Question about Panasonic TH-42PD50U 42 in. Plasma EDTV

1 Answer

I am trying to connect my macbook pro computer to my Panasonic Viera using a VGA > HDMI converter, connected through to the HDMI port on the TV. The TV screen remains black on the HDMI setting. I confirmed that all components are working indivudally... is this an issue with my TV's HDMI input, or possibly an issue with the setup not working. How do I eliminate the HDMI port as being the issue?

On the MacBook, check the Displays pane in System Preferences to make sure the settings for the external monitor are correct. It's possible that the system is not recognizing the adapter or it has the wrong resolution setting, so it's not sending out any signal that the adapter can use.

Many of the better DVD players and high-end video game consoles use HDMI. You can use one of those as a test signal generator to check the TV.

You may get better results if you use a DVI-HDMI converter, although you would need to get the DisplayPort to DVI cable. This will avoid converting to analog VGA signals and back to digital again.

No. It is not going to work.
VGA is an Analog signal. HDMI is a digital signal, that is why you need the box, it converts analog to digital.
You can get VGA to DVI and DVI to HDMI convertors because DVI is capable of using both - depending on the type of DVI you have.

Laptop to T.V. connectivity


Hello!
This is my first time using this site, but I will try my best to assist you.
From what I understand, you want to connect your laptop display to your T.V. In turn using your T.V. as a "monitor".
So you were wondering if you could use a S400 to HDMI cable to accomplish this. Unfortunately I don't believe this is possible with that cable. To my best knowledge, S400 ports are only capable of transferring DATA between devices, not VIDEO. A VGA or HDMI cable will accomplish what you want. I don't think your laptop has a HDMI port, so I recommend buying a male-to-male VGA cable.
I looked up your T.V. and it looks it should have a VGA input port. This is what I did for my laptop and 32 inch LCD T.V. when i accidently cracked my laptop's screen.
It may not be High Definition, but you should be able to get fairly decent resolution. Make sure your T.V. is on the "Computer" input channel. (Or equivalent)
I don't recommend buying a VGA to HDMI cable converter as it usually doesn't result in improved quality.
I hope this helps! Good luck!

What kind of wire do I need to connect my samsung laptop to panasonic viera hd 3d plasma tv?


Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

WHAT TYPE OF CABLE DO I NEED TO CONNECT HP NC6400 LAPTOP TO HD TV TO WATCH MOVIE ON TV FROM LAPTOP? VGA TO HDMI CABLE? THANKS


Hi.

The best way is to get a s-video converter to connect your round s-video computer output to your HDMI port on your tv. This is the best you can do according to your laptop connections. You will need a s-video cable, HDMI upscale converter box and HDMI cable.

The other way is to plug a VGA cable to your tv VGA port if you have one.

VGA to HDMI is also possible with a converter. A standard VGA cable with a HDMI plug on the other side will not work because your computer sends out an analog video signal and HDMI is digital only.

Hope it helps!

When I connect my unibody macbook pro to my old tv using a vga to tv converter, my computer doesn't even recognize the disyplay.


When you connect your tv to your mac, make sure the cables are plugged into the TV first, and then plug your mac into the computer.
But a vga to tv converted doesn't make much sense. Your connection should be mini-display from your mac, to an adapter to either VGA, DVI, or HDMI depending on your TV connection type.

You can buy an HDMI to DVI adapter (around 20$) to connect your HDMI computer cable to your TV. You will need separates audios cables, right and left, to bring the sound to the TV.
