- Confirm the monitor is powered on and the power light is lit.
- Reseat the video cable (HDMI/DisplayPort/USB-C) at both ends.
- Try a different cable or port if available.
- For laptops, press the display-toggle key combination (often Fn + F8/F4).
If a second monitor also fails, the issue may be the computer — open a ticket under Hardware.
My computer is running slowly — how can I speed it up? Posted on June 3rd, 2026 by JohnnyCommon fixes for a sluggish computer:
- Restart — this clears memory and is the single most effective fix.
- Close programs and browser tabs you are not using.
- Make sure Windows/macOS updates have finished installing.
- Check available disk space; free up room if it is nearly full.
If it is still slow after a restart, open a ticket under Hardware and note when the slowdown began.
