Iiyama ProLite XB3288UHSU-B1 31.5in Professional Monitor Review

Rating: 8.0.

Although Iiyama is making some inroads into the gaming market, its core focus is still the professional user. The ProLite XB3288UHSU-B1 is another screen that's solidly focused on graphics work and business, with a 31.5in diagonal and 4K resolution. However, unlike most of ProLite range, it uses a VA panel rather than IPS.

The catchily-named XB3288UHSU-B1 bears the usual serious black design of Iiyama ProLite monitors. The basic specification is as expected for a VA panel, with a high 3,000:1 contrast and mid-range 300cd/m2 brightness. Pixel response is a reasonable 3ms, but this is no gaming screen – the maximum refresh at 4K is 60Hz, although you can get up to 75Hz below the native resolution, and AMD FreeSync is supported too.

While you do get two HDMI inputs and a single DisplayPort, there's no USB-C input. However, for a business environment there are built-in 3W stereo speakers as well as a minijack output for headphones. There's also a USB hub with a couple of ports on the side.

The level of adjustability is mostly comprehensive. You can vary the height, swivel the screen on its base, and tilt forwards and backwards. Surprisingly, there's no portrait mode, however. A label on the stand warns against it.

In other words, most of the basic necessities are there for the everyday professional. But most important is how well you can set this screen up for your particular activity and the image quality. So let's find out if this is another dependable professional workhorse from Iiyama.
