The BenQ EX2780Q is an impressive gaming monitor that delivers a smooth gaming experience thanks to its high refresh rate, low response time, and FreeSync support. It has an IPS panel with exceptionally low input lag, though its contrast ratio is rather mediocre, making it less ideal for dark rooms. It's also a great monitor for media consumption, as it has built-in speakers and comes with a remote control, so you can just sit back and enjoy a movie or a show. The monitor's size and resolution provide ample space for multitasking, and its wide viewing angles are great for sharing content or for co-op gaming.

Our Verdict

7.7 Mixed Usage

The BenQ EX2780Q is a good monitor for most uses. Its 1440p resolution delivers a detailed picture, and it has exceptionally low response time and input lag to provide a responsive gaming and desktop experience. Unfortunately, its bad ergonomics make it difficult to adjust to your optimal viewing position, and dark room viewing isn't ideal due to its mediocre contrast ratio.

Pros
  • High refresh rate.
  • FreeSync support.
  • Great viewing angles.
Cons
  • Bad ergonomics.
  • Mediocre black uniformity.
7.6 Office

The BenQ EX2780Q is a good office monitor. Its 27 inch screen lets you multitask comfortably, and text remains sharp and legible. It has an IPS panel that provides great viewing angles so you can share your work easily, but the monitor's lack of adjustability is disappointing for those who need to work in portrait mode. The monitor has good reflection handling and it can get bright enough to overcome glare in a well-lit room.

8.0 Gaming

The BenQ EX2780Q is an impressive monitor for gaming. It has nearly everything that gamers ask for: low response time, low input lag, high refresh rate, and support for FreeSync. Its size and resolution provide great immersion in RPGs or atmospheric games, but sadly, it's not well-suited for dark room gaming, as it has a low contrast ratio and mediocre black uniformity.

7.6 Multimedia

The BenQ EX2780Q is good for media consumption. It has a great 1440p resolution that delivers a detailed image, and its 27 inch screen doesn't feel cramped. Viewing angles are good if you want to share content, and it has excellent gray uniformity with no visible dirty screen effect. However, its mediocre contrast ratio and black uniformity make it less suitable for viewing in a dark room.

7.6 Media Creation

The BenQ EX2780Q is a good monitor for media creation. It has a good size and resolution to let you work comfortably, and its viewing angles allow you to share your work easily. However, it has bad ergonomics, and the monitor can't display dark colors due to its mediocre contrast ratio.

6.9 HDR Gaming

The BenQ EX2780Q is decent for HDR gaming. Although it can get bright enough to provide a decent HDR gaming experience, it's limited by the monitor's mediocre contrast ratio. Its middling black uniformity can be distracting in dark scenes, and it doesn't have a local dimming feature. On the upside, it has a high refresh rate, low response time, and low input lag.

The BenQ EX2780Q has a fairly simple design that fits into any office setting. It has thin borders and the bottom part of the screen houses the internal speakers. The stand doesn't take up too much space, and you can use the rectangular space created by the stand to put other things.

The BenQ EX2780Q has an outstanding response time, resulting in a clear picture with very little blur behind fast-moving objects.

Like most monitors, the overdrive level can be adjusted. On this monitor, we recommend the 'Premium' setting, as it provides the best performance. However, there's a little bit of overshoot, which can cause inverse ghosting.

Response time is good when playing at 60Hz. It's slightly slower than when playing at max refresh rate, though it shouldn't be noticeable for most people. We recommend the 'High' setting, as the 'Premium' setting caused a significant amount of overshoot, resulting in the appearance of artifacts.
