The first 4K IPS Black technology, Dell U2723QE monitor experience

Whether it is personal purchase or corporate purchase, when purchasing monitors, the appearance rate of the Dell brand is quite high.

Looking around in Aifan'er's office, Dell's monitors really took up most of the workstations. And most of the Dell monitors can be seen at a glance that they are U series.

Elegant appearance, good look and feel, and good reputation make Dell's UltraSharp a long-time favorite of professional users.

Therefore, when I silently tidied up the workstation, slowly unpacked, and put a new Dell monitor on the table, I still attracted envious glances from my colleagues in the editorial department. (Except for a few colleagues who use iMacs and alien displays)

After all, this is the latest iteration of Dell's UltraSharp line of 27-inch 4K monitors – the U2723QE. As usual, it will be one of the first-order products for many users who are planning to buy a 4K professional monitor.

Elegant appearance in silver and white tone, although not outdated but not stable enough

For a long time, the design of Dell monitors has been an elegant, beautiful and highly recognizable type in the industry. Basically, I can easily identify the stand of the Dell monitor from a distance, and then look closely and confirm the DELL logo on the stand.

Dell's new U2723QE monitor not only introduces a new color tone, but also drastically changes the design of the stand and base.

The first is color matching. In addition to the original dark gray and dark tones, U2723QE also provides silver and white bright color matching paint options. The color tone of this set is basically the same as that of the silver-white aluminum alloy body of Dell's own XPS ultrabook and Lingyue ultra-thin notebook.

The monitor stand has become slimmer than the classic old model. It is the same platinum and silver color as the back panel. The cable hole is reserved below, but the cable hole position has become a rectangular style.

Dell's lift bracket still supports lift adjustment (150mm), 30° horizontal rotation of the central axis, and 360° screen rotation. Whether it is lifting or rotating, the damping is very appropriate, and it feels very ergonomic to use.

However, it should be noted that when you want to rotate the screen vertically, you need to tilt the screen up a bit before you can rotate it. Otherwise, even if the screen is lifted to the highest position, the corners of the screen will collide with the desktop. This is clearly indicated in the manual.

However, the stability of the U2723QE's stand is obviously not as good as that of the old model. The screen of the U2723QE will shake obviously if it touches the monitor slightly or encounters the shaking of the desktop. This happens frequently in my experience. If it is used with a desktop lift bracket, the vibration when hitting the keyboard will also make the screen shake.

If you plan to install a third-party pneumatic bracket, the Dell U2723QE also reserves four VESA standard holes and screws.

The physical buttons of the U2723QE are placed on the back of the fuselage, which simply provides a power switch button and a five-way rocker button.

Pressing the joystick button will pop up the settings menu. In order to adapt to the joystick interaction, Dell has added a set of quick adjustment menu interaction methods. The traditional settings page is hidden in the next-level menu, and you can enter it by dialing up.

With the contrast, you can perceive the obvious changes of the new model. If you want to simply adjust the brightness and contrast of the display or the input source, you can directly toggle it in the quick menu for a few times. Compared with the traditional setting menu, it is more efficient and less troublesome. few.

The magnetic snap mounting holes on the bottom speaker bar, which were absent from the previous generation, reappeared on the bottom of the new model and are compatible with Dell's official speaker bar accessories (SB521A).

The screen part on the front of the display still adopts a matte screen design, which can effectively reduce glare.

The narrow border design with almost the same width on all sides completely cured the obsessive-compulsive disorder. The DELL logo at the bottom of the screen in the past also made way for simplicity. It completely disappeared from the screen border and ran to the bracket below.

90W USB-C is a fresh recipe, you can eat it all over the world

A complete lineup of interfaces has always been one of the advantages of Dell U-series monitors.

The video transmission interface of Dell U2723QE provides DP1.4 and HDMI2.0 ports. There is also a full-featured USB-C upstream interface on the back (USB3.2, DP1.4, 90W power supply), 4 USB-A 10Gbps ports, and a 3.5mm audio output port.

The USB-C upstream port has also returned, which means that the 23Q supports the KVM connection function, that is, after a set of keyboard and mouse peripherals is connected to the monitor, it can control two different devices with the switching of the display screen.

▲ Daisy-chain connection to another 4K monitor Picture from DELL

The Dell U2723QE can also use Display Stream Compression (DSC) technology to daisy-chain another 4K monitor via the USB-C port and display at full resolution. This is a very designer friendly feature.

Rarely, Dell U2723QE also prepares an RJ45 Ethernet port, which can directly provide wired network connection to the notebook.

It can be seen that the expansion interface of the Dell U2723QE is quite well prepared, which is equivalent to integrating a USB HUB expansion dock directly into the display.

The best way to connect the laptop to the monitor is to use a USB-C cable to connect to the full-featured USB-C port on the back of the U2723QE. A high-quality USB-C Gen2 5A cable is also included in the box.

I don't know what Windows users will think, but I think this "full-featured USB-C docking station" integrated into the monitor will definitely be a favorite of MacBook users.

Through this interface, the device can transmit video signals and USB data at the same time, and can also obtain up to 90W of charging power.

That is to say, when I connect the MacBook Pro to the U2723QE, in addition to the screen expansion and the interface expansion, the MacBook Pro will also receive power. On the entire desktop, there may be only such a line left.

Such a desktop is very neat and efficient to use. According to my usage habits, when I come to work in the morning, I only need to take out my MacBook Pro, connect this USB-C, I can light up my monitor, and also connect to other peripherals tied to the monitor. , even connecting the MacBook Pro directly to the company's wired network.

To go to a meeting, or when you get home from get off work, gently unplug this USB-C cable, and you can take your MacBook Pro and leave gracefully.

It is commendable that Dell provides a 1A1C high-speed data interface at the bottom of the display (the previous interface was on the side of the screen). The two ports can not only provide 10Gbps high-speed connection, but also provide up to 15W wired charging.

▲ You can use this interface to connect SSD mobile hard disk

▲ High-speed transmission is still possible after connecting the SSD mobile hard disk

It is very practical to use these two interfaces to connect mobile hard disks, to charge wireless keyboards and mice (Magic Keyboard & Magic Control Board), or to recharge mobile phones. However, if the 3.5mm interface can also be moved to this position, it will be more convenient to connect external wired headphones.

In total, the entire Dell U2723QE provides 6 USB downstream interfaces, and this USB HUB is also very competent.

The new technology of the first LG display allows IPS to be darker

At CES2022, LG Display showcased the latest IPS Black display technology. This is a technology that allows IPS panels to obtain higher contrast ratios. Generally speaking, it is to allow the panels to obtain deeper effects when displaying black content, and the display characteristics are close to OLEDs that do not emit light.

However, the first display equipped with this technology is not LG, but Dell.

The panel model used by Dell U2723QE is LM270WR9-SSA1, and its static contrast ratio can achieve 2000:1, which is much higher than the 1300:1 static contrast ratio of the previous generation U2720Q.

In LGD's words, the IPS Black panel has 35% deeper black levels than existing IPS products, while still guaranteeing extreme sharpness and precise color accuracy.

From the actual look and feel, the contrast ratio of the U2723QE is obviously higher, indeed deeper, and the screen does not look so gray. Under the condition of keeping the same viewing angle range, its look and feel is much better than the previous IPS panel.

Of course, users who choose Dell U-series monitors pay more attention to its most advertised color accuracy.

In the box, Dell still provides a factory screen calibration report to ensure that the factory calibration ΔE<2 (average). However, compared to the previous generation, the calibration report of the U2723QE also adds calibrations for three color gamut spaces, Rec.709 and P3, in addition to sRGB.

We can see with the Starscream SpyderX Elite colorimeter that the color gamut of this screen has reached 100% sRGB, 95% P3 (subsequent warm-up retest can reach up to 98% P3, reaching the official nominal value ), the minimum ΔE value is 0.50, the maximum is 2.3, and the average value is around 1.2.

To sum up the above parameters in one sentence, the color performance is very accurate, and it also has top-level P3 color gamut coverage.

It also confirms that the IPS Black technology panel does not affect the performance of color accuracy while enhancing the contrast.

Thanks to the high coverage of the P3 color gamut and the 4K high-definition resolution (3840×2160) that supports HiDPI rendering, the U2723QE can perfectly restore the color of macOS and high-definition Retina display.

Next, let's pick the shortcomings of the U2723QE.

The first is that it passes VESA DisplayHDR though ™ 400 certification, the maximum brightness can reach 440 nits, but its HDR display effect can only be said to be unsatisfactory (barely satisfactory).

The main reason is that the panel of the U2723QE is a side-mounted partition backlight design, but it only provides 4 partitions to choose from. When watching videos, the partition light control strategy is relatively normal, the brightness is significantly increased, and the color performance and dark detail performance are OK. .

However, if I play HDR games, the interference of a large area of ​​light beams will be more obvious, especially when switching between light and dark scenes in FPS games, which greatly reduces my enthusiasm for playing games. Ok? This seems to be what the bosses want to achieve?

It is worth mentioning that this panel has the characteristics of hardware low blue light, and has passed the hardware low blue light and no flicker certification of TUV Rheinland. And as far as we know, this screen is DC dimming under SDR display, and high-frequency PWM dimming when switching to HDR display.

So, the U2723QE is a monitor designed for professional workflows, with top-notch picture clarity and color accuracy.

It is suitable for users like me who need to browse the web for a long time and deal with graphic retouching and text work.

PIP/PBP split-screen display, productivity/iQiyi idea

Dell U2723QE supports PIP/PBP split screen function.

PBP can divide the screen into two, and display the images output from two different source devices on the left and right sides of the screen.

While displaying Mac, while displaying WIndows

Display the Switch game screen while displaying the computer.

However, when PBP is turned on on a 16:9 screen ratio, and the screen of the two devices is displayed on a split screen, I think this effect and experience are still not as reasonable as the fish screen.

PIP is also called Picture-in-Picture. After the main source is displayed on the large screen, a small window picture of the secondary source is embedded in the screen.

The U2723QE provides a four-corner window, with a total of eight PIP split screen options.

Using the PIP window to embed a Switch game window seems to be a new way to catch fish at work. Anyway, use PIP/PBP for productivity, or iQIYI, It's up to u.

Still the 4K IPS monitor that pros love

When it comes to the model of Dell monitors, many people may find it complicated.

What we experienced this time is U2723QE. The suffix of QE represents the commercial series. A 1.8m DP cable is standard in the box. The corresponding home series model is U2723QX, and a 1.8m HDMI cable is included in the package.

While the two models differ only in the included cables, the panels and features remain the same.

To sum up, from the perspective of product iteration, U2723QE is the iterative replacement product of U2720Q with "increased quantity without price increase".

Because the new U2723QE not only inherits the accurate color and high-definition display performance of the previous generation in the same price segment, but also introduces the new 4K IPS high-contrast technology. Just from the quality of screen performance, it is already the best choice for this gear.

Coupled with the complete high-speed data interface and USB-C one-line connection function, not only can it be easily compatible with the large-screen expansion of notebook computers, but also allow notebook computer users to save money and desktop space required for expansion docks.

Therefore, if you are looking for a 4K IPS display with excellent color accuracy and no FPS game requirements, the Dell U2723QE will be a good choice.
