Hello everyone,

Hoping someone can quickly answer this. I'm fairly new to all this. I bought a disney wow blu ray before I found the avs hd 709 (could have saved myself $18) oh well. Anyways I'm trying to configure my new samsung un40eh6000. After reading online a lot of people say to enable super white on the ps3.

When I enable super white my contrast gets all weird like below. Same goes for the disney wow cd, all the stars are visible even at 100% contrast. In order to get reference white or pure white i have to raise my brightness 10-15+ points so that i dont see any bars after 235 which then washes out black.







However, if i leave super white off it just clips it exactly where it needs to be and i adjust my brightness & contrast a few clicks (which seems like the right setting). Is the tv smart enough and just knows to clip everything after reference white & black and to know there shouldnt be anymore information? When super whites off if i just raise my brightness or contrast to the max the lines (hd 709) or stars (wow cd) never even show show up.





So should i leave super white on or off? I did also notice super white makes whites more "white" but when off, white becomes more "grey"

Leave super white on. You DON'T want to clip above 235. Are you just using your eyes or do you got a meter?

Don't ever raise brightness to compensate.

contrast for white. Brightness for black. Thats it.

If I'm reading your post correctly, you're trying to make only the bars up to 235 flash. What you should be doing is making sure that at least the bars up to 235 flash. That's the minimum and if you're over it, no problem. Then you just have to make sure you don't turn up contrast so high that it hurts your eyes or that tinting is introduced. Contrast is less about an exact spot where it's right and more about your desired light output - as long as you stay over the minimum. E.g. on my D7000 I can set contrast at 65 or at 94 or anywhere in-between. 65 produces a very dark image though and 94 is a bit too much for my eyes. If I go higher than 94, pink tinting starts appearing.

Brightness on the other hand has to be accurate. You want the picture as dark as it can get without losing detail. For that your range is usually only 1-2 clicks and you set it after setting contrast.

Adjusting settings according to personal preference is not calibration.

The brightest white level isn't the RIGHT white level either. You want around 35 fL for a flat panel display in a dark room. If you try to set the highest white level, you could end up with 50-90 fL which is so bright it will cause eyestrain in a dark room. You shouldn't be squinting at a bright white screen in a dark room if the white level (Contrast setting) is correct. Setup discs never describe this correctly. Without a meter, you never know how close or how far you are from the 35 fL level you want to be at. All you can do is guess, based on whether you are experiencing eyestrain or not. The first sign of eyestrain is squiting when the screen is very bright... if that's happening, keep reducing Contrast until the squinting stops, even small amounts of squinting will cause eyestrain or even a headache after a couple of hours of viewing. After you get the squinting eliminated, you have to rely on long term vewing... 2 hours or more, to determine whether the image is still too bright. If you view a "normal" movie that isn't especially dark nor especially bright, and you feel like there's a bit of eyestrain after 2 hours or so, reduce Contrast more and try again on the next movie you watch. It could takes weeks to find the right Contrast setting using that method, but without a meter, it's your only option. With a meter, you just display a 100% white pattern and adjust Contrast (and Backlight if it's an LCD panel) until you are in the 35 fL neighborhood and leave it.

The brighter the room, the brighter you want to make the panel. With 1 lamp on, you might want 40 fL. During the day with sunlight coming into the room, you might want 55 fL or even 60-70 fL depending on how bright the light is. Some TVs, especially plasmas, might not even get as bright as 60-70 fL though. Some LCD TVs will produce 100 fL or more at the highest Contrast and Brightness settings.
