Best Picture Quality

In most cases, 75% contrast, 40 to 50% brightness and 35 to 45% color will be best. Adjust the picture sharpness control in between 10 and 25%

I have samsung TV 40 inches flat screen comes on the picture ok but within 10 minutes the picture goes black and white

Does it look like a dim black swirling cloud with very faint images?

hi can i just add? I have recently got this tv but for some reason when i set setting to Normal they reset to dynamic?? After about twenty mins? I keep having to change back to normal or if i set it to perfect brightness etc... it just goes back to dynamic again? i.e cell light 100% and contrast up to 100%!

Why is this??

Best is kind of subjective since each person's eyes are different. If you are looking for a bright and vivid picture, you can go to the picture mode and change it to that setting. Usually it is called something like "Vivid" or "Dynamic." Besides that, it is all user preference. Most people prefer to just use the factory default settings.

I think I have a solution involving far less effort. Have you tuned your picture settings? Out of the box, the settings are ok and the presets will do the trick for most. But if you're like myself, you want the best picture possible. Here are my settings:

HDMI cables are the best you can get right now as long as all your components have HDMI connections. Just don't overpay. Order them online and you'll be able to find them for less than $20 each. Walk into a store and you'll get jacked for $75 or more.

edge enhancement option i think would be enabled if you are in dynamic or movie mode. What it does is to enhance the contrast of the edges of 2 different colors.

I have the LA32S8, similar specs but only 7000:1 CONTRAST ratio. when playing dvd, i set it to movie mode. Settings vary on different tv and player. you can adjust first the backlight, then brightness then contrast, color and sharpness. the brightness you adjust by choosing the level that shows enough details on dark scenes. adjust if its too dark not to see the details of the scene. contrast, you can set by distiguishing vivid colors of the picture, dont put too much contrast as your picture would look flat. it should have a 3d look, same also with sharpness, you can experiment on the face of a person to show details on the edges.
color you set just enough to make it accurate on color reproduction.

My settings for movie are
contrast 92
brightness 49
sharpness 23
color 57
tint g48 r52
backlight 7
tone warm1
digital NR off
black adjust high
dynamic ocntrast high
gamma +2
