Can't connect 42PFL6705H/60 and GeForce 9800 GT via HDMI

PC with GeForce 9800 GT,
last version of Nvidia Control Panel from official site,
Windows 7 Max x64,
TV Philips 42PFL6705,
Cable HDMI-HDMI.

There is no second monitor in the screen resolution settings. Nothing also at Nvidia Control Panel.
TV says "No video signal".

Also I have a notebook with HDMI - they work properly right away.

If I disconnect the VGA-monitor from PC and start only with HDMI to TV, then TV display the BIOS-screen and the first part of booting (until "Welcome" screen).
Also all work properly in Windows Safe-mode.
So, the cable, TV and video card is functional. The problem is in the graphic settings, but where?
Sorry for my English and thanks for your answer!
