Hi @jp_jp,

take a look at your TV picture settings and the control switch for HDMI that says ā€œFull HDMIā€!.

I hope it helps. Merry Christmas. :smiley:

Hi jp_jp,

For such a new GPU youā€™ll most likely need a more recent driver, easily accomplished using the official ā€˜Graphics Driversā€™ PPA

  • Terminal
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
  • Once above is completed: ā€˜Preferencesā€™ (or ā€˜Control Centreā€™) -> Additional Driversā€™

You should now see NVIDIA driver 375.26 (most recent version) available for install

  • Reboot

For reference, PPA link

Hi @wolfman,

In case helpful (if this is what you are referring too), TV/NVIDIA driver settings, options for HDMI full/limited indicates colour range, not resolution.

Hi @DaveB,

thanks, I didnā€™t know that, I thought that it dealt with the resolution!. :smiley:
