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 Picture-in-picture mode easily displays two inputs at once
Because of the wide aspect ratio, LG offers a built-in picture-in-picture mode (referred to as Split Screen) to display two inputs at once.
Pro Looks great from every angle
The LG 29UM68 uses has great viewing angles, both vertically and horizontally. Color shifting (distortion of colors when viewed at a wide angle) doesn't occur.
Pro No noticeable backlight bleeding
The monitor doesn't allow any light of the backlight to get through, which results in no noticeable backlight bleeding: that means dark areas remain dark as intended.
Pro Good value for the money
The LG 29UM68 is relatively inexpensive compared to other 21:9 displays and is a great budget choice if you're specifically looking for an ultra-wide display.
Pro Aspect ratio is ideal for movies, offers greater field of view in games
The LG 29UM68 is a display with a rather unique 21:9 aspect ratio, which is ultra-wide. The difference with a regular 16:9 display is that there are added pixels on both sides, which increases workspace. It's also ideal to watch movies as most recent movies are filmed in a widescreen aspect ratio. Some games also offer support for 21:9 monitors and will allow you to have a greater field of view.
Pro Provides great image quality and color reproduction
The IPS-panel used in LG's monitor offers great image quality, especially compared to the more common TN-panels. Contrast is great with a 1000:1 ratio (better blacks), luminosity is excellent, images are vibrant and the color reproduction is great as well. These attributes are all due to the fact that an IPS panel was used.
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 Refresh rate limited to 75Hz, not great for fast-paced action
The maximum supported refresh rate of this monitor is 75 Hz or 75 frames per second which is a tad faster than non-Freesync monitors, but is not as good as 120 or 144 Hz displays. Especially fast-paced games benefit from a higher refresh rate, as it offers a more fluid gaming experience.
Con Slow response time
The response time for the screen is limited at 5 ms, which is significantly slower than some other monitors. This makes the LG 29UM68 less ideal for gaming situations that require quick input.
