A home office setup can be judged on two things, and only one of them costs money. The first is the position of the monitor on the desk: its height, how far back it sits, and its orientation relative to the window. This can be corrected in a few minutes, using what is already there. The second is the monitor itself, its display area and resolution.
The order matters. A larger monitor, placed too low or facing a window, recreates the working conditions it was supposed to improve, only in a more cumbersome form. Adjustment does not replace a suitable monitor, but it determines what that monitor will deliver once it is installed.
Setting the monitor at the right height at home
The starting point is simple. The top of the display area should be at eye level when seated, so that your gaze naturally moves slightly downward toward the content rather than upward. This reference point can then be adjusted according to how it feels, depending on the user's height and the height of the chair.
At home, the furniture often makes things more complicated. A dining table is higher than a desk, and a kitchen worktop even more so. When the chair cannot be adjusted in height either, the entire difference is transferred to the neck and shoulders.
Three solutions are available when the monitor stand cannot be raised.
-
A riser placed under the base, provided it is stable and wide enough. A stack of books rarely stays in place for an entire working day.
-
A mount attached to the back of the panel, using the standard mounting pattern found on most monitors. An articulated arm provides height, depth and orientation in a single piece.
-
A monitor whose stand slides vertically along its column, which solves the issue at the source.
This information can be found on the product page, not in the photo. The 28.2-inch IPS 4K UHD+ Desktop Monitor specifies a height-adjustable stand, while the 34-inch IPS UWQHD Curved Monitor – White specifies height adjustment. How to read this information, including the adjustment range and tilt range, is explained in detail in our article on how an office monitor should be adjusted.
Viewing distance and the window: two constraints at home
The viewing distance is adjusted by moving the monitor back until the entire display can be read without moving your head, while the text remains sharp at the usual display size. A wide monitor mechanically requires more distance than a compact monitor.
The depth of the work surface therefore limits the diagonal, and this is the real criterion for monitor size at home. On a shallow desk, a very large format is viewed from too close, forcing your eyes to scan across the display. Monitor size is discussed in detail, with supporting figures, in our article on what monitor size to choose.
Then there is light. A window behind the monitor forces you to work against the light; positioned in front of the workstation, it reflects off the panel. The least disruptive position is generally to the side, with the monitor turned so that its surface is outside the path of the incoming light.
French rules applicable to workstations with display monitors follow the same principle. They do not specify a minimum size or resolution. They require a monitor that can be easily rotated and tilted, with adjustable luminance or contrast, and an image free from disruptive reflections.
What a day of remote work asks of a monitor
A typical day involves four tools in parallel: video conferencing, office software or a spreadsheet, instant messaging and a browser. The issue is less whether they can be displayed than how many windows remain visible at the same time without reducing the text to an unreadable size.
A 4K monitor can accommodate four windows in quadrants, each with a usable area equivalent to a full Full HD monitor. Switching from one application to another can then be done with your eyes, without keyboard shortcuts or overlapping windows.
The two uses do not require the same thing. Long documents, spreadsheets and web pages benefit from height and fine text rendering. Video conferencing with screen sharing benefits from width, since it occupies a fixed window while the rest of the work continues alongside it.
Display area describes what can be placed side by side, nothing more. What each person gets from it depends on their job and their way of working, and no general measurement can predict this.
Text sharpness: the calculation that settles the matter
At a constant viewing distance, character sharpness depends neither on diagonal size alone nor on resolution alone, but on the relationship between the two. This ratio is known as pixel density and is expressed in pixels per inch. It can be calculated directly: the diagonal of the pixel matrix, obtained by taking the square root of the sum of the squares of the width and height, divided by the monitor's diagonal in inches.
Here is what this calculation gives for the most common configurations on a remote-work setup.
Diagonal: 23.8 inches
Resolution: 1,920 x 1,080
Density, in pixels per inch: 93
Diagonal: 27 inches
Resolution: 2,560 x 1,440
Density, in pixels per inch: 109
Diagonal: 31.5 inches
Resolution: 3,840 x 2,160
Density, in pixels per inch: 140
Diagonal: 28 inches
Resolution: 3,840 x 2,160
Density, in pixels per inch: 157
At the same resolution, the larger the monitor, the lower its pixel density. The 27-inch IPS 4K UHD Desktop Monitor reaches 163 pixels per inch, the highest value on this list. The same number of pixels spread across 31.5 inches drops to 140.
At a high pixel density, characters are rendered using more pixels, so their outlines are more clearly defined, and a document displayed at its actual size can be read without magnification. The trade-off is that a high pixel density requires operating-system scaling to be enabled so that the interface remains a usable size.
The intermediate levels cover most home office setups. The 27-inch IPS WQHD Desktop Monitor delivers 109 pixels per inch, while the 23.8-inch IPS Full HD Desktop Monitor delivers 93.
One large monitor or two monitors
Both setups exist in remote-work environments and do not meet the same needs.
A single large monitor provides a continuous surface, without a bezel in the middle of the field of view. It is suited to working on a wide document, an extensive spreadsheet or editing software, where a break in the middle is disruptive. The 34-inch IPS UWQHD Curved Monitor follows this logic, with enough width to accommodate three windows side by side.
A dual-monitor setup physically separates the workspaces: video conferencing on one, work on the other, without having to rearrange windows for every meeting. The central bezel is the price of this separation, while the layout that remains consistent from one day to the next is its benefit.
The choice between the two depends on how you work. One practical point often settles the matter: desk depth, which determines the available viewing distance, and the space left for a second stand.
A single cable between the laptop and the monitor
When the workstation is powered by a laptop, USB-C connectivity reduces the number of cables to plug in each morning. A single cable carries three separate streams: the video signal, data from peripherals connected to the monitor's hub, and power for the computer.
The relevant JAPANNEXT monitors indicate the charging capacity in their product names, in the form of a 65 W value. This is the case with the 28-inch IPS 4K UHD USB-C Desktop Monitor and the 23.8-inch IPS Full HD USB-C Desktop Monitor. This power level covers common ultraportable laptops, but the required power depends on the computer: each manufacturer publishes a minimum threshold for its models, and this is the threshold against which the monitor's power rating should be compared before purchase.
How this power delivery works, its limitations and how to read the specifications are explained in detail in our article on USB-C Power Delivery charging.
