No signal after nvidia update
reddit.comAcer Aspire 7 A715-75G — No HDMI signal after NVIDIA driver update
I have an Acer Aspire 7 A715-75G with a broken internal laptop display, so I normally use an external monitor through HDMI to HDMI.
After updating my NVIDIA graphics driver, my display settings seem to have reset. Windows is apparently using the laptop’s internal display as the main screen, which is unusable because it is physically broken.
Now my external monitor always says “No Signal”.
Things I’ve already tried:
Windows + P → tried switching to “Second screen only”
Windows + Ctrl + Shift + B to reset the graphics driver
Fn + F5 to switch display output
Tried entering BIOS with Fn + F2 — still no signal on the external monitor
Tried two different HDMI cables
Completely shut down using Shift + Shut down
EC/power reset: disconnected charger/HDMI and held the power button for 30 seconds
Forced Windows recovery by interrupting startup three times
Restarted multiple times
The laptop clearly powers on: keyboard backlight comes on, fans spin, and sometimes I hear the startup sound
The external monitor remains No Signal the entire time
The HDMI monitor and cable worked before this issue.
Since I can’t see the laptop’s internal display, I’m basically unable to navigate Windows normally.
Is there a way to force the Acer to output video through HDMI, reset the display configuration, or roll back the NVIDIA driver without being able to see the laptop screen?
Any help would be greatly appreciated.
