I just find it easiest to just click the power button on my monitor before moving my mouse to wake up the computer. Update (7/7/29): This problem still exists. Yesterday, I found a new drive update for my AMD video card, so hopefully this will fix the solution after all. While the monitor is still on, I would wake the computer again, and the resolution would fix itself.
After waking the computer and when the resolution was wrong, I would put the computer back to sleep. Update (6/19/19): Since writing this post, I found an easier solution.
Let phone stay idle for few minutes, so it goes to sleep state. I’m not sure why this is happening, but my guess is that waking from sleep, Windows 10 isn’t getting the correct resolution from my monitor fast enough on some occasions. Change the display settings on your device by following the steps below: Touch Image. All the sudden, my monitor auto adjusted and I was able to select the 1920x1080 recommended resolution. I just unplugged my monitor and then plugged it back in. I researched online and tried many things such are uninstalling my video adapter’s driver and reinstalling the driver, but to no avail.
