Can you see what the settings are for the Picture Details and Options menus when this is enabled? Also, what are the brightness, contrast, and other settings set to?

He wishes to make us unhappy about his purchase as well, and it's NOT working!

I own the 67" model and need a 67-73" screen for my viewing distance, if there was a better option for under $5k I would have taken it (although I do question if the Mitsubishi Diamond might not have been a better choice).

I'm happy with the TV (just posted my settings, prob far from what most will like... which is fine) but I'm also aware of it's weak points (as most every display has) and think it's only fair to let people know when they come out and ask... Lots of LCD and Plasmas offer better shadow detail, better blacks on some of the high end LCDs.

Best wishes! Your forum continues to give us tweakaholics the fix we need daily (some more than once a day). As great as the forum is, make sure you keep the wife happy first. ;-)

So much great work by Lee Bailey, jrcorwin, Low tech, Yahwey, others. Sorry I've been away so long, just got married and back from my honeymoon.

I'd like to add links in the first page FAQ, calibration info to some of the awesome posts that have been done recently. I may be missing a bunch, but so far the ones I know about are:
http://www.avsforum.com/avs-vb/showt...4#post15926394

http://www.avsforum.com/avs-vb/showt...8#post15866868


Any other good ones I should add? Let me know, and I will try to find time soon to add these links to the start of the thread. And, hopefully to actually TRY some of these settings!! Just been so crazy lately.

Doesn't everyone just want to give rmz76 one of those friendly head-locks while rubbing the top of his head with your knuckles--saying, "ya crazy kid ya"? ;-)

Honestly, I don't mind a little dissension. After all, look at what president we got stuck with after the majority drank the Kool-Aid. However, in this case, my money is on Lee's settings with some individualized tweaks.

After using his SM settings, and adjusting user settings using the AVS HD disc and the Wall-E calibration menu, I keep coming back to contrast 99 and brightness 46 (at gamma 0). If I switch to gamma -2, I can turn the contrast down some, but then the blacks aren't that good. I've mainly used Dark Knight (chapter when they escort Dent on the lower level route--I think 20) to test my settings. When I used Lee's contrast 75, and brightness 42, things seemed washed out. As I've posted before when viewing OTA with the internal tuner, I can use Lee's user settings but have to turn color down to the high 30s due to blooming reds/oranges.

All-in-all, I think the PQ is better with the new settings.

Interesting observations. So, SB Gain is no longer in play based on Lee's findings that it reverts after power off, correct? I had SB Gain at 110, and it looked nice in SM, but then I think I lost it after power up again.

I've now tested with Man on Fire (BD), Transformers (BD), The Dark Knight (BD), and Iron Man (BD). So far, so good.

I would be curious to see Lee's results if he checks this out as well.

UPDATE II: Same settings listed above, but with LED Control back to LOW. MIN seemed to just a bit too dim.

So, Lee's Service Menu settings, Lee's BD picture settings (with the exception of brightness being at 44), [0] FILM gamma setting rather than the default of [4]OEM.

"Service Menu" hex code:

I just want to make sure I got this straight before I screw anything up. From Lees quote above, this is only for universal remote and changing the SM so you don't have to constantly change the User Menu, right?

Quote:


*Late Addition*
Hit the MENU button until you are back at the Main Menu.
Cursor DOWN to the DDP3021 menu.
Cursor RIGHT to select it.
Cursor DOWN to GAMMA.
Cursor RIGHT/LEFT to change it to (0)Film.
Hit the MENU button until you get back to Main Menu area.

Power TV off , wait 30 seconds or so, then turn it back on.

Go to each input, and toggle through the modes.. Movie,Standard,Dynamic. Then stay at Movie. You can start with my settings and adjust as you want.

If I don't have a universal remote, can I only put in the above addition to the SM and not worry about the first quote and everything will keep as long as I add my own user menu settings?

Even my wife was complaining about the black levels compared to our 57" Hitachi CRT RP... the crushing blacks on this set they are that way on every floor model I've seen (and spent quite some time with several before purchasing in mid-January) so it isn't just my set and again multiple professional reviewers have noted this problem going back to the 1st generation LED DLPs.

From Thomas J. Norton's review for Home Theater Magazine

Conclusions
The Samsung does have its strengths, not the least of which are fine color performance and good resolution... But when a DLP rear projection set is outperformed in its ability to produce deep, rich blacks by many LCD flat panel displays—including Samsung's own... I have to scratch my head. Yes, the LCD set is smaller and, at least at list prices, much more expensive. But it's clearly the better set... Its most significant detraction is its poor black levels and hot spotting on the screen.

Pssst Rmz, again; Home Theater Magazine reviewed the 650 - not the 750. Two different animals, it's like saying that the Blue Whale is the biggest fish in the world, it's not, the Whale Shark is...Get it?, got it?, good!
Anyway, CNET reviewed the 750 and gave it a very favorable black performance and overall PQ review.

Fanboy or not, I'll say that for the money, these Samsung 750 DLPs are excellent TVs, and no other TV can touch it's value except for maybe the Mitsubishis - which have some annoying issues. As for comparing with your existing RPTV, it's unfair to compare anything but the best plasmas to one of the best CRT based RPTVs ever to exist.

I'm pretty sure your awesome but heavy as heck Hitachi 57" CRT cost at least double, triple, maybe even quadruple a new 750 when brand new.

That's what I did eddysnake. I haven't felt the need for an all-in-one remote yet--I like my table/lap full of remotes. ;-)

frankly....what i've seen from these sets has impressed me so far in the store...i could wish for some more pop and color (hey im young and of the generation that thinks bright oversaturated colors are good so please forgive me)...but the idea of going to 67" of 1080p for LESS than the cost of 52 inch LCD's...im there...

and add to that that it will be replacing a Samsung LNS3241D 32" LCD with a whopping 3000:1 dynamic contrast....i think im going to be blown away!

I added the three links to post 2 of this thread, and put a pointer to it in the FAQ. I hope I get some time to try these SM settings soon, but still lots of craziness going on in life these days.

Thanks for all the well wishes everyone!

Right. It just reverts back. I don't see how that can be rectified without Samsung becoming involved and I wouldn't expect them devote much time to this.

I tested it out as much as possible and I for one was very happy with the results. It was really dramatic to flip between those modes and have something on screen such as a man in a dark suit with a somewhat dark background in the scene.

I didn't really notice how much the crushed blacks were there with [4]OEM until I flipped back and forth. All of sudden (when switching to [0]FILM) I could see the detail of the suit again...the lapel and the chest pocket.

I think we may really be on to something even better if the other settings can be rechecked and dialed in to correspond to [0] FILM.

Also of note...the slight red push seemed to be lessened to some degree. Skin tones seemed more natural. A great example was Will Smith face while laying in bed (2nd chapter I believe) in I, Robot.

Hey guys,

Trying to adjust a friends TV that is out of warranty....

I am on a mission now. Who knows which screws you loosen to adjust the DMD? There are 4 screws with springs under them that are around the heat sink and then there are 4 smaller screw out at the edges of the board. I cannot seem to find what would be tilted or turned to affect the picture tilt. This cannot be rocket science.

Any help?

Thanks jrcorwin, that's very informative, I remember bumping up my brightness last night to 50 after making that Gamma change from oem1 to film and LED low to get very likable results while finishing off a 720p version of Malcom X last night -- it looked really nice - to me anyway, had that big screen plasma look to it (uniformed light, 3Dish, detail in shadow areas) and without any of the image enhancement stuff on.

Brightness at 44 will probably work equally well with better quality sources as per what you tested..bravo.

Yeh, I too wasn't satisfied with the brightness at 42, that's why I initially complimented Lee's settings with dynamic contrast, but just bumping up the brightness works better.

I'm under the impression that either Lee has his 750 in a batcave or just likes a dark-ish PQ... -or- the 67" version has slightly weaker light intensity than the 61" due to the bigger surface area...which would make sense if they both use the exact same light engine running at the same specs.

There is a photo led walk-through of this process in the service manual on page 4-26. It shows you exactly how to do it. I'll send you a PM.

Probably the most deceiving BD I tested was Mr. Brooks. Like I said, a lot of excellent dark scenes. The problem is that some of the scenes are just completely black at the bottom, top, or corners. You might believe at first that you are seeing a lack of detail, but you aren't. There is nothing there to see...it's just black.

Man on Fire was an excellent source to test. I primarily viewed the scene towards the beginning with Denzel Washington's character (unshaven at this point) riding in the back of the car on the way to meet the family for the first time. With [4]OEM it looks fine at first until you switch to [0]FILM. You then see more detail in his beard for instance. Skin tones and the darkness of his facial hair appear to be more natural as well.

All-in-all, I think the PQ is better with the new settings.

I did give Lee's settings a try for 4 days and then decided to revert back to factory defaults to see which I thought looked better and I'm glad I made that choice.... Of course from looking at others factory service menu settings it appears the 67A750 is calibrated differently at factory than 61A750 (anyone service techs know exactly what the difference is? I thought these sets shared the same light engine)

Regardless of what settings you use...Contrast and Brightness is going to have to be set for your environment.... Most everyone has at least one movie with the THX calibration tool on it, if not just burn a any one of the dozens of available brightness/contrast test images to a photo CD (I also found a few test images designed to help target shadow detail)... Would love to turn the brightness down to 44 but in my environment closer to 50 is the minimum I can get away with, mid-day 52.

I think people should be very cautious when using anyone elses calibration settings. If those settings work for you and make you happy, then great but as several pro ISF calibrators have noted these sets can trick the color sensors. Below is a post form Randy Tomlinson in the Display Calibration forum regarding Samsung LED DLPs (Tomlinson is a pro ISF calibrator, freelance author of several reviews for Home Theater Magazine). After reading what Tomlinson has to say would you really want to rely on a sub $500 ColorVision Spyder color sensor product (or someones settings derived from such device) to be your guide? According to him the color charts you're seeing generated from those sensors may not be accurate on these sets.

Not trying to pick a fight, just trying to keep everyone open minded.... We don't all have the same taste and that's ok.

Quote:


Some have noted calibration adjustments not "sticking" when cycling these sets off then on. I calibrated one today and had no such problems. In fact, I cycled the set off and on many times just to make sure. Grayscale was high (bluish) even in Warm 2 (Movie) as delivered and even more blue in dark scenes. Set calibrated beautifully though these sets do not have the exceptional color correction capability of the bulb driven sets. Nevertheless, Movie mode isn't bad.

Those that anticipate playing with primary colors (there are no more secondary adjustments) using a color analyzer should reconsider. These sets completely fool the typical tri-stimulus devices. One of my devices that's typically in the ball park differed by 0.100 (x) from my LightSpex spectroradiometer when measuring red. An error of even 0.010 would normally be pretty huge. Service menu primary and secondary color tweaks for Movie mode are now missing entirely anyway. A quick experiment with a big change in green color coordinates made no change at all when Movie mode was selected and green measured. Time for a consult with a friend at Samsung about all this. There are several opportunities for large errors in calibrating even just the grayscale of these sets. Accuracy of equipment is only one of them.

Having just turned in a lengthy review on last year's HLS set for UltimateAVMag.com, calibrating this new LED model was a very interesting experience. I expected poor contrast and color accuracy. While I sense that blacks weren't quite as dark (hard to be sure without my light meter and viewing in a lighted room), they definitely weren't too bad. Color accuracy was different from the HLS sets but still in the ball park (Movie). Overall, I was surprised and even impressed. Precalibration, the bluish grayscale hurt overall color rendition, particularly in darker scenes.

Samsung made a number of very welcome menu changes too, most of which I'd recommended in the review. Somebody there is listening, but if course it wasn't to me--the sets were designed long before I wrote any suggestions. I just didn't know they'd already changed things when I did the writing.

OK, thanks,

I can't wait to get home and Change the Gamma to Film and see what pops up, everytime a new change comes out it's like getting a new TV, I love it! how exactly do you get the image from the BD source to stay on the tv when switching to the SM? maybe I misread the post and you can't do it...

I also got my Ideal-Lume Standard light over the weekend and got it setup, I have to say I'm really impressed with the backlighting

I thought these sets shared the same light engine)

Regardless of what settings you use...Contrast and Brightness is going to have to be set for your environment.... Most everyone has at least one movie with the THX calibration tool on it, if not just burn a any one of the dozens of available brightness/contrast test images to a photo CD (I also found a few test images designed to help target shadow detail)... Would love to turn the brightness down to 44 but in my environment closer to 50 is the minimum I can get away with, mid-day 52.

I think people should be very cautious when using anyone elses calibration settings. If those settings work for you and make you happy, then great but as several pro ISF calibrators have noted these sets can trick the color sensors. Below is a post form Randy Tomlinson in the Display Calibration forum regarding Samsung LED DLPs (Tomlinson is a pro ISF calibrator, freelance author of several reviews for Home Theater Magazine).



That's picture of a troll in case you are confused...

Honestly, I don't mind a little dissension. After all, look at what president we got stuck with after the majority drank the Kool-Aid. However, in this case, my money is on Lee's settings with some individualized tweaks.

After using his SM settings, and adjusting user settings using the AVS HD disc and the Wall-E calibration menu, I keep coming back to contrast 99 and brightness 46 (at gamma 0). If I switch to gamma -2, I can turn the contrast down some, but then the blacks aren't that good. I've mainly used Dark Knight (chapter when they escort Dent on the lower level route--I think 20) to test my settings. When I used Lee's contrast 75, and brightness 42, things seemed washed out. As I've posted before when viewing OTA with the internal tuner, I can use Lee's user settings but have to turn color down to the high 30s due to blooming reds/oranges.

All-in-all, I think the PQ is better with the new settings.

rmz76 is OK in my books, we have to have at least one Devil's advocate in our little geek circle of friends, maybe he'll be the one to discover the Holy Grail settings for this TV...He just needs to stop confusing the 750 with the 650

As for using calibration material, I don't bother with that stuff, so many variables to consider including my own preferences that I won't even waste my time, as I know that after spending hours getting everything to match up with that BD material, I'm just going to change the settings for the next movie I play. So I'm trying for a happy medium - a one size fits all so to speak.

So far I have Lee's SM settings including Gamma at film, with Movie user settings at 80 contrast, 50 brightness, 0 gamma, 50/50 tint, everything off, SRGB, Warm2, Led low.

Looks fantastic to me for a generic setting for use at low light/night - during the day, I'd just bump up the led to medium or auto.

I think he is seeing what I pointed out... depending on how one uses the service menu. Lee is capable of calibration, he would have given more information as to difficulties with accuracy. Lee did say that he is having trouble correcting the Red, but nailed down Blue and Green.

Depending on knowledge and Service Menu usage, one may never know any better.

The more you go in and out of service menu (by power off) the more chances as to quirky settings.

Yes, my 2010 Panasonic 42C2 performs better than an S2 No floating blacks and keeps the lowest black levels.

I think at this point you have ZERO credibility in this thread. You posted a quote from a review of the 650 series Samsung claiming it was for the 750 series, and you have yet to acknowledge your mistake. At this point, nothing you write here should be taken seriously as you seem to be pursuing some strange, ulterior motive.

Thanks for sharing though. It does keep things interesting.

Well, my issues with rmz76 involve his behavior and attitude in multiple threads now. I see what you are saying, but he has gone out of his way to do nothing more than stir the pot on several occasions in multiple threads. I could understand it if he was working in a constructive manner with the rest of us to make improvement, but that doesn't appear to be his primary objective.

Well he did post his settings..


My mom works for Sony, and she brought home a copy of "Starhawk BETA"
I quickly slipped it into my trusty PS3, and started playing.

To be honest, it hasn't always been... I'll work on that.

If you're referring to Randy Thomlinson's review, it was not for 650 series bulb sets, it was for a previous generation Samsung LED DLP, his comments about being extremely cautious about using a color analyzer tools applies to the current xa750 series as well. He did provide his phone number if you want to call and chat with him.

Here is a link to his original post.
