White horizontal lines flickering on screen

Specs: Windows 8 x64
I'm completely stumped on this one.

I opened my laptop (Samsung ATIV Smart PC Pro) one day at uni, and for no reason to my knowledge, there were white horizontal lines flickering all over the screen.

I've tried various diagnostics on it, and have found:
- The screen looks fine from another monitor
- When I boot into safe mode, the flickering goes away
- Resetting the entire device doesn't help
- This problem sometimes goes away for a few seconds when I remove the GPU driver, but then immediately returns

I believe it's a driver problem, but I'm still struggling to pinpoint the exact way to fix the issue. Any suggestions?

Thanks in advance!

Possibly your graphics memory is f**ked - or possibly your GPU. Try turning off any hardware acceleration features the card has and see if that helps.

I can't seem to find any hardware acceleration features for my card in the Intel control panel...

The GPU is the Intel HD 4000.

Verify you are running the screen at its native resolution, which is 1920 x 1080.

What is the refresh rate setting?

Do you see these lines in both user modes of your convertible unit? I mean both in the open and the folded mode.

Yup, running in native resolution at 60Hz.

Could you please elaborate on folded mode? Not sure how I'd check for the lines if the laptop is folded.

I've also tried updating drivers, but to no avail.

Your laptop can open conventionally or fold back on itself like a tablet. Do you see the same lines in both modes?

Yes, I get this problem regardless of how I position the screen relative to the keyboard.

Is the unit under warranty? If so, make a warranty claim.

I reckon I will... Only about a month old
