New build.... can't output to TV?

Just did a new build for someone, they have an Asus HD 6870 1GB graphics card and it's got two DVI slots.

I've connected 1 up to his 24" monitor and thats on 1920x1080 and running with no issues.

He also has a Toshiba Regza 26AV713B (VGA connection at back) which he use to connect up via a VGA cable on his old computer. New graphics card doesn't have a VGA port (motherboard does though) so we've got him an adaptor and used his normal VGA to VGA cable and popped the adaptor on so it would connect up to the second DVI slot on the graphics card but no matter what I do I cannot get it to display anything.

I then tried a proper DVI to VGA cable and same result. Tried putting resolution down on monitor to 800x600 and no luck, installed drivers for graphics card from CD and they didn't work so did scan for hardware changes and it downloaded new drivers via device manager and still nothing.

Windows control panel just shows the monitor and so does ATi control centre, neither detect the monitor.

Any ideas? The box of the graphics card even advertises some eyefinity multi-display thing but I can't find anything on the CD with a program to help.

Driving us nuts at the moment so any ideas?
 
My 6850 has 2x DVI, but only 1 of them will also output VGA for an adapter.

Of course, it's also possible that it doesn't output any VGA.


But - as said, DVI-HDMI or even HDMI-HDMI lead will be the easiest way!
 
The HDMI cable I've got is about half a metre too short where as I've got hundreds of these VGA and DVI cables so I was hoping I wouldn't have to go and get another sodding cable!
 
As confused wrote- only one of the dvi can output to VGA. Swapping cables may put the TV as monitor 1 but you can always swap it back so monitor is primary and TV is secondary.

I plugged my VGA monitor into the wrong DVI and I got nothing on the screen.

HDMI is good for carrying audio as well so might be worth grabbing a longer cable.
 
Just ordered a 5m cable from play for like £3.50, just annoyed that's all.

Does it have to carry audio? The speaker setup gives better quality than the TV audio so they want to use the PC audio.
 
HDMI cable arrived but the ports on the back of the graphics card are not standard HDMI ports?

I have one on my motherboard and the cable plugs fine into that but the 2 on the motherboard are ever so slightly different and the cable will not fit.

The inside of a HDMI port should be straight like this:

Instead these ports are like this:

With little 'book ends' on each end.

Any ideas?
 
Does it look like this:

That's two DVI ports, two mini DisplayPort and one HDMI port.

A HDMI connector looks like this:

You either have the wrong cable or you're trying to plug it into the wrong socket.

Or if it looks like this:

then that has two DVI ports and two DisplayPorts but no HDMI.

In that picture the top DVI port, next to the exhaust is dual link, so put the DVI to PC cable in there. The bottom DVI port is the single link and also analogue, so you should be able to use a DVI - VGA adapter to the TV with this port.

But now you have an HDMI cable you may as well use that instead of the VGA :)
 
I have 2x DVI and 2x HDMI, but the inside of the HDMI is different.

I use one of the DVI ports to DVI to the monitor leaving me with a DVI free (told above I cannot use this to connect to TV) and 2x HDMI ports free. I have 1x HDMI port on the motherboard as well.

I've got 3 HDMI cables here, all 3 fit into the TV, a Xbox 360 and the motherboard. None of them fit into the HDMI slots on the graphics card. See my crud paint image below:

 
Your card must be like the last image in my post above.

You have 2 DVI and 2 DisplayPort. Sorry, you don't have HDMI on that card.

Urgh, why would there not be HDMI?

Infact THIS is the card I ordered.

It says 1x HDMI and 2x mini display ports?

Have I recieved the wrong card?

You know what I better get it from under the desk and check a HDMI port wasn't hidden by the cables down there......
 
Nope, I have 2 DVI ports and 2 of these other ports.

Yet the card I ordered (checked part code on invoice and on website matches) says

Display Connectors: 2 Dual-Link DVI-I, 1 HDMI & 2x Mini-DisplayPort
 
Looks like you got a different version of the card.

Back to your original post, the bottom DVI connector provides an analogue VGA signal.

Box says Asus HD 6870 Direct CU and has a sticker for GX-240-AS on it but confirms on the back that the ports are DisplayPorts and not HDMI.

So the website is just wrong basically?
