Question about Projection Televisions
TV isn't accepting PC input.
What I've tried.
I have connected my computer to my Samsung TV via the VGA input.
I have also pressed the Menu button and highlighted the Source option. However the PC field is still grayed out and can't be selected.
I have connected two different notebooks but it is still not working.
TV model code: LA32R81BDX/XSA
Serial no: AHCS3MKPB00502K
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.

You more than likely are not SENDING a signal FROM your PC so the option is not available. Get your computer set up for TWO displays and select CLONE if that option is available so what you see is what you get.

This Samsung LA40C350 TV requires all pins are connected from D15 D15 VGA cable
Some cables what they sell in market dont have all wires connected. Only RGB, Grounds and Horizontal and Vertical sync but missing other connections
Samsung uses those other pins detect if PC is connected or not.
Next time you buy VGA cable, take multimeter with you and check that all pinns are connected through, before buying cable.

Check this forum out - the problem is potentially due to the PC/ VGA input being set to autodetect.
