Windows 10: windows are resized and snap to the upper left corner after monitor sleep

when my PC wakes up from from the display turning off the app windows are resized and snap to the upper left corner of the display. I then have to resize them and move them back where I want them. I tried updating the driver but Windows says latest driver is installed.

Application windows resize to upper left corner of monitor

Computer is locally built 2016, Intel Core i5 Skylake processor (6th Gen) 3.2/3.6GH, 80GT/s, 6MB, etc.
Monitor is Dell UltraSharp 38 Curved Monitor - U3818DW

Last update 2019-02 Windows 10 Version 1809 for x64-based Systems (KB4465065) successfully installed 6/18/2019.

In the last week, many, if not most windows do not open in the size I expect them to open. About a week ago, perhaps after the last Window update, two almost identical computers in our home are behaving the same way. Device manager says monitor is Generic PnP Monitor. Intel HD Graphics Control Panel says Display is Digital Television Dell U3818DW with the correct resolution of 3840x1600. Actual monitor is identified above.

Open windows, applications such as Chrome, Firefox, Word, MS Outlook. May or may not open in a floating window size as I like. I resize as needed, but then I leave computer, monitor goes off after 15 minutes. Computer is set to never sleep. All windows are in upper left corner, about 7x7 in size when I come back. Many times if I compose an email or open an email and reply to it, the window opens in a much smaller size, upper left area.

I think I've become a novice again; I don't know what steps to take to troubleshoot.

Windows are resized and moved to upper-left corner of screen when monitor wakes up from sleep

This question was asked before but with a different type of monitor. I have an ASUS MG28U. I am running Windows 10 and all updates are current. The problem is that every time I wake my computer from sleep status, all of the open windows will have been
resized and moved to the upper, left-side corner. Is there a solution for this yet?

 

Windows are resized and moved to upper-left corner of screen when monitor wakes up from sleep

I have a Dell 24" 4k Monitor (3840x2160) connected to my NVIDIA GTX 970 via DisplayPort 1.2. Whenever the monitor enters sleep mode, upon wakeup, all my open windows have been resized (smaller) and placed in the upper-left corner of the screen. This only
happens when connected to the DisplayPort output. If I connect to DVI or HDMI, the problem goes away. The problem, however, is those other outputs only allow 4K at 30Hz refresh rate instead of 60Hz which is not an option for gaming.

This seems to be a common issue scouring the web.
