    Hi All
    This post is kinda in the twilight zone. Some where in the back of my mind I seem to remember a DTV channel that you could use to calibrate a TV.

    This channel was only "on" at specific times, but worked very well. With all the new Tv's, it sure would be handy. Maybe just wishful thinking.

    As a side note, if you use a DVD player and a calibration disk, how is the DVD player calibrated?

    HD Net (ch 306) used to show a test/calibration pattern on Saturday mornings around 6am. I'm not sure if they still show it.

    The DVR Player doesn't need to be Calibrated as it is Not a Display Device but just delivers a Video Signal to the Display Device which then can be Calibrated to deliver the Picture Quality desired by the User.

    Thats what I thought. The local Frys has a Panasonic DVD player on sale so I went the the Panasonic site to see the specs and one of the features is a full range of the picture controls. I dont know if this is a common feature with DVD players, if so then it seems that you would be calibrating a TV with a uncalibrated DVD.

    If you used that DVD Player then you would need to make sure that all of the Video Controls are set to Default Settings and then you can play your Calibration DVD and Calibrate your Display Device.

    If your DVR and DVD player are both attached to the same TV input, which means you can only calibrate the TV for one or the other, I would calibrate for the DVR and then tweak the Panasonic DVD player using its own calibration controls, if you think it needs it.

    If your DVR and DVD player are attached to separate inputs on your TV, and your TV allows different calibration settings for different inputs, then you can do all your calibration on the TV. No need to use the Panasonic DVD adjustments.

    HDNet used to broadcast a Saturday morning 10-minute test pattern on 306. I haven't seen it for a while, though.

    HD programming is so spotty, I just calibrate my display with a meter, thru my avr, then roll with it. The Oppo, TiVo and HR34 all look fine to me.

    Hi All
    Thanks for all the input.
    Yes it was HDNET, to bad Directv does not provide calibration info on channel one to enhance the DTVHD experience. Great marketing gimmick and there has to be a ton of new tv's just looking for a enhanced DTV picture.

    I think if someone put instruments on the output of the DIRECTV reciever, they might be disappointed in what they see in terms of linearity.

    Hi All
    When you think about it, all you need to do is get the black and white right then color to suit your personal tastes.

    There's a little more to calibrating a TV then that. If you cannot afford to have your TV professionally calibrated I suggest you use a calibration DVD. There are several available (Monster HDTV Calibration Wizard comes to mind) and are quite affordable.

    A friend of mine got a color TV in 1956 (could have been '57 or '58, don't remember exactly). Great big thing with a little bitty screen. Damn thing had so many calibration buttons on the front and back that it was impossible to get a good (decent) color picture and then switch to another channel and get the same decent picture. They ended up using it as a black and white TV. Just too complicated. When I bought my first color TV in ~ '66, we just used the contrast and brightness controls set so low you couldn't see the picture and then gradually raised the contrast and brightness up so that we had a good B&W picture. Then it was simple to adjust the colors. They certainly made quite a leap from that first color TV to my first color TV.

    I think he meant white level and black level (contrast and brightness), then setting color to preference. Thats definitely not a bad method to getting it OK/good, but you really need a test disc to do that properly.

    Hi All
    This is what I meant, I used a poor choice of words. My new tv is a 42 in. Panasonic lcd.

    I borrowed two DVD players, used HDMI hookup and a "THX"calibration disk. The DVD players had not been calibrated and the test results proved it. The onscreen calibration test results was different for each player. So it would seem that its a crap shoot for calibrating.

    I still like the idea of DTV putting a calibration progam on channel one
