I connected Acer netbook (via VGA) to my RCA 42'' LCD and am only able to view the wallpaper on TV. I have tried different settings but no luck.

Go on line with the Toshiba website and look for downloads to link your computer to the RCA tv.

LOL, nope, that's the way it works. The sound will come from the netbook. If you want the sound to come from the TV you will need to run a audio cable out of the Netbook's Headphone Jack to the RCA input Jacks on the TV.

Bascially you will need a cable with a 3.5mm Stereo Male end for the Netbook headphone Jack and the other end will have 2 RCA Male for the TV's Audio Jack.

You can buy them at:

just look for audio cables
3.5mm Stereo Male to 2 RCA Male

They are real cheap 6 ft. less than $2.00, 12 ft. less than $3.50
You can get 25ft or 50ft also

According to the limited resources that I could find your only video output is a VGA port. Most newer televisions, predominantly LCD televisions will allow a direct connection via VGA. If your TV does not support VGA, can try using:
VGA to HMDI for HDTV's - Amazon search http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=vga+to+hdmi&x=0&y=0
With these I typically recommend a full force converter over a cable, but often times cables will work. Remember that with a VGA to HDMI cable only, this will only pass video and not audio. You will need separate cables for audio.
If you have a non-HDTV try this: http://www.amazon.com/VGA-Adapter-S-Video-Cable-Video/dp/B000Y7T5UU/ref=sr_1_1?ie=UTF8&qid=1315249911&sr=8-1
Use either S-video or RCA connectors to your TV.

Probably the resolution is incorrect for the extended monitor.

Hi there!

Try to use HDMI or VGA cable instead.

In order to connect your netbook to lcd tv your need a VGA or a HDMI cable( if your laptop has a hdmi port). Once you connect the netbook with the lcd tv you nned to use you tv remote to choose the input to pc or pc1 or HDMI depending the lcd tv. if you any futher questions please feel to ask.

Your graphics card on that should push that resolution so I would probably lean toward the tv. Try changing the aspect resolution or (zoom button) on the remote to change the way the screen is delivered. As long as the resolution on the laptop is a widescreen resolution and the same for the television. Make sure in your tv settings, that the aspect is set at 16:9.

you need to connect it with VGA. then enable the 2nd monitor


now you should have a wallpaper on the projector, you can drag objects to it by draging them out from the screen.

if you don't have the 2nd screen option. Then hold down the blue FN button and then tap F5 see if the picture comes, the FN + F5 will swap around with the outputs.

i dont think it has..you can then buy a VGA to RCA for the regulatr TV(should work for both the TVs)
an example is here

please info if u want more help,will be glad..regards

you should have a button that you have to press to get it to switch over, on mine i have to press and hold the Fn key then press the F4 key might not be the same on yours but you should have a f something key that has what looks like a little screen on it that is to switch the output if that does not work try hooking up your laptop just like before, and then restart it. good luck
