Facts about the Image Resolution for 4K and Ultra HD TVs
Over the years there have been different labels attached to new and improved TVs. First they were labeled LCD flat screen, then HD, after that came 3D and smart TVs and now we have 4K and Ultra. It can be confusing trying to understand the differences found in newer models of televisions when compared to older versions.
Clearer Images with 4K and Ultra
The biggest difference between previous television models and the new 4K and Ultra models is the resolution. Older TVs have displays ranging from 720p to 1080p. This refers to how many dots per inch the screen is displaying. The higher the number, the clearer the displayed image. Previously, 1080p was the highest resolution available for a TV.
The 4K and Ultra models take the dots per inch and significantly increase them. In some sets, the number of pixels expands to almost 4000 for an on-screen image, creating the sharpest image available for home viewing. This increase allows viewers to see even the smallest detail in any image. It also enhances the depth, creating more lifelike images.
The Difference Between 4K and Ultra HD
The resolution displayed is the only real difference between these two models. The 4K has the highest dots per inch count, which is closer to the 4000 used in theaters. The Ultra HD has a slightly lower count, which is still significantly higher than the standard HD TVs.
The 4K models will be able to support streaming media from sites such as Netflix in a 4K format with the higher number of pixels. The Ultra HD would not be able to upscale to the higher display. People who want true cinematic quality for the movies they watch would be better off choosing a 4K TV.
Additional Choices for 4K and Ultra HD
Many manufacturers offer these newer models in a range of sizes. Because the sets are designed to replicate cinematic viewing, they do not come in sizes smaller than 40 inches. The most popular size is the 55 inch, which is available with a flat or curved screen. The curved design appears to provide a larger viewing area, slightly enhancing the depth.
Most of the new models are designed as smart TVs with built-in Wi-Fi. This means they come with apps installed for easy access to online streaming services such as Netflix. They also come with several HDMI ports for connecting external devices.
