ISF Calibration (Professional TV Calibration Service)

ISF Calibration (Professional TV Calibration Service)

We provide professional ISF calibration services for OLED, QLED, LED televisions and digital projectors throughout the UK mainland.

If you have invested in a new display for your home cinema, bear in mind that the final link in the chain between filmmaker and viewer is to calibrate your TV.

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 new TV. Yet without calibrating your TV for the best picture, image fidelity or faithfulness to the original production is lost.

ISF-Certified 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? A “Shop” picture mode will frequently use an incorrect 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 TV 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-end Colorimetry Research CR-100 colorimeter combined with the class-leading CalMAN video calibration software to perform a comprehensive service, all picture modes (ISF Day, ISF night, game, 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.

Service Pricing

Our prices start at £300 for a single TV or projector. Discounted rates are available for more than one display calibrated on the same day.

Frequently Asked Questions

1. Should my new TV be broken-in first?
We recommend using a new display for at least one week before arranging an appointment for a calibration.

2. Will professional calibration void my manufacturer’s warranty?
Not at all. Current displays have all the necessary picture controls available in the user menus. None of these adjustments will adversely affect your warranty.

3. What if I were to factory reset the TV due to a problem?
We will send you a copy of all the calibrated settings for the changes we make so that you can re-input them yourself in case of such a problem.

4. How long does a video calibration take?
Normally, between two and four hours depending on the television or projector model and number of picture modes needed.

5. Is a dark room necessary?
For televisions, normal household curtains or blinds will be sufficient. Projectors need complete darkness as any stray light will adversely affect the results.
