What is the ProArt Cinema PQ07, you may ask? Thank you for asking. It’s a 135-inch MicroLED display. MicroLED is not to be confused with Mini LED — wherein LEDs are arranged into local dimming zones — which is very common on modern televisions. MicroLEDs, by contrast, try to beat OLED at its own game. They are microscopic in size, and each pixel is formed from a cluster of them. The result is a panel with significantly better brightness and contrast than you see from even the fanciest OLED screens today.
