Why each option

Plasma displays achieve the highest effective refresh rates through sub-field driving technology, which can reach up to 600Hz.

APlasmaCorrect

Plasma panels use a sub-field addressing technique in which each frame is divided into multiple sub-fields that are illuminated in rapid succession, producing effective refresh rates marketed at up to 600Hz. This surpasses the typical 60-240Hz native rates of LCD and LED panels.

BLED

LED displays are a backlight variant of LCD technology and are typically limited to 60-240Hz refresh rates in consumer configurations.

CCRT

While CRT monitors can run at high refresh rates (up to ~160Hz), this is lower than the effective sub-field refresh rates marketed for plasma displays.

DLCD

Standard LCD panels refresh at 60-144Hz, which is lower than the effective refresh rate achieved by plasma sub-field technology.
