What Graphics card is installed? right click your desktop and change the settings there. after a clean install windows tends to only put up the drivers necessary for your monitor to work. update your drivers and then check your graphics settings plug in your HDMI port with this open and it should recognise it right away. you may also find an issue with sound after too, do the same thing with your sound mixer and make sure your tv is set as a speaker output, if this doesnt help try testing an HDMI cable that you know works fine, personally i have had to swap HDMI cables between my laptop and PS3 system one way they are great, swap them over and my PS3 wont show on tv.
can we say tempramental?
i hope this helps, if so please vote for me thank you.

You will likely need to reinstall your video drivers. You'll need to find the make and model of your video card and then go to the manufacturer's website to install the proper drivers.

How to connect Hi-sense plasma television to dell windows 8 laptop? Can Hdmcable be connected if not what are the other options?


Computer HDMI ports don't usually pass the sound from the computer on the cable. You have to use a cable between the PC and the PC audio IN connection on the TV. This is usually a 3.5 mm stereo audio cable.

How do I connect a laptop to this tv?


It will depend on the laptop's available external video ports. You can connect a VGA cable from some laptops to the VGA port on the TV. Then plug in a 3.5 mm audio cable from the headphone jack to the PC audio in port. (The audio connection is optional. You could continue using the laptop's speakers.)

Make the connections with the TV and the laptop off. You may need to enter the BIOS to enable the external video port. (It can be turned off to save power. The BIOS is accessed on boot by pressing a key (Esc, F1, Del) noted on the splash screen. For Win8 machines, you'll need to do a special restart.) Then turn on the TV before turning on the computer. The TV monitor should be automatically recognized for resolution and refresh rate. Next, if you have a Windows system, right click on the desktop (pick a spot with no icons or running programs). Click on Screen Resolution (or perhaps Graphics Properties, depending on the OS). Set the monitor to duplicate the screens or send data only to the TV screen.

I'm not sure if the HDMI ports will understand a computer signal. (Not all TVs can interpret the computer's HDMI signal; it is different than that of other set top boxes.) You can try the following connections.
If your laptop has a DVI output, use a DVI to HDMI cable (or adapter) to connect to the TV. Then connect the HDMI cable to HDMI 1 and use the PC audio connection as above.
For an HDMI output, use an HDMI cable. (You will still need the audio cable unless you can reset the audio signal to output on the HDMI port. Go to the Control Panel and then the Hardware and Sounds section. Under Sound, select Manage audio devices. Then in the Playback tab, make the HDMI audio the default.) For Display Port or Thunderbolt outputs on the laptop, you will need a DP to HDMI adapter.

If the HDMI port doesn't understand the computer signal, you'll need to use a converter to go from the computer's output to component video or to VGA. Then connect the converter's output to the appropriate port on the TV.

I hope this helps.

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.

Is the 42" philip plasma


If you really want, you can use an old CRT TV as a monitor provided you get it connected.... so your plasma... YES. If your PC has a DVI port, you could use a DVI - HDMI cable to connect. If your PC does NOT have a DVI port, you could install a video card that does... better yet, get a video card that has a HDMI port. This way, you'll only need a HDMI cable to connect the PC to the TV for audio and video.

Now i assume you have connected the Computer using a VGA cable ( 15 D pin connector )bobhifi_41.jpgbecause if you had used an HDMI cable the sound would have come by default. The VGA cable only carries analogue Video signals. So you will have to get 3.5 mm phono to 2 RCA cable to connect the sound out of the PC to the TV's audio in socket ( next to the VGA socket labeled audio IN )

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.

Step 1
Shutdown your computer and look at the rear of the case to determine the type of video connections that your machine has. Nearly all computers will have the standard 15-pin VGA output port. In addition, you may also find that your computer has an S-video port, an RCA composite video port, a set of three component RCA video outputs or perhaps even an HDMI output port.
Step 2Determine the types of video inputs that are available on your plasma TV. There should be a standard RCA composite input, a three-jack RCA component input and an S-video input. In addition, you may also find a 15-pin VGA input, a DVI input or an HDMI input. Step 3 Select which type of connection you will use. HDMI and DVI represent the highest-quality connections, followed by VGA, Component, S-video, and composite. If your computer has only a VGA output and you will not using it solely to drive the plasma TV, you may want to invest in a video card upgrade. Most new video cards will offer dual monitor connections and possibly a separate TV connection. The first monitor connection is intended for the main computer monitor, and the second monitor connection, or the TV output, can be used for either a second monitor or a TV. Depending on the card, the TV output may be DVI, HDMI, component, S-video or composite. Step 4Purchase a video cable long enough to reach from your PC’s video output to your plasma TV. If the distance is over ten feet, you may want to invest in high-quality cables to ensure that the plasma TV receives a clean signal for the best possible picture. Cables over thirty feet in length, depending on the connection type, may result in poor video performance. Step 5Set your computer’s screen resolution to something that your plasma TV can accept, using the “Display” settings in the “Control Panel” in Windows. Refer to the owner’s manual of your plasma TV for the supported resolution and refresh rate. If you are using the S-video, composite or component outputs on your computer, this step may not be necessary. Step 6Connect your PC to your plasma TV using the appropriate cable. Start the computer up and it should recognize the attached display. In the “Display” settings, you will need to configure how the plasma TV is used if it is attached a second display. Most video cards support “Clone” or “Mirror” mode, which displays the same content on both displays. In addition, there is the “Extended” mode, where the second display will operate independently, and windows can be dragged from one screen to the other. If your plasma TV is the only monitor for the computer, you will not to configure the multiple display modes. Step 7Connect a cable from the sound output of your PC to your plasma TV using the appropriate audio adapters. Then relax on the couch and enjoy your videos on the big screen.
