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?
 
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!
 
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?
 
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:

 
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
 
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?
 
Just found that adaptor and it's working now on the TV which is great news.

Just trying to work out what the difference is in terms of have I recieved a better or worse card than I should have?

The Direct CU card you have should have better cooling. I'd keep it.

Funny you should say that. We are having some serious issues that the PC crashes about 1minute into 3D Mark 2011, it doesn't do it with Prime95 though. It crashed after about 10minutes of Youtube earlier. After we plugged the TV in the computer became really unstable with just web browsing. It crashed on us 3 times just trying to make these posts. Taken the TV off it and it's fine now for web browsing.

So I actually think the card may be overheating?

When ATI/AMD design the card they produce a reference design printed circuit board - a sort of standard design.

When the card is initially released manufacturers use this reference design so all cards are the same they just have a different sticker on.

Over time some manufacturers produce their own non-reference circuit boards which may be cheaper to produce, better for overclocking, better cooled etc.

Thanks, makes sense now.

That's not good is it?
 
Got 2 fans (1 front of the case and 1 at the back), it is in the corner of the room under a desk though. 80 degrees is just totally idle.

So you recon it's just poor cooling and not actually a fault with the card?
 
I opened VLC on the TV, Media Player Classic on the monitor and then iTunes and Firefox. GPU load got up to 22% but most of the time it was sub 10%.

Temps hit 105 degrees and shut down, turned it back on straight away and just opened Firefox and it did it again.

Left it 5 mins and powered back on and temps are 85 with side of case off.

Card is too hot to even touch.
 
The card, metal heatsink and 'pipes' are boiling. The plastic bit that protects the fan and heatsink is pretty cool. The air around the GPU isn't very hot at all.

92 degrees with the side of the case off and just firefox open at the moment.
 
Yup, just stuck my finger in it and can confirm it's on!

Left the PC idle for 10 with the side off and it's down to 41.
