Text on your screen appears as lines or characters.
It might be your screen, the connection, or a component of the computer. Consider using a different cable first. If that didn’t resolve the issue, try connecting the PC to another monitor. If lines appear again, the problem could lie with the PC itself.
Start by testing other ports on both the monitor and the PC. If the issue resolves, you likely have a faulty port. Mark it as such. Try using a different cable. If that works, the problem was with the cable—this is unusual but common. Insert another video source into the monitor. If this fixes it, your GPU may be failing. End with a note: this could also mean your monitor is malfunctioning, especially considering the image you're seeing.
Take it seriously, it’s that tiny issue. Even after an hour or two of gaming, you won’t notice it. My screen has a scratch right in the middle—it’s pretty obvious—but when I start playing, I don’t remember it. In short, just move on and invest your money elsewhere.
