Scaling position to player resolution

I’m making tutorial and i want to point on one place


and for example i have pos x 218 and pos y -737 and it loog great in resolution 1920x1080 but when i will change resolution to 2960x1440

i have problem
i read some topics on forums but i still dont know how to scale this values to make it right

From the screenshots I cannot see any problems.
From the topic I would assume that you need to set your anchors right.
