Icons and desktop items going to other monitor on turn off
If you have a multiple or dual screen setup, when you turn off one of the monitors the icons and open pages are sent there.
Software
This can be because there are not enough EDID close messages and can be a result of virtual displays being created. There are software solutions: HP_Reverb_G2_V2#monitor_resolution_goes_low_when_turned_off These work best for VR goggles (cleaning up the registry and turning off the creation of virtual displays) The utilities that are supposed to save the desktop icon positions and automatically restore them didn't work for me. Fences allowed me to save and then manually restore the icon positions but that drove me nuts.

Hardware
There are hardware solutions HP_Reverb_G2_V2#hardware_solutions which work best for me on a TV / monitor. Remember that the splitter needs EDID passthrough though.

SoftMCCS After establishing effective communication, softMCCS reads each connected display's EDID and MCCS capabilities strings. Within seconds softMCCS presents categorized information, current status and supported controls for each connected display in an easily-recognizable, property sheet metaphor. Beyond it's ability to simultaneously report the status of over 150 VCP code locations in a tested display, softMCCS also provides full control over each supported command and allows individual datagrams to be sent over the DDC/CI channel while viewing raw traffic in an ongoing log window. The speed of the underlying engine even makes it possible for softMCCS to react, in real-time, to events such as hot-plugging, changes to a tested display's orientation (portrait or landscape), and to synchronize with the use of a tested display's conventional OSD.

DDC / CI control
DDC / CI allows you to change the monitor properties without fiddling with the monitor controls itself.
mControl mControl is a lightweight replacement for display configuration utilities offering most, if not all of the features without the bloat. if your monitor supports DDC/CI and new WHQL display drivers continue to be released for your graphics controller, mControl should work. softMCCS includes comprehensive diagnostic support that can even help pinpoint problems with mControl. softMCCS includes comprehensive diagnostic support that can even help pinpoint problems with mControl (EnTech Taiwan)
ClickMonitorDDC Click taskbar notification icons to adjust the real monitor-backlight-brightness/contrast or use mouse wheel over notification icons to increase/decrease corresponding value, much more comfortable and faster than manually messing around with monitor buttons, works with external monitors (DDC-protocol) and Laptop-LCD-Display. define hot keys or mouse wheel combinations for executing command-lines. change color-profiles, select monitor-inputs, reset monitor, power off/on monitor, dim monitor, set monitor-speaker-volume, set system-volume, rotate display and set saturation/vibrance. You can do this by user-interface or by command-arguments.
Resolutions
Custom Resolution UtilityCRU shows you how the monitor defines resolutions and other capabilities and gives you the power to change it. Add custom resolutions, remove unwanted resolutions, edit FreeSync ranges, and more. CRU creates software EDID overrides in the registry and does not modify the hardware.
