Pros
Pro Great viewing angles
As expected from an IPS panel, viewing angles are great. Horizontal adjustments don't change the colors much at all. When tilting in the vertical axis, the image can darken slightly.
Pro Lots of ports
With 5 USB 3.0 ports (one of which can act as a charger), 2 HDMI ports (with MHL), a DisplayPort and Mini DisplayPort, as well as a DisplayPort out port for daisy chaining multiple screens
Pro Fully adjustable
It has tilt, swivel, height adjust and can be pivoted 90 degrees in both directions.
Pro Great for multi-monitor setups
The thin plastic bezel (1mm) and small 6mm screen boarder makes this a great screen to put side by side with another to minimise the deadspace between dual monitor setups. Also, an extra DisplayPort out means daisy chaining is possible.
Pro Fantastic screen quality
Dell calibrates the U2715H's screen in the factory to very precise measurements, and each monitor will have their own unique calibration report.
Pro Fast response time, great for gaming
With a response time of just 1ms, the iiyama G-Master Gold Phoenix is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
Pro Provides excellent viewing angles for a TN panel
Although the Gold Phoenix monitor uses a TN panel, the viewing angles of this monitor are excellent, especially regarding brightness. The brightness under a horizontal viewing angle of 45° is superior compared to other displays with a reading of 56%. For comparison: similar TN-panels such as G-Master Red Eagle only score about 47% in this brightness test.
Pro All cables included
All connection cables are included with the monitor, including HDMI, DisplayPort, mini-DisplayPort to DisplayPort, USB and Audio. No need to purchase any other connectors.
Pro Extremely sharp
The G-Master Gold Phoenix GB2888UHSU-B1 uses a 4K-display with a resolution of 2160 x 3840 pixels, which is four times the amount of pixels of a Full HD display. This results in an extremely sharp image and overall great image quality. In terms of pixel density (measured in pixels per inch), the Gold Phoenix has 157 ppi, while a Full HD screen of the same size has a ppi of 78.
Cons
Con Buttons can be unresponsive
The captive buttons on the right side of the bottom bezel don't light up at all, and can be unresponsive when you first try to activate them.
Con Poor panel uniformity
While this will vary unit to unit, TFT Central found that the luminance uniformity on their unit was poor. The right side of the screen was up to 30% brighter than the left corners of the screen. It wasn't obvious at first glance, however for color-accurate work it could become an issue.
Con Low maximum refresh rate of 60 Hz, less ideal for fast-paced action
Compared to some other gaming monitors, the iiyama G-Master Gold Phoenix GB2888UHSU-B1 isn't as fast as some of its competitors. The maximum refresh rate is limited at 60 Hz, which is the industry standard for all monitors. Some fast-paced games greatly benefit from a higher refresh rate such as 120 or 144 Hz as it increases fluidity.
Con 4K resolution doesn't scale well with all software
Due to the native 4K resolution and the relatively small 28 inch screen size, text can be hard to read in Windows and other non-gaming environments, such as Adobe's software. Not everything scales well in 4K (yet).
Con Color gamut settings need calibration
Out of the box, color settings aren't optimal. The display has some over-saturated green and under-saturated red, while blue has too much of a purple tint. Calibration is needed to improve color gamut.
Con Mediocre luminosity uniformity
The uniformity of the display in terms of luminosity is measured at 78% which isn't a bad result, but other displays with similar panels can certainly do better with scores over 85%. In short, uniformity is a bit flat and might be noticeable.
