The DVI-D input connector on your TV is digital. VGA is analog. You need a video card with a DVI-D, or HDMI, or component video output for your TV.

The connector shown (by the jpg) is an adapter not a converter. It's meant to adapt a DVI-I output (from a video card) to a monitor VGA input. Some video cards uses a DVI-I connector to carry both the digital (for DVI-D interface) and analog video signals for VGA interface. The DVD-I connector has 4 extra pins around the long blade pin (Ground) for the analog VGA video signals (Red, Green, Blue, Sync and Ground). An adapter (similar to the one you shown) plugged into the DVI-I connector of the Video card, routes these 5 analog signals to the appropriate pins on the VGA end of the adapter which is then connected to a monitor VGA input. The DVI end shown on the jpg adapter is not even a DVI-I since it's missing these 4 analog pins. Even if your adapter had the correct DVI-I end, it would still be useless for your application.

Get yourself a VGA to Component converter dongle for under $100. I have one for my laptop and although the resolution isn't the best on a big screen, it does the job. As long as you have a VGA output on the computer and Component IN on the TV.

Hi Ive got my HTCP computer setup now I need to look into the monitor. Im wondering about HDMI capability. If the monitor has HDMI can I then hook my HDMI cable to my LCD tv and play Hi-def movies off of my cpu on to my TV in true HD? What would be the purpose of getting an HDMI outlet on my monitor? My CPU also has an HDMI plug in.

OK guys (and girls)

I bought this "PC to TV" thingie (made by Kworld)
Its a totally hardware piece of equipment, it says it doesnt need any hardware, and yet it doesnt do anything at all!!

It doesnt work, no lights are flashing, it doesnt do anything FFS!!!!!!!

*getting quite angry*

Can you elaborate?

It would really help to know what you have for a video card. This whole thing might be very simple. For example if it's an ATI card, then just use the DVI cable, no converters. Open the CCC and select "clone mode". This makes the TV a duplicate of your monitor in all aspects. The other mode, "theatre" extends your desktop to the other monitor. You can drag your media player over there while the game is playing, and keep your normal desktop for surfing.

As an option, it looks like you have a Component input just to the right of the DVI. (tell video director to add more lighting!!!) Depending on the video card, you might be able to go that route too.

Did you power your Kworld "PC to TV" converter? Some of these devices get their power from a USB port (from the PC), or a Wall-Plug in power supply.

I have a ATI Radeon 9200 card, but I have no clue how to do what you wrote :confused:

Yep, did that and it still doesnt work

Here's my dilemma better explained through video:

Well that's a better vid!

Your poor old video card is somewhat lacking. It does have an S-video out on the back. You could use this straight to the tv's s-video in however I see you already have something plugged in there.
As Jlet noted, your video card only outputs either VGA or S-video. The TV will not recognize the VGA on it's Digital (DVI) port.. bummer!

You have 3 solutions.
1) buy a newer vid card that has DVI outputs or will covert to Component (RGB), which most do. (best solution)
2) buy a newer TV that has a PC (analog/vga) input. OUCH! On the bright side that nice long VGA cable won't be a waste of money anymore. (most expensive solution)
3) use the s-video. (CHEAP!!!)

I bought a new video card today, its a GEFORCE 6200 AGP
This damn thing better work or I'm gonna put my fist through the monitor

Sure enough when i get home the S-Video cord doesnt fit into the port :rolleyes:
The Video card port has the newer S-video hole with 9 holes.
The cable I bought has the old 4 pins :mad:

That nine hole port SHOULD have an adapter in the box. Typically they're multipurpose ports. If it's not there, take it back.

I'm not sure why you bought a new card if you're going to use s-video. The s-video should plug directly in the original card. If not, there should be an adapter for it too. Phone Dell and complain if it's not there and needed.

But, now you have a real DVI port, and you just need a dvi cable. Using the adapters supplied won't work with your long vga cable. :( More $$$
By the time you're done you should be an expert!

DVI cable wont work either because the outlet on my TV is DVI-D and the port on my video
card is regular DVI :eek: :(


BTW Does anybody know where I can buy 9-pin to 4-pin S-video connectors????

Never mind, I'm a F____ing idiot, I found the connector in the box....DOH!!!
(Thanx Berty)

It also comes with a DVI to VGA connector plus HD cables.
I managed to get the S-Video working now
Will try DVI HD later

Cheers!! :p

The S-video works nicely but here is a bit of video quality loss.
Not much though, its still worthwhile

I'm wondering if the DVI cable will improve video quality :confused:

On the ATI products, you can plug a standard 4-pin S-Video cable into the ATI multipurpose S-Video port. The other extra pins are usually used to also carry the composite video signal. ATI makes a custom S-Video to Composite video (RCA connector) adapter (as mentioned by Berty). In you case, you don't need this adapter since your TV has a S-Video input.

I don't know about the Geforce DVI connector, but ATI uses a DVD-I (universal) connector which can carry both the DVI-D (digital) and DVI-A (VGA analog) signals. You can plug a DVI-D cable into a DVI-I connector. That is what you need for your TV provided the Video Card Software accepts your TV DVD-D interface. My ATI 9600 DVI port software interface will NOT accept my Sony TV although it will accept more recent Sony TV models. I have to use the custom ATI DVI to Component Video adapter (dongle). Inserting the dongle into the DVI port tells the ATI software to reconfigure its default VGA analog signals to component video signals.

Note: The PQ using VGA, DVI or Component Video will be far superior than S-Video.

Thanx Jlet, I'm gonna try the DVI next

The S-video isnt half bad though

TorontoGringo

Nope, the DVI to DVI-D cable doesnt work, I'm getting black screen
Only the S-video works so far

I also have HD cables (green,yellow,blue & red), I'll try those later

I have a Mac Pro computer with 2 DVI connectors. One DVI is connected to my Apple Cinema Display Monitor. I connected my Computer to my LCD Tv with the DVI cable. I bought an HDMI to DVI connector end. Picture is a bit fuzzy. Would the picture be better if I used a DVI-VGA cable instead to connect the Mac to the LCD tv? Would a true DVI-Hdmi cable be better than what I did by buying an HDMI end. Thanks

I have another question, when I want listen to the audio from my computer onto my TV I have to disconnect the PC speakers and connect the wire from my TV audio.

Is there some kind of splitter that I can buy so I can hook up both my PC & TV audio at once???
Preferably on that has a switch so I can toggle between both????
