They both have to have the same type of connection such as VGA or HDMI
or connect a cable between them otherwise you will need some type of
interface between them to make the connection.
Once you have
the cables connected, get the tv remote and press Select Input to tell
it where the signal is coming from (PC, VGA, HDMI). Reboot the laptop
and the image will appear on the tv.
The video will show on most systems when you
reboot without you having to do anything. Some systems will require you to hit
the FN (Function key) + F1 thru F12. Hold down the FN key then hit the
correct key for displaying on the monitor (F1 thru F12). The correct key
will normally have CRT/LCD on it or it will have the icon of a display.
You will need a cable that connects the tv to the pc. If you pc has a vga connection and your tv has a vga connection, then you would purchase a vga cable and connect it. If the computer and the tv have 2 different types of connections you will need some type of adapter between the two of them.
Once you get them connected with a cable you just turn the tv on and Select Input (Select either PC, Computer, HDMI) of where the tv should receive the signal.
On the pc if you just reboot it most times the image will appear on the tv. if not you can Press and Hold your FN function key at the lower left portion of the keyboard then hit the correct F1 thru F12 key that toggles the display. The correct F1 thru F12 key will have LCD/CRT on it or it will have the icon of a display.
1 - the cable you are trying to use will not work - the RCA inputs in your tv can't accept the signal coming from the VGA. To connect the laptop to a tv the tv must have an VGA input, nothing else will work.
2 - When you start the laptop with an external device (such as an external monitor or tv) attached and turned on, the image may appear on either the laptop's display or the external device. Press to switch the video image between the display only, the external device only, or the display and the external device simultaneously.
Check refresh rate and setting for external display output. It won't work with unsuitable screen resolution, color depth or refresh rate. Check all three points and I believe you can troubleshoot the problem this way.
The DV6000 has all the drivers needed to connect to a TV as long as the TV has either a s-video connection or a pc vga input. The vga input is usually blue in color on the tv but on the laptop it may appear dark tan or brown and does not have screws to hold it into place, the plug just fits in and tension holds it in place. Once you connect the cables, change the input on the TV to the type of cable you are using. The laptop should automatically pick up the signal from the device and load the driver for it. The desktop should appear on the tv if the output signal and input are matched. The icons may appear different on the TV if the resolution is not close to a match but that should not be a concern unless it is cutting some of the picture off, in that case all you have to do is change the resolution to one that is easier for the tv to show. The dv6000 allows you to toggle through the video output settings by holding down the Fn key and tapping the F4 key, this will change the display to both laptop lcd and tv, just tv, just laptop lcd etc. It will even let you extend the desktop from the laptop to the tv or from the tv to the laptop, making one long display side to side.
Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.
Perhaps these simple trouble shooting procedures will get the job done.
1. use the DVI to VGA adaptor that came with your card
Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary
2. plug in the your LCD monitor on Secondary Display port using your DVI cable
At this point you should be able to see your desktop on the Primary CRT Display
3. Go to the display properties and use the Nvidia Dual Display Setup Wizard
set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel
If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )
At this stage both displays should be showing a Windows Desktop
If you now see your desktop on both displays , you can now put the LCD on the Primary Port
No Signal Detected ( this means the display device is not receiving a signal )
If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.
If you are certan you have done everything correctly but still see only "No Signal Detected"
