SO I got into my service menus

[Rowdy S13]

Ok well I was playing around and got in my service menus last night. I have a few questions though. The main one is are the settings for each input? or are they for them all? Also what is overscan, DNIe, CCA? Lastly I turned the Gamma down to 0 BUT there is another Gamma setting, should I turn that one down as well?

Thanks,
Sean

Playing around in the service menu can render your TV inoperable so be careful.

I can't tell you what values to set but I do know what some of those terms mean:
1. Overscan - The TV always paints more lines than are visible on the screen. This is so that the image fills the entire screen and you don't see a visible black border around the image. Normally you wouldn't change that but too much overscan can make it near impossible to get 1:1 pixel mapping if you were using your computer as the source.

In some cases, if the overscan is too great a small amount of the image gets cropped and that is why the service menu includes an adjustment.

2. DNIe - Samsung's 'noise reduction' feature.

3. CCA - never heard of it and can't guess what the acronym stands for.

4. Gamma is used to adjust the color balance when trying to get the grayscale correct. Mess it up and the TV will look horrible.

I would suggest trying to find more information, maybe at AVSForum, from people who know a bit about service menu adjustments before you dive in and start changing things.

Well the AVS forums is where I got my info thus far. I was just wondering WHY they say to do that. All the settings on my TV were recomended by someone on there whos ISF certified and seemes to be the go to guy. I did read that the overscan was more for HTPC users, and since I use my TV for my PC that was probably a good thing. I also want to add that I only changed the things I listed, I didnt "play" with it. It was scarry in those menus. So far this is how I have it set up (This seemes to be the starting point before running a Avia set up DVD)
CCA: off (Service menu)
Overscan: off (service menu)
DNIe: off (service menu, and user menu)
Gamma: 0 (service menu)
Digital NR: off (user menu)
Mode: Movie
Contrast: 40
Brightness: 45
Sharpness: 0
Color: 45
Tint: G50/R50
Color Tone: Warm 2

Thanks,

Sorry, nope. Service menu is for the pros out there. experiment at your peril. You need proper gear to color balance it, etc.
You can do a pretty good job with a test DVD and the user menus.
And, if picture quality is that important, find an ISF calibrator.

Thanks for the response. The reason for what Ive adjusted is because an ISF tech has recomended that ALL samsung 1080p DLP should start with those settings in the service menu to get a better base grayscale. Its not gonna be the same as an ISF calibration, but better than normal Avia adjustments. I can tell you that it looks a million times better with those few settings. I do have a more basic question though. I was wondering How in the Hell do you adjust the color on othe inputs? On my TV each input (even each antenna) saves its own different settings. How would you get the test patterns from say an Avia disc onto these? It seems that they should be different than a movie setting beacuse the movie settings are dark.

I tried the basic "movie" settings for TV, and it was way to dark for me. Also I watch movies in the dark, but TV with lights on. So that affects it, right? Thanks for youre help guys.

I am not aware of a movie setting for a TV, only the standard calibration and wherever that leads to.
So, you may need to send the DVD signals to the TV on the other video connections.
