Can I use the VGA port display when installing jetpack to TX2?

Can I use the VGA port display when installing jetpack to TX2? what will happen if I use VGA port display?

Nothing can be guaranteed for such case. It has chance to work. But I think most of them just give out blanked monitor.

so that maens if I use VGA port display may led my installtion failed?(installtion jetpack to TX2)

Actually, it has nothing to do with TX2 boot up. You would just get blanked display.
However, since user needs a monitor to configure user account after rel-32.1. You may not able to get into system. This problem would be resolved in next release.

Just a note: VGA lacks the ability to autoconfigure. On the current release you have to log in once to create a login account…the account does not pre-exist. You can attach an HDMI monitor and keyboard just long enough to add that account, and then remove it if you wish.
