The Asus PB278Q is a well equipped 27-inch monitor based on Plane to Line Switching (PLS) panel technology. You?ll pay more for this technology but receive awesome performance and a rich feature set in return.

  • +

    Great color quality. Lots of video ports. Ergonomic stand. Wide viewing angles.

  • -

    A bit pricey. No auto-pivot function. No USB ports.

The Asus PB278Q 27-inch HD monitor utilizes the relatively new PLS panel technology which results in excellent color quality and wide viewing angles. While it is quite pricy and has no automatic pivot function, it's still a decent monitor that provides a good quality image.

  • +

    Many video inputs, Wide viewing angles, Very good image quality

  • -

    Expensive, No automatic screen rotation

7 February 2013

Well-priced and powerful, the Asus PB278Q is the best entry point for those seeking an extreme-definition monitor at a not-so-extreme price.

  • +

    The Asus PB278Q offers a sharp extreme-definition screen, rich color, accurate presets, and useful ergonomic options at a good price.

  • -

    The monitor lacks USB inputs and its swivel mechanism is poorly implemented.

ASUS has a number of monitors specifically geared towards photo and video editing, but none with a resolution in excess of Full HD. The PB278Q has exactly that, with a resolution of 2560x1440 pixels on a 27-inch display.

I bought 2 of these: first one in Nov 2014, and second one in Aug 2015. I am now writing this in April 2016 and both monitors are having issues when using displayport input. The first monitor had no problem when it arrived.

  • +

    - Good image quality - Height and tilt adjustment is great and it supports vertical orientation - 3 year warranty

  • -

    - Displayport input issues, see below - Bright blue screen when turning off in HDMI mode - The edge below input ports extend out, making plugging and unplugging some cables difficult.

As a professional photographer, I was in search of a monitor that delivered color accuracy in sRGB. This monitor as certainly met my expectations. The built in speakers are great for listening to the news. I wouldn't "rock out" with them, but they serve in an excellent utilitarian role.

I bought this as a companion monitor for the PB278Q I purchased when the monitor originally debuted. The pair are amazing for my desktop setup.I loved it then and I love it more now. There have been a few updates to this model since it came out and all improve what was already a great display.

Bought this monitor in July of 2013 for over $550, which was a good price at the time. The monitor had a dead pixel or two on arrival but that doesn't bother me. It was otherwise well constructed and did the job. Since the beginning of 2015 I noticed that one of the physical buttons went dead.

10 May 2014

I do not find any problems with back light bleeding through as some have noticed. When using the monitor in day to day it really is not even noticeable. Now if I try specifically to get a screen full of one color or medium toned background then I may notice a small amount of variation in light...

Wanted to replace my 24" and 22" dual display with a 1440p 27" that could handle colour accuracy for my design work and provide the gaming performance I needed. I can happily say I didn't notice any ghosting with 1080p movies or input lag in Street Fighter IV.

  • +

    Beautiful, Vibrant and consistent colours, Low input lag for fighting games (26ms)

  • -

    No USB

14 September 2013

I spent several weeks researching WQHD panels and eventually settled on this one. I must say I was skeptical at first due to all the reviews stating that the panel often shipped with dead/stuck pixels.

  • +

    + Excellent viewing angles, excellent color, + Sharp text, even small print is very readable, + Excellent adjustable stable stand that works great and looks nice., + Stunning and feels very natural while playing any modern PC game, + Price is fantastic

  • -

    - Poor sound quality, - No USB Hub

I bought the display for gaming, going to be upgrading my GPU soon and I felt this was the best display to go with. The fact the display is so flexible is really a plus. I'm sure it could be used for more then just gaming. Price was not to bad

8 March 2014

I use this as an external monitor to my 2008 Macbook Pro. Using the displayport I can max out the resolution at 2560x1440. The colors are vibrant and streaming videos on it is great! There are a few inputs on this monitor, which is great as I'll probably hook up a PS4 to it.
