When connecting 4k monitor (ACER B326HK) having problems with DPC Latency related to dxgkrnl.sys on 3840 x 2160 resolution.  The system freezes within a minute.  Change all available drivers, tried to connect with different HDMI cables without any results. The system running well only at 1920x1080 resolution. When I change the frequency at 3840 x 2160 x 30Hz Windows don`t crush, but it lags badly. When trying to connect a 4K TV (TCL C715), the picture does not come out at all. Upgraded to Windows 11 did not help. Has anyone tried to connect a 4K monitor or TV?

    Hello!!

    @Yagorka

    I understand that you are trying to connect 4K monitor to Acer All-in-One PC Aspire C27-962 and it does not work. 

    For your information, the maximum support resolution for your All-in-One machines is 1920 x 1080 (FHD). It is a 27" screen. 

    This is the reason, why it cannot show any display to a 4K monitor. 

    Hope the information helps!!
