My new Dell monitor shows a tansparent window about Selecting Language

I just got new Dell S2419H monitor and when I hooked it up via HDMI a small transparent window opened in the lower right hand corner of the screen and it just wont go away. It is titled "Dell 24 Monitor" and offers a list of languages for me to select. English has a check by it. I tried to snip a picture of it to post here but the snip just showed what was under the window.

The monitor works fine in all other respects but I really need to know how to clear the pesky thing.

Will someone give me some help here. I've not been able to find a answer on the various Dell sites.

Thank you.

Have you tried pressing the control buttons next to the power button?

Thank you.

I am embarrassed to have to admit that I had not even noticed them. That did the trick.

Duuuude. I spent way to effing long this morning googling and trying all kinds of stuff to make that stupid box go away. It never once occured to me to push the actual, physical buttons on the monitor. 🤦
