Hi, I recently brought the ATI Radeon 2400 HD card with HDMI output. I have my PC monitor connected via VGA and my Panasonic Plasma via HDMI however I have no picture or sound via HDMI and the video card software does not detect or give me any options for HDMI or a 2nd monitor. Any suggestions would be much appreciated. I have downloaded the latest drivers ( I believe? )
Thanks

Are you running the 2400 as a dual screen card (ie using both DVI outputs) or trying to use your onboard VGA + 1 of the DVI outputs on the 2400 for HDMI?

Hi, thanks for helping. I am trying to use both the VGA & HDMI on the 2400. I hope this is possible?

Yes this is possible.

What model TV do you have?

Is there any reason why you aren't just using the VGA input on the TV? This will typically be a lot easier to configure and IMHO the only reason you really need to go down the HDMI track is if you want combined audio+video over a single cable or need HDCP support to playback Blu Ray or HD-DVD. Most older TV's cannot do 1:1 pixel mapping, this means that each pixel the PC outputs doesn't align directly with the TV's pixels which results in blurry text.

As far as I am aware this card has 3 outputs, 2 x DVI and I x HDMI.

In the default configuration, it is the 2 DVI outputs that are active. You can check this by connecting the TV to your second DVI o/p.

Somewhere in the ATI software should be the switch to activate the HDMI o/p abd de-activating the DHCP DVI o/p. Unfortunately I am now running Nvidia cards so can't help further, if I've even helped at all.

Cheers

Ive looked everywhere in the software and for some strange reason there is no mention of HDMI?

From memory it shows up as a 2nd DVI port. The video card doesn't know you're using HDMI - it just sees it as a DVI port.

When I try to enable the 2nd monitor/TV by right clicking the 2nd monitor icon it tries to but doesnt and the icon stays grey instead of black and the only option it gives me is "enable" again? Shouldnt HDMI be just plug and play? There is no 2nd DVI option either. It seems something is happening down the HDMI cable at least because when I turn the TV on & off my primary monitor does a little flicker. Cheers again

Happy Xmas,

Just a thought. Make sure your current resolution is less than or equal to the resolution of the TV.

How were you hooking up the HDMI cable originally? Did your card come with a DVI->HDMI adapter or did you purchase one seperately? There is no difference in picture quality between DVI->HDMI or HDMI->HDMI, you just get added audio.

Hi, I brought the card because it has its own HDMI output aswell as VGA and DVI so I simply want to do straight HDMI to HDMI, thanks

An american with the same problem:

That is an ATI2xxx forum with some fairly knowledgeable people. Hopefully you will get the answer there in due course.
