I am having an issue with my new Odyssey G9 in that after the monitor goes to sleep, it doesn't wake back up. Windows thinks the monitor is there and shows it in the list of displays. Pressing Win + Shift + Ctrl + b does fliker the screens, but the monitor does not wake up.
It does not appear to be a windows issue because if Windows goes to sleep before the monitor does, then everything comes back. Only after the monitor times out and goes into power save does this problem surface.
The only way I have been able for it to show back up is disconnect the cable or turn the monitor off and then on again.
I already have the HDR turned off, but it still does the lockup. When I put the computer to sleep, it seems to come back, only when I let the computer screen shut down and then the monitor shuts down. Once that happens, it will not wake.
Some graphics card drivers or Windows builds require a setting to be changed to send a 'wake' command to an external monitor. Since your monitor does wake under some scenarios, but not others, I recommend checking with the PC manufacturer and/or Windows forums, as this is a high traffic question for all manufacturer and OS providers.
All you have to do is hold the power button in (for about 5 seconds) and it will power the monitor off. Then watch the blue light. When it flashes (about 30 seconds later), then tap (press, but do not hold) the power button to turn it back on.
This works for me whenever it gets into this stuck mode. With this, and sleeping my computer at night, I have been able to minimize the need for doing this routine and it wakes up fine. Still happens if I leave my computer too long without putting it to sleep, but I don't do that often.
Aside from that (hopefully a firmware issue), the monitor is fantastic. I am just waiting for Samsung to release a working firmware. I am using 1005.4 which has been the most stable that I have been able to find.
My G9 fails to wake up every single morning. If I use any of my other monitors (ASUS, Dell, Acer) via the same port on the same GPU than it wakes up fine without issue.
For me the scenario where it doesn't work is when my Odyssey G9 is in use.
