What Is 4K Ultra HD TV?
4K Ultra HD (UHD) is the most common display resolution found in modern televisions. A 4K TV features a resolution of 3,840 × 2,160 pixels, which equals more than 8 million individual pixels on the screen. Compared to Full HD (1080p), a 4K display contains four times as many pixels, resulting in sharper images, finer details, and a more immersive viewing experience.
What Does 4K Resolution Mean?
The term “4K” refers to the horizontal pixel count, which is close to 4,000 pixels. In consumer televisions, 4K Ultra HD has a resolution of 3,840 × 2,160 pixels. This has become the standard resolution for most mid-range and premium TVs available today.
Professional digital cinema uses a slightly different 4K resolution of 4,096 × 2,160 pixels, but the difference is minimal for most viewers.
4K vs 1080p: What’s the Difference?
A Full HD television has a resolution of 1,920 × 1,080 pixels, while a 4K TV has 3,840 × 2,160 pixels. This means a 4K display contains four times more pixels than a 1080p display.
The increased pixel density allows images to appear sharper and more detailed, especially on larger screen sizes such as 55-inch, 65-inch, 75-inch, and 85-inch televisions.

4K Gaming
Modern gaming consoles such as the PlayStation 5 and Xbox Series X are designed to take advantage of 4K displays. Many games support 4K graphics, HDR, and high refresh rates, creating a more immersive gaming experience.
When shopping for a gaming TV, look for features such as HDMI 2.1, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM).
