I recently bought a new monitor a ViesSonic VX2476-smhd https://pricespy.co....t.php?p=3764724 and connect it to my Asus GTX1070 Strix OC using the DisplayPort interface.

 

I set my PC to turn off the monitors after 5 minutes of inactivity. My primary screen, an AOC I2367FH https://pricespy.co....t.php?p=1491318 connected via the first HDMI will display a message saying 'No Input Detected' and will enter a low power standby after 5 minutes. However, the new monitor (ViewSonic) conencted via DisplayPort doesn't enter the same low power standby state but just turns off the picture (black screen with the backlight still visible). However when I swap the ViewSonic using DisplayPort to the second HDMI port on my Strix and leave it for 5 minutes, it displays the same message 'No Input Detected' too and enter a low power standby state.

 

Just wondering if this is normal that DIsplayPort doesn't cut off the signal to enable low power standby state and if it isn't is there anyway to rectify this. Cheers.

My three monitors working from HDMI, DisplayPort and DVI all work just fine, it's likely that the monitor just handles it oddly. Do you need it running over displayport rather than HDMI?

Only other thing I can think of is to try updating your graphics drivers. Not likely, but it is possible that that might be the issue.

I have the latest GeForce driver so I don't think it is that issue. I can leave the monitor to connect via HDMI for now but I'm planning on getting a G-Sync monitor in the next few months so if it's the monitor not handling the signal properly then so be it. However, if it's the DisplayPort that has some problems then it will be a bit troublesome to turn it off manually. Thanks for all the replies and help though.

Sounds a bit strange, and is definitely not normal. If it isn't the graphics drivers, the best explanation I can come up with is the monitor itself not behaving properly.

 

However, I just read of a variety of strange behaviour with putting DisplayPort monitors to sleep – but mostly it seems to be with Windows thinking the monitor is unplugged when it puts it to sleep and reacting appropriately, and you should know if that was what was happening...

 

What happens when you put the computer to sleep?

When the computer is put to sleep the same thing happens as with the display being turned off. The screen will be black but the backlight can still be seen. I swapped it to the second DisplayPort and the same thing still happens. Perhaps it is faulty or maybe a ViewSonic design I'm not sure.

In the manual it states.

 

"Power Management

This product will enter to Sleep/Off mode with black screen and reduce power consumption within 5 minutes of no signal input."

Yup but the message of 'No Signal Detected' didn't show up at all after the other monitor went to sleep. So it might be the graphics driver acting up or even Windows.

Interesting. I suspect that means the monitor is behaving normally. Try waiting 5 minutes after the monitor goes black, and seeing if the backlight goes off after that.

Nope I left the PC on throughout the night and when I woke up the monitor is black with the backlight still remaining on.

Weird, but I'm still guessing that it is the monitor responsible.

Hopefully it is as you say it's the monitor's problem and so when I get a new monitor it will be working just fine.
