Samsung HLS-5679W LED DLP Owners Thread (*NO PRICE TALK) - Page 29

If so by what margin (i.e., how much more is the display capable of), and is there a way to see the richer colors (maybe RGB over HDMI instead of YCbCr?)

If not, how close do current displays come, and is the HLS-xx79 capable of displaying a wider gamut of colors than the 87/88?

I'm sure this has been discussed on avsforum but I was unable to find answers via search. Pointers to old threads are welcome. If my question makes no sense because I'm confused, please tell me I'm confused. By the way, is ITU-R BT.709 the actual broadcast standard that governs the HD color gamut?

The weakest element of this display is the black level is higher than the lamp based HLS series products. The reports of the iris not being adjustable are also false.

I have attached the calibration data to this post.

I was reading that you were able to correct the banding issue for the 5679.
I was wondering if you could give us more details as to what adjustments
you made to correct the banding issue.

I am already having the digital board replaced. I would suggest that everybody
contact samsung and let them know that the banding issue is unacceptable
and needs to be corrected.

Thanks

Hahahaha, guess not. But if anyone knows of a good CALIBRATION guy near or in Ottawa, Canada ... Please let me know.

Still on the fence between this set and the 52" Sammy LN-S5296D LCD Set. It's just that I know I see pixel break-up on LCD. Not sure if this is corrected with the new LCD models on the market. Either way .. "GOTTA GO SAMSUNG" .....

BTW, if you did not see it GO HERE and see that the LED DLP came second for best showing in Projection sets at "Best @ CEDIA". SXRD is nice .. but lamp replacment at 3000 hours and no 1080p over VGA or Component ... Nahhh ... I'll stay on the Sammy side of things.

I own the 5679 Set that UMR calibrated yesterday. First things first, the difference is stunning. I went from an absolutely unwatchable "custom" mode to a beautifully colored picture with none or *very* little banding in custom mode. When I say very little I mean equal to or less than the previously uncalibrated movie mode. Now I leave movie mode alone and go custom for everything. He does have some minor tweaks in the user menu depending on my source but the overall user menu stuff leaves sharpeness off (zero), and contrast set at 95 or 100 depending on the source.

The only real downside of the set that he could see what the contrast ratio looked to be around 1000:1 but I honestly don't think I could tell the difference in my viewing area.

Another major improvement he made was black levels. I used to see a thin grey stripe in the black bars on certain SD Dish Network channels (namely Sci-Fi). That strip is supposed to be invisible but showed up on my set pre-calibration. He can get into the details of that as I don't know what he did to correct it. It's gone now.

To sum things up:

1) I no longer use movie mode. Post-Calibration custom mode blows away movie mode pre-calibration.

2) My colors are now balanced and the "cartoonish" colors are gone. The colors are consistent from source to source. He took extra time to examine my Dish VIP622 HD-DVR, my Samsung 1080p DVD player, and my OTA signal.

3) My black levels are vastly improved which makes me very happy. This not only adds depth I can percieve but removes artifacts on the screen in many cases (that damn thin grey line on the black bar)

He's also very knowlegable about audio but I don't have much to work with in that department, yet.

I would also like to add the UMR came *exactly* when he said he would and was very professional. That's saying a lot because he traveled from Texas to North Carolina on this tour. I sure hope he's around when I get my next set.

There's a consumer reports post for calibrators somewhere on the forums but I forget where. Can someone tell me where to post this great experience in the proper place?

Enjoy.

I was even able to turn on DNle while watching the tapes on Dynamic Mode and you guess it, No banding..... I even recorded in SD, played back the tapes in ALL the Modes and no banding.
Any ideas ???........

I do come very close to Canada and have traveled there in the past for my previous job. I will say these sets are even more difficult to calibrate than the lamp based HLS products. The very saturated primaries are also likely to cause even more problems with less than stellar measurement equipment.

I am sure their are better out there, but I use the Home Theater Calibration DVD from "DISCWASHER DIGITAL" to help with my greys, blacks, whites and prime colors. It also has audio calibration for DTS and Dolby Digital which is nice.

It addresses
-Contrast/Black Level Setup
-Brightness Setup
-Sharpness Set-up
-Color and Tint Setup

It is a few years old, but I find it works not to bad.

Do you go into a service menu ??? I assume you do !!! Anyway us "COMMON FOLK" can get access to it and will it be useful in correcting the overscan issues some have seen?

Cheers
