Main trade-off
USB-C power delivery is only enough for small devices rather than a laptop.


A specialist 400Hz TN monitor faces a sharper all-round 180Hz IPS screen.
The practical choice turns on resolution and refresh, then on the constraints in your own setup.
Before you choose
For a desk split between gaming and two side-by-side document windows, XG27ACS offers a wider native grid for each window. XL2566X’s high-refresh Full HD focus may still be the deliberate choice when competition dominates the purchase. Decide how much zooming and horizontal scrolling the working layout can tolerate before selecting the gaming specialization. Neither refresh figure promises the frame rate a particular computer will deliver.
An even split before interface borders is 960 pixels per window on 1920-wide Full HD and 1280 on 2560-wide QHD. Application scaling changes usable logical space.
The ASUS can accept a compatible laptop’s USB-C video signal, but its 7.5W power rating is not a replacement for a normal 65W laptop supply. Plan separate charging if that is the computer’s requirement. Choose ASUS for connection convenience when this two-cable arrangement is acceptable. Choose the BenQ around a verified competitive PC connection, without expecting either gaming refresh specification to power the source computer.
The XG27ACS specification separates DisplayPort Alt Mode from 7.5W power delivery. A working video connection does not prove that the laptop’s charging requirement is met.
