Everyone, what kind of monitor do you use when gaming or working?

The 『Jlink ‎D34QR4K』, which we are reviewing this time, has a WQHD and high resolution, a 144Hz high refresh rate, and is an ultrawide curved monitor. It is recommended for those who not only work normally but also need a lot of information at once, such as in fps games, or those who play games where victory or defeat is decided in an instant!

Review

Large Power Adapter

『Jlink ‎D34QR4K』
The power adapter is surprisingly wide.
Mr.ガジェット

The power adapter is honestly large and gets in the way.

Easy to Install.However, I wish the instruction manual was more detailed.

Simply place the base and stand and tighten with screws.

Mr.ガジェット

The base and stand were easy to install, but I struggled a bit with connecting the monitor body to the stand personally.

By the way, the instruction manual does not provide detailed instructions on how to install it.
It is fine for those who are used to installing monitors, but be careful if you are not.

You can’t really see it in the pictures, but…

Monitor Settings are Complicated

The monitor settings and power on/off are done using this function button on the back of the monitor.

Pressing this function button once brings up the monitor settings screen.
As shown in the image below, pressing it to the left corresponds to BACK and pressing it to the right corresponds to ENTER.

It’s great that there are gaming settings.

Mr.ガジェット

It was tiring to have to reach behind the monitor every time I wanted to change the settings.

Speaker Sound Quality is Not Great

『Jlink ‎D34QR4K』

There are two speakers at the bottom of the monitor and one on the back.

It’s not particularly bad when using it normally, but if you ask me if the sound quality is good, it’s not.
I don’t think anyone is expecting sound quality from this monitor, but I think it’s better to buy external speakers.

Display That Expresses Vividly

Mr.ガジェット

It’s hard to convey in pictures, but for reference…
It expresses very beautifully, so I didn’t feel any dissatisfaction with the resolution or color.

Curved Ultrawide Displayis Amazing

First of all, it’s incredibly wide at 34 inches, so you can display multiple screens and work.

When displaying three screens on 『Jlink ‎D34QR4K』
Mr.ガジェット

I was able to work without feeling any discomfort when displaying multiple screens!

Also, the curved display expands your field of vision and reduces the burden of moving your eyes!

The narrow bezel makes it easier to concentrate on gaming and work.

Mr.ガジェット

A narrow bezel is an important point.
The amount of information that can be displayed at once differs depending on the size of the bezel, so I think it’s a big advantage for people who play fps games.

High Refresh Rate. 144hz!

As mentioned in the specifications, the 『Jlink ‎D34QR4K』 supports 144Hz.

Mr.ガジェット

I was surprised by the smooth images!
Also, a high refresh rate is essential for games where a split second decides the outcome, so 144Hz is a welcome feature!

Summary

Overall, it has a high level of completion!

After using it this time, I felt that this 『Jlink ‎D34QR4K』 has few major drawbacks.
The resolution and refresh rate are both high, and it even has built-in speakers.
Also, the interfaces are well-equipped.

And above all, the feature of this monitor, the curved ultrawide display, has many advantages and few disadvantages, so I think it’s a monitor that I can recommend to anyone!

However, those who play fps games and the like will be able to make the most of this feature, so I especially recommend it to those people!
