iiyama G-Master 45″ Ultra-Wide 165Hz Curved VA Monitor Review

Display Analysis

This monitor was given a rating from iiyama that it can cover 100% of sRGB, which we can see is true, and 80% of the NTSC (which is broadly similar to AdobeRGB), which we can see is also true at 81%, it can also cover 89% of the DCI-P3 colour, which is decent, not as high as say, a modern IPS or OLED, but certainly respectable coverage for SDR content. The panel has a HDR mode that pushes this higher, but being an edge lit panel, the actual HDR is more about extended colour than actually providing much more dynamic range, but this is common on panels like this.

There are multiple profiles and gamma settings on this panel, and honestly, they’re pointless, as the default settings are right on the money, scoring a perfect 2.2 on the Gamma.

There’s some deviation in the grey ramp, but while it looks like a roller coaster, it’s actually a very tight tolerance of a little over 100 Kelvin, and overall, this is a rather excellent result, if a little above our ideal target of 6500K.

The monitor was rated for 400 nits brightness, but even in SDR mode, it managed to hit a very impressive 482 nits peak brightness, which is around 2.5x as bright as what you would get on your run of the mill mid-budget office monitor.

I only perform a colour calibration if its needed, but right out of the box, colour accuracy is fantastic. Anything under 5 Delta-E is good, 3 is very good, and 1 or less is extremely accurate, and this monitor averages just 0.96. The blue is a little high, but still well within our target, and can easily be improved by simply setting the colour temperature to “warm” in the OSD. Beyond that, I wouldn’t suggest changing any of the default settings.
