Hi.

You do not need to connect two video cables, connect just one. Also if the computer and TV have both ports, bette using an HDMI to HDMI cable, rather that HDMI to VGA. You will need to connect sound cable along with video cable from computer.

On the TV ensure that you have selected the source. The TV does not automatically pick the source from VGA or computer HDMI. Use the source/input select button to locate the source.


On the computer ensure that you have enabled the external output. On laptops you often need to use a function key. On all Windows computer you have a control of connected monitors in Display Settings (personalize in Vista and 7).

Guys, Recently i got LG 22" LCD TV. It has VGA port and HDMI port. When i connected my CPU cable toLCD via VGA port it didn't show anything, :"( i checked input MENU on remote then it shows only 4...


HDMI [High Definition Multimedia Interface]. VGA [Video Graphics Array]. AV [Audio Video]. By these definitions itself talk to you about the inputs your TV have; and it do not support VGA. Output from PC is VGA. Without a VGA input with the TV, you can't connect the PC to TV. I think I'm clear. http://electronicshelponline.blogspot.com/

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.

I want to use my television as a computer screen. How do I switch the television to proper mode?


Look for a button on the remote or the TV itself labeled Source or Input. This should let you change the input between TV, AV, HDMI (on some TVs), and PC. Just press the button repeatedly or use the up/down arrows.

Before setting the input to PC (VGA), turn off the TV and the computer. Then connect the VGA cable (M-M) and the audio cable (a 3.5 mm M/M cable, if you plan to use the TV speakers) between the two units. Next turn on the TV and set the input to VGA. Then turn on the computer. (This is if you are using the VGA or D Sub 15 connection.) For a desktop, if you do not have another monitor connected, the TV should automatically be detected and the resolution set with any Windows OS (XP and later). However, you may need to reset the resolution and the refresh rate. For Windows 7, right click on the display and choose Screen Resolution.

For a laptop, you may need to enable the video port in the BIOS. Accessing this depends on the manufacturer of the computer motherboard. (Often Esc, F1 or F2 is the key to press after turning on the computer but before the OS loads. This can be tricky to time correctly.)

With a laptop or a desktop with another monitor attached, you will need to tell the computer how to deal with the multiple monitors. (Extend, monitor 1 only (or laptop internal monitor), monitor 2 only (external monitor), or dual display.) For my HP laptop with Win7, I choose Graphics Properties instead of Screen Resolution. There may be a keyboard Fn shortcut to access this.

Some TVs will accept a PC signal on the HDMI port (directly from an HDMI port on the computer or via a DVI to HDMI cable). Not all TVs do this. (Without the model for your TV, I can't confirm if this will work. If it doesn't, it is because of the differences between the PC output signal and that of set top boxes (cable or blu-ray players).

I hope this helps.

Second look for HDMI port at the side of your laptop. (It may not be the model of your laptop.)

Third look for the HDMI port on you T.V. (It may not also the model of your T.V.)

After confirming those connection on your T.V. and Laptop, you can just the HDMI cable to connect you Laptop to T.V. Also you need to choose HDMI on your T.V. settings and for your Laptop you can just switch the display by pressing FN+F4 or F5.

Hope It helps.

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

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!

How do i connect my adventt9101 to my sony lcd tv, i want to use hdmi leads but i dont think my pc has hdmi port? any help


If you don't have an HDMI connection on your computer, then you will need to get a VGA cable. There should be a VGA connection on your tv. Just disconnect the monitor on your computer and connect the VGA cable from the computer monitor port to the VGA port on the tv. You may have to set the tv for PC or Aux input. You won't have high definition or sound to the tv with a VGA cable though. The sound will still come through your PC speakers.

Can you connect a acer aspire one to the tv via hdmi


You cannot connect your acer aspire one via HDMI as its not having HDMI port. But you can connect via VGA cable and most of the TV supporting HDMI will also definitely support VGA input.
