About a year ago, I purchased a Mits 4:3 (VS-60805) screen and have just recently purchased the Mits HD400 Direct TV Plus HD receiver. Contradictory to what my salesman said when I purchased the screen, I have discovered that 4:3 DTV broadcasts appear with black bars at the top, bottom, and sides of the screen. I would've expected that the 4:3 broadcast would fill the 4:3 screen. Have I been had?

I have a VS60805 4:3 with a Panasonic TU-HDS20 STB. When I had the STB accidently set for 16:9, my 4:3 DTV broadcasts came out with bars on all sides, no matter what aspect ratio I selected. When I set my STB to 4:3, everything appeared correctly, 4:3 DTV shows at 480p/i would fill the screen. When I select 1080i, I get the usual letterbox.

On the Mits VS-60805 4:3 screen, DTV SDTV signals that are 4:3 aspect ratio have top, bottom, and side panels. The signal from the Mits HD-400 DTV receiver is 1080i, not 480i or 480p. Alternatively, the SDTV signal can be translated to 4:3 480i however, the picture appears stretched vertically and the side panels remain.


My dealer told me that the DTV SDTV signal with the Mits VS-60805 would fill the screen. It does not. Does anyone know of any tricks or equipment that will expand the SDTV picture to the full dimension of my 4:3 screen?

I have the Mits VS-60803, which is similar. I believe that the 4:3 HDTVs will only fill the screen when presented with a 480i or 480p signal.


In reviewing
Twice's List of Digital Set-Top Decoders

it would appear that only the Panasonic TU-HDS20 STB (as reported by Lee) decodes both OTA and satellite and convert all formats to 480p. (There are STBs that will down convert to 480i, but what's the point?) The list, which has not always been accurate, also shows that the Zenith, will output 480p and is supposed to be released next month.

LeeG,


I have the same brand as your TV and STB. I have a question for you: component video hookup doesn't work at all, I'll get a green picture. However, the RGB is working just fine but I have to run 2 extra cables to the TV from

the STB. The Mits manual recommends that we should use component setting. What is your setup? If you have component setup, what did you have to do to get it working?


Thanks,

I run YrPbCr cables from the HD-400/500 STB to the HD YrPbCr input (1080i) of the TV. H and V cables are not used, so I just leave them hanging unconnected. I've had no problems with this configuration.


Never tried connecting the STB to the component inputs on the TV. I suspect this wouldn't work too well since the component input on the TV expects 480i/p. I believe there are other issues as well such as synchronization (on green).


Good luck.

heskech,


Let me clarify to you. My HDTV inputs have both options:

component (YPrPb)and RGB (H+V) (RCA type) inputs for HD format. I do have other component (YCrCb) for DVD player which I already used for it. However, the manual suggests that I should use component (YPrPb) for HD, but to no avail when I tried it (synchronization problem). It does work with RGB (H+V) connection. The Panny STB have two output options for HD: component or RGB (H+V)(RCA type input). I wonder if the component cable I use has anything to do with it.


Thanks,
