Hi all,

Running W10 Pro. As from today I see a vertical thin green line on the
right side of my screen. Would it be the monitor or the video card? It's
in all applications I use, on the same place. As I have a blue desktop,
I can't see it. Only in applications I open.
Any idea?

Many thanks beforehand,
With regards,
Fokke Nauta

Try a different monitor. If the line is still present, then it could be
the video card or some other fault with the computer.

Boot a different operationg system - perhaps from a USB stick. If the
line is still present then it's not the software.

If this is your HP laptop (or another HP system), start the HP Support Assistant and 'Run hardware diagnostics' from there [1]. There's a
diagnostic for the video memory (assuming built-in GPU).

[1] 'Fixes & Diagnostics' in the upper-right pane -> 'Run hardware
diagnostics' -> 'HP PC Hardware Diagnostics Windows' starts - 'Computer
Tests'.

Most likely a bad hardware driver for the screen matrix.

A colored green line, with blue background on either side,
would be a hardware matrix driver. If the green line was at the very edge
of the view-able area, then it is less certain which kind
of fault it is.

If the fault is in the chemistry in the panel, then the
number of lines affected could increase in the next two or
three months. .

There is the matrix layout, and a preferred direction
for these flaws. It's not likely a horizontal line will
develop, after the first vertical one appears. Succeeding
failures will also be vertical.

The monitor warranty, may have stated how many flaws and
of what type must be present, before the warranty applies.

You would likely need the purchase receipt in hand, to make
a warranty claim.

Monitors are made with "A" and "B" panels. Cheap monitors
are built out of "B" panels, which is why if there are
five identical monitors on display at the store, they
would all have one or more dead pixels if even one of the
monitors is spotted with a bad pixel. It is a purchase
choice of the manufacturer, to decide whether the price is
so low, only "B" panels will be used. If the manufacturing
process is a good one, there might not be any "B" panels
available when the panels are screened, and they are
all "A" panels. The point of explaining this, is if
you get a cheap monitor at the store on a sale, and
it has a dead pixel, taking it back and exchanging
for another unit from the same batch, odds are good
it also has a bad pixel.

But the green line means rejection of the panel,
and a whole batch of monitors should not all have
green lines when they arrive. Monitors are tested
with a camera and a computer, for visual defects.
and the testing is at the panel factory first, so
the panels can be sorted. The manufacturer may also
re-run the same test, on their assembly line.

Also you can possibly connect another computer like a laptop to the
monitor and see if it still has the line.

Unplug the vid cable from the monitor and see if the line remains.
You may or may not have a few seconds before the monitor discovers that
the vid feed is gone and turns off, so be quick!
Then do the same at the comp vid port.

Can you turn the monitor on without the comp being on?
Usually that is possible... for a few seconds.
If no change then reseat the vid card... if a vid card exists.

No, it's not my HP laptop, but a self build pc.

Thanks, Paul. I learned someting again.

But as of today the problem doesn't exist anymore.
But I'll keep a look at it.

I don't even know if I'll have a cable for that.

Perhaps it was a problem with the monitor.
