HELP! HDTV connected to Toshiba with VGA/RGB reads NO SIGNAL

by TMSolutions / November 1, 2011 7:47 AM PDT

HDTV - Vizio 37" - VX37L

Connected with standard blue VGA/RGB cable.

Laptop - Toshiba Satelite A305-S6905
OS: Windows 7 Home Premium (32-bit)
Processor: Intel Core 2 Duo
Display Adapter: Mobile Intel 45 Express Chipset Family (Microsoft - WDDM-1.1)

More INFO:

I have connected my blue VGA/RGB cable to my laptop at the VGA/RGB port and to my Vizio HDTV at the "RGB PC" port.

I can detect my TV through my laptop.

When I put my TV in RGB mode it displays "No Signal" and turns off after a period of time.

I have seen this HDTV used with another system via the RGB/VGA connection.

Why wont it work with mine? What can I do to make my laptop display on my HDTV?

Somethings looks wrong in that pic

To have 2 generic PNP displays is very odd. It's as if this laptop is not running the supplied OS?

Windows7 was upgraded from Windows Vista a couple weeks ago.

That's a clue.

It appears the folk that did that upgrade need to be contacted and asked to finish the install.

The generic displays is just a sign. Not a good one.

That's not really possible. Could you make a more specific suggestion? Something I could try to do myself.

Then as plainly as possible.

It appears Windows 7 is installed but all the drivers are not. The maker of the laptop must supply these or you should reload the supplied OS which had all the right drivers.

So if I went to Toshiba's website I might be able to find the driver? What might it be called? Or what could I search to find it?

Thanks for all your help!

Today's laptops are a bit hard to install Windows.

In reply to: Toshiba

For example, not only drivers from the laptop maker but in the case of Toshiba they often have the TVAP (Toshiba Value Added Package) to do things like turn on/off external displays.

I have never seem a step by step for such installs. Just guides.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
