Professional TV Calibration Service

tvCalibration is a leading provider of professional ISF calibration services for OLED, QLED and LED televisions in London and throughout the central and southern counties of the UK.

If you have invested in a new TV of any type, bear in mind that the final link in the chain between content producer and viewer is the adherence to global imaging standards.

The importance of this fundamental step is frequently misunderstood or dismissed as superfluous by retailers and manufacturers alike in their combined efforts to sell a display. Yet without calibrating your TV, image fidelity or faithfulness to the original production is lost.

ISF Calibration Process Overview

Have you ever noticed how all the television pictures in large electrical retailers seem to vary substantially in colour and quality, even though they are displaying the same channel? They are normally designed by their manufacturers to render an attractive image under retail lighting conditions and to stand out from the competition. How do you know which, if any, are accurate? “Shop” picture modes frequently use an incorrect white balance (colour temperature), a lower than ideal black level (resulting in crushed shadow detail) and contrast “enhancers” to create an image that helps to sell the TVs in a competitive market. These picture settings will hurt the dynamic range of the image, use an incorrect gamma, and ramp up the colours to neon levels.

Certain Blu-ray discs are readily available such as, Spears & Munsil and Digital Video Essentials, which contain test patterns and real-life material frequently used to adjust the standard controls of brightness, contrast, colour, and sharpness. Although users who are experienced with these calibration discs may well achieve some improvement, most people find the instructions difficult to follow and often struggle to set the controls correctly. Ultimately, they should not be regarded as a substitute for a professional TV calibration service, because white balance controls and colour management systems require accurate instruments to be set properly.

By using a Murideo SIX-G Ultra HD test pattern generator, a high-quality X-Rite i1 Display Pro colorimeter combined with the class-leading CalMAN video calibration software to perform a comprehensive service, all picture modes (ISF Day, ISF night, HDR, Dolby Vision) will be optimally adjusted. You will experience an improvement in picture quality by seeing the image as the director intended, because your display will be calibrated to the same standards that were used in the video creation. Colours will be more natural, and detail will be present that might otherwise have been lost. Most importantly, you will know that your display is performing at its best for your viewing environment.
