So, i recently got this new LCD BenQ monitor. (Model name is in the title) I waited for it to heat up from the cold, and then i finally turned it on. I played a few games for about 20-30 minutes, and then, suddenly, this annoying blue line appeared. I haven't done any damage nor have i spilled anything on the monitor. What could be an easy fix to this problem? (All of the service centres are closed atm because of the coronavirus, so I won't be able to bring it to them for about 2 weeks..)
