First, if you do not have 9" crts in your RPTV then your set can not possibly do 1920x1080i. Even at that it is still using a line doubler. That is not the same as 1920x1080i native. Also, if someone has seen an HD LCD that can do 1920x 1080i please post here. I do not believe that a native 1920x1080i LCD currently exists. Also the new DLPs that are claiming 1920x1080p are 960x1080p chip sets that use line doubling technology to reach 1920x1080P -- that is not a native 1920x1080 picture.

I think either you're too much into Voom's marketing or you just want to justify HD lite man

The 1080P capable LCDs have been around quite a while, we have a 23"er here that does 1920x1200 (though it's a computer monitor NOT a TV), and I know of LCDs that do well past 2560x1600 (30" cinema display there)..

Granted that, if you want a cheap and easy 1080P LCD, there's always those dell 24"ers -- they don't do HDCP (thank goodness haha), and don't have a remote for the power button, but they will function just fine with most DVI signals I'm sure..

As for LCD TVs in the 1920x1080 res, they do exist:

[as far as the monitors, apple, samsung, NEC, and dell make 1920x1200 ones that can do 1920x1080 just fine]....

witch is the better contrast ratio ? 800:1 or 3000:1

I am just passing out info. You can chose to believe or not. Hd sets that have a native 1280x720p or 1366x768p resolution have a pixel for every pixle of resolution. That does not mean that they do not receive the 1920x1080i signal -- just that they downrez them to the native resolution of their 720p or 768p output.

Now there are some LcOS screens boasting of 1080i(p) on the market. Sony's new SXRD screen is one but those are 5 digit screens ($10000 and up). Also if you do the math you will see that it is extreemly hard to squeez a 1920x1080i native resolution under 50". This is one of the reasons why most manufacturers use line doublers. Very few will actually print the actual number of lines a HD set puts out.

As for computer monitors, there are some whose resolution is in the strastophere. But we are talking about HD TV/Monitors not computer monitors. And there are no -- I repeat no DLP chips currently on the market that do 1920x1080i(p) natively. The newest chip does 960x1080p and uses a form of line doubling (they call it wobbling) to get to 1920x1080. This is not a native 1920x1080 pixel for pixel output.

Just so that everyone understands -- native in a tv or monitor means that there is a pixel for every picture pixel sent -- no linedoublers, no wobbeling , no majic tricks. The set that I have is a Pioneer Elite 58". This set produces 1400x1080 lines of resolution. The Pioneer Elite 65" did 1650x1080 lines and that was with 9" crts. I had a Sony XRB 57" that I found out had 1000x1080i lines of resolution. Mitsubishi's, Hitachi's and Panasonics were running at 1200x1080 lines on there 7" CRTS. Toshiba's had 800 lines on their 7" CRTs and boasted of 1600 lines of resolution! I believe that on Mits' and Hitachi's top of the line 9" CRTS they are now at 1920x1080i but they are not cheap! It is all numbers game and so far in order to get a real 1920x1080 HD TV/monitor you are going to have to shell out more money the the average consumer is willing to. HD to the masses is not going to be 1920x1080i. Not at least for the next 5 to 6 years.

My original input was that with MPEG4 you will get a much better picture than you have been getting with MPEG2. There will be more bandwith and less picture loss with the new alogorithms. Your HD sets reguardless of native resolution will shine with more bandwith even if they do not go to a full 1920x1080i picture. Here in Raleigh, NC the highest resolution OTA is CBS at 1440x1080I. Why would the E* or D* have to show more resolution than that? And with Fox and ABC at a 720p resolution why would you want to degrade that signal by uprezzing to 1080i(p)?

At the last HDNET symposim on OTA HD most of the individuals participating agreed that in order to send out a 1920x1080i picture -- must less a 1920x1080p picture that all of the stations broadcasting with multi-cast (more then one program on a digital channel, ie. 5.1, 5.2, 5.3) OTA HD would have to move to MPEG4 too. This would include us having to have MPEG4 OTA receivers. Don't believe there are any of those on the horizon yet.

Aren't you guys forgetting the LCD sets out there that can do 1920x1080 natively? 1080P? yep

Yep, I forgot LCDs. Sharp and others have 1080p LCDs out now. Plasmas will follow in 2006.

BTW, all 1080p displays are progressive and refresh at 60 Hz. All 1080i content must be "line doubled" for display on these sets. There is no way around that. The quality of the scaling depends on the chipset in the TV. This is true with the variety of DVD players that do 480i to 480p conversion.

Also, the quality of wobulated DLP vs. "native" 1080p LCOS and LCD is under great debate. Sound and Vision just reviewed the new HP 65" DLP using a wobulated chip and found it resolved nearly all of the detail of their 1080p test pattern. Sony SXRDs are more reasonably priced than the five figure Qualia 006 released earlier this year. The 60" SXRD can be found at $5,000 and under.

*shrug* blame the broadcasters for being too cheap and wanting too much profit
