Unable to connect laptop to HDTV through VGA.

I'll just sum up the details:
I have an HDTV which I always used to connect to my laptop in order to stream movies and games. Usually my laptop would autoscale to the TV's resolution (1360x768) and it worked perfectly. A week or so ago it suddenly stopped working, and the only resolutions it will accept (the TV) are 800x600 and 1024x768. My laptop also stopped auto-connecting to the TV, but I didn't upgrade my drivers or anything like that.

When I select a resolution > 1024x768 and go to my TV (FN+F8 combo) it will just say "Mode not supported".
Now, I checked the manual, and from what I could gather I'm suddenly on VESA GTF instead of VESA (see this image I got from the manual: http://img388.imageshack.us/my.php?image=samsungresolutionvgaab5.png)

System:
Samsung LE26S81B
VGA Cable and 3.5 Mini-Jack
Dell Inspiron 6400 with Geforce 7300 Go

A big thanks and points for whoever helps me! :)

Check the connection with a computer monitor - you need to determine whether it's your laptop or the TV that changed.  Next, a 1360x768 resolution should appear when you try to configure the resolution for the external VGA port - if it doesn't, your driver may have changed or been corrupted, even though you didn't purposely update it.

I tried connecting it to a normal monitor and it all works fine.
When I choose the resolution for the external connection my TV gives me the "Mode not supported" error.
>I tried connecting it to a normal monitor and it all works fine.

That indicates that the problem is with the TV.  The port may have been damaged by a surge, and you'll have to get it repaired or use a different port.
Argh, I hope someone can still get me a fix because I want to keep that as a last resort :S
If the monitor worked fine, then I'm afraid you're going arrive at this conclusion eventually.  The laptop sounds like it is working normally with it.
Ok, I got it to work for a minute, but then for a reason my driver did something wrong and it got messed up again.
I think the combination Nvidia control panel & FN+F8 combination messes something up, and I'm 100% sure it's not my TV.
Anyone got any ideas to configure exactly what the FN+F8 combo does and disable Nvidia Control panel's domination?
The only way you can be 100% sure it is not your TV is to try a different computer with it.  There is a small possibility that the laptop and TV combination don't work together, but it is a small possibility, and I would not jump to that conclusion without testing the more likely possibility that the TV is broken.

Fn+F8 typically switches between your laptop screen only and having the external VGA port turned on - this is manufacturer specific.
I tried connecting my main PC with a DVI -> VGA connector and it worked, gave me the right resolution and everything but it's just not easy to control that way.
Next I totally uninstalled my drivers and reinstalled the ones from the Dell website and it works (kinda), the only problem is that for some reason windows detects the external monitor as inverted (vertical resolutions like: 768x1024, 1024x1280) and I have no idea how to change that.
I'm positive that once I get that fixed everyone will work.
Try Powerstrip http://entechtaiwan.net/util/ps.shtm and see if setting the correct resolution (1366x768) makes the TV recognize it.  If it does, then we will know the hardware is ok on the laptop and the TV and the next step is to get Dell's drivers back to working order.
I got it to work on my own after editing some driver files.
Thank you for your help, but it seems none of the solutions helped.
You should post what you actually did - "editing some driver files" is not specific enough to help someone looking for a solution.  If you don't know exactly what you did, then this question should be deleted, instead of a comment accepted as a solution.
