You set up dual monitors and restarted your pc with the cable plugged in and the tv on?

i did that and nothing

with the software ATI give you are supposed to just plug the TV in and away you go but its nowhere that simple

You are connecting DVI to vga i take it?

dvi to hdmi on the TV and dvi to vga on my monitor

if i connect the TV through vga (into the tv's pc input) it works fine but it is suppose to do HD for blu-ray and HD-DVD and gaming

dvi to hdmi on the TV and dvi to vga on my monitor

 

Try turning it all off, and just plugging in DVI to HDMI lead and not to your monitor, it may sound crazy but some times ati cards work wierd

As silly as it sounds have you clicked the detect tv button yet? It does make a difference sometimes

Read this, http://www.rage3d.com/Board/showthread.php?t=33930015 may help,especialy further down,also have you latest Catalyst drivers/software.You may also get a better result going Composit(S-Video pinout)to HDTV.

And i take it you are doing it like this, http://www.amd-firefly.com/firefly2007/fireflyclient.jsp

I know its a different card but same applies.

I'm running a 45 inch hdtv through dvi using the catalyst suite without any issues. It picks it up as a monitor straight away. If it's not even picking up a name and a second monitor it might be a input select on the tv isn't switched on.

 

I have a vga and a cvi input but you can only use one at once so might be worth checking plus as Tony says it might be worth upgrading to the latest drivers to solve any issues

i think the hdmi (of my 360) may be faulty i have got it to detect the HDTV now but no display. The tv says no signal but the pc knows its there now but if i move the cable a bit the screens flicker and cause my pc to go crazy. i have a fault on my 360 where the display goes off for know reason i thought it was my xbox but maybe not.

 

thanks for all the info guys:duffer::duffer:

try a diff hdmi cable or just use a DVID to cable if youv'e got an amp and dont need sound going to the tv

i have it working from dvi to vga but nothing with the HDMI (i dont have another to try) the tv when i unplug it (HDMI) says checking for cable so i plug it in then it says no signal so i will get a new lead the weekend

Im not really up on AMD cards, does the pc see the tv in your display settings, you might just have to click the "Extend the desktop on to this display" tab

sometimes it does sometimes it doesn't i have tried that but nothing the only time i get any display is when both are connected and the pc boots up but the screen has red all over it like its not tuned in right (fuzzy) but as soon as windows comes on the screen goes blank

ok all sorted now. i bought a dvi to hdmi lead and it works brill the blu-ray looks brilliant. the problem was the dvi to hdmi convertor that came with my new card was faulty

I use VGA straight to the HDTV from the Xbox360 and it's still capable of full HD. HDMI is just digitally connected and suffers less from analogue noise. There's not a lot in it between my HDMI-connected HDV camcorder and the VGA-connected Xbox360 though.
