Can I use DVI to S Video Adapter to Connect HP Monitor to Direct TV Receiver? - PeachParts Mercedes-Benz Forum

I have an HP w2007 monitor which is terrific, but woefully underused, and I want to use it as a secondary TV in my home office.

Direct TV (non-HD) DVR receivers have S-Video outputs and the HP has a DVI input. Will an S-Video to DVI adapter solve that problem -- and will there be a loss in image quality?

I have never seen a simple S-video to DVI adapter cable since the only analog signal on DVI are the component signals.

There may be a simple adapter that has a few active electronics to do the conversion but I'm thinking that you'll need a device called a scaler to convert the signal. These can range from about $150 to several thousand dollars.

There will be a difference in picture quality that's usually a factor of the quality of the piece of scaling equipment.

It would work with a device like this:

Without something like that, not going to work.

I see the problem now -- trying to send an analog signal through a digital connection.

What about S-Video (from receiver or DVD player) to VGA (Monitor). Both are analog and, given the size of the screen (20") and the distance it will be from my desk (about 8-10 feet) the picture will be sharp enough for watching CNN (or Star Trek) while I work.

EDIT: Actually, i can see this will not work without a video card between or within the receiver. Since the satellite receiver is a DVR, which is essentially a PC, I figured it would work.

S-video is Y/C - luminance and chrominance. VGA is analog RGBHV. You need something to resolve the differences in the signal types even though they're all analog.

How about this:

1. Switch to HD receiver with HDMI output
2. Get HDMI to DVI cable/adapter
3. Connect cable to LCD monitor
4. Run separate audio from receiver to speakers

Would that work?

Yes, that would work.

If it was me, I'd get a cheapy S-video capture card or a TV tuner card and hook up the output of the Sat receiver to the computer then run the HP monitor as a second screen on your desktop.

You can run the video as a window or full screen on either screen or use it in dual mode when you want more computer real estate.

Read the reviews though and know what your getting.

I'll check that out.

Now my only challenge will be seeing how HD resolution will look in the monitor's 1680x1050. I assume it will be permanently letter boxed?

If it is a 22" monitor it may be able to do HD......if its 20" it will still look ok....

iwrock · #10 08-31-2009, 08:39 PM

Also - want to check if the HD box does HDCP and if the monitor does HDCP.

OK, after all the research I will be choosing option B (or is it D by now?):

Connect a DVD player with DVI output to the monitor and just watch DVD's.

Since I won't get full HD resolution with the 20" monitor it would not make good economic sense to hook it up to an HD receiver.
