Please help achieve HDTV without HDMI...
Our daughter bought a condo in a deal that included appliances, etc., of
which one was an LCD television set by LG: model DU-42LZ30. Online there are excellent reviews for this ~4 year old product, but the published specifications confirm that it lacks an HDMI input. The off-air HDTV tuner is excellent, and for that we need no help. However, she has a DVR "Box" from Time Warner that has video, component video, and HDMI outputs. The LG television set has the following inputs: RS232 - DB-9 Component - 3 RCAs DVI - 24 pin S-Video - 4-pin DIN At the moment she has the TW Box connected via component video, but the image is definitely *NOT* HDTV-quality. What can we do to improve the video? Thanks, Lon |

No, you get a set of component cables. They will be red, blue, and green (RGB), and may also have the audio cables included which are red and white. you plug those 5 cables into the component and audio output of the TW box and configure the TW box outputs to match your TV. You can use 2 sets of composite cables (y,r,w) to test the component output, but it will not be as good as using real component cables (RGB+ RW for audio). Download the manual for your TV or pretty much any TV, and it will show you how to connect it. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

They are, so presumably it is, though I don't know the difference. Component video (three plugs; red, green, and blue) offers excellent quality that is more or less indistinguishable from a digital connection (HDMI or DVI). Composite video (one plug; yellow)'s quality is greatly inferior. If the settop box is high definition-capable, it likely has component jacks. The television also likely has component jacks. Get a component cable, either a five-plug type (with red and white cables for the audio jacks), or a three-plus type (and use your existing red and white cables). Purchase an HDMI:DVI adapter? If the settop box is high-definition-capable, it also likely has DVI output. Yes, a DVI-to-HDMI adapter is an alternative to component video; of course, you'll need a DVI cable, and you will again reuse the existing red and white cables. I personally use Monoprice.com for cables and adapters that are much, much, much cheaper than from the local Best Buy. -- URL:http://www.pobox.com/~ylee/ PERTH ---- * |

Thanks Yes, you can buy a cable that has an HDMI connection to your STB and a DVI connection to your TV, that will give you HD picture but no sound, so you need to add simple coax for sound separately. I "think" there may be some special adapters that will give you sound over DVI, but I've not seen them, and it's likely that you have to have something special on the TV side for that to work. BUT, if those component connection have good component cables, you should already be getting HD. I have one HD DVR connected to my 1080p set via HDMI and the other HD DVR connected via component cables, and I can't tell any difference in the picture quality when viewing 1080i content. |

The LG television set has the following inputs: RS232 - DB-9 Component - 3 RCAs DVI - 24 pin S-Video - 4-pin DIN The DB-9 isn't for video. However, there's also a DB-15 for VGA-style video. 2 sets of component inputs (red/blue/green) with analog audio (red/white), 2 composite (yellow) or S-Video with analog audio and 2 DVI inputs. There are also optical audio inputs associated with at least 1 DVI and 1 component input. I didn't read far enough to determine all the possibilities. At the moment she has the TW Box connected via component video, but the image is definitely *NOT* HDTV-quality. What can we do to improve the video? Component (not composite or S-Video) should give you HD very similar to what you see off-air. It's possible the cable STB is reducing the resolution on the component output. In any case, I recommend trying an HDMI to DVI cable. Don't pay a lot for it. You'll find good prices he http://www.monoprice.com/products/su...s_id=10231 04 See p. 14 of the manual for various STB connection options. You can also connect the cable directly to the TV, bypassing the STB, and scan for unencrypted cable channels. The manual isn't clear about whether the TV will tune digital cable but If it does you'll probably just find the ones you're already getting with an antenna plus a few others you don't care about (which is why they're not encrypted).

Del Mibbler Good overview, Del, but it seems like a lot for a display that is not 'true hd' (only 720). |

Note that the CNET review http://reviews.cnet.com/flat-panel-t...tml#cnetReview says, in part, "Resolution measured much higher with the DVI input than with either of the component-video inputs; the component-video input rolls off some of the high-frequency video resolution from a 720p signal. We recommend that you use the DVI input for your HDTV connection." So you might do better with an HDMI-DVI cable, as others have already suggested. |

Constructive/gratifying responses -- THANK YOU.
She'll pick up an HDMIDVI cable today, which for a few dollars should optimize the situation. |

That doesn't mean it isn't hd! 720 is too low for HD in Europe. 720 is only Extended density, not High density. That's interesting because in the USA, Enhanced Definition TV is what used to simply be called Progressive Scan, which is 480p resolution. USA High Definition TV is 720p, 1080i, or 1080p. |

Component is just as good, at least pretty close to HDMI!!! Both support
1080P HD formats. Component is Analog and HDMI is Digital. Are you sure it's a Component connection and not a Composite connection? Component is using a RED, Green, and Blue RCA type plug for Video and a Red & White for Stereo Audio. Composite uses a Yellow RCA type plug for Video and a Red and White RCA plug for Stereo Audio. Component you get HD, Composite is SD ONLY!!! Doesn't matter if your source is HD if it's going though a SD cable, it'll be SD on the HDTV. Now DVI is HDMI with without the built in Audio. HDMI supports both Digital HD Video, and Digital Multichannel Audio. DVI ONLY supports Digital HD Video. The good news is that you can get a cheap HDMI to DVI cable. So it's HDMI on one end to go out of your HD Cable box(It is HD right?) and the other DVI end can then plugs into the HDTV. This will give you Digital HD Video to your HDTV. Of course you need sound also, so a normal set of RCA cables RED & White from the cable Box to your HDTV to get the Stereo Audio out of the HDTV's built in speakers. OR get a new HDTV!!!!

The spec was last revised five years ago, and defines 720p and 1080i, but not 1080p. *Some* devices will output 1080p on component, but most do not. Most BD players and upconverting DVD players will not put out 1080p on component video outputs. |
