I updated the DLP chip information. I also included the comments below in the questions area.
Example of spec update:
> DLP Chip: per Samsung, Latest 1080p (xHD4 --- neither Samsung nor TI are discussing chips, this is our best guess given available information)
12. What TI DLP chips are used in the new models?
Comments By UCSB (AVS Member):
We have an open issue about what DLP chips are in these new models. It seems that TI (Texas Instruments) and the HDTV vendors have gotten together and decided not to talk about chips, but rather talk about 720p chips and 1080p chips. I can understand this desire on their part. With models coming out at different times during the year, everyone can't have the latest chip and a lot of other things go into the design of these HDTV's (firmware, optics, electronics, screens, etc.) beyond the chips. Part of me says that we should just respect their wishes. But, then part of me says wait, for most of us these are expensive purchases. We have a right to be informed about what we are buying. Could you imagine if Intel decided we are just going to refer to CPU's by their type, Pentium 4's for example.
We have gathered a lot of spec's at CES 2005 and those spec's are clearly documented in the posters, product display cards, and press releases that we have been accumulating. I think some clear patterns have emerged.
It seems to me that Samsung and TI cooperate closely on the introduction of HDTV's and DLP chips. This is to be expected (I thought I saw a press release saying Samsung had 69% or the DLP market). Samsung has stated they are using, or will be using TI's latest chips. So here is my take by model line.
Series 68, 78 - TI xHD4. I don't know if this is the designation they are using internally, but this is the next 1080p chip after the xHD3 shown initially at CES 2004. When the 68 / 78 product arrives it will be mid 2005. Clearly at least one model year removed from the 2004 chip we saw last year. The xHD3 had a contrast ratio of 5000:1, these new chips are claiming 10,000:1. In addition, there was a Zeiss Optics pdf document that talked about compability with the xHD4 chip.
Series 88 - TI xHD3. This 1080p pedestal HDTV was slated for introduction last November with xHD3. It's lower 5000:1 contrast ratio, 2004 develop time table, and early introduction (FEB 2005) led me to believe that it is based on the xHD3.
Series 67 - TI HD4. A couple of vendors, Sharp and Optoma, created product display cards stating that they are using the HD4. So we know this is the latest 720p chip. In addition, Samsung is claiming a 2000:1 contrast ratio just the same as in the Sharp HD4 720p HDTV. Optoma claimed 2500:1.
Series 87 - TI HD2+ or HD4. We do not have a single picture, product display card, press release spec or really anything on this HDTV. My guess is that they just left the HD2+ chip in the unit (ie used current HLP5085W as base).
