It's impossible to help you because you have not supplied adequate information. Please complete your profile so we know which iMac you have and the version of OS X you are using. Without the basics we cannot supply any useful information.

We also need to know which iMac you have because we have no idea what output ports it has. That information is critical, iMacs have been out for years and the hardware changes so without that information we're only guessing. If you don't know which iMac you have the please click (in the upper right of this page) Support - Tech Specs and then input your serial number.

I understand you needed my iMac details and I am sorry I did not complete my profile fully when I signed in but this is the first time I have used the community help and I would appreciate yours.
I have attached the HDMI3 lead to the Imac and TV and I do have the screen saver on the TV so I know it is connected. What I am not sure about is how to watch a video on u-tube via the tv screen instead of the iMac?
I would so appreciate your help.

Move the browser window entirely within the screen you want the video to appear. Then use the controller on the far right of the youtube video to make it fullscreen on the screen the window is on. The controller icon you click is pointed by the red arrow in this image:
Lastly, when you are done watching the video, click the ESC key on the upper right corner of the keyboard.

To move the browser window to the TV, usually all you have to do is drag its titlebar to the right side, and it will move that way. Then once it is mostly there, click on the green circle in the upper left corner of the window.
If it isn't dragging to the TV screen, make sure the arrangement in Apple menu -> System Preferences -> Displays appears thus:
You do not want to mirror. And the white bar is on the screen that has the menubar and the Dock. Don't touch the white bar, unless you want to move it to a different display. Just drag the blue in the arrangement above.
That way if you drag the window to the right it will appear on the display without the menubar.
