[RESOLVED] Display says Sony 72" is actually Sony 46"

I am new to Linux. I am looking to get rid of Windows. Zorin seems to be it...
System:
Dell Optiplex 780 Desktop Core 2 duo 3.1
4gb Ram
Zorin 12.1 x64 is the only OS installed on 80gb HD
Default chosen for partition install
Internal graphics used - Q45
Internal Audio chip used - Works ok
Zorin runs fine in Live and also while installed on the HD via a 19" Dell display.
Zorin-OS-12.1-Core-64.iso
Display is Sony Bravia KDL-46Z4100 46"
I have connected the Dell 780 via the second display port only ( Single port used) with a DVI to HDMI converter to my Sony Bravia 46' television HDMI input. It works fine however, it sees the tv as a Sony 72" television and not a 46", hence the edges of the screen display are outside of the visible tv screen. For example the menu is below the visible display.
It reports the resolution correctly as 1920x1080
I have updated software via update
Is it possible to get the driver to recognize the TV as a 46"?

Any help is appreciated.

Hi, can't find ubuntu related issues but found this:

https://community.spiceworks.com/topic/ ... re-correct

one of the posters mentioned turning overscan off? Another changing the format of the screen?

Hope the answer might be in the thread somewhere?

That's it..
After spending the better part of 2 days looking for a solution I told the Wife we had 2 choices.
1. Continue with windows - I don't think the forum rules allow me to show that response.
2. Get a 72" TV - I was sure someone would confirm it

Unfortunately, the bravia has an option to set the "Display Area" to "Full Pixel". So now the display is correct.

Thanks..

Woohoo!
