You didn’t mention a possible price difference, did you?
In general, if the HW (graphic card) can handle it, a higher resolution is never a bad idea.
Attempt to learn the specifics of the graphics HW and compare them.
However, on a 15.6-inch display, it’ll be difficult to notice much of a difference.
I’m guessing both laptops have an HDMI port?
Do you have a decently sized LCD TV with HDMI port (32 inch or better)?
Viewing full HD (1920*1080) on such a screen would make sense.
Assuming, of course, that your videos are of this caliber (which isn’t always the case)!
It’s even possible to use two monitors at the same time.
While surfing, emailing, or writing on TVF on the laptop, I’m watching a video/movie on the LCD TV in full HD.
I don’t believe that surfing the web requires full HD.
Full HD is primarily used for watching videos and playing games.
