How to Bring 4K UHD to Your Desktop

This is the most under-investigated and discussed aspect to 4K UHD. But we've got the answers to ensure your satisfaction. There are four key components that may need to be purchased to ensure a successful transformation into 4K UHD: A high quality 4K UHD monitor, such as the model line-up from Dell. For advanced business usage, such as video editing, make sure the monitor can display 3840x2160 at 60Hz refresh rate via a DisplayPort 1.2 interface. A high performance graphics card utilizing an AMD GPU and offering an HDMI and/or DisplayPort 1.2 interface , such as VisionTek's HD7000 series and R9 270-290 series cards. Because 4K UHD uses more memory to support its high resolution, a minimum of 2GB video memory on the graphics card is recommended. The proper cable connection for the desired use as well as the type of connection offered by the monitor and video card. For instance, while a cable with the DisplayPort 1.2 interface supports 4K UHD resolution at 60Hz, it can only do so at lengths up to 2 meters (6.5'). Alternatively, an HDMI 1.4 cable supports 4K UHD at only 30Hz, but can be run up to twenty five feet, making it the ideal connection for home theatre setups and digital signage. If you have a Mac or PC with the DisplayPort or mini DisplayPort interface and want to output movies or images via 4K UHD to a monitor that only features HDMI interface, VisionTek offers 4K UHD active adapters to help you make the right connection. Do not overlook the importance of needing a new graphics card in order to view your new 4K UHD to its fullest capabilities. By trying to use your existing card, it's akin to trying to view a DVD quality movie using component connections instead of HDMI. Saving a few dollars doesn't soothe the sting of realization that you could have watched the movie with far more visual... Read more

4K UHD allows you to get up to four times higher resolution compared to typical desktop monitors. The 4K UHD standard for consumer devices offers up to an astounding 3,840x2,160 resolution. Also known as 2160p, if you were to add up the pixels individually, the total would be a staggering 8,924,400. What used to be considered visually stunning, 1080p, can only muster up 2,073,600 pixels. And even leading-edge computers with technology that tries to emulate the human eye offers over three million less pixels than 4K... Read more
