I'm sure there are cases where professional calibration would be worth it. But these guys are saying EVERY tv is inaccurate and needs calibration. Which just is not true from top tv's from pioneer-sony-samsung-panasonic. Sure, it depends on the model.. But not EVERY. A few more reviews.
"As I said earlier, the overall color accuracy of the HL61A750 is exceptional, provided you set it up properly. Grayscale tracking in the Warm 2 color temperature setting is close to the broadcast standard. Primary and secondary color points are quite close to the HDTV specification, and the color decoding is spot on. All of these things combine to give the Samsung the ability to deliver incredibly accurate color, and this is extremely impressive with high-resolution HD sources, like Blu-ray."
"Overall performance on the Sony KD-S55A3000 was excellent, and its standout characteristic compared with other HDTVs is color accuracy. When the Sony is set to Standard color space, the primary colors of red, green, and blue are nearly dead-on accurate to the ATSC specifications. The color decoding is accurate for both SD and HD sources, and the grayscale from the Warm 2 factory preset came mighty close to the broadcast standard. A quick tweak in the advanced menu under white balance made the grayscale nearly perfect. For our full user-menu settings, click here or scroll down to the Tips section below."
"We typically go on and on about calibration but with the TH-50PZ800U we didn't have to do much beyond increasing its contrast control a bit to approach our 40 footlambert baseline light output. Compared with other picture modes and to the company's own TH-46PZ85U, THX on the PZ800U delivered superior color temperature and especially primary color accuracy, and despite the fact that THX mode didn't pass blacker-than-black parts of the video signal (while the Custom mode did), we left brightness alone for optimal performance"
"Panasonic makes a big deal about the Digital Cinema Color on the 850U series, and color is the most noticeable difference between its picture and that of the 800U. The primary and secondary color points of the 800U hew very closely to the HDTV standard, and so its color is technically very accurate, while the color points of the 850U are not. Like many displays, its color gamut is wider than the HD standard, so the red blood in the centrifuge, for example, looks even redder and deeper on the 850U than on the 800U. Greens, such as the forest and shrubs that are visible when the janitorial crew is motored into the compound, looked both greener and seemingly a bit yellower to our eyes on the 850U. We switched off the Digital Cinema Color mode and the two displays came closer to one another, but there was still a pretty noticeable difference. Our measurements for the Geek Box below were taken with the more-accurate (again, compared to the HD standard) Off position for that mode.
An argument can be made that the wider color gamut on the 850 looks better, but that's largely subjective. Our goal, as always, is to evaluate color accuracy, in this case compared with the HD standard, and by that definition the 800U, along with the two Samsung displays in our comparison, were a good deal more accurate than the 850U.
Other areas of the Panasonic's color performance were very good. The 850's relatively linear grayscale was apparent in skin tones, such as Irene's face at the beach house, appeared natural if a tiny bit redder than the reference 800U. Color decoding wasn't at fault--it was basically right on; instead it was the very slightly reddish grayscale in mid-dark areas. Colors near black stayed quite accurate otherwise, however."
"The Samsung LN52A650 is one of the best-performing LCDs we've tested. Its picture quality, anchored by excellent black-level performance, and accurate color, surpasses that of the Sony KDL-46XBR4--and Samsung's de-judder video processing has improved to the point where it's basically equal to the Sony. We did notice a couple of minor issues, and as usual we'd avoid watching dark movies on this glossy-screened TV in rooms with lots of ambient light, but that's about it.
Our standard calibration was aided by the numerous picture controls in the Samsung's user menu. We were able to improve color temperature and dial in saturation without going overboard thanks to the blue-only mode (check this tip to see how it works). Although we attempted to tweak the color points a bit using the custom color palette controls, primary and secondary colors were already close enough to the standard that we simply settled on the default Auto in the end."
