Thimkpad t20 s-video not working

To get your display to duplicate onto a TV through HDMI, here are the steps you should take. Right click on your desktop and click on "screen resolution" (or "properties" if you are not on Windows 7, then go over to the screen resolution tab). From there, select the second display. This should look like a grey'd out monitor with a number "2" on it. Set the Multiple Display option to "Duplicate the displays."

For one you must have the right kind of cable, what kind of cable do you have?

I would check the video setting on your laptop. The resolution or refresh rate might have been changed and the LCD TV might not be able to process the signal. Try changing the laptop's resolution to the lowest setting(right-click on desktop and pick properties) and see if the TV produces a picture. Also verify the video output on the laptop is working by hooking it up to a computer monitor if available.

You set it to Multiple Monitors (if you move the mouse, you will probably be able to see it on the TV once it "goes out" of the laptop desktop). You need to change output mode to external S-Video.

First of all try hitting Fn + F7 key to switch to Ext-S-Video. If it works, that's it, of course. If it doesn't, TV output is not enabled.

Right-click on the desktop to bring up the Properties, go to Settings. You'll see two monitor images there, 1 and 2.

Click Advanced, then go to Displays. You'll get CRT, TV and LCD. Turn on the TV button and tune your settings.

At this point, the hotkey Fn + F7 is enabled to cycle between LCD and TV.

If it still doesn't work and you see the blank desktop, go again in Display Properties, choose LCD as Primary Display, select Secondary, and verify that "Extend desktop on this display" is NOT checked.

hi there! first to check here is the HDMI connection, if there are okay then next to check is the desktop properties on PC. From desktop open the Display Properties and go to Settings Tab. On that window you to ensure that you are selecting Multiple Monitors on the display. set the resolution of your display to minimal ratio just to avoid some error such as Mode is not Supported.
Hope this could help.

Sounds like you need to make sure the proper video drivers are installed. Head on over to: http://www-307.ibm.com/pc/support/site.wss/product.do?doctypeind=9&template=/productselection/landingpages/downloadsDriversLandingPage.vm&sitestyle=lenovo

And input your systems specific information to grab the lastest video driver for it. See if that helps at all.

Hi,
This may sound silly but it is often overlooked by many people......Have you changed your T.V channel to AV? There is usualy av1 and av2 options. Try these and let me know if you have any success or not.

Hi,

Thanks for all the details..

The issue seems to be with the video card drivers here...

Go to www.hp.com/suport and download the latest video card and the chipset drivers

before you download ...uninstall the nvidia chipset or any display software from program and features.

after you have installed the software.. go to the nvidia control panel > setup multiple monitors. and browse throughout the options >
It should be dual display and not extended display.

Also try with a new user profile...

Hope this helps..

Right click on an empty portion of your desktop, and go to "Properties" at the bottom.

Here you will find the display options for your computer. You will probably see that you have the option to set a new display, or add a display for use in conjunction with your current.

What you need to do is enable your second display "2", as the S-Video, so that the signal goes through to your TV, and then all should work just fine.

You may find that you need to change your resolution settings, as your tv has different dimensions and so on, but that is very easily fixed from within your display settings.

I hope that this has helped to fix your problem, good luck!

There is an S-Video port and VGA for external display
but you can see display in any one of them not on two monitor
simultaneously
