The Iiyama G-Master GB2570HSU box is typical for Iiyama's gaming screens – a bit more exciting than its business monitors.
Inside, you only get an HDMI cable, power cord and upstream connectivity for the USB port. No DisplayPort cable is included.
Like other Red Eagle monitors from Iiyama, the only real red is in the name and the removable label on the front. Otherwise, this is a predominately black screen. Sure, black goes with everything, but bling lovers will be disappointed.
Adjustments only include the ability to raise the screen up and down by 130mm, or tilt 18 degrees backwards and 3 degrees forwards. There is no swivelling. However, you can rotate the panel through 90 degrees on the stand into portrait mode.
As this isn't a curved screen, you might make use of this function when reading documents or in a multi-screen setup where it's handy to have interface elements arranged vertically rather than horizontally.
Connectivity covers most bases but isn't that generous. You get an HDMI port supporting version 2.0 of the standard, and the single DisplayPort meets the 1.4 standard. Both ports support a 165Hz refresh at Full HD, so it doesn't matter in this respect at least which type of cable you use. The USB hub is 3.0 level and only offers two ports, although that's adequate for neatening up and simplifying your keyboard and mouse cabling.
Next to the kettle power lead input is a minijack for audio output, including headphones. You will definitely want to plug the latter in, because the built-in 2W speakers are extremely weedy.
There aren't any fancy external pucks or joysticks for operating the menu on the GB2570HSU. Instead, you get a traditional row of six buttons under the bezel on the right-hand side with clear labels above so you know what each one does.
