Burn Concern - High Contrast Ratio

post #1 of 5
Thread Starter 
TV Model: Samsung PN50C550

I got the Spyder3TV and ran it last night. The room is dim but not totally dark, I know the spyder3Tv will vary from product to product as well as setting from display to display and room to room. The settings below are what I got. It does look good but I am concerned with the high contrast ratio - seems almost like torch mode. LOL!
I bumped the cell light up to 20 (from 15) based on what I'd read on here (was suggested on Samsung to turn cell light all the way up) and it does make a difference.
The software does not adjust the white balances, so they weren't adjusted - just left at 25.

So, my question is - will the settings below cause image retention with the contrast and cell light settings being so high? My TV has over 400 hours on it and I use scrolling a lot when I pasuse a movie or game.

IR and burn in are more content related than settings related. You can reduce brightness and contrast to barely watchable levels but if you leave a stationary image on the screen for an extended period (especially when the set is new), you're liable to end up with one or the other.

Okay, so with the cell light being so high and the contrast it will not make this happen easier?

Possibly. Worst case scenario: new TV with contrast and brightness set at or near torch levels and stationary image displayed for hours or days. Might get IR or burn in quicker than if contrast and brightness are reduced. But there is still a good chance you would experience one or the other.

I see....torch mode is all the setting set high and in my case only contrast is witch I may lower it to 92-95 (witch is still very high) and cell light of 18. I never have images staing on the screen for more than 5 mins and I never pause movies or games usually...if I do I either turn off TV or use the scrolling feature.
