Omen Z4D33AA 27''
Microsoft Windows 10 (64-bit)

I started off by using my Z4D33AA with HDMI because i didn't have a DP cable laying around and i was going on a lan party in Norway while i'm currently living in Belgium. I got a DP cable at the lan party because i was competing in a PUBG and CS:GO tournament where i wanted to use the hertz because i'd been gaming on a 60 hz Samsung monitor. I got home to belgium and bought a DP cable compatible with over 144hz at my local tech store and went home where to my surprise there was a blue vertical line which popped up on my screen whenever i booted and turned off my PC. I didn't think that much of it at the time because it was only during boot and shut off, but after about 4 days i noticed it also ocasionally popped up when i was on my pc and also noticed that it went away but came back if i adjusted the screen. Now most people would say "check the drivers" or "the displayport cable is the problem" but it isnt. The Z4D33AA has a DisplayPort mode and a HDMI mode, whenever i change it to HDMI it still pops up. But now, after 2 weeks of having the DisplayPort cable, today, its just been there. It doesn't just pop up anymore, it just is there, all the time! It isnt the graphics card or anything, it isnt my PC or any of that because then when i unplug the monitor from the graphics card or the MOBO, it's still there! Ive checked online everywhere and done everything in my power to fix it and all but it's not working. I would do the "tutorials" on YouTube where you open up the back of the screen and unplug stuff and all that but it's literally a almost 750$ monitor, hense,  the reason for me not doing those tutorials. Ive also tried to go on the troubleshooting page on HP, but that didn't work either. Thank you for your time and hope to get an answer!

If the line is there even when no computer is connected, my "guess" is that you probably jarred something loose when you transported it.

Usually its a ribbon cable connection inside. If you are out of warranty, you might have to resort to opening the case as those videos suggest and reseat any connectors and such. There is no software solution that I know of to fix it.

 

If you are still under warranty, you need to contact HP Support using this link...

Today it's not there when I boot up but it is there sometimes on screen after I reach the desktop screen.
