Pixhawk 2.4.8 with OLED

Im using Pixhawk 2.4.8 latest version.
in the Mission Planer parameters list I do not see the “RTF_DISPLAY_TYPE” , so I can not set this OLED to work.
pls help

Do you mean NTF_DISPLAY_TYPE ?

yes, sorry “NTF_DISPLAY_TYPE” . I cant find this parameter, I have all other parameters ,before and after. but this one is missing

Maybe you have the wrong version of firmware installed. If you have fmuv2 you want Pixhawk1. The messages screen in mission planner will show what’s installed after connecting.

Thanks.
Im very new to Pixhawk.
How i know if my unit is fmuv2 ?
I have Pixhawk 2.4.8

In the messages Tab of Mission Planner after connecting it will show what version is installed.

hi
once I upgraded the Pixhawk 2.4.8 to FMUV3, I see now the NTF_DISPLAY_TYPE parameter.
thank you !!
