Win11
TLDR; on win11 when monitors power off after 30min (real SLEEP is disabled), the PC idles itself, and on wakeup there is ~ 30s of stutter / slow, and some windows position are moved around (as i watch , during wakeup they are re-positioned - mainly any that were mostly off screen/off-desktop) - im in IT / coding so have tried to debug this but am stumped. I really want it like it was on win10 where the monitors just power off and nothing else changes while they are powered off. (/end TLDR)

Prior to my move to win11 (when was on win10), when i would lock my pc (win+L , or let it idle for ~30min), the monitors would click off , at the direction of windows. (ie all auto-sleep settings on the monitors themselves are disabled). I have Sleep AND hibernation disabled, and my PC is on 24/7. (ie- ive only ever wanted the monitors to power off when idle/locked). My issue is: since my clean/fresh install of win11 (about 1.5 yrs ago)- ive always had an issue where when i "wake PC" (ie move mouse so that it powers back on the monitors) -

When this would happen, on win10, when i would "wake up pc" (move mouse/keyboard) the machine would come back on very quickly, with no changes to my desktop/windows, and it was clear that everything was still running in the background, *just as if the monitors were still on* , when/while the monitors were clicked off.
^I make this statement from seeing that:
1- Power usage (as read from my APC SMT-1500 UPS, barely changed with monitors off vs on on win10 - NB: the monitors are NOT powered via this UPS , only the PC's PSU)
2- Network bandwidth usage did not change (ie if i had a local IP-camera running, pulling 3mbit, that would continue when monitors off)


however, now on win11, the above 3x items are no longer true (as soon as WIN + Lbw drops a decent amount, PCs power usage goes down from ~230w to ~ 200w), but more importantly, it takes ~ 30sec for my system to be usable after I "wake it up" + and type in my local user password (not msft-online account). Also the machine stutters quite a bit those first 30s, until its done the "wake up" process. Most importantly sometimes my windows are moved around A SLIGHT BIT (i dont mean equivalent of pulling one of the monitors, but some windows that i had partially off the desktop will be moved back, fully onto the desktop, others might be reset a tad in size, minor window changes like these)

(despite the info below, this has always seemed to be the case once i moved to windows11 , and when i did move to 11, i started with new PC hardware + fresh/clean win11 install)

Im running latest Nvidia Studio Drivers: (this occured even when i was back in the 4xx version studio drivers).
EDIT: i should add, i have read and tried removing via Device-Manager, any/ all "Disabled" / greyed-out "Generic upnp Monitors" such that i only show the real 8x monitors that i physically have in use.

My own overview of my HW / SW:
Hardware:
8x monitors (5x @ 4k 60hz, 3x @ 2560p at 60hz)
2x GPUs - (1x nvidia RTX4000 , 1x nvidia p1000)
mb- Supermicro - H11SSL-NC Rev. v2.0 (currently is at the latest, non beta, supermicro BIOS version)
cpu- AMD EPYC 7262 (8core)
ram - 128gb ECC DDR4 SDRAM @ 3200mhz (4x 32gb sticks, all same, all from supermicros QVL for this model board -- exact is: 32gb HYNIX HMAA4GR7AJR8N)
drive- only 1x drive in system: Intel Optane p4800x 375gb (u.2 2.5" drive, plugs direct into 1 of MB's nvme sff ports)
only PCIe card (only HW addons really):
1x melenox connect-X2 10gb sfp card​
2x gpus (nvidia ctrl panel shows both gpus as: "BUS: PCI Express x16 Gen3" as it should be)​

Relevant SW: (this is not a recent issue, has been issue for over 1.5 yrs)
- win11 21H2 (22000.1042)
- NO antiVirus , win defender disabled (please keep discussion on my question, not if you agree with this or not, thanks)
- sleep / hibrationation fully disabled, in System -> Power: "When Plugged in, turn off my screen after" = 30 minutes
+ nvidia drivers = Studio Drivers (v517.40 - this also occured when i was back in the v 4xx version studio drivers )
+ in nvidia control panel, i have both gpus / profiles set to "Use Maximum Power" (i dont use/run Nvidia desktop)​
+ i do NOT have gpu Hardware-Accelerated GPU Scheduling enabled. (ie it is set to OFF) , i have tried it with ON for a week or so, same issue


Win Power Options Control panel -> Advanced Settings:
HDD Spin down = 0minutes​
USB Selective Suspend = disabled​
PCIe Link State Power Mgmt = off​
Display : Turn Off display after = 30 minutes​

Win Screen Saver Settings -> Use "Blank" , wait = 46min , On Resume, display logon screen.
(my concept is at 30min power off monitors, at 45min , "Lock PC", ie ask for user win password to log back in)​

NOTE- This issue has always been the case since day1 on this setup (about 1.5 years - 2 years ago), including through win11 updates, through GPU driver updates (ive always used nvidia Studio drivers, as i dont do any gaming).

thank you for your time-

Verify that all your settings are correct per this tutorial. Change Lock Screen Timeout to Turn Off Display After in Windows 11 Tutorial

If all your options are correct, see if the same stuttering occurs when you manually turn off display.
