Talk about pedantic. They're all the same

If you think they are all the same maybe we shouldn't even be having this discussion, i don't know why you had to pipe up anyway.

I provided the links that say it all, if you don't want to read them and back down then that's your problem not mine.

And remember, the above first contentious post stated by HaRd2BeAr: "The HX850 and HX750 are both edge lit, the HX850 does have local dimming although edge based. The HX750 dims the light output of the display to create deep blacks the HX850 can dim sections of the screen.
Don't bother getting pedantic with me thanks. "It's edge lit its not true local dimming" is WRONG.

Yes they are both edge lit, but the HX750 upon detecting a dark scene, dims the entire screen to reproduce black images, the HX850 dims sections of the screen, they are not "all the same". Read reviews of the HX750 and HX850, the difference come across in the reviews. The HX750 is not as affective at reproducing dark scenes as the HX850.

CLEARLY YOU DON'T UNDERSTAND THIS. PLEASE CALL SONY.

GET IT? DYNAMIC edge lighting as opposed to EDGE lifting on the EX series.

because I "piped" up since you were giving out incorrect information. Your major issue is inability to read specs. All HX models provide the same dynamic edge lighting. The differences are Motionflow rates and Gorilla Glass. Your first post about this was confused and totally wrong. So, you think we shouldn't be having this discussion because you are correct, which you are not.

Sony have simplified their local dimming techniques this year and it’s certainly better than last year’s mediocre attempts.

On the face of it that doesn’t sound very many but as the dimming works from both left and right sides, you can effectively double that number. Which is still not very many compared to around 2 million ‘local zones’ employed in a 1080p plasma display but the proof of the pudding is in the eating and we were happy to have it on its highest setting of Standard that gave a better depth to blacks whilst not producing a bright glow around objects on a dark background, more a faint milkiness. With the LED Dynamic Control set at standard, we took a measurement of 0.052cd/m2 from an ANSI Checkerboard pattern with our Klein K-10. It’s no competition for the 2012 Panasonic plasmas but we weren’t expecting it to be and the generally excellent uniformity and clear shadow detailing set it apart from most other LED TVs that can reach comparable levels of blackness. Of course, we don’t want the black level measurement to be taken as definitive but it was taken with the same equipment, under the same conditions as the 65ST50 and 42GT50 and using the same software. Shadow detailing is marginally compromised when eye-level isn’t above the centre of the screen, which is just about the only impact we found with the angle at which the HX853 rests against the stand.

Black levels were very decent with the 753 measuring at 0.052cd/m2 on an ANSI checkerboard pattern which is almost exactly what we noted with the 55HX853, using the same Klein K-10 meter, in the same conditions so contrast levels are good and hold up well in bright conditions owing to the use of a very effective filter. As a point of interest, engaging the Adv Contrast Enhancer didn’t really make a difference to the measurements.

Though the black level is impressive, the sample supplied did suffer with some clouding problems that intruded with darker scenes, although this could be improved by utilising the control labelled Adv Contrast Enhancer. This is, in reality, the global dimming control where Low is actually the most aggressive setting, rather confusingly. Users will need to balance the use of the control with the fact that it will lose detail in very dark scenes owing to the imprecision of the system; in a perfect world we would prefer not to have used it but given the clouding issues it was preferable to lose a bit of detail rather than suffer unduly with them.

I really wanted to avoid replying and imbroiling myself in this. You are looking under "Overview". I went to your links and instead of looking under "Overview" I just happened to look under "Features". Under "Features" a distinction is noted between the HX750 and the HX850 and I quoted *verbatim*- see above.. Sony should clean up their pages.

You are still incorrect stating that the 750 does not have dynamic edge lit local dimming. Section 2 is about the Motionflow rates which we all know and really the difference between 480 and 960 would be very hard to see. You were not civil from the start. I doubt you would be so condescending face to face rather than hiding behind your computer. If there is a difference between the 750 and 850, it's not on the Sony site. You just insist on nattering on and on that the 750 doesn't have dynamic edge lit local dimming which is does as does the 729 and 820 version from last year. Your first incorrect post flat out stated that the 750 had regular edge lighting, which was wrong. If you stated that the dynamic edge lighting was improved for the 2012 models, I might have given it thought but you started out not even stating the facts correctly. Plus smug. I know 2nd tier product specialists at Sony and will get the facts not based on reviews here but from Sony directly.

Is that all you are disagreeing with?

They are both Dynamic Edge LED Sony tvs, but the HX750 has a far more basic dimming control than the HX850.

Sorry if that was where i confused things.

Didn't mean to come across in a bad way, having a bad week.

I will word things more appropriately in future.

Aaron,

Unfortunately things get heated up which is ridiculous. Sony as well could be at fault for posting the following at Sony Style for the 750:
Quote:
It's all about perfecting a natural look. Dynamic Edge LED backlighting with frame dimming delivers pitch-black night scenes and illuminates bright scenes that pop with vibrant color. Rather than illuminating the entire screen, contrast is boosted in just the right areas for a more realistic picture./QUOTE]

No harm meant either from me. I want to speak to SONY (not a tier 1 person) tomorrow when I ask about a recent firmware update. You very well may be right but I'm curious how they explain it.

Regards,
Steve

PS: I'm having trouble separating quotes from the rest of this reply.

When initially posting HX750 spec's I listed this model as having Guerrilla Glass. After all that was what CNET had written. It wasn't long before someone pointed out Sony.com wrote otherwise. I contacted CNET where upon they asked me for a reference. Of course my response was Sony.

Enjoy your HX's.

Is this a defect or am I just being picky?
Think the user Gatorboi has the same issue.

In dark scenes I see the spotlight/flashlight coming from the bottom left corner.
I have 1.5 weeks left on the 30day return window (replacement program from Sony Listens).

I have not contacted them yet, figured I'd get some advice before proceeding.

Yep. Lower left BY the corner.

I realize edgelit tvs will have some bleeding in its corners which arent so distracting.

My 55HX729 has no bleeding or flash lighting. It has minor, minor clouding watching a black credit roll in a pitch black room. I have rarely watched this TV in total darkness so that's a non-issue. Return that set is my advice.

Most do not exhibit flashlighting or bleeding. Consumers who get this defect do post here and it's not that rare, unfortunately.

I also have a 3 year old KDL-52EX701, one of the early basic edge LED TVs, and it does have light bleeds that are white/blueish top and bottom of the bezel but only seen off angle but they're there. i chose to ignore it because they're not visible viewed straight on.

As for mura or a small amount of clouding viewed on solid black in a blacked out room, it took me 5 months to see it! Clouding is a common anomaly and is an issue if it's excessive or seen during content. That spot on LAefj's set though is a defect.

I just spoke with Sony Tier 2, product specialist, arranged through Sarah Kepler at Sony Listens. The HX729, HX750, and HX850 all share the same Dynamic Edge Lit technology. They're all the same. The HX750 does not have the X Reality Pro Engine as the HX729 and HX850, and XBR929 have. The HX750 has the X Reality Engine.
post #172 of 1878
I was emailed a SONY comparison chart. Dynamic Edge is the LED backlight technology on all models described above.
post #173 of 1878
In last year's models, the 729 and the 829 were virtually identical but for the 829's OptiContrast panel and Gorilla Glass. A consumer, therefore, could get a television with 95+% of the features of the higher priced model without paying the increased premium. Not surprisingly, in the 2012 lineup, Sony took several features away from the 750 in order to properly distinguish it from the 850. Features removed include the X-Reality Pro engine and local dimming.

The 729 is listed under its Features page as having "Dynamic Edge LED backlighting with local dimming."
http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&partNumber=KDL55HX729#features

The 750, in contrast, is listed under its Features page as having "Dynamic Edge LED backlighting with frame dimming."
http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&partNumber=KDL55HX750#features

And, as we can see from Sony's UK site, there is a difference between the two technologies:
http://www.sony.co.uk/hub/lcd-television/benefits/tv-picture-quality/article/led-backlighting

Specifically, "Local-dimming technology independently controls the brightness of individual of LEDs depending on the image showing" whereas "Dynamic Edge LED screen with frame dimming analyses the video signal and adjusts backlight levels in each frame in the right part of the screen." The fact that Sony dedicated separate paragraphs to each technology is a clear indication that they are not the same thing. If they were identical, there would be no need to confuse consumers by changing the name of the technology for some models but retaining it for others.

CNet also notes the difference - "The TV features a LED edge-lit panel that we were originally told supported local dimming. That's not the case however; local dimming is only available on the step-up NX850 and HX929 among current Sony models."
http://reviews.cnet.com/flat-panel-tvs/sony-kdl-55hx750/4505-6482_7-35118060.html

In my opinion, it appears that local dimming is not the same thing as frame dimming.

post #178 of 1878
Hey Everyone,

I could use some help/advice. I bought a KDL - 46HX750 a few days ago from Best Buy and am having trouble getting the picture as sharp as I think it should be. The faces up-close are very clear and look great, however, sports and overall picture are just not quite at clear as they should be and even border on grainy sometimes.

I am using an HDMI Cable to connect to my cable box (although the picture looks the same on Netflix and DVDs, so I don' think the cable box is the issue.)

What I've tried so far:

1. Plugging into different power source
2. Watching DVD/Netflix (same sub-par picture)
3. Different levels of noise reduction
4. Different picture ratio (Normal, Wide, Zoom)

I also troubleshooted with a Sony Employee over the phone (though I got the sense he was just reading off a piece of paper what I had tried already.) He told me they would have to come service it - I don't want them to mess with the parts on a 72 hour old TV. I feel like it's gotta be an easy fix??

Any ideas or anyone else come across this issue?

Thanks.
post #179 of 1878
After 4 weeks, my flashlighting seems to have disappeared completely. It was extremely noticeable on a blank (ish) screen but not visible at all now.
post #180 of 1878
Since cable is 720p at best (HD cable I assume), I'm guessing the cable source.

I watch a lot of 1080p. I watch close enough to almost make out the pixels and do lots of pause/freeze framing to take snapshots from VLC player. Sharpness seems OK but you got me looking.

Can you be more specific? fuzzy edges or blurring? Have you tried mkv movies or Bluray and is it the same and were they 720p, 1080p or HD cable?
