The TCL A400M 55" QD-Mini LED TV has a bright, detailed picture that holds up even in busy, well-lit rooms. QD-Mini LED technology precisely controls light across the screen, giving you deeper blacks and brighter highlights with less glow around objects. Combined with Quantum Dot colour, you get richer, more natural shades. The TSR AiPQ Processor analyses what you're watching in real time, adjusting the colour, contrast and clarity for a more balanced picture.
