Help with HDMI output

[whoopiedoo]

Back when i had Windows Vista in late December of 09, I wanted to test out my HDMI output on HP laptop. It worked perfectly, i was able to play HD videos off my computer and it would play through my HD Toshiba TV.

But now that i have upgraded to windows 7. (which i did in the first week of January) I cant seem to connect my computer to my TV. Nothing happens. I don't know why it's doing this.
When i plug the HDMI cord into my pc, my screen turns black, but nothing shows up on my TV. It just says "No video signal."

And i dont know if this helps, but my graphics card is: NVIDIA GeForce 8200M G

Right click on your desktop and go into your Nvidia Control Panel.

From there you should be able to set up the TV as the display. You'll probably have to do this before you connect the TV to the laptop.

Or, you might need to right click on desktop and go into "Personalize". Then click on "Display Settings". Then click on "Monitors".

Thankyou for replying.

Im not exactly sure what setting to modify or even how to set up the TV display in the Nvidia control panel.
Also, i cant locatre the "monitors" page in "display settings."

Click on Advanced Settings after Display Settings.

I think the setup of the settings and control panel may be slightly different on a laptop. I'm on a desktop so it's kinda hard to give complete instructions on this, but I know that one of the two methods is how you get to the settings that allow the TV to be used as the display.

Sorry for the lack of instruction on my part. Maybe someone with a laptop that has done this before will be of better assistance.

The only settings to change is for my laptop's monitor. I think I would be able to change/set up the settings for the TV if i were to plug in the HDMI cord in the computer. The problem is that my computer turns black whenever i plug the HDMI cord in. I even try using fn-f4 and window-p, but it does nothing.

I'm a little confused on this problem.  HDMI is HDMI.  It is a standardized set of protocols and pin outs and it shouldn't be different from OS to OS any more that VGA should change from one OS to another.

My WAG is that something else is going on.  Bad cable, bad connector, bad port, etc.

Well it has to be one of settings on my computer.
I was able to get my computer to display now without that black screen when the hdmi cored is plugged in.

I have both the tv and computer set at the same resolution. (1366x768)
When i click on "Connect to a projector," my desktop still doesnt show up on my TV. I've tried it on both duplicate and extend.

I havent tried connecting it with another computer (cause i dont have another one)
But the cable is in working condition, it works with my bluray. plus the ports seem to work fine, my computer detects that it's connected to my tv.

I don't think the HDMI cable or the type of cable is the issue. The problem is that there is no signal to the TV from the laptop. It used to work, but after a install of Windows 7, it doesn't work anymore.

Try this whoopiedoo, if you haven't already...

1. Connect PC to TV via HDMI. (You said you can do this without getting a black screen, correct?)

2. Click on "Connect to a Projector or other External Display".

3. Choose the display configuration desired.

4. Activate the output to the TV. (screen may go black)

5. Shut down PC, but leave the everything connected, and leave the TV on.

6. Turn PC back on, and see if a display pops up on either screen.

If you turn the PC back on and at least get a display on the PC, this will allow you to make the adjustments to the PC settings. If it automatically displays on the TV, then you're good to go.

Still nothing on the TV

Is the PC recognizing that an external monitor is connected after performing the above steps?

What is the model # of the HP laptop?

[whoopiedoo]

Yepp, it recognizes it.

The model number is: HP G60-445DX

I've got the exact same issue with the same laptop... so I am going to give this a BTT
