Samsung’s latest innovation, Micro RGB tech, is a bit of a mixed bag. Despite its promising features, it still uses an LCD panel with a backlight, which is misleading given the “Micro” prefix. This means it doesn’t have individual LEDs like microLED displays do.
The main difference between Micro RGB and existing LCD gaming monitors is that the pixels are controlled by separate RGB LEDs in the backlight, rather than white LEDs lighting up subpixels. In theory, this should improve color fidelity, but in practice, it’s complicated. The number of dimming zones is higher, potentially allowing for more precise control.
However, Samsung hasn’t disclosed exact numbers, and the zone count is roughly three times that of mini-LED TVs with local dimming. A 4K display would need over 1,400 pixels per zone to match the backlighting, but an 8K model has around 5,500 pixels per zone.
The problem lies in finding a balance between color and detail. The more zones there are, the more compromises are needed. While Micro RGB offers vivid colors and brightness, it can’t match OLED’s perfect per-pixel lighting control. This technology may appear in PC monitors soon, but its limitations will remain.
