RPTV that can show 720p w/o conversion? (1 Viewer)

ashley__cooper · Oct 1, 2003

I've been looking, but I can't find anything that will do this. Also important is not converting 480i to anything else either. Basically no automatic conversion. As an indie filmmaker, the accuracy is important.
Thanks ahead of time for any help!

um....there are plenty out there, like my Philips 55PL977S/3. It's 720p native LCOS RPTV. Plus almost any DLP.

I don't think LCOS/DLP/LCD based sets would solve the OP's problem, wouldn't 480i need to be converted for LCOS?

Samsung DLP.

John_F · Oct 2, 2003

Won't the Samsung DLP convert 480i?

Mind you that HD sets also convert 480i to 480p so conversion of one sort or another is unavoidable.

Oops... I shudda read the whole question.

Current Samsung DLP's native display is 720p. Everything coming in is converted to that (including 480i).

Sorry.

Michael, I was not aware of that, I thought there may be some CRT RPTV sets that display 480i "natively".

Thanks.

He really states 2 questions...

1. no convert on 480i
2. 720 native

You can't have both, but any DLP and LCOS will give you 720p native. Any non-HDTV RPTV /w componet inputs should do 480i.

Are these being sold anymore? I checked Panasonic, Toshiba, and Sony web sites, and all of their current RPTVs are HD compatible.

Also, do you need component inputs to do 480i, I thought that any connection (composite, S-Video) could pass 480i?

Thanks,

I believe NTSC = 480i. So I believe any connection will do.

There was a time when you could get a set that did this. A Panasonic RPTV from 4 years ago. It did 720 native and you could turn the line doubling off for 480i native material.

I have not seen a TV since the 2001 Pannys that could even disable the line doubling.

DuWayne, I am not familiar with the term "HD Upgradable". Could you please provide a a manufacturer and model # that has this?

Thanks again.

Thanks for the help, but I'm still a little confused. So it's not a possibility to get an HD rptv to show 480i native w/o conversion even if I don't go through the external HD converter?
So is my only option to find a 2001 panasonic? If so, could someone please give me some model numbers or somehting?
Am I crazy, or are these tvs just not designed for people with precise technical needs? Would I have better luck with projectors?

The ones listed above should do 480i without HD box. BUT, you can not have a set thats says native 720p or 1080p/i and display a 480i source without converting.

Look into professional studio monitors rather than consumer TV sets. Consumer TVs don't support multiple scan rates so they can be made cheaper. You'll have to spend a lot more money to get what you are apparently looking for. It may be impossible to get something that does both 480i (15.75 kHz scan rate) & 720p (45 kHz scan rate); you might have to buy 2 sets.

Fixed pixel display will also never work for this.

You'll have better luck with CRT front projectors; 480p->720p should be no problem to find. Don't know about 480i though. Don't you have a normal TV around you can use for the 480i?

Matthew Todd · Oct 2, 2003

As mentioned above, the only way to do this may be with a CRT projector. I've got a CRT front projector, and it can be fed any scan rate you want from 15kHz to 105kHz, so you can do 480i, 720p, 1080i, 1080p, etc.

You can set up a CRT front projector be be a rear projector, and I've even seen some that were manufactured that way with a built in screen (that's really what an RPTV is anyway, except that it's difficult to find consumer models that do multiple scan rates).

Used CRT projectors (and if you're lucky you may find one that is pre-setup for rear projection including the built in screen (e.g. I've seen an Ampro 3600 Retro like this) are about the same cost (or less) as an RPTV. The Ampro 3600 Retro I saw was available for $700, but they can be pretty hard to find.

DuWayne, thanks for the clarification. I guess I got a little confused by your phrasing:

I see now that you are refering to the original posters specific question.

I didn't think that "HD Upgradable" was a industry accepted terminology, for example, I believe Toshiba calls this HD compatible.

I guess I don't like your definition of HD upgradable because it seems to differ based on the display technology. For example your definition applies to RPTVs, but if you look at the Mit's plasma, they call it "HD Upgradable" even though it will accept 720p. Isn't Mits definition of "HD upgradable": an external HDTV STB is needed.

Sorry for hijacking the thread.

DuWayne · Oct 3, 2003
