What’s the Difference Between Light Tuner and Black eQualizer?

BenQ gaming monitors improve your experiences with a host of smart technologies. Among them are Light Tuner and Black eQualizer, which optimize image balance and prevent the loss of vital details. 

If you’re interested in quality gaming monitors for PC and consoles, you’re likely aware that brightness and contrast remain sometimes thorny issues. With game graphics, it’s often hard to find a balance between light and dark. That’s why literally every game, from the biggest PC mega-technical release through mainstream console titles to mobile ports – well, they all have a gamma or brightness setting within the game. That’s because there’s frequently a disconnect between what the monitor provides and the internal settings of the game as determined by developers. Light Tuner and Black eQualizer aim to remedy any such disconnect.

Too bright or too dark video means overexposed, washed out images or a major loss of detail. Basic brightness or gamma adjustments within the game may help, but rarely provide a consistent fix. That’s where your smart gaming monitor steps in. Advanced technology offers reactive algorithms that constantly scan image input and correct overly darkened or extremely bright areas of the screen and balance them to prevent detail loss, crushed blacks, and overexposure. Theoretically, one all-encompassing function could cover all of that, but BenQ engineers find that having dedicated routines for contrast and brightness works far better, while incurring essentially no added delay or latency. 

Light Tuner and Black eQualizer function very similarly to modern anti-aliasing and anisotropic filtering in that they always look at screen output and kick in whenever their logic determines an adjustment needs to be made. Of course, you can always turn them off in the OSD if you prefer your display “as is”. If an image doesn’t outwardly call for correction, both functions will hold off. Also, both have degrees of intervention rather than just one setting, so they’ll modify an image intelligently instead of providing a one fits all approach. 

Black eQualizer’s logic also reflects its naming. Here we have a technology that looks at areas of the screen that are meant to be dark, but turn out overly darkened when finally rendered. In a sense, this is the opposite of Light Tuner, but the net result is similar. Light Tuner reclaims details from improperly depicted bright areas, while Black eQualizer does essentially the same for incorrectly shown dark sections.

While Light Tuner works best in story-rich games, Black eQualizer hails from an esports lineage and is therefore most suited to high speed first person actioners like Call of Duty or intense survival shooters such as Escape from Tarkov. The primary benefit of Black eQualizer is spotting opponents and dangers hidden by crushed black levels or overly dark rendering. Importantly, Black eQualizer adjusts these areas to their correct values without disturbing the overall contrast of the display, so that while dark areas brighten up and feature more detail, bright areas don’t suffer from overexposure. This isn’t simple all-screen gamma adjustment. Both Light Tuner and Black eQualizer address specific areas of the screen, while leaving other sections untouched.

We hope this helps explain Light Tuner and Black eQualizer, two of the technologies you’ll find on BenQ gaming monitors. There’s more, for example Color Vibrance to highlight moving objects and characters against solid backgrounds, but we can get into that in a later article!
