The Sharp website is pretty useless and actually doesn't list most of the models they sell, expecially the new ones. I'm wondering if someone in the know can help decode the model numbers. I'm guessing it has to do with generation, location/factory made, and some features. If there is a ryhme or reason to the model numbers? It would be great to know.

In the 65" range I know of the following model numbers:

LC-65D90U
LC-65D92U
LC-65D93U

In the 57" range I know of the following model numbers:

LC-57D90U

In the 52" range I know of the following model numbers:

LC-52D43U
LC-52D62U
LC-52D64U
LC-52D82U
LC-52D92U

Fry's had a LC-65D92U on display a couple weeks ago and then yesterday they were showing the LC-65D93U. The people who worked there of course has no clue that there was such a thing as a 90U, 92U, or 93U. The 93U looked really nice.

Here's the strange part. Shopping for a LC-65D92U is more expensive than a LC-65D93U which seems odd to me. Anyone have an idea as to why that might be?

Any help would be much appreciated.

Thanks,
jp

I got an email and ended up talking with a Sharp rep who gave me some info.

In general the higher the number the more connectors and features the unit has. For example the 92/93s have 5 wavelength light where as the 62, 64 have 4 wavelength. The 92/93s have higher contrast ratios than the others too.

Some interesting tidbits:

The LC-65D92U was a "not supposed to ship" model and was quickly replaced with the LC-65D93U nomenclature - no difference in specs.

The LC-65D90U is last years model, discontinued.

What coming is the LC-65D64U It will be aligned features and connectors wise with the LC-52D64U. It has less bells and whistels (4 vs 5 wavelength for example) but only the models with 64U at the end support HDMI 1.3.

None of their other models do.

I'm assuming the LC-65D64U will also be less than the 10K they get for the 93U version.

Basically it seems like Sharp is a little bit of a mess with things necessary to keep up with Sony (i.e. HDMI 1.3 and all that comes with that) and their other TVs that have all the features besides HDMI 1.3.

I would love to read a comparison of the LC-52D64U against the Sony 52" XBR5.

Lastly, we'll have to wait a bit for the 65" 64U model to see how that fares against the 93U version of the 65"

I felt the same. It is very confusing the way Sharp comes up with model names!

1) See the attachment of 64U brochure
2) See article from Sharp: http://www.twice.com/article/CA6470121.html

I am sure, you will have the brochure for 90 series.

Thanks for the post on the brochure. Adding HDMI 1.3 with increased color gammut and taking away 120Hz image processing on the 64U? Grr. Have to wait for the LC-65D94U it seems to 'have it all'

It just seems to be a bad time to buy a sharp. Bummer. I really enjoyed my last one (37inch 1368x766 model).

Seems like Sony has the edge.

I did run into a brochure on the samsung claiming 500,000:1 dynamic contrast range. Doesn't that seem excessive? Is that possible? Is it even desireable? One thing i've noticed is that people want "BLACK AS HELL BLACKS" except when I watch things that are Black, like a black blazer or overcoat, you couldn't see a lapel if your life depended on it. Sigh, will I ever be happy?

Right now, I really enjoy my 34" CRT XBR - 960 Old School Glass TV. The picture is perfect. And I can't really complain about my old Mitsubishi 65-905 CRT TV (as long as its converged).

Still waiting to jump back into the flat panel pool,

I don't have much choice. I already placed order and expected to receive the set soon. I spoke to Sharp technical person and discussed for almost one hour. He seems to be thinking very high on LC65D64U. He says that the earlier models had banding problem. They have been corrected in all new models being manufacture for last 1+ yrs. I will post my feedback after I receive the set. Thanks,

If I had to choose between the 120hz processing (it's not the actual refresh rate on Sharps (again, only Sony has true 120Hz refresh on the pixels)) and HDMI 1.3, I'd take the HDMI 1.3. So I wouldn't be too bummed and yeah I bet the banding problem is non existent with the right source feeding the 64U.

What blows me away is that the color space with every current HDTV not hip with HDMI 1.3 can only display 256 shades of red, green, or blue. I think the HDMI 1.3 spec goes up to 48 bit or something insane like that (281 trillion). Regardless, with 1920x1080 pixels there are lots of opportunities to run into the 256 shades of blue for example and get banding. I've seen most sets going to 10 bit which allows 1024 shades of each. It's not 'perfect' to eliminate it, but you would have to try pretty hard with a video scene to get some banding. I'd like to see it settle out at 32 bit with 65,536 each which is native to what computers do.

Anyway, enough rambling, I hope you enjoy your set, I would like to have it myself. where did you get it from? Let me know how you like it.

thanks,
jp

From Sharp Direct. My order is not yet processed. Heard that they have received much more orders than expected. The sets are still being produced at factory. Thanks again for your reply.

Any updates gents on the 64U, has anyone compared the 2 models, 93U and 64U? I really want one of these sets and I cannot decide which one.. Go for the increased contrast ratio and 120mhz of the 93u or settle for HDMI 1.3 on the 64U... Does anything even take advantage of HDMI 1.3? Is it a waste in terms of current equipment?

Help!!

I thought the 32 bit setting on most computers was RGB+Alpha (ie. 3x8 bits for the RGB + another 8 bits for the alpha channel?).

So it's more or less the same as HD Media, except for the fact that HD media only use a limited range of values for each colour (eg. something like 16-235 instead of 0-255) so you end up with about 10.6 million colours instead of 16 million colours on HD media which may make banding more likely as the range of colours used is less.

And, besides, 2^16 = 65,536 << 2^32

Years late but what the hey. This is from CNet.com

Example:

Sharp LC-80LE844U

LC: Product category. "Liquid Crystal," presumably. Blu-ray players are BD, for example.
80: Size
LE: Type. LE is LED LCD, whereas SV is regular LCD. 844: Series.
U: For any company, this almost always means it's a U.S. model.
