How do I connect a laptop to this tv?


It will depend on the laptop's available external video ports. You can connect a VGA cable from some laptops to the VGA port on the TV. Then plug in a 3.5 mm audio cable from the headphone jack to the PC audio in port. (The audio connection is optional. You could continue using the laptop's speakers.)

Make the connections with the TV and the laptop off. You may need to enter the BIOS to enable the external video port. (It can be turned off to save power. The BIOS is accessed on boot by pressing a key (Esc, F1, Del) noted on the splash screen. For Win8 machines, you'll need to do a special restart.) Then turn on the TV before turning on the computer. The TV monitor should be automatically recognized for resolution and refresh rate. Next, if you have a Windows system, right click on the desktop (pick a spot with no icons or running programs). Click on Screen Resolution (or perhaps Graphics Properties, depending on the OS). Set the monitor to duplicate the screens or send data only to the TV screen.

I'm not sure if the HDMI ports will understand a computer signal. (Not all TVs can interpret the computer's HDMI signal; it is different than that of other set top boxes.) You can try the following connections.
If your laptop has a DVI output, use a DVI to HDMI cable (or adapter) to connect to the TV. Then connect the HDMI cable to HDMI 1 and use the PC audio connection as above.
For an HDMI output, use an HDMI cable. (You will still need the audio cable unless you can reset the audio signal to output on the HDMI port. Go to the Control Panel and then the Hardware and Sounds section. Under Sound, select Manage audio devices. Then in the Playback tab, make the HDMI audio the default.) For Display Port or Thunderbolt outputs on the laptop, you will need a DP to HDMI adapter.

If the HDMI port doesn't understand the computer signal, you'll need to use a converter to go from the computer's output to component video or to VGA. Then connect the converter's output to the appropriate port on the TV.

I hope this helps.

Rgb connection stopped working on laptop


Instructions
    • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
    • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
    • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
    • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
    • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.

Hi, When I connect my Samsung RF711 laptop to my Sanyo LCD-42XR9DA TV HDMI to HDMI, and source the HDMI 1 input and press OK I do not get any laptop display on the TV screen at all. I have spoken to both...


I suspect that the TV can't read the signal from the computer on the HDMI port. You would get a signal from a VGA connection. (Computers send a slightly different signal over HDMI than a DVD or blu-ray player.)

In general, when connecting a TV to a computer, turn off both devices before connecting the video cables. Then turn on the TV and set it to the source (with the no signal message). Then turn on the computer. Next set the computer to output the video on the external video port. (Depending on the laptop, you may need to enable the port in the BIOS. To access the BIOS, press Esc, F1, F2 or F10 repeatedly as you turn on the computer. The key depends on the brand of computer.) Next set the video output in the OS (depends on the OS). For Windows 7, right click on the desktop (anywhere there are no icons or running programs), select Graphics Properties and set the desired monitor choice (laptop monitor, external monitor, both or extended). Click Apply and then confirm this when the display changes. (At least this works for my HP laptop on the VGA port.; my desktop lets me change monitors under Screen Resolution.)

The manual for the TV is available here: http://www.sanyo.com.au/resources/manuals/tvs/lcd42xr9da_im.pdf .

I wish that I had better news for you.

Connecting and recording camera with s video output on 1221 tx


Hi,

The cam setup you're trying in your surgery is similar to the type I often setup in Dental operatories for there intra-oral cameras.

You need an tuner, if your external has S-Video port, you can simply plug into it and use windows media center or the cards software(if it came seperate) to record from the s-video feed.

Then you can hook the S-Video output from the laptop to the TV monitor in question and run the laptop in mirrored mode to show the same image on both screens.

Hope this helps,

Chris

HDMI connection problem


Your TV doesn't like your laptop I guess.
There should be 2 reset buttons behind your TV.
Press the reset button first.
If that doesn't work, try the system reset button next.
If that doesn't work, you'll have to call 1-800-BE-SHARP to help you with the possible software problem with the TV
Good Luck
