HDMI Switch with 4K

[rld-tv01]

I have an 4K (3840 x 2160) ACER computer monitor with 1-HDMI, 1-DVI, and 1 Displayport input. I was wondering how well a cheap HDMI switch with 4K capability would work. Currently I have the computer hooked up to the display port which does 4K and my cable TV box (not 4K) to the HDMI port. I might later add other 4K HDMI input sources such as 4K DVD video type player etc.
