2007 Samsung DLP Information From CES! - Page 22

We both forgot what bfdtv reported from CES 2007.

Samsung also had a new 72" lamp-based design at CES (HL-T7288W), but it was not a slim profile display -- depth was 20".

Check his report in the first post. He did update his notes about a 2007 71" set with a different model number sometime after his initial report.

I recall that Brillian's LCoS set had a 120Hz refresh rate, but it didn't accept 1080p@24Hz input. Samsung may be going part way too.

I noticed that in your picture of the place card there is HDMI 1.3 and USB 2.0. In the "final" pdf files for the "76" series there is no mention of the HDMI version and USB is listed as version 1.1. Information is still skimpy.

I'm naive about this stuff, but would a TV capable of a 120Hz native refresh rate care what the input refresh rate was -- 60Hz input x 2, 24Hz input x 5?

It's going to be interesting for a few weeks.

All 1080p DLP RPTV sets in the market are expected to be wobulated for 2007. It makes no difference which company builds them.

Since the first 1080p RPTV sets arrived in 2005 they have all been capable of projecting 1920x1080 uniquely controlled pixels on the screen. The term "true 1080p" is a marketing term.

The resolution on the screen is not "mimicked". It's alternated at a very high rate of spead. Much faster than film where we're shown a still picture every 24th of a second and we think it's a "moving picture show" or "the movies".

These two links deal with wobulation more intelligently than I can.

Wobulation is, from a user perspective, a NON-ISSUE.

It's the speed.

The wobulated DMD 1080p chips have 960x1080 = 1,036,800 mirrors. Each mirror is responsible for controlling the content of two adjacent pixels on the screen. Each of those two pixels is supplied with it's own unique information depending on the image being displayed.

The mirrors on the DMD chip do their work so fast that your brain and vision do not detect any gaps in the presence of pixels on the screen. What is projected is true 1080p even though the 1,036,800 mirrors "wobble" between pixel A and pixel B.

Think very very fast.

TI has a DMD chip with 1920x1080 mirrors. So far it has only been used in high end front projectors. Optoma and others have introduced mid range (~$7k) front projectors using that chip. At this point a 1920x1080 mirror chip may be too expensive for the RPTV market.

All the wobulated 1080p RPTV sets are "native" 1080p because you perceive all 2,073,600 unique pixels as being projected onto the screen at the same moment. The fact that they arrive at slightly different times is not perceptible.

This link is to a post by collinp on other wobulation issues.

TI has increased flip rates and DLP processor throughput.

Well said!

Then we can work on the format war and high prices.

Are you saying that Circuit City has HL-T models on display? Which ones?

You may be the first to see one.

By going to the download center at Samsung's US web site you can find material about the HL-T "75", "87", and "89" series of models.
