Hi there,
Please make sure that the connection is detected by your computer..go to the settings of your computer (where you adjust the screen resolution) and check if a 2nd monitor is detected (do this first before assigning the TV as your primary monitor just to ensure the connection).
If it's detected make sure that the resolution that you set is supported by the TV.
Hope this helps!

I have connected my laptop to my element tv via vga cord;sound is comin frm laptop..want the sound frm TV; THEN, I have a headset/microphone ... can I connect my headset/microphone to the TV?


If you need to get sound from your TV, you should have a sound input socket in your TV. If you have that you can connect an audio cable from your sound sound socket to your TV.
The second option is that your laptop and your TV should have HDMI ports. If its there, you can use an HDMI cable(instead of VGA cable)to connect the two. With HDMI cable, you will get both video and audio through that single cable.

Have wireless internet need to connect tv to hp laptop


If its portability and convenience you're wanting to achieve you can connect your tv to your laptop via a hdmi or vga pc to tv device such as the one below.


wireless-internet-need-connect-tv-hp-h3kz2pmtsa0m5tqtbi05zsqk-5-0_1.jpg Or you could set your close lid settings to "do nothing" when lid is closed" and set it to "never sleep" when connected to AC power and use either an hdmi cable or male vga to male vga cable to connect to your tv. You will need a wireless keyboard and wireless mouse because u will no longer need to physically access your laptop. Make sure your tv input selection is correct. For example, hdmi 1, computer, vga, and etc.

Unable to Connect Laptop to Samsung LED TV


VGA is analog - HDMI is digital
if u have a cable w/o a converter it won't work unless your video card supports digital signal output through VGA port function. Please consult with your laptop's user manual for more information.

Element tv wont see laptop


Connecting laptop VGA port to HDMI port on a TV
VGA to HDMI converter is required to connect a laptop to a TV with HDMI input. The VGA signal does not have an audio component. You need to connect an audio cable from the audio/headphone port on your laptop to the audio connector on your TV. There are HDMI converters with Audio input so you do not need to connect an audio cable to the TV. The audio is connected to the HDMI converter and then passes the audio with the video data to the HDMI cable to HDMI port on the TV. Check out these WEB site for these HDMI converters. http://www.aten.com/products/productItem.php?model_no=vc180 http://www.sybausa.com/productInfo.php?iid=1174 http://www.topbuy.com.au/tbcart/pc/Audio-VGA-to-HDMI-Video-Converter-Box-HD-HDTV1080P-p164633.htm

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.

Hi I'm trying to connect my laptop to play photographs through the TV screen using windows XP. No success at the moment. How do I connect up please? And can i get a manual for the TV anywhere...


For making the physical connection between PC and TV first we need video cable.
PC has S-Video port that should be connect to the S-Video input of your TV using S-Video cable.
Connect the computer to the TV using VGA ports or via the DVI to HDMI cable. These Macs need Adapter for a VGA cable.
RCA for audio, connect RCA to your PC and red and white colored sockets of RCA cable to TV (left audio-white, right audio-red).
In your PC open the Display Settings and activate output to the TV screen.
In your TV open the menu from that open the External inputs. And change the video to HDMI depends on the connection.
You can also change the screen resolution of your TV using the Personalize and Display Settings options in your Control Panel on PC.

After giving the connections you can watch the movies and everything is running on laptop on TV.

Sounds like your receiver only supports HDMI "pass-through"

HDMI passthrough will only forward the video signals from the source HDMI port, it will not actively convert the Component Signal to HDMI.

Why do you use VGA-HDMI cable? This TV works fine with VGA cable - it has VGA plug.
Or if your notebook has DVI output, then you can use DVI/HDMI cable and connect it to the TV to plug named DVI/HDMI (only one HDMI input is marked as DVI on TV).
I suppose that over HDMI the TV supports only some standard resolutions, but over VGA it supports almost every resolution laptops use. You can find supported resolutions for each input in the TV manual. Try setting the same resolution on the laptop.
