Horizontal lines on HP laptop screen
A line pattern shows a missing or extra row instantly; the colour tiles below show whether it is on every colour.
Plain colours, full screen:
Horizontal lines on an HP laptop screen come from one of three places, and the test tells them apart.
Test it now
Full-screen white, then black, then the colours: a panel line is fixed and identical on all of them. Tilt the lid slowly from 45° to 120° — a cable line changes or disappears. Plug in an external monitor or TV: if the lines are there too, it is the graphics chip or driver. Take a screenshot: a line in the screenshot is never the screen.
What it is
Horizontal lines on an HP laptop screen come from one of three places, and the test tells them apart. Lines that change when you tilt the lid: the display cable through the hinge. Lines that are also on an external monitor or in a screenshot: the graphics chip or driver, not the screen. Lines that are fixed, identical on every colour, and only on the built-in screen: the panel. Horizontal lines and bands usually point to the row driver or the cable; a band that flickers is nearly always the cable. HP laptops (Pavilion, 15s, Victus) use a thin 30-pin eDP cable through the hinge that wears at the left hinge; lines and flicker that change with lid angle are that cable, not the panel.
Can it be fixed?
Cable: yes, a small repair (the cable is a ₹500–1,500 part in India, $20–40 in the US, plus labour). Graphics driver: yes, free — update, or roll back. Panel: no, replace the panel. Graphics chip hardware: usually a motherboard, and on a laptop that decides whether it is worth it.
What to do
- Screenshot and external monitor first: lines on both = graphics driver or chip.
- Lid tilt: changes = cable; a small repair.
- Fixed on every colour, only on the built-in screen: panel quote.
- In warranty and no drop or pressure: claim it — lines are a covered panel fault.

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
