I have revisited the current-generation Samsung TVs I've calibrated to adjust the CMS and I now employ this technique on all Samsung flat panel calibrations. These latest Samsung panels can provide an image to rival any professional monitor. Thanks to the ISF, the community of independent calibrators and probably influential internet forums like AVS, manufacturers are finally delivering displays that offer accurate image modes in addition to their retina-searing showroom ones. You see, low black levels aren't the only thing needed for a great image! Samsung has added a feature that makes their TVs truly capable of unprecedented image accuracy. The "looking through a window" effect is heightened and the sense of depth and dimension in the image is greater. The net effect is a more realistic color representation. Once I dropped the luminance of green and blue, I had each color within. You can see what needs to be done: the balance must be restored! By using the Custom mode in the Color Space menu, I can adjust each color individually. My initial measurements on this TV showed the luminance levels to be about 20% too high for green and blue while red was almost perfect. By using a luminance calculator, I can input the actual measurements of each color at 75IRE and find out what the luminance should be. That is the third axis that I can now address thanks to Samsung. What the CIE chart doesn't show is the luminance of each color. It's not absolutely perfect but I've never been closer on any other TV. Below is a CIE chart from a 650-series LCD. There is a standard for that as well but most CMS equipped TVs won't allow adjustment of the color luminance independently.

What Samsung allows which is a real plus on a consumer TV, is adjustment of the luminance of each primary. Most TVs with a CMS allow you move the color points to make this happen. This standard is also referred to as Rec 709 which is the HD color space. In layman's terms, you want the three primaries and three secondaries to match the SMPTE standards on the CIE triangle. Thanks to Doug Blackburn, Widescreen Review writer and ISF calibrator, for his research and instruction on the new Samsung CMS.Ī CMS has two major goals: achieving the correct colors and the proper amount of each color. I recently learned a new technique that has allowed me to achieve a high level of color depth and reality. In this article, I'd like to focus on the CMS. With the user menu, I can achieve a nearly perfect calibration in all respects. It's so nice not to have to navigate an arcane service menu to find these adjustments. As mentioned in other articles on this blog, there are also controls for gamma and white balance.

These controls are available on all Samsung 1080p TVs, LCD and plasma, 32 inches and up. There is even a comprehensive color management system (CMS). The user menu boasts the most complete set of adjustments I've seen outside a projector. Samsung's newest flat panel TVs are quickly becoming a reference standard for calibrators.
