Since you don't provide the laptop model, I assume your PC has at least a 15 Pin VGA connector. You will need a 15 pin male VGA to 15 pin male VGA cable, just plug it at the laptop and the monitor, that should do. If your laptop has also an HDMI or DVI or Display Port, you will need a proper cable or adapter.
The video port on a laptop is a 15 pin DSub connector. Connect the VGA cable from the projector to the 15 pin video connector on the laptop. power up the projector first then boot up the laptop and the video output from the laptop will automatically divert to the projector.
if your pc has hdmi out - the you use a hdmi cable from the pc to the tv on one of the hdmi inputs.
if your pc has a 15pin vga cable you can unplug from your PC monitor (or go buy a VGA cable if you want to keep one on the tv and one on your pc monitor - or if you are using a laptop).
when you unplug the computer from the monitor .. check the pins - should look to be about 15 pins in the connector. it that will plug into the tv- then you are using a vga cable. if it will not plug into the tv pc input .. don't force it. It could be a dvi connector . .take the cable off the PC and to radio shack and they can fix you up (you need a dvi to vga cable - not likely, but possible)
I always turn off a pc before disconnecting monitors - and plug into the other display before turning the pc back on.
Use a 15-pin, male-to-male VGA cable to connect your laptop to your TV. male-to-male means the pins are sticking out on both ends. Since both ends are male, you'll need to find the female VGA input on your laptop and on your TV. This is often called the PC input. Now, connect one end into the TV and one end into the PC. On a Mac, the VGA input is conveniently labeled with a "display" icon. It's recommended that you do this with everything powered off.
yes sir..i think you must looking and buy VGA adapter 15 to HDMI complete with the HDMI cable set. you can find this adapter at the computer spare part store or electronic part store. not cheap but very usefull for you in the next day. is very easy to connecting...plug you adapter to the output VGA VAIO.. connect the HDMI cable to adapter (like USB) and the rest to the input at your samsung lcd...good luck..
Atlast I got some help from the right people (Samsung)! I would like to share it with others facing the same problem:
If you are using the D-sub 15 pin jack (VGA Monitor Cable: make sure its 15 pin and NOT 14 pins), follow these steps:
Make sure your TV and computer are off.
Using a 15 pin D-sub (standard) video cable, connect the Video Out jack on your computer's video card to the PC In jack on the back of your TV.
Using an audio cable with a min-stereo plug on one end and two RCA jacks on the other, connect the Audio Out jack on your computer to the left and right PC Audio In jacks on your TV. (Note: If you have your computer connected to separate speakers, you can skip this step)
Switch on the Notebook and Adjust the Resolution (800 x 600 pixels would do). You can go to Control Panel and Adjust the screen resolution. (Keep ‘Screen Refresh rate’ at 60hz in the Monitor Settings)
Switch on the TV and try to Select the Source as 'PC' (you can do this by either pressing the 'Source' button several times on your TV remote or go to the Menu - Setup and Select the 'PC' as source there).
In most cases, after following the above steps, the TV would start to show 'Auto Adjusting' message and it will start showing your Desk top on the TV. But incase it doesn't work, you can do the following:
a.Mostly the problem lies with the VGA cable. Make sure you have the right one (15 pin) and its securely attached at both ends. If you are not using the right VGA Cable, it means that there is no connection between your TV and Notebook. Your TV will show 'PC' in Grey in the Source Input list (Go to ‘Menu’ from the TV remote). b.Both your Notebook and TV should be switched off when you are connecting the cable otherwise one of them might have a problem detecting the other one. c.Try Pressing Fn + F5, F6, F7 (depends on which Notebook brand you are using) on your Notebook several times. At times, you will see some signs that the Notebook and TV are trying to connect. Select 'CRT' from list of displays available to you.
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.
