When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.
But once you find your dual display options you will be able to change it to make both displays the same

Make sure your TV does indeed support the resolutions you are trying to use. Some low quality HDMI cables can also be troublesome in higher resolution so try one you are sure to work.
Regarding to the desktop only being extended when using the RGB cables, try bringing up the desktop properties window, select the TV as the primary monitor and select "Use this monitor as Primary monitor". You might have to drag the windows Taskbar over to the other monitor, just rightclick the taskbar, uncheck "Lock the Taskbar" and drag it over to the other monitor.
Hope you find this solution helpful, and please rate it if you do so..

You need to press the FUNCTION key or FN key. While holding down that key, Press one of the F keys on top. The F key will have a picture of a monitor on it. Usually F4 or F10 key. So hold down the FUNCTION key and press that F key. That will display your laptop on the TV. You can press it a few time to switch between your laptop display or both.

If the Vostro doesn't read the signal automatically try to switch the signal from internal to external using the Fn (function) key + one of the F keys above the number keys. This key is usually F4 but may be different for yours. Also, make sure the input is correct on the tv....

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:
Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!
Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.
Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.
If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)
