curved 1440p at the 27ish inch size is what most of my gamer friends are settling for. myself, ive got bad eyes, so im staying at 1080p and 37inch. after a day at work reading screens, coming home to an easy to read monitor is a blessing.

thanks for the answer, might help others. line noise is so incredibly rare these days. hope you threw away that surge strip and got something else.

business refurbs tend to be the best choice.

you can search for others.

focus on the ends, not the cables. a damaged jack may work better with a ticker cable end that the longer cable has, instead of the older cat 5 cables that may put less pressure on the connection.

sometimes the pins inside the jack can be weak and not popup after a cable is removed leaving an open connection… you can usually see this if you look.

if you notice the pins that arent rebounding all the way up, they will possibly make poor or no contact. sometimes you can confirm this by gently pushing down the connector to force it to get a better connection.

shoving down with something else might help for a moment to test.

i think people tend to forget that “malware” isnt a virus because its often done in a legal way. yes, shitty software that you agree to, can do horrible things to your machine when you allow it.

the uninstaller should remove it. but “ooops” happens, ie bullshit code that causes things to stick.

99% of the time freeware malware bytes install will clear it for you. if you still get weird behavior after you run malware byes, then a reset might be worth it.

if you are talking about the volume button on a keyboard, its usually tied into the keyboard drivers that you would want to get from the laptop maker or keyboard maker and install.
