The issue is happening mostly while I watch video and it never disappear until I shutdown machine for an hour. I did reset NVRAM or PRAM but nothing works.
If I continue my work with horizontal lines after a while complete screen will be covered with lines and screen will be very laggy. Force to shutting down the machine.
Attached screen shot for reference.
MacBook Pro (13-inch, Late 2016, 4 TBT3), macOS High Sierra (10.13.6)
It's not graphics problem because screen shot looks good. Please see the attachment.
My laptop is out of warranty and it is 15 months old laptop. Is there any option apple can replace the display? because there is no physical damage. I hope there will be service support for display from apple even though the product is out of warranty.
I would like to know how many years apple gives guaranty for display.
Let's check if it's a graphics problem vs the display problem by taking a screenshot.

if you can see the line in screenshot, that indicates a graphic issue.
If there is no line in the screenshot, then is a display issue.
What do you see when you take the screenshot? Is the line there or not?
Post it here So we can see.
Also I wonder if your Mac is too hot. Here is some information about operating temperatures for your Mac which can be helpful to you.

I would try resetting PRAM a few more times. I've seen talk of it not always helping the first time.
After that, if it still is not good,
I'd suggest you bring it in to the Genius Bar at Apple and have them take a look.
Ok it’s the display.
this can help.
read the part about if you have a start up chime or not, then reset your NVRAM or PRAM accordingly.
you already did PRAM reset + doesn’t help, please do this:
