[USB-A 4-Pin] I was looking for a large, high DPI monitor and there aren’t very many good options. I almost sprung for the Apple Pro Display XDR but I’m so glad I didn’t. This one is totally fine, it’s not quite as bright and clear as the Studio Display I use as a vertical monitor next to it, but it’s close enough for saying it was 1/3 the price of a Pro Display XDR. And it isn’t as ugly in person as it looks in the pictures.

[0.505 lb] We put them in some conference rooms and had good results. One room that is loud with heating A.C. devices needed a little tweak up on the mic but it was easy to configure. Plugin by USB is very convenient. It is nice to set and forget a device like this.

[USB-A 4-Pin] I bought this Dell Slim Soundbar to pair with a Dell Monitor and HP Mini Tower pc that I bought from B&H in December. It's adequate for listening to Zoom conversations, YouTube videos, and other normal workday functions. I wouldn't call it premium sound, but then the price would likely be significantly higher for an upgraded sound system.

[USB-A 4-Pin] I wish there were more 6k options on the market, but this is the only option against the Apple XDR. I wish the non-removable telescope of a camera didn't exist on this thing, but the display is great.

[0.505 lb] I've split my productivity and gaming setups for years. And this display represents a significant leap toward an eventual convergence.

For productivity, I typically use a semi-recent Mac connected to some kind of Apple-sanctioned retina display. While for gaming, I typically run a custom-built Windows PC and some kind of 1440p+ monitor running at or above a refresh rate of 120hz.

Recent improvements to Linux have made it easier for me to supplant macOS and Windows with a single software base, and the commodity hardware available for Linux systems–muck like Windows systems–is a big plus for me.

However, the display has always been a weak point. The lower PPI of non-retina displays distracts me from my productivity and will eventually result in strain given extended use.

But this monitor hasn't quite closed the gap for what I'm looking for. One day, I hope to have the best of both worlds. A retina display with excellent color and a high refresh rate that works well with commodity hardware. Until then, this is my favorite monitor on the market.

[4.94 oz / 140 g] I bought these to replace aging monitors in our office. The near-frameless design and almost zero bezel, makes them a good fit on our desks especially where we have triples installed. The nice variety of connection options makes adding them to docks a breeze. Great Dell quality (so far). Tilt, swivel and height adjustment is very much appreciated. 1920 x 1080 display size keeps things at reasonable size for my older users with failing eysight.

[USB-A 4-Pin] These are pretty cool. They are magnetic and just attach to the bottom of the newer Dell P series monitors. Pretty slick little things.

[USB-A 4-Pin] The HDL300 exceeded our expectations.
When hosting video conference calls in our ~25'x20' room, the audio pickup was clear and noticeably exceeded the quality we got from our Polycom Trio 8800 with external mics. When using an audio bridge for dial-in, the ability to pick up voices anywhere in the room was clearly better than the Trio 8800, but the audio quality did drop to conference phone quality due to the compression done by the audio bridge codecs/telco providers.
We have a white noise generator in our office space and a moderately noisy A/C unit in the room, as well as in-ceiling speakers which we play the audio through. The unit does an exceptional job at filtering out the background noise and preventing feedback, while leaving voices audible. The audio sounds natural and not overly processed like some conference phone's noise-cancelling algorithms, which drop audio if there is a cough, for instance.
We don't use the built-in speakers, but they seemed to offer good quality sound during our initial testing.
Installation and configuration was fairly easy if you're even a little bit handy.
We paired it with the Logitech Rally camera and were very pleased with the results.
If you're struggling to be heard, and this is in your budget, I don't think you'll be disappointed.

[4.94 oz / 140 g] I edit images for printing, and this 1440x2560 monitor is perfect. Large color gamut, bright, superb contrast…. Pleasant surprise: the number of connecting ports (this is not the Thunderbolt port model). Delighted with my choice.

[0.505 lb] Mounts with a pair of magnets, plugs into a USB port on the monitor. You have to plug in the USB-C cable to the computer (which also carries video as well as USB). To get it to work with an M2 Mac Mini, I had to install Dell's DDPM app for the U2421E - otherwise none of the USB ports worked on the monitor.
