Blank Screen

Hi Virginia,

Conflicts with third-party software and outdated graphic drivers are common contributors to the black screen issue that you're having. To isolate the said issue, we'd like to ask a few questions:

• Are you getting any error messages before getting a blank screen?
• Are you experiencing this when using a particular app?
• Were there any changes made on your computer settings prior to this issue?

Meanwhile, we suggest that you refer to this
article which talks about the steps you can take to resolve blank screen errors.

We'll wait for your response and assist you accordingly.

 

Blank Screens x 2 if Ext Monitor connected via HDMI

Dell Inspiron 17, 5000 series, Windows 10, fully up to date re Updates etc. Recent purchase

Recently, 3 of us got together, as we do regularly, each bringing own laptop along. I also take a monitor so we can all see the same thing, ie a tutorial. This arrangement seems to work well and I don't have issues.

However, when another (friend's) laptop was connected to Ext Monitor via HDMI cable (to show something on his laptop for all 3 of us to see), clicked on 'Duplicate', (first time setting up with Monitor) his laptop screen went blank but the Ext Monitor wouldn't display his screen either, just black too.

The laptop screen came back on when the HDMI cable was unplugged!!! Clicking on different options re Ext Monitor had no effect.

As mentioned, we'd had no problem with my laptop screen displaying on the Ext Monitor, using same cable, plus another longer) cable.

We tried the relevant Fn Key, Settings-System-Display but couldn't see any settings to change. With the Ext Monitor not connected, there was no way to try clicking on 'Identity' or 'Detect' but, if connected, both screens are just 'black'. Surely, it must be down to a setting somewhere ... ??? *Wink

Apparently, same happens when this laptop is connected to TV although 'old' Dell laptop was fine when connected to TV.

Has anyone any suggestions, please? Any help/advice would be much appreciated

Many thanks
