Re: DVI vs Component cable-noticeable difference?

said by Kerrith See Profile :

I just bought the wrong DVI-Integrated Dual-Link cable from Radio Shack to connect between my 3250HD box and my HDTV. Instead of the three rows of pins and a spade shaped pin the Radio Shack cable has four extra shorter pins along side the spade. Ughh.

Question:

Is it worth searching for the correct DVI cable? In other words, is there a noticeable difference in picture/sound quality between a DVI cable and component (Y,PB,PR) cables?

My components:

Scientific Atlanta Explorer 3250HD
AT&T Series 2 TIVO
Sony STR-DE597 Stereo Receiver (5.1)
Toshiba DVD D-R4 Player-Recorder,
Sony Wega TV KV-32H500 (HDTV) w/PIP (Twin View)

Thanks,

Kerry
The cable you bought is a DVI-I cable, and the extra four pins are for carrying an analog signal (e.g. RGBHV). It would appear the port on your STB requires a DVI-D, or digital-only DVI cable.

As to which looks better is difficult to say. First, you have to take source (STB) and display (your HDTV) into consideration in how they handle and process the two transports and the signals that come across them. Then, you have to consider how your provider incorporates the video signal (signaling is above hatdware transport).

Depending on your display (analog or digital?), it might be worth keeping the STB-to-HDTV all digital.

Re: DVI vs Component cable-noticeable difference?

Hi GhostDoggy,

I've got it all working now.:) I'm so pleased with both the HDTV and the cable's scrambled and unscrambled channels, using an RGB cable and an S-Video cable, that I'm giving up on the DVI cable game.

FYI: Correction: Extra three pins. Also I surfed lots of online cable stores and could not find a pic of a DVI cable with the three spades and 24 pins.

Thanks,

Kerry
