Which model do you have?
Please kindly describe more of the issue.
I got this issue too. my VIVOBOOK S15 WIN10/I5/8G....
When I output my HDMI to LG TV it become out of border.
I update all my driver and try NVIDIA MX330 driver setting.
BUT all the signal processing by CPU so MX330 can't do any help
NVIDIA guy tells me I should go back to ASUS not NVIDIA......
Sorry I'm a bit confused.
In your third picture, your display is exported to the TV, right? so the issue is out of boarder?
for this issue you may enter Settings>System>Display to adjust the layout and scale
You may post a thread in Chinese in ZH section if needed.
Thx for your kindly reply
I'm not sure which option can solve this problem. The minimal scale is 100% and can't do any lower adjustment or setting to Full screen option.
Both the sale and resolution need to be adjusted,
I mean scale can't adjust under 100% I'd tried all resolution to compatible with, but it seems like won't work at all
May you provide the specific model name of your LG TV?
if you connect to other monitor, does this issue happen?
