Hello :D
Here is the problem:

I just got my brand new monitor Acer Predator XB253QGPBMIIPRZX today and I saw weird bright dots on both sides of the monitor frame (?) (I don't know how to call it, sorry) that are visible when it is bright in my room.
When I look at it closer I can see the "+" sign and I am not sure if it has to be there :/ I've never seen this on any monitor.
Is it normal or should I return my monitor to the shop? Does anyone have similar problem?
Sorry if I wrote something wrong but English is not my primary language.
Best regards and thanks for help :D
