INPUT 2 offers 5 BNC connectors, and you can select the full set of them for analog computer or video signals, or just use the traditional three for component video. You'll also note a 2nd audio input is there for INPUT 2
INPUT 3 lets you select from three different types of video signals. Use the yellow RCA jack on the left for standard composite video, use the same yellow, plus blue and red for an additional component video input. Lastly, on the right is an S-Video input, and of course a third audio input, in this case two RCA jacks for left/right, and the right jack will automatically take a mono signal and put it through both speakers, if there is nothing in the left audio jack.
As to indicator lights, from left to right; Lamp Replace, Temperature Warning, Standby/Ready, and Lamp indicator.
That takes care of the basic functionality of the hardware, it's time to consider image quality
