ASUS ROG Swift PG278Q 144Hz G-Sync Gaming Monitor Review (Page 3)

Test System Setup


We appreciate the support provided by Corsair and ASUS in building our test system. Without their support, our job would be much more difficult.

On-Screen Display

In the video below, we walk you through the various OSD menus.

The OSD makes use of three physical buttons (not including the power button) and a five-way joystick. The joystick makes navigation of the OSD a breeze, and the physical buttons are only used to exit, access the on-screen Crosshair and Timer function, and change the refresh rate.


Power Consumption

Power consumption is measured at the wall with a blank Word document open and the monitor on as bright as it can go.


The ASUS Swift PG278Q consumes a massive amount of power sitting with the blank document open at full brightness and 144Hz refresh rate. We measured a consumption of 56 watts at the wall.


We use a LX1010B light meter to measure brightness in Lux. The monitor is placed in the center of the screen on a blank Word document with the monitor at full brightness.


With the high power consumption, we did get a pretty decent max brightness. The PG278Q came in second place with a measured brightness of 480 lux. I doubt this will be enough to offset the massive power consumption.


We use this as a way to measure a monitor's efficiency. It is simply the monitor's brightness divided by its power draw.


As I feared, the PG278Q bombs the efficiency conversion, producing just 8.6 lux-per-watt. It's the first monitor we've seen in the single digits, so we're going to have to assume G-Sync is energy hungry, since we have other 144Hz monitors on there that did quite a bit better.
