Starting with a look at the GB2770QSU's design, I'd argue this is the most obvious way iiyama has kept costs down. It's not an ugly screen by any means, but the bezels aren't as trim as some others we have seen in 2021, particularly the thicker chin.
It's also made entirely from plastic, and that includes the stand. The monitor is pretty light as a consequence and I found the type of textured plastic used shows up fingerprints very easily – that's not really an issue for the back of the panel, but you will notice it on the v-shaped stand base.
Despite that, I couldn't see any parts of the construction that looked poorly done, and credit to iiyama as the stand actually comes pre-attached (with four screws) to the display itself. I also appreciate the addition of a small cable routing hook on the stand to keep your power and display cables tucked out of sight.
We can note the lack of a joystick however, so to control the OSD six buttons are placed on the underside of the bottom bezel. White legends are printed on the bezel itself so you know which button is which, but this is another clear cost-cutting measure.
The included stand offers a good amount of adjustability though. We see up to 130mm of height adjust, tilt from 18° to 3° down, and even the full 90% of pivot. Granted, the screen only pivots clockwise, but that's still a decent showing from the stand. The only thing really missing is swivel, but the GB2770QSU is light enough to quickly turn without any problems. You can always attach your own stand or arm thanks to VESA 100×100 mounting, too.
Looking now at the connectivity options, this is another indicator that iiyama had to walk a fine line to be able to offer this screen at its £250 price-point. There's only two video inputs, 1x HDMI 2.0 and 1x DisplayPort 1.4, a 3.5mm audio jack and a two-port USB 3.0 hub. If you're only connecting it to your PC, it is absolutely fine, but by modern standards just two video inputs – and no USB-C – could be seen as negatives by some.
