TL;DR: If your external monitor isn’t detected in Stellenbosch, check cable/port compatibility, update GPU drivers, and test display settings. Digissential resolves both software and hardware issues quickly.

Why monitors fail to connect

Coworking and home offices in Stellenbosch often struggle with:

USB-C ports that only charge, not output video.
HDMI cables/adapters failing silently.
Outdated drivers after Windows/macOS updates.
Laptops throttling or overheating, causing GPU detection failures.

These problems often hit just before presentations or deadlines.

Quick triage checklist

Check the port — look for a DP/Thunderbolt symbol near the USB-C port. Charging-only ports won’t output video.
Test the cable/adapter — try another known-good HDMI or USB-C cable.
Restart devices — power down both monitor and laptop, then reconnect.
Detect display manually —
- Windows: Settings → System → Display → Detect.
- macOS: Apple Menu → System Settings → Displays → Detect Displays.
Update GPU drivers — outdated drivers cause most detection errors.

If none of these work, it’s likely hardware (port, GPU, or mainboard).

When to stop DIY

If your monitor works fine on another laptop.
If your USB-C port feels loose or damaged.
If GPU drivers are up to date but detection still fails.
If the laptop overheats or crashes with an external screen.

These point to deeper hardware faults — time for pro diagnostics.
