Most tvs can only handle a couple resolutions (ie 640x480) through the pc input. Even some HD tvs can only do 480. Check that your video is turned on and setup to the acceptable resolutions.

right click your desktop
go to properties
click settings tab
click on the 2nd monitor
make sure the box is clicked at the bottom

How do I connect my dell inspiron 1520 to my sony bravia tv


Connect a VGA cable from the video port on your computer to the video port on the Sony Bravia.
Boot up the Dell Inspirion and hold down the Fn key and press the function key that has the monitor symbol to divert the video data to the laptop video port.
Power up the Bravia and Input button on the remote and select the PC input.
You may need to set the laptop video resolution to 1024 x 768 (a higher video resolution may not display on the Bravia).

How i can connect Laptop to SONY KDL 40ex710


Assuming the TV has a VGA input socket, just connect the laptop with a VGA cable and set the resolution to equal the specification of the TV.
That will do it.

I want to connect my Compaq Presario 2500 laptop to my Sony Bravia 32s2000 tv. My laptop has an S video output for tv. How do i connect it to the PC port on the TV. It has a hd15 connector?


Does your laptop have a VGA port? if so use a VGA cable, the frequency is correct and the picture will be cleaner. The S2000 has PC input. once you have it connected, go to your control panel and select display and look for multiple monitor. It just depends on your laptops operating sys. It can be found in help and support as well. If you need further help, post a comment and I will get you the answer.

I believe the number that you have sent me is the serial number, Your TV should have a name and model #. For example (Sony Bravia model #00000) Yours would be RCA ? #?. The model number should be on the back of the TV. Is the TV an LCD flat screen? If it is and is fairly new it will have a special place to plug a PC into it. With the model name and number of your TV I can look for the manual and lok at the connection set up for your model.

'Unsupported Signal' Error indicates that TV is accepting the signals for Video but not able to display because resolution doesn't matches. Else the message would be 'No Signal'.
Follow the steps-
NOTE- Make sure cable is 15 pin(at both ends) VGA cable, working fine between PC & Monitor.
1.The standard resolution of laptop(any) which would support is 1024*768.
2. Toggle the display output from Laptop Fn Keys depending on Laptop Brand.
3. Connect the cable after settings made.
Also PC Settings will not be highlighted until connection is made.

LCD TV and VGA output


The resolution and refresh rates have to match exactly to the TV for it to work correctly with the computer.

The newer computers are using much faster refresh rates by default. Their default resolution is also different.

Consult the manual for the TV and see if the computer's external monitor output can be set to match to what the TV exactly requires. Both the refresh rate and resolution are critical.
