Did you disable Inject/Nvidia?

I tried to disable Inject/Nvidia and it is worser with flickering.... and still can not use DP port. Please help, also it report graphic card is 0M.

Your VRAM will only report "0 MB" if Inject/Nvidia is falsely enabled (and it definitely has to be disabled on your GPU).

Thank you so much Florian... so please help me to solve this problem. Everything working fine but look like I couldn't enable my Ndivia Quartro K5000... Please help !!!

Also how can I enable DP port...?? I remember DP port working with El capital OS.

Did you disable Inject/Nvidia now (-> VRAM should be reported correctly)?

This should be the only thing necessary to enable the DP port.

When I disable Inject/Nvidia -----> VRAM still reportt 0M.. and when I disable the screen couldn't useable because of flickering so much ... Anyway can I work around for this problem??
Thank you so much for your help in advance !!!

I think you're editing the wrong file or something like that. Disabling injection should definitely fix the 0MB VRAM bug. Make sure you're editing your active config.plist file (usually on ESP of your boot drive).

Thank you so much Fiorian;

Could you please show me how to fix it in config.plist file. I don't know how.

Thank you so much
