Viewing Angles

The GNV30CBXA looks a little better than most VA panels when viewed off-axis. The picture becomes a little cool and brightness is reduced by around 30% at 45 degrees to the sides. The top view is washed out with an obvious green tint.

The monitor’s relatively small size makes sharing impractical. The best image is seen when sitting 2-3 feet away, front and center. The stand lets you put the panel up high so it can be perfectly vertical, which keeps all parts of the image equidistant from the eye.

Our GNV30CBXA sample showed a few slightly visible uniformity issues. The sides of the screen were a tiny bit darker than the rest. The issue was easier to see in test patterns rather than actual content. In games, only the brightest scenes were affected, and then only when large fields of bright white were shown. This is likely a sample-specific issue, so your mileage may vary.

The GNV30CBXA’s biggest draw is its speed. It’s the fastest ultrawide you can buy for under $1,000, but there’s a caveat: Though the GNV30CBXA performed well in our tests, which use field patterns, the overdrive is not aggressive enough to eliminate all motion blur. Gameplay revealed a slight smearing effect when moving the mouse quickly. It didn’t distract too much, but this monitor’s gaming performance isn’t quite as smooth as other ultrawides we’ve tested.

Control response was no problem though. The 23ms score we recorded was corroborated by excellent gameplay. Aiming was very precise when tracking moving targets. Competitive gamers will certainly find that this Viotek is able to keep up.

    94 PPI might be sufficient for games, but not for the desktop for me.

    Agreed, for desktop use I personally prefer at least 100 ppi. For instance a 27 inch 1440p monitor has a ppi of about 108. A 31.5 inch 4k monitor has about 132 ppi. I also have a 55 inch CX OLED at my desk which is about 86 ppi, and its not bad at all because my viewing distance is about 50-65 inches away from the screen.
