4K Monitors at Overclockers UK

Overclockers UK specialises in the latest display technologies and stock a range of 4K monitors, also known as ultra HD monitors. 4K monitors deliver extremely sharp images with individual pixels not visible to the naked eye. This level of ultra-high clarity is invaluable for gamers, as well as photo and video editors. Be sure to check out the full range of 4K products available at Overclockers UK today.

How is a 4K Display Different?

Much like original HD and full HD, 4K is a resolution that’s measured in pixels. As a reference point, 4K features about four times the resolution of full HD, which is where it gets its name. Below is a breakdown of the different resolutions:

  • Original HD: 1280 x 780
  • Full HD: 1920 x 1080
  • 4K HD: 3840 x 2160

4K PC monitors represent a huge leap forwards for display technologies by increasing picture sharpness and clarity, while also allowing for larger displays at higher resolutions than ever before.

4K Monitors and Pixel Density

Understanding pixel density is important when choosing a 4K computer monitor. Pixel density is what makes a digital image more realistic. This technology originated in smartphones and tablets, but has since spread to monitors and TVs. As a general rule, the higher the pixel density, the better the display.

The distance at which you view a device also plays an important part in this. For example, smartphones are generally used close to the eye, which means that a high pixel density is required otherwise the eye will detect them. As a result, the average smartphone has a pixel density of 300 pixels per inch (or ppi). Laptops are used at a distance, so the pixel density doesn’t need to be as high, a 120ppi will normally be enough. In contrast to this, traditional Full HD monitors typically only feature around 40ppi.

4K screens take this one step further. Pixel density in 4K monitors can vary, however, they normally feature around 150ppi, meaning that with a 4K screen it is impossible to see the pixels, even at close range.

How to Choose a 4K Monitor

System Requirements

With a pixel count of 8.3 million, 4K resolution monitors require much more power than the average computer. It is possible to run a 4K monitor with an AMD Trinity or Intel Ivy Bridge processor, however, these often lack the power and connectivity required. The best solution for running a 4K monitor is a dedicated graphics card. AMD and NVIDIA are the leading manufacturers of graphics cards capable of handling 4K display.

Connection Ports

HDMI 2.0 port is a newer type of connection found on the most recent 4K monitor models and will become the standard in the future. That said, most 4K monitors feature a HDMI 1.4, 1.2 or both. There are several differences, but the most important one is that HDMI 1.4 is only capable of outputting 4K at 30Hz, which is slower than the maximum and will affect the overall experience, particularly in gameplay. However, 1.4 is capable of outputting 4K at 60Hz. So, before you buy a 4K monitor, it’s important to consider which connection ports are available.
