bryansled is 100% correct. I had the same problem, and was told by the repair shop it would cost about $500 and it was probably better to buy a new TV set. I was skeptical at first because the part costs about 150 bucks. That's a lot of money if it doesn't work. But I figured WTF, just try it. Easy to install and it worked right away. Bryansled, I can't thank you enough.

Struggling to connect my Goodmans Freeview+ HD recorder (HDMI output) to either the DVI (female) or VGA (female) input of my Samsung LE27T61B TV which is HD ready with a resolution of 1366 x 768.

They are different protocols. You have to have a converter than changes the protocol (protocol is like a needs to be translated to a different language). They are available from eBay or amazon but they don't always work very well. Best thing to do is get a unit with the correct connections.

HDMI&DVI ports already used on LG HDTV.I have X BOX 360 S,has a HDMI plug, can I use a HDMI splitter to plug in the X BOX in the DVI port ?receiving computer via HDMI now

You will not be able to split them, but they do make a HDMI Switcher, allowing you to use your Xbox 360 as number one and your PC as number 2, w you cannot mix both at the same time.

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 .

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.

How do i hook pc up to tv

Your TV will accept Component, Composite, HDMI and DVI-I inputs. Your computer will need to have a video output that matches one of those on in the list above. The DVI-I or HDMI will provide the best looking picture and is by far the most popular on modern computers. Both the DVI & HDMI jacks are for digital signals.

The standard, run-of-the-mill VGA jack on your computer can be adapted to connect by purchasing a quality cable with a DVI-I connector on one end and a VGA connector on the other. You can also purchase an adapter that will do the same thing instead for less money. If you need a long cable, purchase a quality cable instead of the cheapest one available. You will see a difference with cheapo cables. This will send video to the TV, but audio will be from the computer, unless you send the stereo signal from the computer to a seperate amplifier and speakers.

The HDMI jack will send both video and Dolby Digital audio to you TV all in one cable / connection. Of course, you need a HDMI jack on your computer and an HDMI cable to interconnect. Upgrading a desktop computer with a new video card that has HDMI jacks might be the way to go - but if you're using a notebook, this may be impossible to do.

Good luck! If my answer was helpful, please rate it "4 thumbs up." Thanks!

How do I set my Dell laptop to Samsung TV using HDMI

If you have a HDMI output on your laptop, then you should be able to plug a HDMI cable into a HDMI input on your T.V then change your input source on the t.v. If you don't have a HDMI output on your laptop then you should be able to use a DVI cable as long as your t.v has a DVI input, they also make a DVI to HDMI adapters, but keep in mind that DVI cables/adapters do not support audio.

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...

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.

Cant get hdmi to work

What device are you connecting to the TV? Are you using an HDMI to HDMI cable or a DVI to HDMI cable (or another adapter in the cable or between the cables)?

Try using a different cable. Try connecting the source device to another TV. Basically, you want to see whether the TV's HDMI input is bad, the device output is not active, or if the cable is bad (or an adapter attached to the cable is bad). Adapters are likely failure points. If you are using a DVI to HDMI cable, check your cable and device specs. Single-link and dual-link DVI are different and not interchangeable when attached to an HDMI cable end.

I hope this helps.

(some computers (esp. laptops) will have external video ports turned off by default and you need to turn them on before you try to send the output to an external monitor (TV).)

I can't play movies on my tv

Okay, this monitor setup is a little strange. There is an "AVC" component with this monitor that you use to connect everything. There is a 4 cable string (power, s-video, DVI, display port) that connects the AVC unit to the monitor. You must have all external equipment connected to the AVC unit, not to the TV itself. The connections on the TV talk to the AVC unit. I will assume you will be connecting the Blu-ray player via HDMI. HDMI is on input 4 on the back of the AVC unit. hit the input button on the remote or the TV and select input 4. There is a way of customizing the inputs to read out what you have connected to them (ex. DVD, VHS, etc.) to make it easier to use. This should get you signal from your blu-ray

HDMI Cable?

Hi CrysR,

Although you may not be able to locate a cable with one HDMI male end and one USB male end, it is possible you may find a solution with an adapter.

I recommend looking for an adapter that will accept USB input and output to either HDMI or DVI. If you only locate DVI, you can then add a DVI to HDMI adapter at the end.

Be aware with these extra pieces and signal transfers included, it may degrade the quality of your picture.

Thank you,
Go Ahead. Use Us.

No AVC media box

You should be able to use this with only the DVI connection as just a large monitor. You can use a DVI to HDMI adapter as I do believe the display is HDCP compliant. Many AV receivers will upscale to the necessary 1920x1080p resolution that the display needs.
