notebook not sending VGA signal to Samsung HDTV

Dec 6, 2008 10:48PM PST

I don't know why, but my Vaio notebook with an inbuilt geforce go 6400 gfx card doesn't send a VGA signal to my TV. The PC source in the TV menu is grayed out when connected to the notebook. My notebook recognizes the TV and if I connect another notebook to the TV first so the PC source option is available it works when I connect it after. This means that it should be working normally and that the VGA cable and the gfx card is just fine. The only problem is triggering the PC source option on the TV. Is there any way to solve this problem?

pretenderMP,

Welcome to the forum.

The first thing I would try is to update the BIOS for your laptop to the latest revision. This will reassign the pin structure in the VGA to send an outgoing "Hey, I'm here, so accept my signal" pin to access the television correctly.

Let me know if this corrects the issue.

apparently it was a common problem with Sony Vaio laptops. I indeed had to update to the latest BIOS and install some Event software in order for it to work. Happy to see everything works flawlessly now HappyThx for the suggestion

Thanks for the update.

People often look at me strangely when I suggest updating the BIOS, but more times than not does the trick.
