Packaging and Accessories

We begin the review of Yeyian Sigurd 4000 placing a large and robust cardboard box on our work table that shows us its design on the front and its technical specifications on the back.

Inside, the monitor is very well protected by a thick cork frame that also organizes the accessories on a first level.

The set of accessories has on the one hand the user manual, a welcome card, some supports to make it compatible with VESA 75 and a headphone holder.

Yeyian Sigurd 4000 - Front view off

We place the base to continue with the review of the Yeyian Sigurd 4000 facing the monitor itself on our work table. We are faced with a model manufactured in black plastic mate that offers a front design without frames, at least in the three that is possible.

34 inch curved UWQDH

Specifically, the Yeyian Sigurd 4000 offers a dashboard 34-inch curved (1500R) in format 21:9 with a UWQHD resolution of 3440 x 1440 pixels. Thanks to your panel VA LEDallows to reach a 165 Hz refresh rate with a response time of 1 ms (MPRT). Obviously, it is compatible with the AMD FreeSync / NVIDIA G-Sync technology to take advantage of every last frame generated, especially when we cannot reach those 165 Hz in a stable way.

On the other hand, the panel specifies a contrast ratio of 3000:1a typical brightness 350 nits and a maximum brightness in HDR content of 400 nits.


In the lower margin, the brand logo stands out and, on the right, the serigraphy that indicates the functionality of each of the buttons that we find in the lower margin.


Yeyian Sigurd 4000 - Base 2

He Yeyian Sigurd 4000 It has a metal base with a rather aggressive design, very fashionable in gaming. This allows height adjustment and rotation on it, as well as inclination between -5º and +15º.

Minimun height

offers some dimensions of 318.3 x 200.1 x 85.3 mm with the basewhich are reduced to 318.3 x 143.0 x 51 mm without it, probably when we use a VESA 75 compatible mount.

Yeyian Sigurd 4000 - Red LED Strips

We turn the monitor to see how it offers three red LED lighting strips that reinforce that gaming aesthetic you are looking for. In addition, the inclusion of a rear support for headphones he finishes finishing it off.

Yeyian Sigurd 4000 tests

Yeyian Sigurd 4000 - Tests

We connect the Yeyian Sigurd 4000 to our usual test equipment through the included DisplayPort cable to start enjoying the benefits that this monitor offers us.

The first thing to note is that its 34-inch curved format makes it ideal for those looking for an ultra-wide screen, although it requires a certain period of adaptation from a flat screen. The 1500R curvature is correct and allows the sides to be brought closer to the eye, increasing the feeling of immersion in simulation games.

color analysis

Yeyian Sigurd 4000 - Colors

We have analyzed the colorimetry of the Yeyian Sigurd 4000 with our calibrator spyder5 to see how much of the different palettes it can cover. According to our tests, which are reflected in the following image, covers 100% sRGB space, 83% DCI-P3 and 87% AdobeRGB.

It is therefore a model that offers good colorimetry, but not enough to use it in design environments.

gloss analysis

We have also analyzed the level of brightness throughout the length and width of the panel, obtaining a result of 340 nits They are not too far from the promised, something that does not usually happen. In any case, higher intensity peaks are expected with HDR content.

In the same way, we must emphasize that it does not offer any major defect in terms of backlighting, no traces of bleeding, glowing or clouding with the brightness at maximum and the room in the dark.

Gaming Performance

test games

But the most important thing in the review of the Yeyian Sigurd 4000 it’s obviously his performance in games. Thanks to your 165 Hz refresh rate and his response time 1ms (MPRT), we can enjoy at a high level with a very low latency. Obviously, we will need a graphics card capable of releasing a good FPS rate in the title that we are going to play, although the technologies AMD FreeSync / NVIDIA G-Sync They will allow you to take advantage of the last FPS generated.

Latency with LDAT


We have analyzed the effective latency with the NVIDIA PCAT tool. As we can see, it is located in the middle area of ​​our table, quite correct for its market range.
