4K Ultra HD Gaming

FullHD 1920x1080 has become the industry standard within the display industry, but enthusiasts will never settle for just standard and are always looking for the next big innovation in technology. Ultra HD gaming is the next evolution in immersion that gamers have been waiting for.
Commonly addressed as Ultra HD, UHD or 4K, this new resolution refers to the ultra-high resolutions with approximately 4000 horizontal pixels. Ultra HD resolution also has four times the number of pixels of a typical 1920x1080 resolution.

With four times the pixels, an unprecedented level of immersion can be created for gamers on a single display. Gamers will be able to experience richer details and a new sense of realism with the next generation of gaming on Ultra HD displays.

Your AMD Radeon™ R9 290X features support for Ultra HD resolutions over both HDMI 1.4b (low refresh) and DisplayPort 1.2. We recommend you do all performance testing at Ultra HD resolution to truly test what the product is capable of.

Many UltraHD/4K monitors can achieve a 60 Hz refresh rate using a tiled display configuration. AMD Eyefinity technology can be leverage to support these tiled displays by making two 2Kx2K tiles act as one 4Kx2K monitor. AMD has taken steps to make this easy for end users by providing an Automatic AMD Eyefinity Configuration features. This feature allows an automatic “plug and play” configuration of supported UltraHD/4K tiled displays when a Display Port cable is connected.

When a user hotplugs a tiled 4K monitor (such as the Sharp PN-K321 or Asus PQ321Q), a 2x1 display group will be automatically created and the two tiles will be combined to act as one monitor. This configuration will be remembered and re-enabled when the display is unplugged or the system is rebooted. It is also possible to manually disable the display group in CCC, and have the two tiles act as independent monitors. It should be noted that once the display group is manually disabled, it can no longer be automatically configured as a tiled display via the Automatic AMD Eyefinity Configuration feature.

Additionally, AMD is supporting a new industry standard for tiled displays in VESA DisplayID v1.3. The “Tiled Display Topology Data Block” describes additional display capabilities that can be leveraged to enable the plug and play experience with tiled displays. Tiled displays supporting this data block can be supported by the Automatic AMD Eyefinity Configuration with no driver update required.
