Asus is adding another "overclockable" monitor to its lineup, the latest entry being the ROG Swift PG278QE. Not to be confused with the ROG Swift PG279Q, which we consider to be one the best gaming monitors, the PG278QE trades an IPS panel for a TN display, and is (presumably) cheaper.

Like its IPS counterpart, the PG278QE is a 27-inch monitor with a 2560x1440 resolution and G-Sync support. It has a slightly faster response time at 1ms (versus 4ms), and offers the same 165Hz refresh rate when overclocked (it's likely 144Hz out of the box).
