Windows 10: Second monitor has trouble turning on when I start PC

I have 2 of the same monitors. Both are Samsung same model.
Both are connected with HDMI cables to my graphic card NVIDIA GeForce RTX 2060.

When I turn on the PC the main monitor turn on normal, but the second one is grey and all it says is HDMI port 2 both are connected to that port then it goes black and my main monitor turns grey for a second then turns back on and second one goes back to grey. It happens again and again. Second monitor is trying to turn on and somehow my main turns off like they are trying to be synced together.

Sometimes second one wont turn on at all and just stays off and it switches to one monitor style.
If I unplug the HDMI cable from the graphic card or the monitor itselfs and plug it back in it turns on normal and everything works fine.


They are brand new and when they work, they work. I have no other problems with them besides the second one not turning on with the PC like the main one.


I have tried reinstallling drives, playing with settings, googling but I havent find a solution.


I had dual monitors before but one was connected with HDMI and other one with HDMI to VGA/DVI cable and I had no problems then.

They are both on same resolution and 144hz.

second monitor

Hi Pauline,

Some of the advantages of having multiple screens (dual monitor) are it increases your productivity or it allows you to do multitasking. When awaking your PC after putting it to sleep, it will be directed at the sign in page. Normally,
the second monitor will just reflect black screen and the main monitor will reflect the sign in page. After signing in, your second monitor will automatically open if it is turned on.

If the second monitor doesn’t turn on, we recommend that you run the Power troubleshooter by following these steps:

• Click the Start button, then type Control Panel and then press
  Enter.
• Change the View by option on the top-right to Large icons.
• Click on Troubleshooting, and click on the View all option on the left pane.
• Run the Power troubleshooter.

If the issue persists, kindly refer to the resolution provided by

Let us know how it goes.
