of the features on the TV set up menu for noise reduction etc if you have them. I believe an HDMI interface cable would help automatically detect the correct settings if utilized and would provide a better picture but at approx $100.00 a pair not sure if you think it is worth it...
