If you got a legacy model example F270i PRO, and trying to match it with the PG270 PRO, you may face some issue getting it to align on the same level.
I would recommend if there was a compatibility guide for VESA mounting height view compatibility as in the monitor to be on the same level view of display.
Yes I would also admit it was my fault, but nonetheless still an awesome product with good build quality.
The monitors are really value for money, the monitors arms also help to save alot of space and still give me what i needed to work. If you’re looking for something good and value for price, prism+ is really the one you looking for. Delivery is really fast too! Got mine within 2 days
