Windows 10: No signal to external monitor. All drivers uninstalled and updated.

My external monitor has recently lost the signal from my laptop and I've tried every bit of advice out there to try to get it back, with no success. I have a Dell XPS 15 9550 laptop, and an old Dell S2409W external monitor. It was working fine via a DVI-D cable, but lost it's connectivity at some point when I was uninstalling / updating drivers for a Zebra LP2844 printer; as part of my troubleshooting the printer, I deleted a few drivers that were showing errors in Device Manager (stupidly without noting what I uninstalled). Once the dust cleared, the monitor no longer works.

Details of what I have tried:
Currently, there are no errors or conflicts displayed in Device Manager. It only shows a Generic PnP Monitor.

I have replaced the cable, no effect. I have tried an HDMI cable, but the monitor is locked on DVI-D input, and I cannot unlock the menu to select another input. I've tried unplugging the monitor and holding the power button down for 15+ seconds for a hard reboot. No effect.

I have uninstalled all monitor drivers, as well as NVidia, run both Dell and Intel driver updates. I have installed the specific Dell S2409 driver onto the Generic PnP driver. None of these has had any effect.

The monitor does power on, and the display works - it just shows "Entering Power Save Mode" when plugged into the laptop, then goes dark. I don't have another machine with a graphics port with which to test it unfortunately.

I've run sfc /scannow, I've run Windows Update.

I'm at the point where I'm considering a complete rebuild, but would love to avoid that if anyone has any further advice to try.

Thanks!

External monitor blanking often

Hi,

Please answer these questions to assist you better.

• What is the make and model of your computer and external monitor?
• Have you installed all pending Windows and driver updates?
• Do you get any error message?

I suggest you to install all pending Windows updates in your PC and also update Display drivers. Follow the steps below.

Step 1: I would suggest you to check and install any latest Windows Updates available.

• Go to Start and then Settings.
• Click on Update and Recovery.
• Check for updates under
  Windows Updates.
• Restart the system and check if the issue is resolved.

Step 2: Please refer to the following Wiki article created by

External monitor not working after synaptics device driver update. Can't uninstall driver

Upon starting my laptop a couple of days ago my external monitor stopped working. The laptop screen was fine but nothing displayed on the monitor. I swapped the monitor out for one on another PC and the new monitor had the same issue. The one that I thought
was faulty worked perfectly fine on the other PC.

After checking the update center the only change made to the system between monitor working and not was an update to the Synaptics Pointing Device driver.

Some googling lead me to some links that suggested an issue with mouse drivers and windows 10. I followed the instructions which were to disconnect external mouse from laptop and restart with it unplugged...astoundingly that worked...yesterday...today however
no monitor and external mouse trick not working either.

I have tried uninstalling the driver that was installed and disabling the touch pad. The first time I uninstalled the new driver it rolled back to an older version but this did not solve the issue. So I asked windows to completely uninstall the touchpad
driver. However, when I restarted the latest version of the driver was back again and every time I log in it says the device is working properly but a hardware restart is required to finish modifying the device.

After multiple restarts I cannot get the driver to uninstall or think that it is fully installed and Ok.

My preference would be to have the touchpad and monitor working but if I had to choose one I would like a fix to have the external monitor working.

Any assistance appreciated.

Cheers,

Sean

 

How do you uninstall chipset drivers?

I'm installing a new mobo so I need to uninstall the intel 865g drivers to make way for the P35 drivers.

Can't find any uninstall options in add/remove programs and intel chipset inst listed in driver cleaner.

Any suggestions? *Confused
