This thread is to document the black level measurements of the various displays that I have measured black levels in Malaysia/Singapore or anywhere in Asia

My equipment:

For the purposes of black level measurements I will use the following

1. X-Rite Chroma 5E
Specs : 0.02cd/m2 - 1000cd/m2
(0.006ft/L - 291ft/L)

2. Klein K-10
Measurement Range:
0.00006-2919 fL; 0.0002-10,000 cd/m2

cd/m2 - Candela/meter2
ft/L - foot Lamberts

I also own a EyeOne Pro Spectrophotometer that is used for calibration but not suitable for black level measurements.

The lower the number indicates lower black levels (better). These measurements are for a full/window black 0% IRE signal. As I get ANSI contrast measurements, I will add to this thread.

Plasma

Pioneer 428XG (2000hrs) - 0.009ft/L
Pioneer 428XG (2200hrs) - 0.011ft/L (ANSI Method)
Pioneer 508XG (~3000hrs) - 0.008ft/L
KRP600M (1200hrs) - 0.0013ft/L
KRP600M (1500hrs) - 0.0025ft/L (ANSI Method)

Panasonic 50VT20 (200+hrs) - 0.005ft/L
Panasonic 50V20 (1500hrs) - 0.009ft/L
Panasonic 50U20 (1200hrs) - 0.024ft/L
Panasonic 42X10 (2000hrs) - 0.08ft/L
Panasonic 42U30 (500hrs) - 0.032ft/L

Panasonic 65VT50 - 0.0025ft/L (THX Modes)
- 0.0033ft/L (ANSI - THX Mode)
- 0.006ft/L (Pro Modes)
- 0.006ft/L (ANSI - ProMode)
Panasonic 65ST50 - 0.0028ft/L (TrueCinema Mode)
- 0.0033ft/L (ANSI)

Samsung 50C650 ~500hrs - 0.06ft/L (0.12ft/L with Cinema Smooth on)

Edit: Added xx50 measurements

Rising Black....

The 2010 models did rise a bit after 1000hrs. And 1 more rise at about 2000hrs or so.

This thread will not answer which is better (LCD or plasma) as this is only one part of the puzzle.

Brightness? I am assuming you mean contrast (how bright does a white screen go)?

I have seen plasmas go as high as 50ft/L for a window of 100% white while still maintaining good integrity of white. If its a full screen of 100% white, then the 9G Kuros could go to about 18ft/L. I am told that this years Panasonics can go up to 24ft/L (which is bright in my opinion).

LCDs are different as they do not have the ABL (Automatic Brightness Limiter) or APL (Automatic Peak Limiter) that the plasmas have. The highest contrast I could get a LCD to go while maintining integrity of white was about 40ft/L (I believe the new LGs, Samsung and Sony could go higher ~55ft/L but I have not measured them as yet). The difference is that LCDs that show 40ft/L on windows will show 40ft/L on full screen as well, so LCDs do go brighter (full white) in real life. While it is not necessary to go that high for dim/dark environment and will be uncomfortable to the eye those circumstances, it is good for bright environments....

Posting a picture will not really help, as the monitor that different people use to view it are not calibrated so it will be different.

In real life, 30ft/L of windowed white is plenty bright in a dim environment and 45ft/L windowed white is bright enuf for day environment if ur screen is matte or has a good anti reflective coating.

Great thread! This will be very helpful for those potential TV buyers and to those concern with rising blacks on their pre 2011 Panny sets.
It also gives a good perception on how actual black level readings look like. Thanks AD!
Hope it becomes sticky.

@anfieldude

So you finally got your K-10... enjoy smile.gif

What's your guesstimate of V20 final stable black level? You think Panny finally resolved the rising black in 2011 panels? Alot of speculation now...

Yeah, got my K-10 about 1 month ago. Fantastic piece of equipment. Very stable readings all around. Profiled with the EyeOne Pro it becomes quite a tool for calibration.

I can finally measure black levels on the 9G Kuros and its that low.

I believe the V20 shd be in the range of 0.01 - 0.02 ft/L, will add info as I get them.

Panasonic 50U20 (1200hrs) - 0.024ft/L
Panasonic 42X10 (2000hrs) - 0.08ft/L

Samsung C650 ~500hrs - 0.02ft/L (0.067ft/L with Cinema Smooth on)

the panny V20 at 1500hrs-.009ft/L is still pretty impressive but the U20 at 1200hrs - .024ft/L is worrying although the sammy with Cinema Smooth engaged is worst which i have read at Avforum before. rather unfortunately ,at least the 51''D8000 still have issues with little improvement whenever cinema smooth is engaged. it is still a toss of coin whether Panny have solved the issue of floating and rising black for 2011 models although panny have apparently attempted to address it

but for most average Joe any measurement from .015 to .025ft/L is still acceptable and is actually not that bad at all. only the videophiles and enthusiasts may think otherwise.

thanks to AD for starting this thread to keep us here informed and educated as well

I corrected my information on the older C650. Keep in mind that this is an older model. The 2010 models were better.

I hope to add more Samsung measurements when I get the chance. I will also add LCD measurements when I get them.

Does that mean the 50U20 with raising black is still better than the Samsung that has no raising black?

Yes but this was comparing the 2010 Panny with the 2009 Samsung.

Human being are pretty funny animal. They all get so concerned about Panasonic raising black and I am sure some will not buy Panasonic because of this issue. And here you are saying even with the raising black issue, it's still better then the "no complaint about raising black" Samsung. LOL

hi anfieldude,

Many thanks for this and your many excellent postings. Good to see healthy knowledgeable discussion that helped general mortals like us ;-)

Now, am tossing between the VT20 or the upcoming ST30... hoping to see the ST30 opinion/findings soon...

he already said that it's comparing between 2010 pana and 2009 samsung.
do read around about the 2010 samsungs before making your assumption.

because quite frankly, a lot of your posts before this sounded like a plasma and pana fanboy. just because you bought a medium range pana don't make every other tech/maker/model inferior to your pana.

Hi Anfieldude, what is the black level measurement for Pioneer KRP-500 A? Is it comparable to KRP-600M?
