Pavilion DV7-6000el and no HDMI on Plasma screen

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?

Re: Pavilion DV7-6000el and no HDMI on Plasma screen

i unistalled all drivers.

then i installed the drivers from the HP proper DV7-6000el page:

Rebooted

 

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"  (???)

notes:

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

Hi, it might be your cable if it's not of good quality and also have you tried connecting via windows mobility center ?

 

If you know someone who has a hdmi cable that works ask if you can take your laptop to their place to connect to their, once you tried the windows mobility center

Unfortunately the laptop mounts windows 7 home premium that has not the mobility center feature. About the cable i tried several ones. My tv (Plasma LG 50pg1000) has HDMI 1.3, btw

Re: Pavilion DV7-6000el and no HDMI on Plasma screen

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) ??
