Can't get pc input to work

Hooked gateway laptop to tv with vga cable and can't get picture. Have tested cable and computer and they are working but the tv will not recognize the input. In fact, pc input is greyed out in the menu so the tv doesn't even recognize the pc input. Am I not doing something right or could the pc input on my tv be bad?

One thing you might want to try is altering the screen resolution on you laptop. If you are feeding the TV with a resolution higher than it can handle or in the wrong aspect ratio it is quite possible that it will not display a picture.

Let us know if this helps!

The 1525has a a hdmi port which you can plug a hdmi cord into. This may not support the audio. the tv and pc should detect the new monitor automatically or you may have to toggle it by hitting F4 key.

I have a s-video output and hooked it up though a cable to the yellow rca on the back of the tv. how do i get that to work and watch the computer screen on tv


1. This depends on the ports on your laptop and tv - if you have a vga port on your laptop then connect a cable to that and go to either the RGB or VGA on your TV. You can also get RGB to scart conectors so ther eare a lot of options! try your local Maplins for the cable (or look on eBay). Do a google image search to identify the connectors you have.

2. High-definition TV sets have several options of input ports and cable connections available. It's even possible to connect a computer to most HDTVs to get its picture quality. If your laptop computer is designed so it can plug into a standard computer monitor, you can easily plug it into an HDTV set, and you may have a number of options to connect it with. You must connect the video and audio separately in most cases. jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderately Easy Instructions Things You'll Need:
  • Laptop computer
  • HDTV set
  • Audio and video cables
  1. Step 1 Check the output ports on your laptop computer. There are three types of ports that can work with this connection: S-video (a circular port with pins in the middle), VGA (a square/trapezoid like port with pins in the middle and two screw pins on the sides) and DVI (a longer version of VGA).
  2. Step 2 Compare the ports on your computer with the input ports on your HDTV. DVI has the best quality, but not all TV sets will have these. Most HDTVs will have VGA and S-video (VGA has the best quality).
  3. Step 3 Connect the computer's output to the TV using the best cable connection that you have.
  4. Step 4 Connect the laptop's audio output to the TV's audio input that works with the video. In most cases, this requires a stereo-to-RCA cable, which has the single rounded plug with two black bands at one end and the red and white RCA plugs at the other.
  5. Step 5 Turn on the laptop and the computer and tune the TV to the correct input channel. Tune it to "Computer" only if you used the VGA connection; if you used S-video, tune the TV to that input channel.

Not to computer saavy so please keep it simple. I have a Sony Vaio VGC RA840G desktop with 5.1 surround sound. Also have a Samsung LN46A850 S1F HDTV. Also a home theater system. This is hooked up to cable...


From the looks of the TV manual you have everything right, so it's very odd you're running into this problem.

Have you tried swapping through the sources? I find with one of the TVs we have on display at work that any time I'm having some troubles with it I will change the source from PC to something else, then back to PC.

If that doesn't work then I'd suggest you try reseting the sound settings back to factory default. The instructions are on page 45 of the TV manual. From the TV menu select "Sound", then "Sound Reset", then either "Reset All" or "Reset Sound Mode". I would suggest reseting all.

Last option would be to try using the headphone jack in the side of the TV, though this is a last resort kind of thing since you would have to unplug it every time you wanted to use the cable box.

Hope this helps :)

Samsung TV can't detect connection to laptop


Make sure you set the laptop to display at a resolution the TV can display, it seems best to start with 1024x768 then work up.

If you are using a VGA - HDMI converter it is possible you will not get a picture.

You should be able to set the laptop to 1024 x 768, plug it into the TV, select PC input on the TV remote, and the picture should appear.

If not, then check you have the monitor output on the laptop switched on, test it with another monitor to be sure.

If all the above still fails to work, and you've checked the cable the TV has a fault.

I 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

the following connections available to connect ur computer to an TV:

S-Video output: If you have video card(external u will have this), you require an s-video cable and you connect s-video out of your computer to the s-video int of our TV.

TV-OUT: if you have video card(external u wil have this) you you require an coxial cable and you have to connect TV-out of your computer to TV-IN of our TV(it is place where cable connection goes from your cable operator)

DVI-D: if you have video card(external u will have this) you require an DVI-D cable you haveto connect DVI-D out of your computer(a white 15-pin port which looks like VGA port) ....

VGA: it is the port on your computer which is only used to connect to your computer but not to your TV or LCD(strictly)

I am trying to connect my PC to my TV. I have a Sharp HDTV and my PC is a Toshiba with windows XP. I have a componert video cable which is connected to the TV and PC. I have used Fn and F5 didn't work....


what model of TV was it please,
Does your computer have tv out video card installed?
For video to tv you will need a vga to tv converter,this is an external device and will work on the computers vga output straight into a vga input and give you 1 x vga out,1 x rca out, 1 x s/video out,comes supplied all prebuilt with onboard graphics solution. no extra power required runs straight of vga output.
Once the computers video output is established then set the TV up to tune into the converters output signal.
HD TV can be set up to run thru rca and components and if model is late enough shuld come equip with serial vga input for computers.Other than that HDMI seems to be the better quality of picture over rca component.Cost verses dollar really and function.

Cheap fix VGA to TV CONVERTER
Expensive Fix HDMI to HDMI

(it is posible to hdmi over cat5e)
NO COMPARISON FOR QUALITY.
