Default setting contrast

Is it damaging for the lcd display to level the contrast setting up till 90 out of 100. For my 40Z5500 it is the factorysetting but I remember to read something about never to push it over 60%. In the days of CRT it was damaging.

Damaging to your eyes, and possibly shortening the life of your display.

The Spears and Munsil calibration disc deals with correct contrast setting better than any I've seen. One came with my Oppo BD-83 but I understand they are sold separately.

You can't actually do a LCD set any harm or shorten its life by having contrast set too high.

However, if it is higher than necessary, you will lose definition with bright content.

Aside from using a calibration disc to determine the maximum contrast setting at which you do not "crush" the whites, the best thing is to simply adjust contrast for comfortable viewing based on program content and ambient lighting conditions.

In vivid mode....

Great display and if you wish, use the movie/cinema mode - warm 2 color temp setting. Give your eyeballs a chance to react to this very very close to accurate setting and throw in a film.

If the room is quite bright, try the standard setting as it is "in between" vivid and cinema.

You will notice that the contrast and brightness controls are different than the vivid setting by a good margin.

Again, you have one of Sony's best kept little secrets there. I tested several of the Z4100's and found them to be very nearly perfect in many ways, right out of the box just by using the color temp 2 and movie mode. Hopefully Sony did nothing to alter this with a "newer" model.

You cannot, as Scottnot said, hurt anything but your retinas and pocketbook (electricity use) by leaving it in vivid.

Thank you for your reactions.

I use the cinema settings. Contrast is set at 90 at factorysetting in that mode. I did lower the backlight from 5 to 4. I understand that the lower the better for the lifespan of the television.

Is there a relation between the level of backlight and the height of the contrastsettings?

The picture looks very good when playing Blu-rays. But also normal DVD's (576p) look fantastic because of the Bravia 3 engine. Better than letting the PS3 do the upscaling( 1080p). To me anyway.

I leave it at factorysettings than.
