Default Nvidia drivers and sony HDTV overscan

Hi. I've been trying for some time now to use a sony HDTV as screen for my nvidia 8200 IGP. I've tried different nvidia drivers and always get to the same problem: overscan stops me using my window manager as the desktop appears cropped on all four sides. I'm connecting my computer to the HDTV by means of a DVI-HDMI adaptor.

So far I've tried all sorts of xorg.conf options, including lots of different modelines but never got a useable screen. nvidia-settings is no use either as it doesn't appear to have any overscan settings.

My TV is a Sony KDL-40W4500, capable of doing 1080p at 100HZ; (well, that's my guess, as after looking up info about this TV set but haven't found much and I don't know where to look in the manual).

Please, could someone with the same (or similar) hardware help me out?

Thanks.

Have you set the display area to "full pixel" in setup -> hdmi settings?

Post Re: Nvidia drivers and sony HDTV overscan

you should tell your sony tv to use a non-overscan mode for your computer.

it depends on the tv not on the computer.

i have a similar setup.
i have a philips 47" hdtv model 47pfl9703d.
i setup the philips to use "non scaled" mode for the hdmi-input the computer is connected.
the "non scaled" mode is namend different for different tv vendors.
some call ist "native", some "direct pixel", some "non scaled", some "true pixel", ...
consult your sony manual to find the correct setting.

you will need that setting for all HD sources to be displayed correctly.

Those TV do not do 100Hz (or 120Hz).
100Hz is just a marketing term for their motion compensation.

You're watching 50Hz content, they calculate a frame in between and they call it 100Hz.

The best the TV will take over HDMI is 60Hz.
