HD-15 (High-Density 15) is the designation for the connector commonly known as a "VGA plug". It is 3 rows of 5 pins in the same form factor as a DB-9.

DB-15 is D-subminiature 15, which is the physical connector on your TV that is labeled HDTV control.

RGBHV means Red, Green, Blue, Horizontal Sync and Vertical Sync all come in on separate pins.

This is what you would use for a PC input and you could use the same cable as was used for old Sun workstations. (HD-15 to 5 BNC)

Just like these.

Since you only have one input you would need a switchbox if you really wanted to do this.

The answer that you got at techlore is correct.

Regarding getting this running with a switchbox, This might possibly be accomplished although it will look like "Medusa's new hairdo" when you get done.

As far as I know, I have never seen an A-B switchbox for 5 BNC connectors. That would be a total of 15 BNC Connectors.

In theory (strictly theoretical and only if I had time and money to burn, I could envision this working with a VGA (HD-15F) A-B switch box and 2 HD-15M to BNC cables. and 1 HD-15M to HD-15M cable

Connect the HD-15M to HD-15M cable between the laptop and port A of the switchbox.
Connect the BNC cables to the DVR and the HD-15M to port B of the switchbox.
Connect the 2nd BNC cable between the common port of the switchbox and the TV.

Ugh. Sounds gross just thinking about it.

BTW, before you even consider a switchbox, you should first get an HD-15M to 5 BNC cable and Make sure your PC works with the TV first.

Can you give me an idea of how much this will cost and a switchbox looks like? And also why I would need BNC cables and not just a video card with s-video capability.Thanks before hand

Becasue, as I said before, "S-video will give you crappy, low-res output. "

I thought that the whole point of this was to utilize the hi-res capabilities of the TV.

If just getting any crappy signal from your PC into the TV is the goal, by all means go S-Video.

I believe that the maximum resolution signal you can put through S-video is 640 x 480 (maybe only 320 x 240)

In order to get any higher resolution than that you will need to use the HDTV input.

My off-hand estimate for parts:

HD-15 to VGA cable $15-20 USD each
VGA Switchbox $10-30 USD (Just saw one on Amazon with HD-15 to HD-15 cable for $16.99)
HD-15M to HD-15M $5-15 USD

It's probably worth getting an HD-15 to BNC cable to see what kind of resolution you will get before deciding on whether to finish the project.

You can probably find one cheap on eBay.

I'm sorry about asking so many questions but I am a "TECH-not" and I'm kinda of confused. The HD input on the back panel of the TV (there's only one) is being utilized by the HD cable box.

Yes, I know. That is why you need a switchbox is you want to use the HDTV input for both PC and cable box.

Yes. Cable hookup as normal.

60Hz should work on the PC side.

Don't worry about it. It was your help along with "Dailun" that got me this far and gave me a better understanding of what I was trying to do. I appreciate your knowledge and input as well as his. Thank you both.
