Projector and TV Calibration

The Showroom & Factory Floor Dilemma


TVs are calibrated for the show-floor. The brighter and more saturated they are, the more they will stand out next to other displays from other manufacturers. Unfortunately, to achieve this, manufacturers increase blue light output and turn up saturation to a point where subtle shades of colour will disappear.

Most people will take their expensive TVs home thinking they are getting a great and accurate image, but most often that isn’t the case. If you have just spent thousands on a new TV, you are certainly not getting the most out of your equipment.


While most projectors come out of factories without the colour fine-tuned correctly to HDTV and more recently UHD standards.

What’s more, projectors require a re-calibration every 500 – 700 hours to ensure an accurate image. This is because the colour output of the lamp – and even lasers – shift as they age!

Why Should You Care?

We at Simple Home Cinema believe having the best picture and sound at home is not dependent on budget, but dependent on getting the best equipment your money can buy and setting it up in a way that delivers accurate picture and accurate sound as the director and the broadcasters intended. Unfortunately, most displays and sound equipment you buy today has been calibrated to look and sound best on the show-room floor, not in your home.

As an example, this means that 95% of TVs have an inaccurate colour push towards the blue spectrum in a way that’s not correctable by eye. It results in subtle shades of other colours to be muted. The only way to get around this is to have the display calibrated for both gamut and grayscale.

Below is an example of a display that has been calibrated:

On the left is the uncalibrated image. Notice the blue jacket and the blue reflection of the light on the hair and faces. On the right is the calibrated image. Notice the different shades of blue on the jacket as well as the subtle shades of green being brought back in the image. The blue jacket is now a different shade of blue than the reflection of the fluorescent light on the window. Previously the two were the same. We can also see that the room is bathed in green and not blue in the original program material.

How To Get an Accurate Image?

The only way to get an accurate image is to do a colour and gamma calibration of the display. This requires accurate colour probes (colorimeter) pointed at the screen and software that helps tune the image to reach the correct colour standards as defined for HDTV and UHDTV content. To do this, we go through 3 different calibrations:


Grayscale Calibration

Grayscale calibration ensures that colours on the screen are displayed with the correct mix of green, blue and red. This allows subtle shades of colours  to have the right colouring. When a display has too much blue for example, things that should be grey will look slightly blue and even subtle shades of green and red can change colour, skin tones starting to look a little yellowish. This isn’t so obvious until it is cleared up.


Colour Gamut Calibration

Colour Gamut Calibration ensures the correct intensity of colours on the screen. HD (like Blu Ray and Netflix) has a different gamut than UHD (4K) and a different gamut from SD (like DVDs). Displaying images with the incorrect gamut will result in colours being too deep or too faded and can make skin colour too rosy or too pale.


Gamma Calibration

Gamma calibration ensures that you dark areas and light areas of the picture have the right amount of detail. It also ensures that you can watch darker movies during the day when dark parts of the image may lose detail.

How Can We Help?

We will come to your home to calibrate the image accurately for the following modes as required by you:


Night Mode HD / UHD

A night mode that ensures you see the best contrast and studio-accurate picture with the lights off for those evening movies or TV shows.


Day Mode – HD / UHD

A day mode that ensures you can still enjoy your favourite shows during the day. Using the same mode you use for nights during the day can end up washing out the image or having dark parts of the image wash together losing critical detail. This happens with both TVs and projectors.

cinema3D Mode

If your display has a 3D mode, we can optionally help you fine-tune it and even colour-calibrate it if your display allows. The glasses you wear for 3D introduce a colour tint that needs to be
