Simple, yet legitimate questions about projectors are often the ones that are assumed. A subscriber of mine once asked me what sorts of connectors should be on a projector.
First, the projector should be DATA and VIDEO compatible. This is the de-facto standard in today's projectors, but it never hurts to ask. The physical types of connectors that are common are:
DVI input– (specialized connector) – A computer-type input that uses a digital signal instead of the analog for a cleaner image. Not a common interface – yet.
COMPUTER IN (HD 15-pin) {1-2 inputs}. Also called a ‘VGA' input, this standard analog input accepts computer signals.
VIDEO input
- Composite - (Either BNC or RCA connectors) - with BNC being the better choice because it ‘locks' the cable in compared to RCA, which simply plug in and pull out.
- S-Video (a.k.a. S-VHS) – a multipin input that separates the picture and sync information from the color information. Better quality than composite.
- Component – (Typically BNC or sometimes RCA connectors) – again, with BNC being the better choice. Several ‘flavors' of component – RGsB, RGBS, RGBHV, YUV, Y Pb Pr. These are the most common types and offer the best quality picture. Component means to divide up the information into separate useable signals that are recombined at the projector for maximum quality.
AUDIO input (usually mini-phono jack) - this is not necessary if you will run audio through a mixer.
