The issue of content overflowing the screen is called
overscan, a common problem when connecting a computer to a TV. The primary solution is to adjust the display settings directly on your Philips TV.
Solution 1: Adjust Philips TV Settings (Recommended)
The best and quickest solution is to use your Philips TV's remote control to change the picture settings.
Press the "Home" or "Menu" button on your Philips TV remote control.
Navigate to the Settings menu, often represented by a cogwheel icon.
Select Display and Sound or a similar option like Picture.
Find Screen or Picture format.
Change the aspect ratio setting to an option that prevents zooming. The ideal setting names to look for are:
Screen Fit
Just Scan
PC mode
Auto Fit
Original or 1:1 mode
These settings will force the TV to display the input at its native resolution without artificially zooming in (overscan).
Solution 2: Adjust Settings in Ubuntu
If you cannot find a suitable setting on your TV, you can adjust the display settings from your Ubuntu laptop, though this might slightly compromise picture quality compared to a pure "screen fit" mode on the TV itself.
For NVIDIA GPUs:
Install the NVIDIA drivers and the NVIDIA X Server Settings utility if you haven't already: sudo apt install nvidia-settings.
Open the NVIDIA Settings application.
Go to X Server Display Configuration.
Look for an "Underscan" slider and adjust it until the screen fits.
For other GPUs (Intel/AMD) using xrandr:
Open the Terminal in Ubuntu.
Identify the name of your TV output (e.g., HDMI-1) by running the command xrandr --verbose.
Use xrandr to manually set the overscan/underscan borders. You will need to experiment with the pixel values (e.g., 30 pixels) to get it right:
xrandr --output <output_name> --set "underscan on" --set "underscan vborder" 30 --set "underscan hborder" 30
(Replace <output_name> with your actual output, e.g., HDMI-1).
