Looks like tic tac toe lines on my screen.
 

I don't know how it happened. I don't know how to get rid of it. Anyone have any ideas?:willy:

Laptop? Wiggle the screen and see if it changes. The hinge connection might be worn or corroded. I get green pixels crawling through my image unless I shake the screen a bit.

Desktop monitor.

Subscribed. I don't have any answers, but my older Samsung TV has vertical lines throughout the whole screen when I turn it on most of the time. They usually lessen and disappear within maybe 10 minutes or less, then I get the usual, crisp picture.

Only one monitor??? OMG.

That's for my oldest computer that I use. :leaving:

The monitor isn't but a couple years old.

Not ballah

Have you unplugged it and let it sit for a bit? Next up hook to different source see if its the monitor or card/computer go from there.

First thing I would guess is magnetic flux interference. Perhaps a pair of speakers, router, or some other electric gizmo is sitting too close to the screen or the cable leading to it.

@datawiz has monitors that look just like that. :D

Time for a new one. :yesnod:

Showed that pix to my wife, she has never seen that on the monitor.....BUT when she takes a pix of the monitor display, the pix has those lines in it.....




SO>>>>>>>>:dance::confused5:

My Asus monitors had an alignment grid that accidentally got turned on. https://www.asus.com/support/FAQ/1042616/

That was it. :hurray:

Congrats on the fix! :cert:

Thanks. I knew someone here would know.

This leads me to believe he needs to repair the flux capacitor.
