TL/DR: Amazing monitor. Great picture, Great Features. HotKey Puck - the accessory I didn't know I needed, but can't live without! Wish it had 1 or 2 more USB ports & Ethernet port.
I shopped for a monitor for months. I have used dual 27" monitors for at least a decade. I've recently started to have trouble with vision - more than just my eyes getting old, but they are too. I thought getting a slightly larger monitor would be nice.
The Good:
The picture quality is really good and the features are fantastic. The display is plenty bright, without being too bright. It is flicker-free and has settings to minimize blue light. The color calibration is far more than I need. All the various color settings and features are interesting and cool. I don't really use them but did find them interesting enough to check out. There is also a boatload of software that you can download, including eye care software that reminds you periodically to look away from the monitor etc. All good things to help preserve eye health.
The Freakin' AWESOME
Hot Key Puck
The most exciting feature of the monitor is the hot-key puck. With other monitors that have a built-in KVM switch, the switch to changing computers is usually on the monitor itself - not always convenient or easy to reach. The hot-key puck has a 3–4-foot cord and allows you to navigate the on-screen menu without needing to reach the monitor. You can even customize the buttons (hotkeys). This handy-dandy device allows me to change the computer with a click of a button on the hot-key puck. While the cord is plenty long to be within reach without stretching, I do wish it was a tad bit longer or could use an extension cable, so that I could run the cord under my desk to minimize cord clutter. But that's a really petty complaint for a spectacular feature.
Monitor Arm
The monitor stand is an outstanding feature with a well-thought design. It is very similar to the Ergo Arm that has been used for a few years by another monitor brand. The monitor connects to the stand with a quick-release type of connection giving the back of the monitor a very finished look.
This arm has plenty of room in the arm to route your cables through it, IF you use thinner cables. If you like the braided cables, it may be a very tight fit that doesnt' allow all of them to fit. I highly recommend using non-braided cables for this arm as it provides a very finished look and minimizes cord clutter when all the cable route through the arm.
Putting it together can be a one-person job. For some, it may be helpful to have an extra set of hands to put the monitor on the arm.
Auto-detect orientation
I was pleasantly surprised to see that this monitor detects the orientation of the monitor and adapts accordingly. This is a feature that I did not see in the product description & was pleasantly surprised by.
Pro Tip:
The cables plug into the monitor from the bottom. Once you have the monitor connected to the arm, rotate the monitor to portrait orientation so you can easily see the plugs. Extend the arm so that it is at its farthest point in order to determine how much cable is needed. This will help prevent potential damage to the ports from extending the monitor farther than cords allow later during regular use.
The monitor sits roughly 3-4" from the back edge of my desk. This is the farthest back the monitor will actually go. if you have multiple monitor setups like I do, you will want to evaluate the position. This monitor sits on the right side. I initially thought that would allow me to have the most open space on my desk. That didn't work as the angle wasn't right. For multiple monitor setups, I recommend the arm be placed towards the main monitor to keep the best angle for us.
The meh
There is a single headphone jack on the side of the monitor. Since this monitor sits on the right side of my setup it is not a problem. If you plan to have other monitors to the right of this one, you may want to consider a right angle or u-shaped connector. I found these very helpful on my other BenQ monitor which is the center of my setup.
The Could-Be-Betters
There is no ethernet port. You can certainly use one of those ethernet-to-USB adapters and plug that into a USB port. I found that to be slower than when I plugged the ethernet adapter directly into my laptop. It also uses a USB port. Which leads to....
There are only 4 USB 3.2 Gen 1 ports (3 USB-A, 1 USB-C) for peripherals. 2 of these ports (1 USB-A & 1 USB-C) are on the side of the monitor. Those are easy to reach, but when in use, they prevent smooth alignment with another monitor for multi-monitor set-ups. 4 USB ports are typical of many, if not most, KVM switches, but fewer than I need. I have a USB hub connected to one of the ports on my monitor.
There is 1 display port and 1 HDMI connection. The KVM switch is preset to specific combinations: USB-C, USB1 & DisplayPort, USB2 & HDMI. Adapters might work, but there is limited space under the back cover. One quirk that I experience is that the monitor doesn't always switch to the video source via the hot key puck when waking from sleep or hibernate - specifically when i last used 1 laptop (which is now asleep) and am waking up the other from sleep. I have to use the buttons on the back - which are easy to reach as they are on the bottom right in both portraig or landscape orientation.
Prior to researching for a new monitor, I had never heard of BenQ. Given my experience with this product though, they have moved to the top of my list for future monitor purchases.
