Nvidea GT 430 hdmi to LCD TV: Outer edges always cut off (outside display area)


I've been having some trouble configuring my Nvidea GT 430 with my LCD TV. When I specify the larger resolutions like 1920x1080, there is always one inch trimmed off around edge.

First using Linux Mint 10 LXDE, I booted with the new graphics card in. Without loading any drivers, I was able to select 800x600 or 640x480 and those had an inch of black around the screen. I installed the proprietary Drivers and then the screen was cut off a bit on the edges and the text was so tiny i couldn't see anything.

I then tried Linux Mint 11 Gnome. The text was readable, but still couldn't get the screen to match the TV edges correctly.

I think it is a problem with my TV as this happens in windows and Linux. My TV is older and doesn't allow me to resize the screen within its menus.

However, in windows I am able to use the Nvidea tools to resize my resolution to a custom size. It turned about to be about 1800x1020. I only really like using windows unless I absolutely have to though..

Is there a way to manually resize the display area in the xorg.config file? or any other workaround?

I would prefer to get this working with LXDE~

Thanks in advance

Use the Nvidia control panel. There's an option for TV over scan. Once you adjust this setting, it is auto-saved to ~/.nvidia-settings-rc. Each time you re-launch the Nvidia control panel the previous setting is applied. Or you can apply the settings with nvidia-settings -l.

To apply the setting perminantly to xorg.conf, explore the --tv-over-scan option for nvidia-xconfig.

nvidia-settings --help
or
nvidia-xconfig -A
or
each tool's man page
or
Read the online Nvidia documentation - which is also installed locally with a proper driver installation.

Quote:
The "TVOverScan" option can be used to enable Overscan, when the TV encoder supports it. Valid values are decimal values in the range 1.0 (which means overscan as much as possible: make the image as large as possible) and 0.0 (which means disable overscanning: make the image as small as possible). Overscanning is disabled (0.0) by default.

At first, I plugged only my HDMI cable into my TV. For some reason my fonts would get too small to read and the edges were outside the TV screen, making it nearly impossible to get into the menus.

After some fiddling, I connected the DVI cable to a LCD monitor, and the HDMI cable to my LCD TV. The fonts were now readable, and I was able to make good use of Disturbed1's info~

Thanks Disturbed1, that info got me right on track. However, the option that I needed to adjust turned out to be OverscanCompensation. I could change it by dragging the bar within the nvidia-settings gui.

That setting doesn't stick after reseting X (lxdm? i just push ctrl+alt+backspace).. but with a little more tinkering I should get it fixed... will update when I can figure it out~

Thanks for posting the solution, I've been looking for a solution to this too, and didn't know about this option. If the setting doesn't stick you can run 'nvidia-settings' with command line options from a script at starting X to set all of this. If you want I can get it and post it from my other computer.

I'm thinking of buying a nVidea GForce GT 430 and am in paranoid meltdown because of mixed messages about whether it or the driver are compatible with Linux.

So can I take it from this post that it is Linux compatible? Thanks any help.

The GT430 works with driver version 260.1921 onward. Nice card for a HTPC, for gaming in that price range I'd probably go for a GT240, as its about the same cost and does have a bit more power at lower resolutions.

If its not for gaming or HTPC use, a G210/GT220 would be just as good and chpeaer.

Ok, I get it now... I couldn't find the OverscanCompensation option within the "nvidia-settings --help"

but, I did see the '-d all' option which will let you see all the settable attributes. There you will see the OverscanCompensation value. I used

nvidia-settings -a [gpu:0]/OverscanCompensation[DFP-1]=100

to fix the edge cut-off problem. [DFP-1] maybe different depending on your setup (see the format for using '-a' and use the information given to you through '-d all'

Now, since I am using LXDE, I will create a startup script using a .Desktop file like this guy did in his blog:

http://linux.koolsolutions.com/2009/...-lxde-startup/

and is also described in

http://wiki.lxde.org/en/Autostart

Yeah, you can setup any of those values that get erased / not saved. I have to do this for fan speeds.
