When comparing iiyama ProLite B2783QSU-B1 vs ASUS ROG Strix XG27VQ, the Slant community recommends ASUS ROG Strix XG27VQ for most people. In the question“What are the best FreeSync monitors?” ASUS ROG Strix XG27VQ is ranked 3rd while iiyama ProLite B2783QSU-B1 is ranked 8th. The most important reason people chose ASUS ROG Strix XG27VQ is:
The picture quality of the ASUS XG27VQ is one of the best among all gaming monitors in this price range. This is due to its VA panel that offers high native contrast ratio, excellent peak brightness, great gamma, and fair color accuracy. The XG27VQ does an excellent job of reproducing deep dark scenes, bright and vivid colors, and some eye-catching intermediate tones. The monitor can reproduce beautiful dark scenes thanks to its native contrast ratio of 3000:1 which allows it to display intense blacks. Colors look bright and vibrant thanks to the monitor's high peak brightness of 300 nits. Mid-tones look life-like because of the panel's nearly ideal average gamma of 2.25. Additionally, the monitor's color inaccuracies are almost invisible to the human eye as its average color error dE is only 2.6.

Pros
Pro Sharper than Full HD
The B2783QSU-B1 uses a sharp 1440p resolution which is a noticeable improvement over Full HD in terms of desktop size and in-game image quality. Compared to Full HD, there are 1.7 times more pixels displayed on the screen. This screen measures at 108 pixels per inch (ppi), while a Full HD resolution would result in a noticeably less sharp 82 ppi.
Pro Good brightness levels
Although Iiyama claims this panel provides a brightness of 350 cd (candela) per square meter, test results have shown that the actual result is even better than specified. With a a maximum brightness of 378 cd/m², this display outperforms the majority of its competition with similar displays only capable of reaching 300 cd/m². Especially for working environments with large amounts of natural light, a screen with a very high brightness such as the B2783QSU-B1 is very helpful.
Pro Great image quality
The image quality provided by the B2783QSU-B1 is excellent, as shown in multiple benchmarks. One of the ways this can be measured is by color temperature. The temperature of 6500 Kelvin is considered to be ideal for normal usage, as is corresponds to the color temperature of daylight. This display manages to achieve 6301 K - a 97% result. The same can be said of the gamma value which measures at 2,25 - the ideal result is 2,2. Contrast-wise, this monitor is also impressive with a result of 433:1 in the 'checkerboard test' - the most extreme situation for contrast testing. For comparison: the average results of the checkboard test is 300:1. In a more realistic contrast environment where images aren't either extremely black or extremely white, the monitor also holds up very well with 995:1.
Pro Fast response time ideal for fast-paced action
With a response time of just 1ms, the iiyama ProLite B2783QSU-B1 is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
Pro Low power consumption
Compared to other 27 inch displays with this resolution, the power consumption of the B2783QSU-B1 is fairly. At maximum brightness, the screen will require 45,7 watts of power, which is slightly below average. However, this display really shines in stand-by power consumption with only 0,4 watts of usage.
Pro Easily adjustable stand
You can easily adjust the height of the monitor, and you can also rotate it and switch between landscape and portrait mode.
Pro DVI and DisplayPort cable included
Both a DVI-D and a DisplayPort cable are included in the box, with the latter ensuring the best possible image quality and features.
Pro Superb picture quality
The picture quality of the ASUS XG27VQ is one of the best among all gaming monitors in this price range. This is due to its VA panel that offers high native contrast ratio, excellent peak brightness, great gamma, and fair color accuracy.
The XG27VQ does an excellent job of reproducing deep dark scenes, bright and vivid colors, and some eye-catching intermediate tones. The monitor can reproduce beautiful dark scenes thanks to its native contrast ratio of 3000:1 which allows it to display intense blacks. Colors look bright and vibrant thanks to the monitor's high peak brightness of 300 nits. Mid-tones look life-like because of the panel's nearly ideal average gamma of 2.25.
Additionally, the monitor's color inaccuracies are almost invisible to the human eye as its average color error dE is only 2.6.
Pro Supports FreeSync
FreeSync eliminates screen tearing and stutter, and reduces display lag because it allows the monitor to synchronize its refresh rate to the framerate of your Radeon GPU.
The ASUS XG27VQ supports the FreeSync in the 48-144 FPS range.
Pro Good motion handling
This monitor has multiple tools that enable it to display clear and blur-less motion even in the fastest FPS games, allowing this VA panel to compete against faster TN gaming monitors in this price range.
First, the artificial motion blur effect is virtually eliminated by the aid of ASUS's Extreme Low Motion Blur feature, which makes this LCD monitor behave more like CRT monitors.
Second, the monitor doesn't suffer from heavy ghosting as each pixel of the ASUS XG27VQ can change its color in 4ms.
Finally, the motion appears smooth and fluid because of the monitor's native refresh rate of 144 Hz, which enables it to display up to 144 frames each second.
Pro Well-built
The overall build quality of the ASUS XG27VQ suggests that this is a premium-class product. Each part feels rigid, as if the entire monitor was carved from a single piece of plastic.
Pro Has a desktop app
You can adjust all the monitor's settings using your keyboard and a mouse thanks to the ASUS's desktop application.
Pro Has a curved panel
The ASUS XG27VQ makes your overall gaming experience more immersive as its 1800R curved panel gives you the sensation of the screen surrounding you.
Additionally, the panel's curvature minimizes viewing angles on the sides of the monitor which noticeably improves the overall visual consistency of the panel.
Pro Has a crosshair
The ASUS XG27VQ has a crosshair feature which allows you to add a crosshair to any game. It could improve your performance in games like CS: GO and Rust, where you can no-scope your opponents.
Pro Exceptional gaming performance
The ASUS XG27VQ offers remarkable gaming performance as it combines superb overall picture quality with excellent motion handling capabilities, well-handled input lag, and high native refresh rate.
Pro Decent responsiveness
Even though no one has tested the monitor's input lag yet, it seems to be within the four-millisecond range according to the general user reviews and the input lag tests of other ASUS ROG monitors from 2016-2017. Such input lag makes the ASUS XG27VQ one of the most responsive monitors in its price range.
The input lag of a monitor corresponds to the time delay between a GPU producing a frame and the monitor processing it. The lower the input lag, the more responsive and connected your gaming experience will be.
Cons
Con Mediocre vertical viewing angles
As the ProLite B2783QSU-B1 uses a TN-panel which has the characteristic of having mediocre viewing angles compared to IPS-panels. Some color shifting occurs when viewing the monitor at vertical angles.
Con Maximum refresh speed limited to 70Hz
The iiyama ProLite B2783QSU-B1 is not as fast as some other gaming monitors, despite the fact that is supports AMD FreeSync. The minimum refresh rate is 48 Hz, with a maximum of 70 frames per second. Some of the more fast-paced games don't look as fluent on this iiyama as on other displays with a higher refresh rate.
Con Poor connectivity
The XG27VQ lacks USB connectivity, which might be a huge deal breaker in 2018.
Con LED ring is limited
You can't synchronize the RGB LED ring of the XG27VQ to other external RGB gadgets, like a graphics card, motherboard, or a cooler.
Con Overly aggressive design
Many users found the design of the ASUS XG27VQ to be overly aggressive and oversaturated with RGB elements.
