Q. TV is 4 years old & was calibrated 2 yrs ago. Is the color supposed to be calibrated every couple years? Our TV salesperson says after a couple years, it doesn't make much difference & I don't know why he'd think that considering they charge $300!
It is flat screen not rear projection. My husband swears they need to be calibrated every couple years and we don't know how to do it ourselves.

A. Back when CRT-based TV’s, monitors, and projectors were the only game in town—and consumer display calibration was beginning to take roots within a niche market comprised primarily of videophiles and ardent video enthusiasts—it was recommended that such displays be recalibrated annually for those that wanted to maintain the highest level of color accuracy possible. But that was back when the overwhelming majority of consumer electronics manufacturers universally dismissed or ignored color accuracy…regularly producing TV’s and RPTV’s pre-set from the factory to produce a noticeably bluer gray-scale, which is typically perceived as brighter and more vivid.
Once more and more consumers were exposed to greater color accuracy and improved picture fidelity, thanks in large part to the efforts of Joe Kane and the Imaging Science Foundation, and further promoted by the media, most manufacturers of today’s consumer display devices now regularly provide one or more factory settings in addition to a variety of user-accessible picture controls that offer substantially better color accuracy and image fidelity directly out of the box. Without question, professional display calibration is far from a necessity for most consumers; only die-hard enthusiasts and videophiles (and opportunistic big-box consumer electronics retailers) believe/claim display “calibration” is a necessity.
From an earlier post* of mine: “I also encourage you to read the online Peter Putnam article, the Secrets of Home Theater and High Fidelity articles, and several of the other applicable resources to which I have provided a links below. In the end you may find that the optimization process is more than sufficient.” If you really feel the need for regular instrument-based professional display calibrations then you should strongly consider purchasing your own tristimulus colorimeter—some selling for roughly the same price as a single display calibration from Best Buy’s Geek Squad—and performing your own display “calibrations” at your leisure.
The bottom line is this: without a precision calibrated color reference display, placed side-by-side with your display, it is extremely unlikely that you—not unlike the majority of people with normal color vision—will be able to notice if the color accuracy (or gray-scale tracking) of your television is out of tolerance by a small to moderate amount. Quite often careful display configuration and optimization is all one needs to enjoy a sufficiently accurate color picture. And if you still feel the need to pay for a third-party professional display calibration then you should at least receive a significant discount for regular periodic ‘maintenance’ calibrations.

What is the difference between analog RGB and DVI inputs?
Q. You know, to hook up a computer to an LCD? I heard that DVI has a better picture quality but Im not sure. Thanks.
A. DVI does have better quality, but you need a video card that supports it.
RGB is not a typical monitor connection, because it can scale up to a mere 640x480 pixels. I think you may be referring to VGA, however, which has the same resolution limits as DVI (1920x1200).
DVI will yield more accurate colors, though refresh rates and response times won't differ. For a high-end monitor, such as Dell's or HP's 30-inchers, the resolution is 2560x1600. Under these ridonkulous conditions, you must use a dual-link DVI connection—even then, only if you have a compatible video card. Anything under that should only require a standard single-dvi connection.
However, unless you're an amateur graphic artist or beginning professional photographer, DVI won't make a huge difference (I specified skill level because a true professional would have a dual-link DVI setup). I use DVI on my primary 1680x1050 LCD and the gamut is imperciptibly different from my secondary 1280x1024 LCD which is connected via VGA.
In truth, it doesn't matter what you use. If you already have a DVI cord and a DVI capable computer and monitor, then it wouldn't hurt to use it in place of your VGA connection. Inversely, if you don't have a DVI cord or DVI capable set-up, then there is absolutely no rush to go out and buy one because you won't see any performance increase. Both connections put the same load on your computer. To put the quality difference in perspective, if VGA was 96%, then DVI would be 98% (in terms of color accuracy).
