Ok, basically im trying to use my tv as a secondary display on my computer and its not working. Unfortunately my tv is rca and my radeon x1600 does not have an rca port, only svideo. so i am using an svideo to rca adapter attached to a 6 foot rca video cord to connect to my tv. My video card does seem to be recognizing the tv because when i plug it in and press the detect displays button in the displays manager of my Catalyst Control Center a tv icon appears in the "Attached displays currently disabled" box. From their i gather im supposed to right click on that tv icon and a pop up menu is supposed to appear allowing me to select the desired desktop mode. however, when i right click it i dont get that popup menu, nothing happens. Also if i try to right-click the greyed out number 2 display icon in the right-hand box and click Enable in the pop-up menu, it will try to enable, the screen will refresh and it will be greyed out again. When i was playing around with the displays manager at one point i dragged the tv icon in the "Attached displays currently disabled" box onto the monitor icon in the "Main" displays box and i got the option to switch displays. This did actually make my tv work as the main display, however it was in black and white, and it meant that my monitor was disabled instead, so it was kind of pointless...
I should note that I have tried doing this with 2 different versions of the ati video card drivers and still had the same outcome. Right now i've got the most recent version (7.12).
I'm pretty sure my radeon is supposed to be capable of using rca tv's as a secondary display, after all it came with the freakin svideo to rca adapter! so whats the problem here??

I've attached a screenshot of my displays manager, in case that might help somehow. Thanks in advance!

Hello.
I have a regular TV that I am trying to connect, but I have the same problem as you. So I dont think its a problem with the TV. I am able to swap the monitor with the TV, so I get the picture on TV, but my PC monitor goes black. I just want the picture on both.

You have to go to display properties (via control panel), on the settings tab, left-click on the second display in the picture, and check "Extend my desktop on to this monitor." Click on the Advanced button and there should be a way to tell it exactly what to put on the TV screen (e.g. mirror the desktop, span, dualview, etc.).

What kind of video card do you have and is the TV plugged directly into the computer (no devices between it and the TV)?

I also have the exact same problem. I have a CRT TV which I connect directly via S-Video to my HD 2600XT. I have tried enabling the secondary display (TV) in every way possible through both CCC and windows display settings. If anyone has any tips or ideas, they would be appreciated

I have exactly the same problem, have tried all sorts and can't get the secondary display to work properly. All the guides say what to do but it just won't work!
Did anyone work this out?

Thanks

:/ Hi All.
I have the same issue as Graydon with a Vista Ultimate PC and a ATI 2400PRO.
I get the same greyed out 2nd display, I have tried new and old drivers to no avail.
Both monitors are detected under hardware manager but one cant enable them either under
display or in the catalyst Control Centre, when I try it refreshes and then greys out.
I have a support call open with ATI but no results yet. If I plug the S-Video cable into my XP notebook it works 100%

Graydon, what OS are you running?

I really hope somebody has the answer.

info: intel 865GBF, P4, 1GB Ram

EDIT: Going to try some suggestions from http://www.driverheaven.net/windows-xp-2k-radeon-display-drive...nable.html

and http://ftp.computing.net/hardware/wwwboard/forum/45186.html

Got it working!!

My graphics card has 2 x DVI output ports plus the S-Video output.
My LCD monitor was connected to the DVI port (via a VGA to DVI adaptor) on the right side (when viewed from the back of the computer). I switched the monitor to the left side - make sure your computer is off before you switch.
On start up the new hardware wizard installed my monitor again - but then it also found new hardware - my TV!. I followed the install instructions and then went through the same things as yesterday - but this time it worked no problem. switched on the tv and theres my desktop image cloned!
crazy but brilliant

good luck

Glad it worked for you. :) View from the back I have a VGA port on the right (plugged to a LCD via VGA cable) then S-Vid then DVI. Found a DVI to VGA adapter this morning so will try that over the weekend. DVI to VGA on left and S-Vid then see what happens. Will let you know.

Plug in VGA via DVI to VGA adapter and.... Bingo, SVIDEO works. And a logged call with AMD/ATI could not get me the solution.

Now all I need to do is figure out how to get a higher refresh rate than 25HTz Interlaced.
If I plug Svid into my laptop (intel gfx) I can run at 1024/768 at 60HTz but I can only get 25HTz on the ATI card, any ideas??

Also tried a DVI to HDMI cable but could not get it to work.

This worked for me as well! Simply moved my monitor to the right output (looking from the back) and bingo, worked perfectly. What a weird solution!

Hi guys, just wanted to check before i go out and buy a convertor. My monitor is plugged in to the VGA port, and like you, i cant get the display to appear on the tv at the same time as my monitor. And, the only way i can get the display to my monitor if i have swtiched the display to my tv is to shutdown and boot up again, very odd.

So, just to confirm, if i get a VGA to DVI convertor and put that in the DVI port, in theory, i should be able to bring up the display on my monitor and tv (via the S-video cable)?

Hi

In Theory yes, plugging in a DVI to VGA adapter and using that for your monitor should solve your problem. Good Luck
