Both products are good. I would advise to take the one that best fits your screens. Look at the specifications (size, weight support, etc.)

and just to clarify, my current screen is a 24''.

First of all, thank you for your answer and I'm planning to take this screen LG 27GL850-B (27", 2560 x 1440 pixels)

I already have a current screen that will be my secondary screen it is curved so is that a problem for the monitor mount?

Thanks in advance
