Windows 10: Laptop monitor doesn't turn on after disconnected to HDMI connection for mutiple display mode

My laptop is currently only functioning through an external monitor via an HDMI cord to my television screen. I don't think anything is wrong with my hardware or lights behind my screen, but I don't know how to fix it. I've gone through Intel graphic settings and Windows display settings and there isn't a place to fix this issue. The intel settings seems to only have my Samsung telelvision screen listed under the monitors. It's as if my computer uninstalled its own screen. Please help, because I can't use my laptop without a screen unless I am home and that defeats the purpose of having a portable computer.

Laptop display and monitor will not wake when HDMI cable plugged into laptop.

I have a laptop. Lenovo ideapad FLEX 4-1480 Signature Edition.

The laptop has a display, and the laptop is connected to a monitor via an HDMI cable.

Sleep mode is disabled.

Screen timeout is enabled.

I lock the computer. The laptop display and monitor both eventually deactivate.

I move the mouse and press keys to wake the monitor. Nothing happens on either the laptop display or the monitor.

If the HDMI cable is not plugged into the laptop, the laptop display will wake as intended. The problem happens only when the HDMI cable is plugged into the laptop.

I have to remove the HDMI cable from the laptop, wait a few seconds, reinsert it, then the laptop display and monitor will wake. Again, the laptop display will wake just fine when the HDMI cable is not plugged in.

 

Vga monitor connected to my laptop via a hmdi port

Hello Andrew,

The VGA connector is a video connection for sending analog video signals to the monitor or TV. Unless you are planning to connect to a special monitor, such as a plasma or LCD TV that has a DVI connector, connect your Primary monitor using
the VGA connector.

The HDMI connector is a digital connection type for transferring high-definition digital video signals AND audio signals. When used with a compatible monitor or television, HDMI has the capability of carrying true high-definition video and
audio as well HDCP protected content. If your computer has HDMI audio, it should be set as the default audio device in Windows audio properties (available from Windows Control Panel). The monitor or TV with HDMI must have speakers to hear audio.

We suggest you try the steps below and check if this works.

• Open the "display settings" in your computer and activate output to the screen. You can either mirror content of your computer or extend the display just like a dual monitor screen.
• Check the "External Inputs" of your monitor menu. You will need to change the default "Video 1" to a different selection which may be "HDMI 1" or "Video 2" depending on how you have made the connection.

Important: Make sure you connect the cable to the laptop before turning on as sometimes it may fail to recognize external display.

Let us know with the outcome.

 

Second monitor not working with HDMI

Hi,

I have a AOC monitor hp Pavillion laptop and while trying to connect to the monitor using a HDMI cord, nothing is displayed. Comes up with a No Signal info. I have tried multiple cords : HDMI - HDMI, HDMI - DVI , HDMI - VGA, nothing works. The monitor is
not detected. I have another laptop on Windows 7 and and if I try to connect directly with VGA - VGA, it works, but does not work with HDMI from the same laptop. Basically, it does not work with HDMI at all.

I have updated the latest graphics card, both nVidia and Intel, but no progress.

If I use the same laptop and connect to my hd tv using the same cord it works, but does not work with my monitor. The monitor model is AOC e2450swh. It has support for HDMI. Even if I try to use a HDMI to VGA cord, still it does not display anything.

Any suggestions would be really helpful.

Thanks
