I unlocked those in the service menu but I noticed that the black tone and dynamic contrast doesnt work in those 2 modes, is this normal or do i have to turn something else on. I hope you guys dont get mad at me asking you this, its just that I remember reading how a professional calibrator turned on these modes for someone. A friend of mine is going to let me borrow his equiptment so I'm gonna give it a try and calibrate my tv.
thanks for any help it is greatly appriciated

Black tone crushes shadow detail and dynamic contrast completely screws with gamma, black level and white level. Why the heck would you ever use those controls? Asking this question is a pretty big red flag that you aren't ready to be calibrating anything -- or messing around in a service menu. I don't mean to be nasty about this, just realistic. In general, people who understand the lameness of various "enhancement" controls have been paying more attention to the basics of video display design and use of controls. I'm rather surprised that someone who doesn't understand the function of black tone and dynamic contrast would be even considering entering a service menu or calibration. Again - no offense intended, it simply sounds like you are pushing the envelope quite a bit and that usually ends badly.

I'm sorry you got the wrong idea or I explained it wrong, I dont use black tone or dynamic contrast never never never. I asked because in the cal-night and cal-day they dont work and I was worried that they are automatically on like in dynamic mode. I didnt take offense and I can fully understand where you are coming from especially if I'm going to try a calibration using dynamic contrast:eek: I would yell at me too;)

Now I apologize to you because looking back at my post I can see where I should've explained it better, my bad. I was worried since they dont work that they are on and cannot be turned off. That would make those 2 features totally useless, thats what I meant to ask

OK - that makes more sense... the Day/Night modes (thankfully) disable a lot of the "crap" "image enhancement" stuff - you still have to remember to keep the others that are still available turned off, of course. But some of the worst offenders are turned off when you select a Day/Night mode.

Whew - you had me worried there for a second LOL!

Thanks Doug and I'm glad that it disables them and not leave them automatically on. I have one more question for ya Doug since I got your attention:D In your opinion is the B450 worth getting it professionally calibrated. I ask because since it doesnt have a CMS and the one in the SM supposedly isn't worth a damn. Ok I know a home non professional calabra doesnt hold anything compared to a professional one but would it help on a B450. Is The cost= to the finished product.
thanks once again for taking the time to answer my question Doug, i really appriciate it

Nobody can answer the "is it worth calibration?" question for you.

There's a certain satisfaction in knowing your TV is as good as it can be - for some people, that's worth paying for. For others, not so much.

I haven't seen a TV yet that didn't look better after calibration (unless it got a horrible calibration - or a "fake" calibration from someone with a DVD and no tools).

How much that is worth to somebody is a question only the individual can answer.

I charge extra for TVs with CMS since that almost always just about doubles the time needed for the calibration -- so if you don't have CMS, you'll be getting a "bargain" calibration price anyway.

Teaching yourself how to calibrate and purchasing a meter that will give results without detectable errors almost always costs more than a pro calibration (and takes 100 hours or more of study and practice). Those who learn calibration just for the sake of learning something new, knowing in advance they are going to spend more money than the cost of a pro calibration - and invest a lot of time in the process, often have happy outcomes. Those who look at self-calibration as way to save money (unless there are multiple displays that need re-calibration often) are often frustrated that they end up spending more than they intended... or that they finally give up and pay for a pro calibration.

thanks for taking the time to respond Doug I appricite it, I got my 1st pc after 2000 and within a few months of reading about them on forums I decided to build my own and what agreat feeling that was, a few years ago a friend of mine in the music business needed someone to make his cd covers, so i got photoshop and proceded to teach myself and now am quite good at it. I got my 1st hd tv last november found this great site here and after reading threw these forums everyday decided it might be neat to learn how to calibrate my tv. I love to learn new things and am so appriciative to have found this site with people like yourself here to spread your knowledge and to help us better understand what we are trying to learn, thnak you so very much:) I really want to do it myself but am thinking I might want to have it done professionally just so I can watch and get a better idea of things and then do it myself on my next tv

Greetings

If you want to go the pro route and sit and watch, you need to pick carefully which calibrator you get. Many do the hit and run calibration. They come in and do it ... and leave. This leaves very little time for any education of the client in the calibration process.

As a learning experience ... it is rather useless.

You will need to find a calibrator that also routinely educates while he calibrates. Most of the calibrators that hang out at these sites are attuned to the education track as well.

The need for educating the client is pounded into the heads of THX Video Calibrators when they take the class. It is as important if not more important than the calibration of the TV itself.
