Tip & How-To about Televison & Video

Trying to connect computer to LCD TV and get no signal?

Hi.


If you are trying to connect computer to LCD TV and get no signal, as a first thing do the following:

Double check cable and connection. If possible test different connections. Try using VGA, DVI or AV, depending on availability on computer and TV.

Ensure that Video drivers on computer are properly installed, and that the video adapter is working properly.

If you are using a laptop, ensure that you do not need to use a function button to enable the external display, this is pretty common on laptops.

If you are using a desktop, go to display properties, find the windows where you get the picture of two monitors, and ensure that both monitors are enabled.

On Vista try also using the 'Identify Monitor' button on Top. It is located on same properties panel as the two monitor, the main Display Property windows. From the same window you can also modify display resolution, as explained later.





If still no luck, then it may be a problem of synchronization between TV and computer, in that case try the following.

  1. Turn off TV.
  2. Disconnect TV power cord.
  3. Restart computer.
  4. With Computer already on, plug back and restart TV.


....If that does not work.


On computer, go to display properties.

First try changing computer resolution. The TV max resolution may not be available on computer. In that case try lowering down to the smallest 16:9 resolution available on computer graphic settings (usually LCD TVs are 16:9), and if that does not work, set resolution to 800x600, just to test (picture proportion will be distorted, or you get squared box on a 16:9 TV).



If that does not work, open Display Properties. In Display Properties access Advanced, and then Monitor settings (XP). On Vista choose Personalize in control panel, then Display Settings, and go straight to Monitor Settings, in there again go to Advanced.

Under the advanced monitor settings you will find a tab called monitor, in there you find the monitor frequency. Try setting this to 50Hz, if that does not work try 100 HZ, that is the output frequency of your TV. If you get unsupported frequency, revert value to normal.

I am trying to connect my LCD Hi-def television to my computer so I can watch internet on my tv. The tv is showing "invalid signal". What is this and how do I fix it? I have the dynex DVI-D to HDMI Cable and Mac converter.


Hi,

You can only use your TV for viewing internet from your computer by using the TV as a PC monitor. To do this you should connect your computer to your TV using a standard VGA cable - the same as you would use to connect your computer to any other external monitor. You should note that this cable doesn't carry a sound signal so you can't use the TV speakers for sound output.

However, you can connect an HDMI cable from your computer to your TV to play media files or DVDs. This cable does carry a sound signal so you will be able to use your TV speakers here. This cable cannot be used for turning your TV into a PC monitor.

And all of above shouldn't be confused with "Internet TV". This is something totally different and requires your TV to be connected directly to the internet.

Hope this helps.

Hello i have an hp pavilon dv6000 laptop and connceted to my lcd tv without any problems,3 days ago it was disconnceted and the cable was complitly out of work,i bought a new HDMI cable now,but it shows no signal on my the tv screen. thanks Faraz Fathi


The first thing you can try is, connect the LCD Tv to another computer with the HDMI cable and verify it's working that way on the other pc. If it works, then the HDMI port on the Laptop might have a problem which will require Service. Troubleshooting and TIY will not fix the issue.

If the same LCD TV doesn't work on another computer, then double-check the cable and the connection. You'll be able to narrow down to the culprit and may need another LCT TV.
Is the LCD TV still working with other connections? like with your DVD Player or Cable.

Let me know the outcome.

Good luck.
Thanks for using FixYa.
