Info per htwait's request:
This thread is all about the 2007 Samsung HLTxx87/89S LED DLPs. Each series comes in 50", 56", and 61" versions. All of these sets are 1080P and appear to have the same cabinet. As of 2 April, the suspected differences are:

Samsung seems to be using the same photo for all six televisions in this line (HLTxx87/89) on their web page. I don't know if they all have the same proportions or what.

Frequently Asked Questions:
(I don't have all the answers yet)
Is the color banding still there in the new HLT's like it was in the 2006 model or is that fixed now?
Will the AUDIO OUT send through signals from HDMI as well as the normal analog sources? (Will it pass 5.1?)
From Morseth: I didn't see any banding in any of the video modes (dynamic, normal, movie). That doesn't mean it isn't there because I haven't done any exhaustive tests, but I have yet to see it with casual viewing.
From Kagaden: I didn't notice any out of the ordinary with VGA, Standard Definition, DVD's, and Component Wii/PS2 on any mode I fiddled with. I don't have a PS3 or Xbox yet but I'm sure the picture quality is worlds better. My initial impression is that this set corrects the problem I've read with last years 5679's.
Is Samsung finally doing 3:2 pulldown correction for 1080i sources to get back the 1080p/24 signal (used to only work for 480i). Does the 120 Hz refresh rate compensate for this?
From Gene S: IIRC, using the sets internal tuners will pass 5.1 sound on the optical out. Using external devices, (STB's, PS3, TivoS3...) the set will only pass 2 channel sound.
Is the contrast up to the level of the wheel versions?
From Studio Dweller: I'm a friend of Eliab's and we picked up two of these sets on Thursday. Eliab told me later that day that the HL-T5089S does indeed accept a 1080p/24 signal.
From llowrey: My understanding is that these are wobulated sets and that wobulation occurs at 120Hz (60Hz x 2). I am wondering if this 120Hz number that's been going around is not the true frame rate but rather the wobulation field rate.
**In other words, we don't know the answer yet.**
Is the pincushioning better/worse than last years models?
What are the foot dimensions?
From Moreseth: My pincusion in 4:3 material is less than 1/8" on each side. It's so small I can barely measure it.
Samsung quotes a 16 microsecond response time. Isn't that slower than most LCDs? Wikipedia says that typical LCD response times (how fast the pixels can change colors) is 8-16 milliseconds. Samsung claims a 16 microsecond response time. There are 1000 microseconds in one millisecond. To compare apples to apples, the typical LCD response time is 500 to 1000 times slower than what Samsung is claiming for these DLP sets. Keep in mind that this does not include the time that it takes to process the signal (input lag). To dumb it down, think of it this way:
From Moreseth: The dimensions of the actual footprint of the 6189S is about 41" wide by 13.5" deep. These are maximum dimensions, since the footprint isn't a perfect square. (Still waiting for 50" & 57" measurements)
1. Video signal goes to TV set.
2. TV set processes signal and converts it to 1920x1080 pixels to display on screen (input lag). The prettier you want the picture, the longer it will take.
3. Light engine throws picture up on the screen (response time).
Game mode cuts down time in step 2. Obviously if the set had an overall response time of 16 microseconds, we wouldn't need game mode. What it does mean is that the screen itself can keep up with any kind of fast moving action. Here's some more food for thought. Let's take Samsung's quoted 120 Hz refresh rate. You'll get a new screen every 8.33 milliseconds. Analogy: I could have the fastest drumroll in existence, but if I'm only allowed to hit the drum once a second, you're only gonna hear that drum once a second.
Rainbows? I thought LED=no wheel=no rainbows. Can you see them on this set?
Info from the Spec Sheets:
If you are very susceptible to rainbows then you might be able to see them on this set. Some people who can see them on lamp based DLPs report not seeing them on the LEDs. Rainbows are caused by the cycling of colors, either as a color wheel spins through them or as the LEDs cycle through them.Quote:Originally Posted by htwaits
The underlying cause of rainbows is the fact the each basic (red, green, blue, etc,) color is flashed on the screen one at a time to create the exact color that is desired. The advantage in using colored LED lights is that they are faster and there are no gaps between color filters like color wheels have.
Here is a discussion over several posts about LED light engines and rainbows. I'm surprised that someone has already felt that they are seeing rainbows. Be sure to read what collinp has to say on the topic.
