Hello all,

First off thanks for taking your time reading this.

All help is much appreciated!

The OS is Vista and I have dual Nvidia 9800gt's in sli mode on my Asus Sriker II extreme motherboard.

Main display is BenQ W2400 which is working well.

I had my Panasonic TH42PZ85 connected as the second monitor earlier and it was also working good via the dvi->vga setup.

Recently my hard disk went bang and I did a clean install on vista.

I hooked the TV on to my video card and nothing.

Vista and nvidia cards didn't even seem to detect my plasma tv.

A hundred restarts later a second display "generic non-pnp display" appeared in my device manager and an "Analog Display" in the Nvidia control panel.

I was overjoyed until i tried to extend my desktop...nothing.

The tv's sync method used to be set to "H & V" when it was working well, but now the TV doesn't even detect the signal when I try this "correct" sync method.

Setting the sync to "On G" displays a horribly distorted greenish and flickering picture which has parts of my background image.

I've battled with this thing for 2 days straight now, so you can imagine how grateful I am for all advice.

Here's a list of things which I have already tried (each a dozen times):

Manually changing the "generic non-pnp display" to "generic pnp display" in device manager. Didn't help.

Changed my dvi->vga setup to dvi->hdmi setup. Didn't help.

Uninstalled all previous drivers and cleaned after them with DriverSweeper. Tried this procedure with 8 different versions of the nvidia drivers. None of this helped.

Disabled sli, didn't help.

I've played with all possible refresh rates and resolutions, nothing helps.

The whole setup is:

q9550 cpu

Asus Striker II Extreme

2gb ram

2x Gigabyte's 9800gt

Vista Home Premium OS

BenQ W2400 TFT screen

Panasonic TH42PZ85 Plasma Flat Panel TV
