    Hi,

    can you please send all the logs. Whole ‘/usr/NX/var/log’ directory if possible. You can send it to forum@nomachine.com.

    You seem to have two 4K monitors, that give the total screen size reported in the logs:

        Info: Using screen size 7280×1080.

    Unfortunately NVENC (Nvidia’s encoder) supports up to 4K, as you can see here:

    https://developer.nvidia.com/nvidia-video-codec-sdk#NVENCFeatures

    However this Feature Request, when implemented, will address your case:

    For the records, you can see that the hardware encoder is used when there is a single monitor:

        Info: Using screen size 3840×1080.
        Info: Using Nvidia H.264 hardware encoder.
