Samsung LE-A78x SERIES LED *Part 2*

[XtremeDJW]

I finally took the plunge and bought the 40" model. Oh I'm so excited!

Would I be right if I said that 786 model is the first tier of LED's of Samsung whilst the next one 956 is more matured with significant improvements?

The problem I have with 9 series is that they are only 46 and 55". I am keen on 40" screen size.

Cheers,
John

The 786 and 956 are from the same generation (2nd) with the 956 having added multimedia capabilities (not sure about picture quality).

That would be right, the 8s back to 4-6 tech, and I think the 756 the same spec as the 8 series but is a special from selected dealers although seems to be going for the same but similar but thiner 8 series.

The 786 has the to what I have seen a better picture in shops, looking forward to getting mine next week, Im noth bothered for playing games in it its for watchink TV and films.

In that case which was the 1st LED series of Samsung? Am I missing something?

Cheers.

The F96 series were Samsung's first LED TV's. Not bad at all but the 2nd generation has some improvements. The 7 and 9 series have the same panels.

I'm looking for the average black level during movies. The black level during movies isn't 0 cd/m², like when you display a complete black picture.
Do you know, what I mean?

Sorry, my english isn't so good.

Further delta errors under 30% are far to high, which means in dark scenes, details won't be shown. Is there a chance to improve it?

I like your settings very much, but it would be very nice, when you could solve the problem above.

The errors under 30% could be because the sensor is having troubles with the lack of light. A Delta of 8.2 at 20% isn't too bad, I can probably improve it but that may be at the expense of other areas.

I never really appreciated what all the fuss was about with the "blacks" now I have this TV I see what everyone is on about. The blacks are very black, almost too black. I never noticed this before on my old CRT. How do the blacks on a CRT compare with blacks on a TV such as this. (786)?

Alright. Maybe you can achieve something like this.

You have to scroll down to the greyscale calibration. Delta errors from 20% gray upwards remain under 2.

Could you also post a Color CIE chart with HDMI Black Level set to normal, please?

If i get time later on I might have another go at calibration. Attached is my saved CHC file from the last grayscale calibration. I'm using a consumer grade sensor aswell and I would imagine their using a pro version which can handle the low light conditions far better which would attribute for my poor results below 30.

If your looking for results close to theirs you'd either be better asking them what their settings are or buying a sensor and trying it for yourself.

Don't know if this has been posted before, but to anyone who is having the whining / whistling noise coming out of the TV: there may be a temporary solution.

Plugging in a headphone jack in the side connector of the TV got rid of all the whining.

Apparently this work-around is only useful for those using an external amp and speakers.

There may be different types of noise / whining / whistling with different causes, I don't know that much, I only know this solution works for me. Apparently the whining is caused by some interference on the speaker lines. Plugging in a headphone jack switches the speaker circuitry off by hardware (as opposed to the menu entry "Speakers Off" which only mutes them via software)

I'm still letting Samsung service come in for a repair giving a definitive solution. Anyhow, this work-around helps me out till that moment.

Googlefan.

Hi, not an expert myself, but interested to buy a 46 7 series. Yesterday I was at Bluwater and there was a Samsung demonstration with a representative. I did ask about the changes in regards to 1st and 2nd generation LED. It seems that the 2nd generation is vastly been improved as now every single pixel is got the ability to dim or switch on and off instead of being a section of pixels that were doing the same job. He also confirmed to the best of his knowledge that the series 9 would be exactly the same screen, technology and identical quality as the 7 series. So, it seems that the extra to pay would purely cover the multimedia interactivity of the 9 series. Well, I am now also a little puzzled after I went to Jlewis in bluwater comparing the 46 786 and the 46 686 (same as 656) incidentally side by side and with an HD 007 film on. Could not really spot any difference in black contrasts etc..., actually, it appeared despite all of my efforts to make all the possible adjustments, that the 686 was visibly to my eyes, slightly but very slightly sharper and so all the other normal TV nearby of the very latest models and makes. Well, not sure about this new technology but are there any drawbacks involved at the moment??? I spoke to the salesman and he actually agreed that it is not worth the extra money at the moment as he personally things that he would go for a good normal plain backlit LCD which as I can see, they have improved a lot in the recent times. Will still investigate about the LED in other shops before I go ahead hoping that I can get a chance to make same very good comparisons same as I did yesterday. Please do not get my comparisons seriously as I might be wrong and what I see is not necesseraly what other might see or like. Do your own testings before making a decision.
Regards to all

I've attached my latest grayscale chc file. I've smoothed out the dE so the majority are around, however, there's a slight peak to just over 4 at 40% which I'll need to fix.

They don't have the settings anymore... and i would like to calibrate the TV myself, but i don't know. I also don't have the equipment.

How can i open the file?

See above.
