Only yesterday, it was reported that some M1 iPad Pro users were noticing a ‘blooming’ effect that was caused thanks to the number of local dimming zones present as a result of using mini-LED technology. Even though Apple has attempted to minimize this effect, a lot of owners were still reporting about it. Now, a display analyst talks about how it is necessary to increase the local dimming zones to decrease or outright eliminate this effect.

According to DSCC analyst Ross Young, even with the M1 iPad Pro featuring a million-to-one contrast ratio, there are chances to seeing this blooming effect. In his tweet, he outlines the differences that traditional LCD and mini-LED panels can have. Using an IPS LCD, which normally has a low contrast ratio, Young says that the halo effect can be reduced by increasing the LCD’s native contrast ratio and the number of local dimming zones.
