Nvidia 9200 in PC connected to Samsung HDTV by HDMI does not display

Hello,

NVIDIA geforce 8200 does not detect LCD HDTV PC connected to Samsung LE46530F1W by HDMI

The PC is running Win 7 Premium Home 64 bit SP1. It is connected to a 19 inch monitor (Viseo 190W) via a vga cable. The monitor is at 1366x768 at 60HZ.
The nvidia driver version is 275.33.
The tv is a recent Samsung LE46530F1W and is connected by new HDMI cable from PC to TV.
The TV reports that this source is not connected. The current resolution of the TV is 1920x1080 at 50HZ.

If I look in Nvidia control panel, under 'setup multiple displays' - I only see the Vi##SPAM## 190W as a single display. I choose 'My display is not shown', followed by 'Rigorous Display Detection' and 'Yes' to 'Would you like your TV enabled'. This puts a 'tick' in the 'force television detection on startup' checkbox. The 'restart now' button is greyed out - I restart the PC anyway, without effect.

The TV does not recognise it is getting a signal from the PC. The PC does not recognise the TV display as existing.

Any advice would be welcome as to:

Am I posting in the right forum?

What should I do to make the TV display my PC output?

I would recommend you to connect the TV alone and check if there is any display or not.

Thanks Champ 2010,
the tv works with Freesat on HDMI1 and Playstation on HDMI 2. The PC is connected to HDMI 3. Since I posted the original topic, a couple of reboots of the PC and the TV means that we can now see 2 displays in Nvidia control panel. Unfortunately, we can only see the windows desktop wallpaper on the TV now - not any icons, taskbar or programs.

any further advice very welcome

Hi - eventually resolved by right click on the display in nvidia control panel and choose DUPLICATE DISPLAY instead of EXTEND
