Out of context, buckeroo. "W10 is excellent with Extended Desktop" so long as you don't run incompatible cards together.
How I have been able to cope with W10.... 1. Initially drove me NUTS, like everybody 2. Biggest problem... "create system restore point" kept failing... had to reinstall W10 perhaps 10 times before I decided to just disable it. So, I do "other" for backups 3. Uninstalled Cortana, One Drive, and Edge with Revo Uninstaller 4. Turned off EVERYTHING with O&O App Buster... When I tried to later run some function like music, photo, PDF reading etc... I'd get a message "no app to run this". So I'd go back into App Buster and reinable that function. I ended up with about 6 things enabled while another perhaps 25 remain disabled. 5. Use a little app called "W10 Manual Update" where I can periodically run and see what I want to update and what to skip... like "feature updates", you know. To make this work to my liking, 18 months ago I went into Windows Update and selected that updates can't be offered until 30 days seasoned... and "feature updates" (new versions) can't be offered until 1 year seasoned. Haven't opened Windows Update since. Now W10 and I get along OK... about the same as I did with W7... FWIW
I use win7pro on a pc I built 10 years ago and never use sleep mode. Asus mobo with 5 monitors. The pc has been on continuously for a decade hassle free. I reboot it weekly to clear memory. I never turn it off, the power cycling is bad for components. To avoid reshuffling etc, I just use external usb hdmi adapters to drive multiple monitors. Like these: search usb to hdmi adapters https://www.amazon.com/s?k=hdmi+usb+adapter&crid=3KD0EACWJMELV&sprefix=hdmi+usb+ada,aps,257&ref=nb_sb_ss_ts-doa-p_1_12 My wife, from Japan, calls me otaku. (computer nerd lol)
That is the way to go mister. As time goes by, PC makers and Microsoft are making worse and worse products. Windows 11 failed to fix the windows reshuffling problem. You are fortunate NOT to use the new DP Display Port. And you are smart not to use the power-saving SLEEP mode. The spacecraft going to Mars better don't use Microsoft 11 and DP port. It better uses Windows 7 and HDMI port and no SLEEP mode.
What's the physical layout of your connections? Do you run those through hub(s)? computer -1 internal monitor -2 -3 -4 -5 computer -1 monitor -2 -3 -hub -4 -5 Was there any configuration tweek that you had to do to get beyond 3 screens total? I used to use one of these Trittons to get 3 total screens from a laptop. Seems like that was the max possible. If an HDMI was hooked up along with the other two plus internal = 3, one of the vga externals would need to be nixed for the hdmi to go. but somewhere along the way when I hooked it up - nada. Wish I had a fix for that. (Tritton SEE2 Xtreme, USB to DVI or VGA External Video Card, 1920x1200 Max)
Right, I have several 4-6 port USB hubs.... afaik no limit to number of monitors..... need to buy 1 usb/hdmi adapter per monitor
Isn't using Windows 7 risky now? https://www.techadvisor.com/news/windows/windows-7-2021-dangerous-3807335/
A bunch of various utility options here you can try for backing up and restoring the locations / sizes of application windows across multiple monitors: https://superuser.com/questions/240362/save-window-locations-of-applications
OP, @Scataphagos is correct about this. When running 4 or more monitors, DisplayPort is the practical solution. And as others have noted, DP can be finicky about waking from either PC sleep or monitor sleep (with PC running). But a lot depends on your setup. I used to run multiple monitors using both discrete and onboard graphics, and I would have the issue of windows rearranging themselves. Sometimes even had BSOD's. I eventually moved on to two NVS 510 cards (onboard graphics turned off), and like magic, windows stay put when monitors wake from sleep (with PC running) and when PC wakes from sleep.
