    You could tell us what model it is.

    If you tell us the maker and model number, I'm sure someone would let you know in about 30 seconds.

    As far as I can tell, it looks like a SDTV, with no component inputs or HDTV (or EDTV for that matter) capability.

    Yeppers, a dead give away. No Component Video Inputs.

    480p cannot be carried by svideo or composite connections.

    Remember, the older DVD players with component did not do progressive as well. The t.v. has to accept a signal strength of 50hz from video to do Progressive.

    Sorry Jerome, but I just can't figure out the meaning of your message. First of all, it has little or nothing to do with the original question. Second, older DVD players may not have done progressive conversion as well as newer models, but the video signal that they output would be identical (it's the content of that signal which may be inferior). Finally, a 480 line progressive scan signal has a horizontal frequency of 31.5KHz. and a bandwidth of about 6.75Mhz, so I'm not sure what your 50Hz number is referring to??

    Sorry about the incorrect numbers and I will defer to your numbers in regards to 31.5KHz and 6.75Mhz. The reason I raise this is if your t.v. is an older model, and has component video inputs, I believe that the older model t.v. didn't meet the frequency and bandwith requirement hence the progressive signal wouldn't pass. This was an issue with the older RPTVs as well as the tube t.v.s. That's why I was raising it, but if his t.v. doesn't even have component video, then I guess we can call the post pretty much a waste. Sorry again.

    Couldn't you guys have just said, no component inputs plus the fact it is not a "digital" EDTV/HDTV TV translates to NO progressive scan of any kind? The whole discussion about KHz and MHz can be really confusing.[​IMG]

    Do not simply plug in a progressive source to see what happens. Some video equipment can be damaged by the input of too high a scan rate. I don't know why, but I read that in a manual for an old IBM made PC.
