Unable to display PC screen on TV using VGA cable

I have a Samsun Plasmag TV (PN50A550) that offers PC input via VGA. My HP notebook computer (Pavillion DV9727) has Vista Home Premium.

I cannot get the HP notebook to display the screen contents to the TV unless Vista is in Safe Mode. When Vista is in regular mode both the notebook and TV are completely black or the TV indicates "Mode not supported".

Using a Dell notebook with XP Pro, the TV's VGA input works flawlessly. Additionally using a 19" external monitor the HP/Vista notebook works flawlessly.

Any suggestions would be appreciated. Thank you.

How to connect laptop to my tv


The only output you have on this laptop is a VGA monitor connection.

See manual.

You need a TV with a PC connection to view the video.

You will also have to connect up the speaker sockets t the TV audio in via a cable, that depends on the TV.

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.

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.

I am trying to connect an acer one notebook to a beko 32" flatscreen and everytime i plug the vga lead in the laptop screen goes black an the tv says no signal,,what am i doing wrong??


It could be a no. of things:

- Wrong input selected via the TV
- The VGA input on the TV is turned off
- Problem with the VGA cord
- Problem with either VGA port

there the basics, if there all great and it's still no working, try setting your Computer display to EXTEND rather then projector only, then play around with your graphic output settings.

UPDATE all your Drivers and check all your cables. PLUG IN YOUR LAPTOP, yes it will make a difference to the way the graphics card operates.

Hope this helps.

Want to connect my Sony vaio VGN-A250 to Sharp 19'' LCD TV


Your laptop will have a VGA output or possibly a S-video out. For the VGA you'll need a standard VGA cable. Plug the cable in to your laptop and the PC input of your TV. If your TV does not have PC input it may have a DVI input. IF it does you can use a VGA/DVI adapter to plug it in. If it doesn't have a DVI input you can use the S-Video output on your laptop with a standard S-video cable. After the connection to your TV is made you will have to toggle alternate display by pressing and holding your [Fn] key and pressing F4, or F5, or another F# key. It's the one that looks like a TV screen. Press once to turn on output, press again to turn off your laptop screen, press again to go back to laptop screen only

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.

Samsung LCD TV not receiving PC signal


Check your vga cable. Some cables have only 14 pins, some have all 15. The missing pin is pin 9, in the 15 pin cable it carries 5v from the graphics card to the screen. Without that 5v signal most LCD and Plasma television screens won't recognise a PC input. I had the same problem and only managed to fix it when my girlfriend swapped a cable over for me and as she did so glanced inside and said "it's got a bit missing" The cable that came with your PC most likely only has 14 ins as that is all a monitor screen needs.
You can buy a 15 pin cable at most PC or electronic shops, just check that isdoes have all 15 pins befiore you buy it. The cheap ones are just as good as the expensive ones unless you are buying 20 foot cable. For 6 foot cable the cheap ones are just as good as the expensive ones.
