One of our beloved but aged Lenovo G570 laptops has got a "funny screen".

Everything is readable but the colours are all over the place, and there are swirly sort of patterns which should not be there.

An external VGA connected monitor displays perfectly.

A local laptop repairer (who kindly donated the M2.5x8mm screws requested in a previous post) reckoned it was a driver issue.

Uninstalling and reinstalling the driver made no difference.

Replacing the missing 6 screws also made no difference.

But upon reflection, I can state that the display looks odd in BIOS during bootup as well.

So that would rule out drivers and point to hardware, yes or no?

After dinner I will take a photo, though photos of laptop screens look odd anyway.

I'd say definitely yes to being hardware if the BIOS is showing the same issue.

It could be something super simple like a loose cable but laptops would be tricky to troubleshoot in that sense since you probably don't have a spare compatible display to rig up and test it with.

OK, I have to retract an earlier statement.

It actually looks OK once you hit F2 and go into BIOS settings.

But the initial startup logo

and Windows desktop look odd.

What happens if you start in Safe Mode, or boot from some super super basic linux distro? I'm not 100% sure but I don't think this should be happening on the boot screen (where it shows Lenovo) if it were a driver issue, as that part of the boot process is still before the OS is even loaded.

Possibly because the BIOS screen has a very basic colour scheme the distortion issue isn't obvious there?

Safe mode is affected by the issue.

I dont have another OS to boot from.

So starting to look a lot like a hardware issue.

Daughters laptop had the same issue. Then it started to come up with IRQ(?) errors at boot! In our case, video hardware is dying.

coffeebaron: Can sometimes be bad memory modules.

Good point! (Though in my case that was one one of the things I tried... swapped with another laptop and it made no difference, and memory was fine in the other.)

Had weird colours as the flex thru the hinge was on its way out on an old laptop. Not worth fixing as it was 5 years old when it failed so it ended up stuck somewhere as a computer to RDP into to do things.
