Random tip on tweaking nvidia settings for a good picture
To use nvidia-settings from a remote workstation while watching live-tv/dvd/video:
Having problem tweaking your overscan/quality on tv-out?
An easy way is to use the remote feature of nvidia-settings:
Login to your mythtv-box with ssh.
First export the display enviroment on the mythtv-box:
Now (still on mythtv-box) Give your workstation X-rights:
This should give you an confirmation:
192.168.1.105 being added to access control list
Exit back to workstation, and execute the following:
Now you should get the graphical nvidia-settings, make your changes, and for safty restart X on the mythtv-box (its unsecure to share X like this, but the rules only apply until X is restarted)
Ofcourse this is my setup, so you have to use the ip:s of your mythtv-box, and workstation.
