AMD & NVIDIA 4K Gaming with the ASUS PQ321Q Closer Look:
Setting up the display configuration is not quite as simple as you would imagine. Instead of hooking up a single DL-DVI cable and calling it done, there is a little bit more that has to be done based on the fact that this is a tiled monitor that is seen by the GPU and software as pair of panels instead of a single panel. In essence this is what you have. The initial and current crop of 4K tiled monitors use two 1920 x 2160 panels stitched together to form the display surface because there are no scalers available that support 4K resolution. To get a single, large surface you have to use the multi monitor configurations available with each manufacturers products. For AMD it is Eyefinity and with NVIDIA you use Surround. Using this UHD monitor will require that you connect a pair of HDMI 1.4 connections or a single DisplayPort connection with the panel in MST mode to take advantage of the Multi Stream Transport hub built into the PQ321Q. One thing that needs to be set up regardless of the type of GPU is the the screen refresh rate. The default rate is 30Hz; you will need to manually change this in the advanced display properties panel to enable it for use in game.
Setting up the display for use with an NVIDIA GPU is fairly simple. Install the supporting driver (currently 327.23) and away you go to enjoy some Ultra High Definition gaming. Unless, of course, you are using a pair of GTX GPUs in an SLI configuration. In that case you will need to enable SLI technology in the NVIDIA control panel. Setting up the display for use with an AMD GPU is a bit more involved, since you have to manually go into the Catalyst Control Center and set up an Eyefinity 2x1 panel. After installing the latest driver from AMD, of course. Currently this is the 13.10 Beta that supports frame metering. Then once done you can move on to enjoy some 4K goodness, again if using a pair of HD 79XX GPUs in a CrossfireX configuration you will need to enable the technology in the CCC panel.
