Extending windows desktop/duplicate screen will cause stutter

[Geoff Leven]

To the point,

Since upgrading to W10 from W7, I've noticed a very noticeable and systematic stutter exactly every 1 second while gaming having W10 set up in either extended or duplicate mode.

My Primary PC monitor is as below, and my second is a kinda old now Samsung HDTV (still good enough for watching movies).

Occasionally I like to play simpler game on my Samsung such as INSIDE and the like, as its a relaxing game that I just wanna sit back and chill playing it. However this has not been an option since upgrading to W10 because of the damn annoying stutter.

Before you ask, yes I've tried most of the obvious testing such as: Only outputting to the TV having the PC monitor disabled, matching the res of my PC monitor to that of my TV (60hz) toggling which monitor is the primary and secondary, turning off G-sync and pretty much all combinations of these. All to no effect. Simply put from what I can gather, the only way I can play games without the stutter is have the Samsung TV turned off.

Has anyone else experienced this?

@SkyNetRising, sorry for the abruptness of my reply, I know better then to answer like so if I want to get any real help and feedback. I've updated my OP with more info. Also Yes the nVidia drivers are the latest now stutter still there.

Since your upgraded windows 10 is having this issue, you can try clean install of windows 10 and see if problem persists.
It's possible that some remains of upgraded windows 7 is causing this.

Edit: One more thing - there is setting in Nvidia control panel called Multi-display/mixed-GPU acceleration.
See if changing this setting helps anything in your situation.
