AMD R9 290X & R9 280X Vs Nvidia GTX Titan & GTX 780

Setting Up

The PN-K321 4K monitor from Sharp is pretty much plug and play if you use a DisplayPort connection like we did, and we of course recommend this method of connection. It goes without saying that you should use a latest generation graphics card with DisplayPort 1.2 MST compatibility, this includes most cards from the GTX 600/700 series and the AMD HD 6000/7000 & RX 2XX series. We’d recommend that you double check compatibility first but for convenience we can confirm all graphics cards in this 4K gaming round-up support DisplayPort 1.2 MST.

AMD’s CCC recognises the Sharp PN-K321 monitor as an eyefinity display formed from the two stitched panels we mentioned earlier on.

AMD’s CCC has an advanced DisplayPort diagnostics tab which lets you see how much bandwidth is available and how much bandwidth each of the two stitched displays are using.

In the Nvidia control panel it also recognises that there are two displays present and it automatically combines these to give you a single display.

Both Nvidia and AMD had absolutely no troubles setting up the 4K monitor. As long as you have a graphics card that supports 4K, has a DisplayPort 1.2 MST port and is using the latest drivers then we can’t forsee you having any issues.
