i just want to edit edit tdr delay in Nsight monitor but there is no option of "ok " button to apply the changes in tdr delay.
how can i resolve this.

I think you are in the wrong forum, but I will help you if I can.

You are using some form of the Nsight IDE (Nsight VSE, Nsight Eclipse Edition, or Nsight Tegra VSE), and these are the forums for NSight Systems (the system profiling tool).

I realize you may already have checked, but you can find the documentation for tdr in Nsight VSE at https://docs.nvidia.com/gameworks/content/developertools/desktop/nsight/timeout_detection_recovery.htm

The forums for the three IDEs can be found at:

https://devtalk.nvidia.com/default/board/83/nsight-eclipse-edition/
https://devtalk.nvidia.com/default/board/82/nsight-tegra-visual-studio-edition/

Hope you get the answer you need.
