    I have stuttering on PC connected to TV, when monitor is also connected to PC at the same time, but it in standby.

    TV - LG SK9500 connected to 1080ti via some HDMI 2.0 rated cable (CC-HDMI4F-6)
    +
    PC Monitor - Philips 247elh connected to 1080ti via some HDMI 1.4(?) noname cable

    Stuttering occurs in games like BF5 and Forza Horizon 4 (didn't test anything else). FH4 benchmark shows ~80 skipped frames in one run and i have stuttering (at equal intervals) ingame. In BF5 i also have stuttering (at equal intervals). And sometimes randomly TV lost video/audio signal for 1-2 seconds.

    Here is a sample of that stutters (on TV):


    But then i turn off the PC monitor by button (not even by power plug) - stuttering is gone and all is smooth on the TV. What it can be, how do you think guys?

    What are your power settings in global and game profile in NVCP?

    Try to check refresh rate first (from TV and Nvidia Control Panel)
    Also, reduce your graphics resolution to the maximum TV resolution that it can support.
    ------------------------------
    Easy one: Disable TV standby mode!:cool:

    All in default, but i've also tried maximum performance - no luck

    Tried different resolutions and refreshrates - still the same

    Problem occurs then i play on TV and monitor in standby mode, but then i play on monitor and TV in standby mode - there is no issues

    "Standby mode" as in when the panel sleeps? Or, are you referring to being the secondary panel, and the desktop is extended? @Mbi2011

    Bad cable perhaps or try without the other monitor conected.

    Also are you running the display in PC mode using a PC resolution and not an "HDTV resolution" in NVCP? Sometimes you think you will be using the right one but depending on the game it will call the wrong display mode and the refresh rate in the edid can often be slightly different in Video Timings vs PC Timings.

    As Chastity said, the problem might be with extended displays.
    Use one display only.

    It goes in that mode then didn't get any input signal, i didn't use extended desktop

    I didn't use extend / duplicate display options. Only "Show only on 1 / 2" display option

    I am using the same resolution and refresh rate as on PC monitor - 1080p 60hz. No stuttering without PC monitor connected to video card

    Didn't find any strange activities

    Also then PC is off (TV and monitor connected to videocard), TV shows me every few seconds that PC input is active:

    And then i turn off the monitor by button - this message disappears.

    So it's probably not PC settings related

    Install Smartcontrol Software.

    Got to Setup in Menu.

    RESET
    -------------
    Whats your windows version?
    -------------
    Check this tool: Intelligent Standby List Cleaner

    • The application will monitor and clear the memory standby list when it is > 1000mb (1gb).
    • It should help users who have stutters in games when using windows 10 Creator update and higher version of windows.

    Does your TV have a PC mode you can enable so that your PC sees it as a monitor rather than HDTV? On Samsung TVs you would just rename the input to PC. This might make it play nicer with your GPU maybe.

    I also have that issue, the only fix that works for me is using this tool: MSI Utility v2
    Just run it as an administrator, tick the check box for your GPU then restart your PC.

    EDIT: You need to do this every time you update your GPU driver.

    The latest FreeSync capable Samsung TVs might be different but most TVs look exactly the same on the source side whether you put them to PC mode or not . That switch usually alters the behavior of the TV's internal processor but that's fully transparent on the other end of the HDMI link. And even if the EDID changes between TV/PC modes (as seen by the source device) the main differentiating factor is if the display is detected as legacy DVI, native HDMI or native DP and that won't change. Native HDMI devices will be treated as TVs (even if they are in fact more alike of monitors than televisions, like small sized and have no DVB tuners, etc).

    Unless your hard drive/SSD is causing the system to hitch, It seems to come down to possible refresh rate differences between the two monitors and when one display is turned on, there is no stutter.

    At least when using borderless/windowed display modes, both displays should be running at the same or half of the highest refresh rate available.
    This is how DWM works when extending desktops. It runs at the primary monitor's refresh rate and whatever the secondary is running at will have to synchronize to the primary display's refresh rate.

    Try the below with only your TV connected first, then do the same with only your monitor connected

    - When your TV is only connected, if the Nvidia control panel shows refresh rates of 23, 29, or 59hz in the list it is reporting NTSC timings and these are what should be used. 60hz is still sent as 59hz for compatibility with applications that expect 60hz.

    - The exception to the above is if when your monitor is only connected, if none of the above refresh rates are available then 60 hz should be selected for BOTH displays because the monitor dictated it has the higher refresh rate.
