Windows 10: PC monitor goes blank when running any application in fullscreen mode

Hello. Any time I run an application in fullscreen mode my second display goes blank. The only workaround is to run in borderless windowed or windowed mode, which not all of the applications I use support. Is there any solution to this? I am running of an MSI GS66 Raider top spec and my main monitor is running off of a thunderbolt 4 dock. This issue appeared suddenly, it used to work fine before and now it suddenly broke all of my fullscreen applications.

Monitor goes into sleep mode during fullscreen applications

My monitor goes into sleep mode for 2-3 seconds every 5-6 seconds in full screen applications. However this only starts to happen after waking the computer after windows has turned off the display after 15 min as set in the power options. I have 2 monitors,
an AOC connected via displayport and a dell via DVI. The AOC is having the issue however the dell isn't affected at all when the problem occurs. They are both hooked up to an MSI GTX 970. I have updated the graphics driver twice since I got the screen, which
hasn't fixed the issue.

Does anyone have any ideas or suggestions on how to fix this?

 

monitor goes blank

hey, i have a samsung 22"ws and an 850xt. 1 gig of ram and an old xp3200. Every time I watch a movie in powerdvd or media player i can get some of the way through it and then the monitor goes blank and it acts like the cable is not even hooked up. After that I have to reset. Atitool temps are fine throughout on vid card and mobo temps are good as well. I was just wondering if anyone may have a suggestion at to what it may be. Thanks.

 

"Scroll Inactive Window" does not respect Fullscreen application in multi-monitor config

when "Scroll Inactive Window" (settings > devices > mouse/touchpad > Scroll Inactive Window when I hover over them) is active it performs inconstantly with fullscreen applications, and the way the mouse performs otherwise with an application in Fullscreen
display mode. the feature works fine otherwise, but this side effect makes it frustrating.

for productivity this feels functional, and fluid. this mostly impacts things like games, but it still does not feel intended, or consisted with what Fullscreen is supposed to entail, or what things are actually constrained.

expected: in fullscreen mode the mouse is supposed to be completely constrained to the given screen/monitor, and all interactions of the mouse are expected to only interact with the window the mouse is locked to. for the most part this is why borderless-fullscreen
(or fullscreen borderless windowed mode) was implemented to have a program appear like fullscreen, but allow the mouse to behave like windowed mode.

issue: when running a fullscreen application like a game with "Scroll Inactive Window..." active, and using the mouse in the program, if the mouse would logically leave the fullscreen application "Scroll Inactive Window" will function even though any other
button of the mouse will do nothing, and with the logical position of the mouse being invisible to the user. this occurs with most any fullscreen application, and impacts multi monitor configurations.

example: having a program running in fullscreen mode (most prevalent in games), with a youtube video (could be a text document/webpage), and have the mouse logically leave the fullscreen application (if left monitor is non-primary then run mouse to the left)
then use scroll wheel. this is inconstant as clicks and secondary buttons do not function.

can this feature either respect fullscreen display mode, or maybe have a sub toggle for "use Fullscreen mouse lock"
