Dont set brightness > -5 to 0.
I have set the Contrast to 70 and it is doing great. Caliberated contrast is 66.


BTW, Is your low brightness issue global or only on ADTV?
For me ADTV is no different from any other source.

I am not sure.. other materials are streamed from m PS3 and it has feature like full color , deep color and etc . So brightness seems to be higher on PS3. I feel ADTV has reduced brightness. I even tried to change the HDMI cable , only in vain.

But i have to say brightness increase globally result in greying of blacks , instead of increasing the whites in the picture and over colors. is it normal in Plasma ?

Dont set brightness -5-0 ? Why BLASTO ?

but as you said , increasing the contrast to higher level , even 65% ,results in overall brightness and increased contrast . HD contents looks simply awesome with higher contrast. anyway after break-in i am going to set contrast as you said.

I said, dont keep it greater than -5 to 0 as it results in losing blacks.
You dint notice the '>' probably.

I thought its a direction symbol LOL..

Yes keeping it even slightly above those level result in loosing black . Why is it so ? I mean changing brightness is very different in plasma ?

It is not different. It is not like that in samsung plasmas.
It is like this only in the panasonics.

Having said that, the blackest that the saming can go is probably at 60 levels of the panasonics. In other words, you can say 60 is the norm and the panasonics go below that until 50. It is just numbers end of the day.

IMO, increasing brightness should make blacks more grey even in LCDs. Is it not so? Brightness is for adjusting blacks and contrast is for adjusting whites.

Please do correct me if i am wrong. In my old LCD , the brightness increases the whites more compared to black and over all intensity of the colors . In panny , the brightness makes black -- grey..

Contrast increased whites / colors / black in combination overall .

just my perception . I tried just now with Nvidia Cpanel brightness and it seems to increase the intensity of the the colors , white .

In panny its more of making black into grey , with no increase in intensity of other colors. Just my thought ...

That is what contrast is expected to do. Making lighter areas light and darker areas dark and make the picture pop out.

Brightness is to increase the overall light output of the panel. Means every pixels output more light.

exactly , but instead of increasing the backlight , in panny , the black is changed to grey , without touching other colors or overall intensity of the backlight

@Blasto , Is it ok to run the Scroll Bar to quicken the break-in time ? Also if its about excitation of all cells equally , why cant we simply display a white image with contrast and brightness at around 30% ?

What is a scrollbar? Does the ST30 have a scrollbar?

You can do that with 100% also. The cells will be always on and age most quickly but they wont be 'excersised' (Meaning it wont change state).
Iam not sure of the difference.

I dint see this post earlier.

That is wrong. Are you sure that the other colours are not affected?

Mine increases brightness of all colours including black. Get better shadow details but the blacks suffer which is non negotiable for me. So I dont go beyond 0.

Scrolling bar ..

To remove any image retentions



scrolling bar runs a high contrast bar in loop. why cant it be used for break-in ? I am just curious. BLASTO , also why is everyone going for all gradation colors for break-in , ie aka break-in slides ? If the goal to excite all the cells equally , cant it be done with scrolling bar ?

Ya i think i am pretty sure. Atleast there isnt any visible increase in colors intensity/brightness as far i can see .

I watched a movie two days back and i had hard time getting the details in dark out . increasing brightness made it grey and beyond certain point , there was no change to the level of brightness overall.

Also where can i find updates for st30 ? Indian site is worthless , firmware page is down with errors.

Can't agree more with this; very unlike other leading brands.

Anyway, here is a link to the Asia site that provides a much better overview and more detailed specifications - also for the other running models,

It can be used. Only it is not present inthe VT20. I din't know it exisited in the ST30.

Only shadow details will increase with brightness. If you find the screen dark, check the gamma setting. 2.2+ and S-Curve will be dark. See if changing gamma to 1.8 or 2 helps. Both these will give a brighter picture with better shadow details.

I used scrolling on my 51D550 for 150 hours for breaking in. But the scrolling is quite different in samsung and it covers full screen with white and the blacks move.

gamma setting in service menu ? I dont have extended color setting .. Or am i missing something ?

 

[BLASTO]

gamma setting in service menu ? I dont have extended color setting .. Or am i missing something ?

It is in advanced setting menu of VT20, where you do the white balance.
Is it not there in ST30?

The green cast issue also need to be adjusted only in this advanced menu.

 

[Naveen_Reloaded]

Advanced menu setting is available only in PC connection (From manual book) ST30 lacks ISF settings.

Even if i do change it in PC connection ., i think it will rarely be reflected in other connection and color profiles.

Please correct me if i am wrong . Also is there a way to increase the gamma alone . i think gamma is slightly lower over all.. via service menu or something ?

Oops. Thats a problem.
I think thats why people generally feel ST30 is dim.
VT20 defaults to 2.2. Thats good for movies but not for normal TV stuff in general.

Look for service menu options in the net to figure out.

 

[BLASTO]

Also, without white balance, are you forced to live with the green cast issue also?

 

[Naveen_Reloaded]

I havent come across any green cast , if you are referring to this

added : Taken from another forum while searching for Green cast issue. Sorry for not mentioning it in first place BLASTO




/will look into how to access service menu and change the gamma. anyone knows can give inputs on this ..

But one thing for sure is 50Hz / 1080i materials have serious problem with ST30 . Could be problem with VT30 too.. not sure.

Also if anyone sees a wave like image in movies , make sure you havent set the aspect ratio as "Just" , it widens the both ends of the image giving a curved image. Just today i found it. For a second i thought i got a faulty panel.

"Just" is a intelligent implementation for 4:3 materials. actually 4:3 materials look better with "Just" and looks more even , not that stretched.
