Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.

getting “no signal” on both monitor and pc

my monitor started disconnecting when i’d run a game on my pc, it would work again if i forced shutdown the pc

this happened twice, then stopped.

now a few weeks later when my pc boots it will turn on the monitor but i’ll get “no signal” every time.

- i’ve connected the pc to a tv monitor - still no signal

- i’ve connected the monitor to a ps4 - still no signal

- i’ve swapped the hdmi cord for a new one and tried it with both - still no signal

- i tried both HDMI and DP cord on monitor to pc - still no signal
