Style: 28" 4K IPS | 3:2 | Ergo Arm | 90W USB-C
Pro’s: amazing vertical resolution on this monitor; those extra 256 pixels really come in handy. The aspect ratio makes it very useful to put side-by-side terminal windows for multiple machines. Quite a great monitor for productivity. The version with the Ergo arm has decent reach and makes it easy to turn to portrait orientation. Note that the portrait orientation only works in the counterclockwise direction, and that there is no way to set the monitor with the Ergo arm to the counterclockwise direction. While I originally expected to buy two of these monitors to use in portrait orientation, I no longer expect to do this given that a portrait orientation causes these monitors to be quite tall even at 28 inches. The last pro to mention is the beautiful and sturdy packaging of this monitor. BenQ makes incredibly intricate and robust packaging for all their products, from light bars to lamps. Cons: The color rendition of photos is quite lacking. There are often blown highlights compared to reference monitors like the Apple Studio display or the MacBook Pro m1 rscreen. The gamut of this monitor appears quite limited. Bright areas seem to have blown highlights rather quickly. I would not recommend using this monitor for any sort of photo or video editing. Many of my photos needed re-editing on a calibrated monitor despite using the Mac OS default color profile for this monitor. Other significant con would be that the price of this monitor has significantly increased over the last couple of months, possibly due to.

Working great so far. Text/color is very clear and easy on the eyes. I use this vertically, lot more space for coding. Recommended

Style: 28" 4K IPS | 3:2 | Ergo Arm | 90W USB-C
Pros: The text quality is outstanding sharp and clear, perfect for extended coding sessions. The monitor is heavy and pairs well with a strong monitor arm. The screen size allows for better productivity, displaying more lines of text at once. It reduces fatigue even after hours of work, making it ideal for tasks involving extensive text editing. BenQ Display Pilot 2 software works well on macOS. Cons: Although the monitor arm is sturdy, the monitor shakes slightly. The built-in speakers are of poor quality, with sound resembling mono output. The Display Pilot 2 software has minor glitches when used on Windows. A vertical line appeared on the left side of the screen, which seems to be a defect in this particular unit. Conclusion: Despite the defect in this unit, I would recommend this monitor to anyone working extensively with text due to its superior display quality and ergonomic design. I plan to exchange it for another one and give it another chance.

Style: 28" 4K IPS | 3:2 | Ergo Arm | 90W USB-C
It’s hard to believe that at this price point, the performance still falls short of LG’s years-old UltraFine series designed for Apple. As the marketing claims, there are indeed many software-based controls, but the most important one—automatic brightness adjustment—is far from smooth. The daisy-chain feature is essentially useless. Not only is it incompatible with Apple’s M-series Macs, but its bandwidth isn’t even sufficient to drive another 4K display on Windows. In other words, this so-called daisy-chain capability is nothing more than a joke. Color management for M-series MacBooks is also inferior, failing to meet expectations for a monitor at this price tier. The good thing is the panel is decent, if the price dropped to 300-400, that is more reasonable.

Monitor is first-rate and has no complaints. The backlight is superb, and I’m not sure how I managed without it. I work 10-12 hours a day on the computer, and my eyes used to get strained using my old monitor. Since switching to the BenQ, all eye strain has disappeared. As a side note, I did have to cut a hole in my desk because the arm (which is fantastic) required more lip than the desk I had to attach it to. However, it’s still well worth it.

For coding, this is perfect. Good 3:2 view port and high density pixels, the screen can display more than 80 lines of code in the same page without making fonts too small. It support usb c power delivery and dock as a result, I get rid of the usb c dock I use on the table. The power cord is a simple one, as a result, it doesn't put a huge adaptor on the table either. Reasonable cable management so the table is much clearer and usable compare to my previous set up.

The monitor itself is great, the quality overall is horrible. After a short time, I had broken pixels with TWO models, resulting in a permanent horizontal line in one case, and a permanent vertical line in another case. Of course, now I am outside the return window, and I didn't buy extended warranty. Now we'll see whether I can get this thing replaced under warranty, but I would rather have my money back instead.
