VG280K - No signal

KUPO97

Hi

I recently bought a VG280K. I have its 3 ports connected to 3 different devices:

- DP: Connected to a MacBook Pro
- HDMI1: Connected to a PS4
- HDMI2: Connected to a Windows desktop computer

Every time I switch signal to the HDMI2 port (the Windows desktop computer), the monitor displays a 'no signal' message and then goes dark. It then comes on again, displays another 'no signal' message, and goes dark again. Finally, it comes back on again and now displays the Windows computer's output without any issue. This happens every single time.

Any ideas what could be causing it?

My old monitor (not an Acer) has been connected the same way and never had any issues.

Thank you!

Hi KUPO97,

Try to swap the cables and connect  the devices.

Microsoft has said they will be adding better support for waking slept monitors to likely the fall update (21H2). That should ease the issue. I believe what's happening is that they think the monitor has gone to sleep since the signal went away when you switched to a different device. When you switch back it takes them too long to realize it, and even longer to really recover.

Thanks both. I changed the cables around and it seems to work properly now.
