Windows 10: External monitor keeps loosing signal when video is played

I really hope someone can tell me how to fix this. I have an HP laptop running Windows 10 and an Acer KG271 monitor. I started out using the Acer as the monitor with the laptop closed. This works fine, but if I go on a website like Netflix or AT&T TV Now, any video site except YouTube, the monitor stops receiving a signal and starts scanning all the inputs. I have to unplug the HDMI cable and plug it back in and it works until I make ANY change. Then it shuts down again. It's not just this laptop either, it's any laptop. I've also tried extending the display so both are on and duplicating the display. It happens the same way. Can anyone tell me how to fix this?

Monitor looses signal along with keyboard and mouse

hi, i have Microsoft Windows 10 installed on HP Micro Tower. Intel 2 core duo processor, Nvidia GT220 and Ram is 4gb.

on normal use the pc works around fine, but when i open a couple of extra tabs or use apps, the monitor tends to go blank (looses signal), along with a noise from the speaker (stops after 3 seconds) and the keyboard-mouse (usb) tend to loose power along
with connectivity . The led on the cpu blinks. On force shutting down and restarting, pc tends to work fine. But on excessive use (extra tabs), or video play this tends to happen

 

INPUT SIGNAL OUT OF RANGE while playing Wizard 101

Hi,

Thank you for writing to Microsoft Community forum.

• Since when are you facing this issue?
  

This happens if the signal from the video adapter exceeds the scan range of the monitor. The video card is feeding the monitor a signal stream in excess of what the monitor can accommodate. The two main causes for this are that either the resolution
or the vertical frequency is set high.

You may try the troubleshooting steps listed in HP and Compaq Flat Panel Monitors - Flat Panel Monitor Displays Message about
No Signal, Signal out of Range, Sleep, or Power Save and check if it helps.

Monitor going to sleep with no signal?

Your monitor is not receiving a signal from your video card. Possible causes: loose connection on either end of video cable (don't ask how I know this), broken lead in video cable, dying video card.

Disconnect and re-connect the video cable on both sides. If that won't restore the signal, try a different video cable. If still no signal, try your monitor on another computer. That will tell you if it's the monitor or your video card.
