cant get higher resolutions

I just bought a Toshiba Regza 47 inch widescreen lcd display hd tv.  I know that it displays higher resolutions.  I have a laptop that that has a vga output so it can display onto a secondary monitor.   I wanted to use the tv as a secondary monitor or main.  I can get the tv to use as an extension from my laptop.   but heres the problem My tv resolution can't go any higher than 1024 x 768.  If any higher then there is no display and my tv say's unsupported video signal.

I tried all the higher resolutions and no luck.  800 x600 works fine.

my tv has a vga input.

Would it be too much to tell us the make/model of the laptop?

HP Pavilion is the name of a range of laptops - there are currently eight different ones, so it's quite hard to tell what might be the problem.

As a general solution however, it is possible that the Toshiba only support higher resolutions in only a limited number of refresh rates (most of the normal LCD's don't need or even support refresh rates higher than 60Hz). If you attempt to use a higher refresh rate, the screen will not understand it and will instead show a "no signal".

You can change the refresh rate manually by:

Display Properties -> [Advanced] -> Monitor -> Screen Refresh rate

Start low, change the resolution up, keep going as far as you can.

Another note; some LCD televisions come with a display driver. Perhaps you need to install such thing (if your Toshiba didn't have a CD with the package, you should check Toshiba's support site if they have one available). That might make things easier (supposing of course that they do have a specific display driver).
its hp pavilion dv5000

i don't think this tv has a display driver for download and no cd came with it.   Are you refering a display driver to install onto my laptop?
seems like the laptop can't dectec my tv's ddc "Display Data Channel"
The VGA port is not capable of a resolution over 1024x768.

Sorry,

@teedjr: Well, that sounds quite interesting. Considering that at the moment I have 1920x1600 happily coming from that analogue VGA-port of mine. I never really considered the possibility that it'd be just the figment of my imagination.

@teedjr: Ok, I was being thick enough to think you were referring to the computer's end :-p
so would hooking up a dvi to hdmi cable work then?   hmm might give taht a try
sure thing, if the laptop has dvi out, a dvi-to-hdmi cable would work...video only of course.

woohooo!    its working now with dvi to hdmi connection.    yea my manual did say max resolution for vga is 1024x768.
