A vertical ghost'ish black line (sometimes flickers ) appeared on my Acer Predator B271HU bmiprz 27"

Alesstorm

As the title says, I don't remember when this line started to appear but it's more prominent in clear colors, like blue sky or white cream colors and it flickers when I'm playing games like minecraft or rust, I used different cables, DPI and HDMI but still the line is there, at the moment I turn on the monitor you can clearly see the line, the line gets curved at the top going forward to the right. Can someone tell me what it is, should I apply the warranty, what I can do? help

Hi Alesstorm,

Monitor self test,

1. Power OFF the unit.
2. Unplug all the cables.
3. Press and hold the power button for 30 seconds.
4. Turn ON the unit and check.
