Lenovo Y450 - Horizontal wavy lines?

2011-11-26, 19:23 PM

Sup guys,

I have a Lenovo Y450 and the screen has weird horizontal wavy lines going across. I can temporarily fix it by switching the video output to projector only and then switch back but it reappears on every boot. It has the Nvidia G110M GPU and it's running the 285.62 drivers. This issue does not appear on an external monitor, only the internal one. Any ideas?

to make sure it's hardware issue, can you check if the issue persists on linux ( try live cd mode - without installing the linux - )

also, try to re-install/update the drivers.

if it persists, i suggest you to remove/replace the ram sticks first.
if it doesn't work, possible hardware issue, contact lenovo support line.
