Game "Monitor" No Signal (DisplayPort)
4.5
You use a DisplayPort cable, but the monitor says "No Signal" while HDMI works fine.
Symptoms
- Black screen
- No signal
- HDMI works but DP doesn't
Possible Causes
- Static buildup in monitor
- Bad DP cable
- Deep sleep mode
Step-by-Step Fix
1
The "Power Cycle" Fix
Unplug the monitor from the wall AND the PC. Wait 2 minutes. Plug back in.
2
Disable "DP Deep Sleep"
In the monitor's OSD menu, turn off power saving features for DisplayPort.
3
Try a VESA Certified Cable
Cheap DP cables often have a "Pin 20" issue that causes power problems.
When to See a Technician
DisplayPort is more sensitive to "handshake" errors than HDMI; a full power reset usually fixes it.
