Re: connecting my laptop to my tv

I have exactly the same problem with my Sony Vaio. It seems to be a problem with the graphic board. Samsung needs a special signal over vga to unlock the PC-mode. There are only few Laptop graphic boards which send this signal on startup.

I haven't found a solution yet. But you may try to get a newer driver from:

Please tell me it worked out for you.

Re: connecting my laptop to my tv

I think u guys need to connect the laptop to the tv with the laptop off. and pc mode should come up when ure changing sources. then u should be able to just function F6 or whatever it is to put it on screen. im currently looking foor an answer to why it does not just got pc mode without me doin this? im lucky as i have my pc tower sitting next to my tv so i can just plug it in and then switch it to the laptop when ive got the tv in pc mode. but it gets annoying so if anyone knows how i can configure the tv to just switch to pc mode even if nothings connected that would be great.

I have a relisys lcd tv and its connected to the hdmi output mode but i want to connect my computer to it using a vga cable and once i plug it in nothing happens and i cant change the mode of the tv

if you have a PC input to your LCD panel, connect the VGA cable at both ends (one to PC and the other to LCD TV), Only after the connection switch on the PC not before.
Make sure your Computer Display settings - Resolution not more than 1020x780. If so reduce and then try.

Samsung LN-T4661F will not display PC; displays 'mode not supported'. Using a VGA cable to connect laptop to tv

Look in the manual for the TV and determine which platform is supported. VGA, XVGA, SVGA etc. Set your computer output to the proper mode and the unit should work. Let me know how you make out.

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:
  1. Make sure your TV and computer are off.
  2. 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.
  3. 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)
  4. 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)
  5. 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).
  6. 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.
