Iiyama G-Master GB3467WQSU review: first 34-inch monitor 165Hz @ 0.4ms

The Iiyama GB3467WQSU-B1 is inconspicuous, with only the stand opening the player’s side away from the monitor.

The Iiyama G-Master GB3467WQSU has a very classic design with well crafted matte black plastics. Only the Y leg slightly marks other screens of the Japanese brand and allows you to see the tilt. games this screen.

Impressive leg.

The Y-shaped leg is quite wide (55 cm at a depth of 28 cm). Fortunately, its branches are quite thin and free up a lot of space on the table.

Height and tilt adjustment.

Height and tilt adjustment.

This monitor offers over 13cm height adjustment and -3° to +20° tilt. Although the GB3467WQSU-B1 rotates nicely into portrait orientation, it is only used to transport the monitor. Indeed, the leg is not high enough to allow the panoramic plate to turn before it touches the table. You can put it in portrait mode, but then it is tilted back and this position is frankly of little interest, especially with a curved monitor.

The back of the monitor.

The back of the case is made of high-quality grainy matte black plastic. The connector is oriented downwards. The screen is compatible with 100 x 100mm VESA mounts after removing the stand. There is a fairly simple cable run at the base of the arm, allowing you to group all the wires together.

Connection.

The connection consists of two HDMI inputs, two DisplayPort inputs, a headphone output, and four USB 3.0 ports. The screen also has two 5W speakers, far from exceptional, but helping out even for system sounds and watching short videos.

The OSD menu is controlled by a joystick and special buttons for switching sources and adjusting the volume.

Iiyama has the foresight to use a four-way joystick, which is the most efficient way to navigate the menus. The OSD allows you to adjust brightness, contrast, gamma, color temperature, overdrive, FreeSync… but navigation is sometimes awkward. The monitor also has dedicated keys for switching sources and adjusting the volume, which is very convenient in everyday life.

On our 140 x 60 cm desk, the Iiyama GB3467WQSU-B1 takes up space well. The 27.5cm-deep leg takes up a fair amount of desk space, but its airy side leaves plenty of room for a keyboard and mouse. The Ultra Wide Quad HD resolution of 3440 x 1440 pixels is still a pleasure to use, whether it’s office tasks with a comfortable workspace or games where this resolution remains at a good average for today’s graphics cards. It is still necessary to provide a card that is powerful enough to properly use this resolution at 165Hz.



Iiyama has put a lot of effort into factory calibration as the monitor displays a very accurate image right after unboxing. With an average delta E of 2.3, colors can be considered faithful to the source colors, while gray levels are perfectly reproduced thanks to an average gamma measured at 2.2 and a perfectly stable curve across the entire spectrum. Only the average temperature measured at 7400 K is higher than the reference value (6500 K), while showing perfect stability. Fortunately, you can manually select the warm temperature setting and restore the average color temperature measured at 6340K, which is much closer to the reference 6500K. We also lowered the brightness to 23 to get a white level close to 150cd/m². These two modifications in themselves improve image quality even more, because at an average Delta E value of 1.7, the colors are still slightly more accurate, in particular blue and red colors, which pass below threshold 3 – a value below which the eye cannot sees. distinguishes colorimetric drifts longer. Above this value, only green remains, all other colors are ideal. Calibration with a probe allows for very little improvement in rendering, but it can be easily dispensed with.

With a native contrast ratio of 2860:1, the monitor displays very deep blacks, much deeper than on an IPS monitor, which is often capped at 1200:1 contrast ratio. This contrast ratio remains slightly lower than the best VA monitors on the market, such as the MSI Optix MAG271CR or Philips BDM4037UW, which have a contrast ratio of over 4000:1, but still produce quality blacks. Oled technology remains the benchmark in the field, but it’s still too sensitive on PC monitors to be the benchmark.

The average difference in white uniformity is very good. We measured it at just 9% across the entire 34-inch panel. Thus, there is no difference in brightness perceived by the eye. We did not notice any light leaks in the corners or any turbidity (“cloud effect”) on our test model. The VA technology also offers good viewing angles with very little change when the user is no longer in front of the screen, which rarely happens with a curved model designed for front use.

Iiyama G-Master GB3467WQSU-B1 does not use pulse width modulation (PWM, “Pulse width modulation“) to adjust the brightness so that it does not flicker and cause headaches for those who are sensitive to this phenomenon. Iiyama also offers a blue light reduction software mode via the OSD.

This monitor supports FreeSync (and by extension G-Sync) from 48 to 165 Hz and therefore performs best when the graphics card is sending between 48 and 165 frames per second. To take full advantage of this monitor’s capabilities, you’ll need a powerful graphics card, specifically to display 165 images per second at native resolution (3440 x 1440 pixels). A graphics card like the GeForce RTX 3080 12GB or the Radeon RX 6800 XT seems like the bare minimum. You can even choose higher performance for the most demanding games. In all cases, there is fluidity and there are no problems with image breaks (tearing) or jerks (microstuttering).

We measured an afterglow time of 4.5ms with overdrive (“Response Time” in French in the OSD) set to “5”. The various suggested levels have very little or no effect on the screen. The Iiyama G-Master GB3467 is one of the most sensitive VA monitors on the market. It is on par with the 27″ Samsung Odyssey G7 and 49″ G9 equipped with a 240Hz VA panel and almost competes with the fastest models equipped with a TN panel such as the Alienware AW2518HF 240Hz flashing at 3ms, but its The VA panel is much better (viewing angles, contrast). Display latency, measured at 10.1ms (at 60Hz), results in almost zero latency between an action performed with a mouse or keyboard and its effect on the screen.

Conclusion

we tested we liked it

How does assessment work?

The Iiyama G-Master GB3461WQSU-B1 is a great monitor, very versatile and suitable for both gamers and workers. The former benefit from impeccable response (the best on a VA panel), 165Hz frequency and FreeSync compatibility, while the latter enjoy the workspace available on this 34-inch panel, image quality (accurate colors, high contrast) and thoroughness. ergonomics. Add to that the low power consumption and four USB 3.0 ports, and for this monitor from Iiyama, it’s almost flawless.
