Your Windows screen keeps flickering
Screen flicker is caused by a graphics driver problem, a loose cable, or a monitor refresh rate set too low. The fastest fix is to check your refresh rate in Display settings — it should be at least 60 Hz. If that's not it, try unplugging your monitor cable and plugging it back in firmly.
Screen flicker happens because Windows and your monitor can't agree on the display speed, or the connection between them is unstable. A loose cable is the first thing to check because it's the easiest fix. If the cable is fine, the graphics driver probably needs updating.

Skip — I just want a technicianCommon mistakes to avoid
- Setting the refresh rate too high for the monitor to handle — stick to 60 Hz unless you know the monitor supports higher
- Plugging the monitor into a USB hub instead of directly into the computer — hubs don't provide stable video signals
- Using an HDMI cable when a DisplayPort or DVI cable is recommended — some cables are better for stable signals
Signs you need professional help
- You've tightened the cable and updated drivers, and flickering still won't stop — the monitor can need replacing
- Flickering only happens with certain cables — the monitor's input can be failing
- Flickering is so bad you can't work on the computer safely
