Windows 10: Games no longer work on primary monitor

Hello

I am having an issue where it appears that the I cannot run ANY game on my primary monitor anymore natively.


If I run a game at 1920x1080 or lower resolution, it displays on my secondary monitor which natively runs at x1080. My primary is at 3840x2160. No matter how many times I select 'display 1' in whatever game or program I am using, it still uses the secondary monitor for some reason.

The only workarounds I have found are upping the display resolution or running the game in windowed mode (can't do fullscreen as it just defaults back to secondary monitor for no reason.)

Bonus issue: If I disable the display in Windows, or otherwise unplug it - any game I try to run afterwards doesn't work at all!

Is there any way to fix this issue so that I can get software to properly run on my primary monitor without changing the display resolution? This has really been bugging me and so far nothing has worked.


I am running Windows 10 Pro (64 bit) and have a NVIDIA 980 GTX.

Help?

:)

 

How do I make games open on the primary display?

I have 3 monitors on a nvidia GTX660Ti, with the latest drivers, on windows 10, upgraded from win7, on a PC that I have been gaming on for quite some time now. The hardware itself has been an excellent gaming rig up until the windows upgrade and/or the
nvidia driver upgrade, but now a number of my games will not start on the primary display, they start on the first display in the list, which is not marked as primary. Both the windows display settings and the nvidia control panel have my central monitor
identified as the primary display.

• Has anybody encountered this behavior?
• Is it likely to be windows 10 related or decided by the nvidia driver?
• Any suggestions on getting this to behave properly, like it used to, without requiring me to disable the other displays to get the primary to be used?

 

The taskbar locked to bottom of secondary monitor moves to the primary monitor whenever primary monitor is switched on.

See the title.

I have the taskbar locked at the bottom of the secondary monitor so the primary monitor is completely empty for watching movies, games TV etc.

Whenever I turn the primary monitor on, the taskbar immediately jumps from the bottom of the seconday monitor over to the bottom of the primary monitor. I then need to untick the 'Locked' option on the taskbar, drag it back to the secondary and tick 'Locked'
again.

The taskbar disrupts desktop icons on the primary and any application running on the primary monitor at the time and quite frustrating.

Primary monitor is an Asus PB328, connected via Display Port to the PC.

Secondary monitor is a Samsung 24 connected via DVI to the PC.

I expect the taskbar to remain where I place it when locked, regardless of monitors been switched on or off.

The sequence of turning on the primary and secondary monitors has no impact. As soon as the primary monitor (Asus on DP) is turned on, the locked taskbar moves to the primary display, regardless of whether the Samsung is on or not.

 

Monitor Primary monitor layout switches upon second monitor power off

Hi alts63,

One of the possible reasons why your primary monitor layout switches is that the rotation lock option is turned on. In order to turn that off and fix the issue, please follow these steps:

1. Press Windows key + A on your keyboard to open Action Center.
2. Click the Expand button.
3. Click the Rotation lock to turn it off.
