HP DV7 HDMI Problem


I have HP DV7 1020ea and I was using it without any problems so far. 

I have never used HDMI out before because i didn't have to and i wanted to connect my HDTV

(Panasonic Viera TH-42PX600B) and a problem occured:
I see the connection in Windows preferences it looks just as everything should work properly, NVidia Control Panel says so as well. It just looks like the screen should be a 2nd display. But it's not. Apart from what my system say there is black screen on TV, no Audio as well. 
I did some troubleshooting. I checked other TVs and the problem remains the same. Loking fine in Windows but displays  saying No signal or such messages. Next i tried updating drivers, checked on Linux, not solved still.


I bought myself a monitor 22" to extend the display. I'm using VGA to DVI connector to use it. Works fine but quality it's not the best so i wanted to check if i can do it by HDMI to DVI and it says Check Signal Cable on the screen, just like with HDVTs.


I was searching on Internet hoping somebody have simmilar issues and found some people looking for a solution and having found none. Would you please give me any help? Laptop works perfectly all the time but thats the issue concerning me and  this is a feature i need now.


Looking forwards to hear from you,
Aleksander Hudzik

Hi Aleksander,


Thank you for your query, I am happy to help!


I understand that you connected your HDTV with HDMI cable  and you had no signal on the TV.


Here are two documents that I believe will help.

Connecting a Monitor, Projector or TV (Windows 7) 

Resolving HDMI Display and Sound Issues (Windows 7 and Vista).


Please let me know if you require further assistance.

Re: HP DV7 HDMI Problem

Well, none of your links were helpful. It's some basic stuff people without any experience with computers should do when they got problems. I described my problem well enough to tell it's a connection with HDTV via HDMI cable. Can i get some serious help maybe? I lost my nerve wuth this problem so far...
