HDTV Picture Settings, Help Me Understand!!!?

Q. I have a 26" Vizio VW26L, most of you probably think it's a crappy, small LCD HDTV but it was all I could afford a year ago (sorta regret it now) but alas I'm stuck with it for a while. I've been trying to get the best HD picture I can out of this HDTV so when I get a PS3 on Tuesday and hook it up via HDMI it will look the best it can but I'm not very knowledgeable with some of the settings. Since you don't have my HDTV I know you can't give me the right settings but if you could just give me a place to start, tell me what certain things mean, etc. I'd really appreciate it! Below I'll list all of the picture settings and how the range it.

Backlight (1-100)
Contrast (1-100)
Brightness (1-100)
Sharpness (1-7)
Color (1-100)
Tint (-32-32)
Color Temperature (Cool, Normal, Warm)

ADVANCED SETTINGS:

DNR (Off, Low, Medium, Strong)
Black Level Extender (On, Off)
Peak White Limiter (On, Off)
CTI (Off, Low, Medium, High)
Color Enhancement (On, Off)
Dynamic Contrast (On, Off)
Dynamic Backlight (On, Off)

I really would like to know what each feature means so I can better understand and better calibrate my HDTV. If you have this HDTV tell me your settings, Thank you!

A. OK, so the first batch of controls are WAY more important than the others. I'll breifly cover the others, you'll mostly want them off.

DNR is digital noise reduction - it will attempt to reduce digital noise in a picture. Probably makes as many mistakes as it fixes, I would leave it off, but you probably wouldn't notice either way.

Dynamic Backlight - sounds horrendous, leave this setting off. If you manage to configure your TV correctly, if the backlight adjusts itself dynamically, it will constantly make all the other settings incorrect.

Dynamic Contrast - the same as the dynamic backlight, leave it off.

Color enhancement - hmmmm maybe have it on, personal preference I guess. I'd leave it off.

CTI - Color Transient Intensity. This is described very well anywhere, I would leave it off as you can't be sure what it's doing.

Black Level Extender - This you might want on, but it's a matter of matching it to your source (PS3). I can't remember what the setting on the PS3 is, but there will be something that will tell it to output extended black levels or not. Set to match on both.

Peak White Limiter - I've not heard it refered to as that before, but it sounds similar to the black level extender. There is some sort of option (again, can't remember what it's called on the PS3) about setting the white levels. See if you can make an educated guess as to what would make them match, if you're unsure, turn it off.

So, now to the important ones. It's very hard to say where to start with these controls, as literally all TV's are different. For example, your brightness goes from 1-100, many TVs might start around 50 out of the box, and you adjust a little up or down from there. For my TV, I have a range of 0-40, and the correct brightness setting for me is just 4.

To give you a very VERY rough starting point:

Personally, I would set the Color Temp to normal (or possibly warm).
Keep the sharpness low, but no so low that things look blurry, perhaps 2-3. Leave the Tint where it came, probably 0. Color, hmmm, probably leave that wherever it came, it's very hard to tell without using a calibration filter to be honest. Then set the backlight to where is comfortable level for normal viewing, and then adjust the 2 most important ones - brightness and contrast.

The only way to accurately set these things up, is to get a calibration DVD. You can purchase these quite easily from places like Amazon. A well-known one is DVE (Digital Video Essentials), although perhaps not best for an absolute beginner. If you want a free one, and if you want an HD one that'll work in your shiny new PS3, check this link out:

Just download the file, burn to DVD and get blu-ray compatible HD calibration going.

Failing that, an incredibly rough way to adjust your brightness is to get a black screen on your TV, (make sure contrast is in the middle) turn the brightness ALL the way down, and then start increasing it until you see the blackness start to turn grey. Then, TRY and get a totally white screen, increase your contrast all the way up to max, then start decreasing it until it starts to turn grey.

Hope that helps.

PS3 and vizio trouble?
Q. i recently purchased a 42" vizio lcd hdtv (it is a 1080p). i hooked it up to my ps3 and i would like to know how to change the picture quality on my ps3. i tried going to 1080p in the display settings but there was no change in the picture quality. is there a cable i need to buy or is there something im doing wrong?
All I need to know is-How do I get my games in HD on that television. Do I need to buy the HDMI Television Cable and then do that setting at Display Settings?

A. You need to use an HDMI cable to get a 1080p picture. What connection are you using?

The PS3 automatically chooses the best resolution for the media you are viewing based on your video connection. Are you trying to play a game or watch a movie or what? Provide details on your current setup and what you are viewing on the TV.
