SEE YOUR CONTENT, NOT YOUR PANELS

PureTone eliminates unsightly colour casts in your greyscale for balanced, neutral output. It is exclusive to Brompton R2-based panels that have been calibrated with Dynamic Calibration.

It is common for many panel types to show a colour cast in darker greys or when using the panels at low brightness levels. Most content has dark and light areas, so this is a real problem that means you may not get accurate colours and true neutral greys.

It is also a common reason why panels that appear to be matched when displaying full brightness test patterns are obviously unmatched when displaying real content with darker areas.

TRUE NEUTRALS

LEDs and their driver chips are not perfectly linear, meaning that when asked to output a particular brightness they may not accurately achieve it.

Red, green and blue LEDs often have different non-linearities, which can lead to colour casts in greyscales.

PureTone builds on Brompton’s Dynamic Calibration technology to enable each panel type to be profiled. It can then compensate for the non-linearities ensuring true, clean, accurate colours and neutral greys at all brightnesses.

DARK MAGIC

PureTone depends on Dark Magic for additional effective bit depth in order to make very small fractional adjustments to the output drive levels.

Dark Magic improves the quality of the image or video showing on LED panels when they are operating at less than maximum brightness.

FINESSING FOR FILM

PureTone is especially useful for film and broadcast work, where screens are often run at much lower brightness to match camera exposures, and maintaining neutral colour output is critical to looking good on camera.
