Monitor Randomly Goes Black? Check Two Timeouts First

Windows keeps two screen-off timers. On this PC they are 60 minutes and 4 minutes, which is why it feels random.

Google draws the line clearly, and knowing which side you are on decides whether anything you try will help.

SOS means your carrier is unreachable but somebody else is. Apple says emergency calls still work.

Pairing is stored at both ends. Removing the device in Windows clears one side and leaves the headphones holding the other.

One screen here runs at 144 Hz and another at 60. A game on the slower one is capped whatever the hardware can do.

The DNS server your PC uses is normally the box in the corner, not your provider. That changes where you look first.

Slow after logging in, then normal, points at one screen. Apple keeps every self-starting app in a single list.

Apple publishes the list and most people have never seen it. Free disk space is the answer for the majority.

USB and network working while the screens stay black means the video path failed, not the dock. Those travel differently.

A long unfamiliar file name is normal on Windows. Three checks settle whether one is legitimate, and they take two minutes.
