DVD Upconverters??? Okay I have a Magnovox HDTV 1080i tv with no hdmi hookups. It just has the hdtv component hookups. They look great with the cable hd channels and the xbox, but i was wondering if i would benefit from the up converters. i bought one a couple months ago and returned it because my Tv detected it as still being 420p. so my question is... does the up converters have to use the HDMI cable to look better or are they still better than the progressive scan dvd player i have now??

When early up-converting DVD players came out, a few (Samsung, for example) would do up to 1080i over the R-G-B "component" cables. The movie industry leaned on everyone to put a stop to this and nowadays it is almost impossible to find anything that does upconverting to component. It's all HDMI so they can use the HDCP security to protect the signal.

OTOH, your TV is upconverting (but not as well) when it gets a 480 signal.

The movie industry claimed they blocked it to stop piracy, but most likely it was to prevent people from thinking "gee, I don't need Blu-ray or HD". After all, if some industrial site wants to make copies of a movie, I'm sure they can either dig into the electronic guts of an HD TV to hijack the signal or better yet, decode the Blurray signal itself.

Greetings jhays82,

Some DVD players can upconvert DVD signals to resolutions that match those of HDTVs, and send them to a compatible TV via a digital video connection. HDMI (High-Definition Media Interface) and DVI (Digital Visual Interface) both offer high-quality digital transmission of standard- and high-definition video signals. HDMI can also carry multichannel audio, and is backwards compatible with DVI (video only). So in other words, to receive the full benefit from an upconvert, you would want to hook it up with HDMI or DVI.

Thank You,

Agent Dort,

Can i get hd channels without an hdmi input. The TV is an HDTV


Sounds fishy to me----almost every provider uses a box that has either HDMI or Component outputs for HD--your set should if HD ready have a Component input for that also--if it only has the HDMI for that you may be out of luck. Check the owner manual to see if one of the Component inputs is HD or not.

HDTV cable hookup for HD component video


High Def (720p, 1080i) requires either HDMI or component video cable connections. This image shows how to connect using component video/audio. The RCA cables are green, blue, red for video and white and red for audio. Select the HDTV input using the TV remote.<br /><br /><img src="alexander404.jpg" /><br />

Tip

So you just got your new HDTV and the piture isn't as good as you thought.


There are some things you need to know when setting up your HDTV.

First off, you need to use HDMI cables to connect your tv to your cable box or you will not get HD. That being said the first thing you will find is that HDMI cables are expensive. Although you can buy a really cheapo cheap one, be careful. Make sure it can support 1080p or the max resolution your TV displays at. Some of the cheaper ones can only support up to 720p.

So you hooked it up to the cable box using an good HDMI cable and you still do not have the picture you should. There are a few things you may still need too do to get 1080i out of it. Yes, I said 1080i. Even though your tv may be up too 1080p, cable and dish networks only transmit up too 1080i. But don't worry, 1080i is amazing for cable/dish.

First thing you need to make sure of is, does your cable/dish receiver support HD? If you have had the same box for a long time, it may not. You will have to call your provider to get an updated box. If you recently got cable/dish and the box is new, most likely your good to go. Also, it will most likely say on it, HDTV, 1080i or something related to HD on it.

Now you are good to go with you box because it is in fact HD compatible. Some cable boxes may need to be configured for HD. You don't need an HDTV signal if you don't have an HDTV, and not every one does, so why send the unit configured for HD. You need to go into your cable/dish settings and make sure you set the HD set up to display in 1080i.

Okay you set the box to 1080i. There still could be some setting on the TV if your not getting the best picture.

Make sure you are on an HD channel. Make sure you do not have zoom on, and that the TV is set to display an aspect ratio that is determined by the program, or auto. Not all TV's have these settings. Likewise, some tv's allow you to select the max resolution, if this is the case make sure it is set to 1080p, the max it can be.

You should at this point have an excellent picture on the HD channels. Not all channels are HD.

Now, a few other things not worthy as a new owner of an HDTV.

a standard dvd player does not play in high def. they have a max resolution of 480p. 480p is going to look really good if its the first time you watch a dvd on an HDTV, but it can be a lot better. For around starting at $45 and up, you can buy a DVD player that can upscale your dvd's to 1080p when you use HDMI and you will get amazing picture. But for around starting at anywhere from $100 to $150 and up, you can get your self a blu-ray player that will play blu-ray disks, and give you amazing beyond belief picture, and it will upscale your dvd's.

So you got a blu-ray. First thing I can say is I hope your refresh rate is at least 120hz or better. 60hz may disappoint you with a blu-ray player.

Blu-ray can play movies in their native 24 frames a second format of which they were filmed in. However, at 60hz, you will run into a problem trying to play the movie in 24fs. now I am not going to get technical with this, just to let you know, you need 120hz or better to use 24fs. You can turn it off, but you will get blur and it will not be as smooth. As well, with most players you must enable 24fs in the settings, usually by default, it is off,

So to recap:
  • Make sure your cab/dish box is HD compatible.
  • Always use HDMI cables.
  • Check settings on cable/dish box and make sure its set to 1080i.
  • don't use zoom.
  • If applicable, make sure tv settings are at max res of 1080i
  • you need an upscaling DVD player or Blu-ray player to watch your DVD's in HD.
  • Also must us HDMI.
  • Can't use 24fs if you have 60hz refresh rate, but can if 120 or better.
  • 24s is usually off by default.

I don't now how i recive tv chanels in hd


Your source has to be in HD like a local broadcast TV station currently broadcasting in HD which you get with a VHF/UHF antenna connected to the HDTV. Most primetime TV shows are in HD so using the antenna on the HDTV is all you need. Press MENU on your TV remote and make sure you have ANTENNA set instead of cable to get local TV stations.

You also could use your local cable TV provider. You would need digital cable service and a HD cable box with HDMI or component video cable hookup to the HDTV. HD channels are typically above 100. Call your cable TV provider for more details.

Read your user manual for the LG TV. Ask for help from family, friends, neighbors, local electronics shops.

How do I go from 480p to 1080dpi on my 65inch HDTV


If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.

Samsung lcd 720 ln32b360 doesn't fill screen in 16:9 mode. Went through tv setup, connected it to hd box (verizon Fios) plays all HD channels but does not fill screen as it should. TV is connected to set...


If by regular cables you are talking about the standard red/yellow/white composite cables, then, yes, it will affect HD as composite cannot send an HD signal. Only HDMI and component (red/blue/green video only) cables.

Change to HDMI and let us know if it works for you.

HDTV Cable box conflict


This set does not support 480I in the DTV mode, only 480P and 1080I is supported. Try setting the analog setting in the cable box to 480p and that should take care of watching the set in DTV. Most cable boxes have a setting for format changes in the customer menu, depending on the type of box. If you are able to change the format, then the other inputs will not work since they need a 480I signal, as well as VCRs. Another setup could be to use the S-Video cable or Video input jacks to get a better picture in 480I instead of using the cable input. However, when changing from HD to Analog, you will have to change to the correct input on the set as well. Hope this helps.
