What is ‘blooming’ in Mini-LED displays?
Blooming, also known as haloing, is a visual artifact where light from bright objects ‘bleeds’ into surrounding dark areas, appearing as a hazy glow. It occurs in Mini-LED (and other Full Array Local Dimming LCDs) because the backlight is controlled in zones, not per-pixel like OLED. High-end Mini-LEDs like the Neo G7 minimize this effect through precise zone control, but it’s rarely completely eliminated, especially in challenging scenes with stark contrast.
Why do gamers prefer OLED for ‘clean image’ over Mini-LED brightness?
As highlighted in numerous user experiences and our Fandom Pulse analysis, OLED’s pixel-perfect black levels and near-instantaneous response times virtually eliminate ghosting and provide an incredibly ‘clean’ image, especially in fast-paced games. While Mini-LED offers higher peak brightness for HDR highlights, some gamers find minor blooming or the potential for ghosting in fast motion to be more distracting than the brightness advantage, preferring OLED’s uncompromised motion clarity.
Are Smart TV features necessary if I’m using it as a gaming monitor?
Not strictly necessary. If your PC or console handles most of your media and streaming, the integrated Smart TV platform might be redundant. However, platforms like LG’s webOS offer convenience for quick streaming access, apps, and smart home control without needing to power on your gaming device. For a dedicated, single-purpose monitor setup, these features are often a secondary consideration.
