Viewing Angles

The CQ27G2 is definitely not a shareable screen. At 45° to the sides, there is a distinct red tint and a 50% reduction in brightness. Detail remains visible but picture quality suffers. From the top, we can see a similar effect with washed out detail. Stick to on-center viewing and all will be well.

Our CQ27G2 sample had reasonable screen uniformity when observed in a dark room. A slight hotspot in the upper left spoils the score a bit but we didn’t see any bleed or glow around the edges. Measurements taken of brighter field patterns showed a lower percentage of deviation from the center zone.

Pixel Response & Input Lag

Please click here to read up on our pixel response and input lag testing procedures.

It’s interesting to note that the CQ27G2 has the lowest refresh rate here but is not the slowest monitor. 165 Hz doesn’t guarantee a quicker response or less input lag. No one will be able to discern the difference between 6 and 7 ms. Skilled players will benefit from a 21 or 22 ms lag but 25 or 26 ms is plenty fast for nearly everyone.

    "FreeSync & G-Sync"

    "G-SYNC" and "G-SYNC Compatible" are two different things, this monitor does not have G-SYNC.
