Let's back-up a bit. HDMI uses a digital output. You can't just split the cable like you would an analog signal. In other words, there is no way to halve a 1 or a 0.
So anything HDMI is powered. It can be powered by a wall wart or it can be powered by the source equipment. In the case of the powered by source equipment, this doesn't always work out well since the source equipment sometimes doesn't supply sufficient power on the cable.
Unforunately the rest of your question doesn't make much sense. "I want to watch TV on one display" - that requires one HDMI cable and "Game on the other display" - requires a second HDMI cable. Since you have two displays and two sources (one for each display), that would not require a switch.
Perhaps a diagram of what you are trying to accomplish would help me understand what you are trying to say? Also don't forget that most cable / satellite boxes also have component video outputs that can also be used to send HD to a monitor without needing a switch or splitter.
