Only one USB port? [ANKAKA REPLIED] Yes. If you need some kind of input device, preferably both a mouse and a keyboard or a keyboard that has a touchpad built-in, you need either attach a hub, a keyboard with a wireless keyboard/mouse set or a pass-through set that uses a single dongle port.
What if my TV/monitor does not have an HDMI port? [ANKAKA REPLIED]You just need to buy an HDMI-to-DVI adapter. But make sure you set your screen's input settings to accept YPbPr color instead of RGB or you may get weird colors.
