The steps I take is as follows...

1- Insertion / Video / online Video / and I paste the youtube link

2- The video then appear in my power point (but is at 480)

3- I wish that have it at 1080p by default.

Is that possible?

It is possible to manualy set it at 1080 if I click on the bottom of the vid and change it. But I wish it to be at 1080p by default

Thanks
