Are there any disadvantages with using S-Video instead of a regular video cable for a DLP projector? |

S-video is the min. I would use. Component (NOT COMPOSITE) is next best. Since you mentioned Digital Light Processing (aka digital fixed resolution panel) you're best option would be DVI/HMDI. If you are using Direct TV, Digital Cable or DVDs, your source material is in a digital format. Your display is also Digital so it would be best to feed it a digital signal. Composite, S video and component video are all analog cables. In this scenario, the source component (dvd player, STB) must convert the digital signal to analog and send it to the DLP display. Since the DLP display wants to see a digital signal it must convert it back to digital. The D/A and then A/D processing degrades the signal. If you have a Dvd player or STB with an HMDI or DVI output, you can keep the signal digital the whole way. You'll get a much improved picture (one that has not been degraded and is more accurate).

You would need a DVD player with HD-Upconversion in order to get the quality of DVI/HDMI. The prices on them have dropped dramatically. There are some good quality ones out there for about $120 |
There is only one DVD player that I am aware of the upconverts via the analog output and that is the Bravo DVD player I posted a link to above. The problem is Hollywood is obscessed with piracy and has effectively scared the DVD player manufacturers into not offering analog upconverted signals. Even so, since the component signal will go through 2 additional processes D-A-D there will be some signal degredation so it won't be as good given equal source material and electronics. I would recommend wiring for S-video (for gaming), component (DVD, HD STB), DVI (future DVD purchase, HD STB) and a 15 pin (computing). Bomber |
| For longer haul composite/component/s-video runs I you may want to look at using some good RG6 (cable tv cable) with adaptors to change the F connectors to RCA (or s-video). It can be alot cheaper than custom cables and it has better shielding than standard cabling. |
Just make sure you use quality connectors though. No need in putting together a nice home theater and using $20 worth of connectors. Definately don't want to skimp on your cables considering you have to have a means of sending the signal from one component to the next. Dont' want the cabling to be your weakest link. |
