Facing TV Problems? Ask a TV Technician.
Hi there and welcome
You mean your playing content from your Laptop, onto the TV but it is not displaying the entire picture?
Please let me know.
On the laptop, right click on the desktop and choose Display Settings.
Then Advance Display Settings.
Increase the resolution on the second screen (so click it first) then see if this fills it in. Try a number of different resolutions and tell me if this fills in the picture please
