    after buying and returning more than one television i finally wound up with the new LG 37LH20 model.

    it's a step up in size from the 32 inch i had but is 720 and not 1080. the picture is fine for me but my question is this:

    it has a calibration program sort of like avia or video essentials but not as detailed. my concern is after i calibrate it the contrast setting is up around 90. the back light is at 50 and the others according to the calibration program are close to the middle.

    as i said the picture is fine but i'm concerned about the contrast being set so high at 90. is that normal?

    i have the avia calibration disk and will try it this weekend and do a comparison test.

    thanks,

    william

    Sounds fine to me. There are two ways of controlling the overall light output of the set--increasing or decreasing the backlight brightness and increasing or decreasing the contrast setting. A dimmer backlight setting of about 50 enhances the contrast ratio--less light for the pixels to block when they're supposed to be black. The high contrast setting is giving you truer whites, and on an lcd set will cause no burn-in or premature dimming as it might with a phosphor based (plasma or crt) display.

    The contrast should be up as high as possible without clipping of the white signal. At that point you can consider lowering a bit if eye fatigue develops.

    Depending on the black light....leave the contrast up and adjust the backlight for eye fatigue and daytime vs night time viewing.
