I have a 27 inch 2560x1440 Xstar (Korean) monitor, overclocked to 120hz, and it has one dual DVI-D input.

I would like to connect that monitor to my PC, Chromecast and Xbox by using a HDMI splitter like this one: http://www.amazon.co.uk/dp/B00KCPY5Y0/.

Would it be possible to run the configuration below whereby the monitor is @ 120hz and 2560x1440?

HDMI Cables

PC,Chrome Cast, Xbox HDMI CABLE to HDMI SPLITTER BOX to HDMI to DVI ADAPTOR to 27" Monitor 2560x1440 @120hz

Many thanks for your help in advance.

According to page of that HDMI Switch that you are planning to buy, the HDMI version 1.4 is supported. The maximum speed of the data transfer over HDMI is given here, as 8.16 Gb/s. Notice that the speed is measured as Gigabits per second.

Now, what you want to render is 2560x1440 at 120hz. Calculating the bandwidth required:

2560 x 1440 x 120 x 24 = 10616832000 bits/s

This is approximately 10.62 Gbit/s (1 Gb/s = 1,000,000,000 bits/s). This is more than what HDMI v1.4 is said to be capable. So, it might not be possible to render at such a high fps.
