Hallo, i just acquired a DV7-6000el.
After the startup i made all the windows 7 updates. Then i updated all the drivers and bios from the HP website.
I connected my plasma tv, an LG 50pg1000, but i have no signal sent to it, not in extended or even in projector only mode. I tried settings both in windows display resolution and in catalyst control center.
How can i proceed?

i unistalled all drivers.
then i installed the drivers from the HP proper DV7-6000el page:
equisiti del sistema: Supported Devices and Features
AMD M880G with ATI Mobility Radeon HD 4250
AMD Radeon HD 6470M
AMD Radeon HD 6650M
Microsoft Windows 7 Enterprise 32 Edition

,Microsoft Windows 7 Enterprise 64 Edition
,Microsoft Windows 7 Home Basic 64 Edition

Then i tryed to go on the second screen by extending the screen. Nothing. Black.
If i press "detect" it finds a "visualizing device for VGA" (???)
I have in the devices both of the graphic cards and ATI high definition audio and IDT high definition audio
I can see the ATI HDMI output between the options in the playback devices (not connected)
All seems fine but no external display detected....
Anyone can help?
Thank very much

No other suggestions?
I was starting to think to make a drivers reset....
Maybe tarting from the old default drivers and try to upgrade step by step trying if maebe it works with some previous versions.
Is there any tool to completly erase any graphical drivers (for bot graphic processors) ??
