I am writing so that someone else doesn't make the same mistake as me and "cries" over their money. When we say that it supports 2 external screens, we mean in EXTEND mode and not DUPLICATE.

This product supports only DUPLICATE mode for 2 external screens, except for presentations where DUPLICATE mode is appropriate elsewhere. It says it in the manual, but no one mentions it. It says that for EXTEND mode, we only have from Laptop to 1 external screen, and if you add a second one, it is in DUPLICATE mode in relation to the first external screen. Unfortunately, it only says it in the manual:

Laptop+HDMI+VGA = Mode A+B & B and in 1080P.

I will also write to the company and let you know.
