The Dell U2415 is an excellent tool for the photography professionals who work in the sRGB color space. Not only does it support the entire palette of sRGB colors, it also can display those colors with high accuracy since it’s average color error dE is measured at only 0.45. Even the highest-class media professionals will not be capable of perceiving such minor color error.
Pro Decent picture quality
The Dell U2415 is among the best monitors in the sub-$200 range since its native contrast ratio, peak brightness, gamma and color accuracy are on par with what the best monitors in this price range offer.
It displays beautiful images with rich and well-balanced blacks, accurate colors, and realistic intermediate tones that gives the picture some extra intensity. Dark scenes look deep as the monitor’s high-quality IPS panel offers a native contrast ratio of 1064:1, which combined with the monitor's overall color uniformity gives its blacks a good push towards high-intensity levels.

Finally, the monitor offers an integrated FPS counter.
Pro Excellent resolution
This monitor features the QHD resolution, which is arguably the best currently available resolution for gaming because it offers a good balance between the in-game field of view, aspect ratio, and the overall performance.
Compared to the regular FHD monitor, the QHD one offers a larger in-game field of view as it has merely more pixels to display the image. In some games, this will give you a massive advantage as the competitors who use the regular FHD panels will see less than you.
Just like the FHD monitors, the QHD ones also support the 16:9 aspect ratio which means that you will be able to run almost every existing computer game without having to deal with the annoying black bars on the sides of the screen.
Performance-wise, the QHD resolution doesn’t put that much pressure on your graphics card, compared to the UHD, which requires you to run more than twice the pixels of the QHD.
Pro Doesn’t exhaust your eyes
The ASUS PG279Q doesn’t take its toll on your eyes, as this flicker-free monitor has an integrated low blue light filter. Monitor flickering and the high-intensity blue light emitted by the backlight LEDs are among the leading causes of eye fatigue.

The monitor displays clear motion, free of artificial motion blur or ghosting effects because the ASUS PG279Q features some of the finest motion handling capabilities.
The ghosting effect is eliminated by the panel’s past full pixel response time of 4 ms, which allows each pixel of the ASUS PG279Q to change their color within only four milliseconds, which prevents rapidly moving objects from trails on the screen.
Moreover, the panel doesn’t have problems related to motion blur, as the Nvidia's ultra-low-motion-blur feature deals with the artificial motion blur effect efficiently.
Additionally, the overall motion looks smooth and fluid because of the monitor’s native refresh rate of 144 Hz, which ensures that the panel refreshes every seven milliseconds.
Motion handling is critical in competitive gaming, where the trails of ghosting or motion blur can affect your performance and not let you land that perfect long-range shot.
Pro Good picture quality
Regarding the picture quality, the ASUS PG279Q is one of the best gaming monitors money can buy, as it’s premium-quality AHVA panel offers native contrast ratio, peak brightness, gamma response and color accuracy, that only a handful of other gaming monitors can match.

Furthermore, the color representation is flawless, as the monitor’s average color error dE of 1.6 ensures that the color inaccuracies are so small that the human eye can’t spot them. Finally, the mid-tones look life-like as the monitor’s gamma is only 5% off from the ideal value.
Pro Responsive
Only a couple of gaming monitors can match the responsiveness of the ASUS PG279Q because of its amazingly low input lag of only 3.25 ms. Because of that, the monitor offers lag-free and connected gaming experience.
The input lag is an essential parameter for a gaming monitor because it tells how much time a monitor needs to process a frame generated by a computer. Overly long input lag makes you feel delayed in the fast-paced games.
Pro Exceptional gaming performance
The ASUS ROG SWIFT PG279Q is one of the best gaming monitors ever made. It has an exceptional balance of picture quality, motion handling, and responsiveness, that is spiced up by a generous amount of premium features.
Cons
Con Requires calibration
To get the most out of the monitor’s performance, you need to calibrate it. The procedure will take you 5-10 minutes as the monitor’s optimized ICC profile is available on the Internet.
Con Lacks speakers
Not a huge dealbreaker, but it's something to consider.
Con Not suitable for Adobe RGB content
This monitor is not the right tool for those who work with Adobe RGB as it supports only 70% of the Adobe RGB colors.
Con Doesn’t look good in a dark room
In a dark room, you can notice some minor backlight bleeding that occurs towards the lower part of the screen. Backlight bleeding appears when the panel can’t absorb the 100% of the monitor’s backlight and limits the monitor’s use in a dark environment.
However, this is a widespread issue for the IPS panels in this price range.
Con Expensive
At $799, quite the investment.
Con Not a lot of signal input
The monitor offers only one DisplayPort and a single HDMI input.
Con Needs calibration
To get the most of the monitor’s picture quality, you’ll need to adjust some of its settings. The procedure itself is straightforward as all the key parameters are available on the Internet.
Con Hard to unleash its potential
You’ll need a very beefy gaming rig to run the latest AAA titles at the monitor’s native QHD resolution and the 165 Hz refresh rate.
If you are planning to replace your old FHD monitor with a 144 Hz QHD one, it’s advised to research if your gaming rig is juicy enough to unleash the full potential of the monitor.
