4K TV vs. QLED TV
What's the Difference?
4K TV and QLED TV are both advanced television technologies that offer stunning picture quality. 4K TV, also known as Ultra HD, provides a resolution of 3840 x 2160 pixels, delivering incredibly sharp and detailed images. QLED TV, on the other hand, uses Quantum Dot technology to enhance color accuracy and brightness, resulting in vibrant and lifelike colors. While both technologies offer impressive visuals, QLED TVs typically have better color reproduction and brightness levels compared to 4K TVs. Ultimately, the choice between the two comes down to personal preference and budget.

Further Detail
Resolution
4K TVs have a resolution of 3840 x 2160 pixels, which is four times the resolution of Full HD TVs. This means that 4K TVs can display more detailed and sharper images compared to QLED TVs. On the other hand, QLED TVs have a resolution of 2560 x 1440 pixels, which is lower than 4K TVs. This results in slightly less detailed images on QLED TVs compared to 4K TVs.
Color Accuracy
QLED TVs are known for their excellent color accuracy and vibrant colors. This is due to the Quantum Dot technology used in QLED TVs, which allows for a wider color gamut and better color reproduction. On the other hand, 4K TVs also have good color accuracy, but they may not be as vibrant as QLED TVs. This is because QLED TVs have a higher peak brightness, which enhances the colors on the screen.
Black Levels
QLED TVs have improved black levels compared to traditional LED TVs, but they may not be as good as OLED TVs. This is because QLED TVs use an LCD panel with a backlight, which can lead to some light bleeding and less accurate black levels. On the other hand, 4K TVs also use an LCD panel with a backlight, so they may have similar black levels to QLED TVs. However, some high-end 4K TVs come with local dimming technology, which can improve black levels.
Viewing Angles
QLED TVs have better viewing angles compared to traditional LED TVs, thanks to the improved panel technology used in QLED TVs. This means that you can enjoy a clear picture from almost any angle when watching a QLED TV. On the other hand, 4K TVs may have limited viewing angles, especially if they do not have an IPS panel. This can result in color distortion and reduced picture quality when viewing the TV from the side.
Price
4K TVs are generally more affordable than QLED TVs, making them a popular choice for consumers on a budget. This is because QLED TVs use Quantum Dot technology, which can be more expensive to produce compared to traditional LCD panels used in 4K TVs. On the other hand, the price difference between 4K TVs and QLED TVs has been decreasing in recent years, making QLED TVs more accessible to a wider range of consumers.
