I have an IBM ThinkPad T22. for the life of me i can not figure out why my s-video doesn't display on my TV. I can hook a desktop computer monitor up to the monitor port on it and it works fine. The minute i hook the s-video up nothing displays on the tv. The laptop runs fine doesnt lock up or anything but it won't display on the tv. Is there a driver or program I need to run it? also I have an ifra red port on my T22 do I need a program to run it?

Short expert note for (and following ): the T22 does include a TV‑out and an infrared (IrDA) port — the display output has to be switched to the external connector, and ThinkPads provide a keyboard toggle to do that. (manualzilla.com)

Practical S‑video troubleshooting (most common fixes):

  • Make sure the TV is set to the S‑Video input and the S‑Video plug is fully seated; try a known‑good S‑Video cable or another TV to isolate the cable vs. laptop.
  • Use a proper S‑Video lead (mini‑DIN). S‑Video is a standard‑definition signal that carries luminance/chrominance separately; simple RCA/composite adapters often behave unpredictably. (en.wikipedia.org)
  • After plugging in, press the ThinkPad display hotkey to cycle outputs (LCD ↔ external). If an external VGA monitor is attached, disconnect it for the test — some ThinkPads/driver combinations limit VGA and S‑video output combinations. (thinkwiki.org)
  • If still blank, open your OS display settings (display/driver control panel) and choose a TV/standard‑definition mode or “mirror/duplicate” so the laptop sends a TV‑compatible signal; update or reinstall the video driver from the vendor if needed. ()

Infrared notes:

  • The T20/T21/T22 family lists IrDA 1.1 hardware — using it requires the OS IrDA/infrared support or vendor driver and the port enabled in system setup if applicable. For file transfers use the OS infrared settings or the Infrared/“Wireless Link” applet. (manualzilla.com)

If these checks fail: swap cables/TVs to rule out a bad lead, remove any docked monitor, and try the S‑Video with another source (DVD/VCR). If VGA works but S‑video never does after all the above, the S‑video hardware or its connector wiring may be faulty.

I don't think your video problem is driver-related -- there are only a limited number of resolutions which are supported by the S-video output. Try 640 x 480 first, then 800 x 600, both at 60 Hz vertical refresh. I can virtually guarantee that 1024x768, for example, ain't gonna work.

If you are using the s-output regularly, you may find the free utility MultiRes useful -- it allws a user to switch resolution and vertical refresh on-the-fly.

As far as the infrared, a Google search is fruitful.
