To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
They are definitely very good ones same as described on the website but connecting both of them to my laptop was a pain. I have a Laititude 7400 and from the website and the catalogue in the box i thought they're daisy chained via HDMI but checking them i realized they are daisy chained via Display port cables. The stupid firmware does not allow you to adjust anything unless the monitor is connected to a laptop via HDMI or DP but i could not adjust anything and it does not automatically detect input, you have to manually select that from the second button from the left which is the only one that works when it is powered on and connected to the laptop/desktop but showing nothing. I find the firmware extremely stupid and i cannot dim the display (colour contrast and brightness option is dimmed for me), only reduce the blue light is avaiiable from the options menu) I failed to daisy chain it via display port bec my docking station has a mini display input and connecting it to the daisy chained monitor did not work (maybe my bad) but i do not have any other DP ports on my laptop or docking
