Hi

I have problems when I try to record 4k with nvenc, if under the output resolution to 2k if I can record but not with 4k, can anyone help me?

Thank you

AFAIK you need at least a Maxwell GM20x based GPU for 4k NVENC.
Could you also please provide a log?

Do you mean exactly 3840x2160 or slightly higher width? NVENC is able to encode up to 4096x4096. Higher isn't possible up and including Pascal GPUs. It always was 4096x4096 according to https://developer.nvidia.com/nvidia-video-codec-sdk#NVENCFeatures
