Duplicating the display is usually not possible as the PC display is one resolution and this looks to be 1920x1080. There are reasons for the TV to not show the PC input on Samsungs. Here's a video about pin 10.

That's one of the hurdles. The next is that resolution issue when duplicating a display.
The final hurdle is that many PCs don't have the vga output enabled. This is non standardised so we're hunting for details or a product manual.

I have a Samsung TV Model # LN-T4065FX/XAA. I have connected the TV PC Input to the VGA port on my PC. When I go to setup the TV for the PC, it is not highlighted and I'm not able to set it for the PC. The TV is connected the HDMI is also connected.
Also, I am able to set up my PC for duplicate, so both the PC monitor and the TV should be displayed.
Thanks for any help you can provide.
Thanks a mil, Uncle Dewey
