Query: each port works independently but not at the same time

I have connected this splitter to my HP PC with VGA, DVI and HDMI output port to my 25" monitor and to Samsun HD TV. Both ports on the splitter seem to work independently but not at the same time. If I plug in cables to both ports on the splitter at the same time neither my PC monitor nor my Samsung HD TV works. Do not buy this; donate the money to charity instead. Any amount of time and money wasted is my time and my money wasted.
