FAQs
What is QD-Mini LED technology?
QD-Mini LED technology combines Quantum Dot (QLED) with Mini LED backlight technology. This allows for precise control over individual LED zones, resulting in higher contrast ratios, deeper blacks, brighter highlights, and a wider color gamut than traditional LED TVs.
How does the Precise Dimming Series improve picture quality?
The Precise Dimming Series uses advanced Mini LED technology with full-domain halo control. This system precisely manages the backlight, reducing light bleed and halo effects around bright objects on dark backgrounds, leading to cleaner images and better contrast.
What is the benefit of Micro-OD technology?
Micro-OD technology reduces the distance between the backlight and the TV panel. This not only allows for a slimmer TV design but also improves light control accuracy, reducing blooming and enhancing the clarity of details in dark scenes like star fields or night skies.
Does this TV support HDR content?
Yes, the TCL 75A400U-UK supports HDR content, leveraging its advanced backlight control and wide color gamut to deliver a more dynamic and lifelike viewing experience with enhanced contrast and color.
How do I clean the screen of my TV?
Gently wipe the screen with a soft, dry microfiber cloth. For tougher marks, use a slightly damp cloth with water only, avoiding any harsh chemicals or abrasive cleaners. Always unplug the TV before cleaning.
What is the native contrast ratio?
The TCL 75A400U-UK achieves up to a 7000:1 native contrast ratio, which is a measure of the difference between the brightest and darkest parts of an image that the TV can produce simultaneously.
Can I use this TV for gaming?
Yes, the TV features advanced transient response technology to minimize motion blur and ghosting, making it suitable for gaming. Its high contrast and accurate color reproduction also enhance the gaming visual experience.
