I can I got my dual tv to manage multiple display. GeGraphic 7300 Se doesn't support dual monitors

obvious things first. have you tried the other input plugs on the TV? do you get the same problem with plugs 1 and 2?
you can try only having the TV connected to the Graphics card and turning on the PC see if it comes up as the primary display automatically.
have you tried configuring the Nvidia setting so ONLY the tv is a display instead of dual monitor?
doing these will rule out faulty cable or faulty S-video plug or Faulty TV input plug.

1. Check the computer for changing output (some computers use <F5>, <F8>, depending on which brand they are. I believe Sony uses <Function><F7> or <F7>).
2. Check what channel the HDMI port is on (e.g. AV1, HDMI1, HDMI2, etc.) - you need to know this if your TV doesn't automatically switch to the new input.
3. Plug the HDMI cable into the TV HDMI cable-in port.
4. Plug the HDMI cable into the laptop HDMI cable-out port.

5. Turn on the computer.
6. Press the <Function><F7> simultaneously ONCE. The screen should flicker and show up on TV.
7. Sometimes you may have to go to "Display Preferences" and select Dual Monitors or external monitor if your computer doesn't do it automatically. Repeat Step 6 after.

** You may have to adjust Display Resolution to 1024 x 768 or lower in order for the TV to work. After it works at a lower display (800 x 600, for example), you can adjust the resolution to the maximum the TV can accept.

Open Control Panel - Display - Settings tab and if only one monitor screen is displayed then this laptop cannot support dual monitors.

Check external monitor settings on Fijitsu.

You must make sure it's configured correctly: make sure the monitor is up and running (not in Sleep) , that the HDMI cable is firmly plugged in (use a new one to be sure), then right click on the desktop, click NVidia Control Panel, under Select a Task expand Display and click Run multiple display wizard . If the monitor isn't picked up then go to Set up multiple displays options and see if the monitor appears in the second setting (Select the displays...) - if it doesn't then click the MY Monitor is not shown in the list option and follow the procedure to force its detection.
If even that fails then the video driver is corrupted, you will have to uninstall it, download the latest one and reinstall it.

Make sure that the cable is connected from your computer to the monitor, and if it is wiggle it and push it in all the way. If it has screws, screw them in. If that does not work, check that your monitor is on the correct input (if it has multiple) then see if anything comes on the monitor. If nothing happens you should buy a new cable from the store. If all of those steps do not work your computer or your monitor might have a more serious problem.

Please try to configure to the graphic Properties.
found at the task bar or at the control panel.
Enter to the device and set use Multiple Display.
This feature available to the Inter (R) Extreme Graphic.

i hav nv7300 gforce graphic card it is not work very well with explod pro transition why

so...
your computer don't recognize your nvidia graphic card in PCI Express slot.
you are runing now with computer's integrated graphic card?
if so then you won't have dualview option. in this case it looks for me like you've installed in the wrong way your graphic card.

your NV GeForce 7300 GS has 2 video output?
if yes then you should have the option for 2 monitors on nVIDIA control panel (i have check my nVIDIA GeForce 7600gt and in my case this option is present but is enabled only if i connect the second monitor, so try do so)

you have installed the latest nVIDIA drivers from the official website? http://www.nvidia.com/Download/index.aspx?lang=en-us

check if your video card is corect installed start/run type in " devmgmt.msc ". it will open device manager and under the display adapter tab you should see what video card you use now.

right click on the desktop then click settings.. then click advanced.. then there should be multiple tabs pertaining to the tv setting.. make sure the tuner in the card is set to the appropriate setting.. and format... usually NTSC for use with a TV a a display.. then ensure that you successfully clicked the second monitor in the display/ settings tab then check the box that say says "extend my desktop to this display " and then you tv should hav an image
