Windows 10: 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

:)

 

1 of 2 new monitors not full screen


I have a gigabyte MB with on-board graphics, 1 vga and 1 DVI as outputs.

I have 2 new asus monitors with 1 vga input and 2 hdmi inputs.

The vga to vga connection to monitor 1 produces full screen on 1920x1080 (recommended)

Asus furnished a cable DVI to HDMI. This connection (monitor 2) leaves about 1/2 inch blank space on either side and about 1/4 inch top and bottom. 1920x1080 (recommended). 1280x1024 setting fills the screen, but display looks stretched.

Any suggestions appreciated.

 

Monitor flickering when connected to HDMI

I have the Gaming Laptop Acer predator 15, here are the specs:

Laptop - (Acer Predator 15)

i7-6700HQ Quad Core Processor 2.6GHz with Turbo Boost Technology up to 3.5GHz

15.6" Full HD (1920 x 1080)

NVIDIA GeForce GTX 1060 with 6 GB of dedicated GDDR5 VRAM

Monitor - (HP Monitor 22es)

1920 x 1080 - 21.5" IPS Display with max 60Hz refresh rate

HDMI and VGA Port

My issue is that when ever i connect my laptop to a monitor i bought recently the screen flickers every few seconds or more often when i start a video, for example if i open a new video on YouTube, as soon as the video
has loaded the screen 2 to 3 times before the video starts. The HDMI Cable i use is the one that was included with the monitor, i am running everything at it's native resolution and refresh rate. I have tried using a HDMI to VGA port, to connect via VGA and
the flickering is taken away but the quality is also reduced, i am a content creator so quality for me is important.

Any suggestions i should try?

 

Can't connect laptop to monitor via HDMI

Hi Parallax,

Thank you for your response.

We’d like to get more information regarding this issue.

1. Are you trying to connect for the first time?
2. If not, has it worked before?

It seems that the monitor/TV which you are trying to connect does not have setting to change input mode. Kindly refer to suggestion provided by 'Sandeep
Ghatuary' dated July 1st 2011 HDMI - connect desktop computer
to monitor.

Looking forward to your response.
