WOW!!! THE BEST MONITOR ON THE MARKET PERIOD!
The Dell 4025 40” 5k2k monitor is a super high resolution 5120x2160 monitor with a 120hz refresh rate and miniLED backlight so colors are borderline just as vibrant as OLED monitors, Blacks are truly BLACK, and although being the best monitor ever made for productivity, gaming on it is a one of a kind experience, because this is literally the only monitor on the market with such a high resolution that also has a 120 hertz refresh rate so gaming is smooth as the finest OLED gaming monitors available, but this monitor is higher resolution that any other monitor on the market short of the $6k resolution Apple ProRes monitor that costs over $6000, and the Dell 8k monitor that has higher resolution, but neither of these two aforementioned monitors have a high enough refresh rate to hold a candle to the smoothness offered by this monitor’s gaming prowess! You can’t go wrong with this monitor… Yes it is expensive, but it is WELL WORRH IT, and I could not be more pleased with my purchase! If you’re looking for the best of the best for Productivity but enjoy a little gaming on the side (in my case, Microsoft Flight Simulator is my Vice, then you owe it to yourself to give this monitor a try. I guarantee you won’t be disappointed. It is simply the best monitor currently on the market, PERIOD… Oh and I completely forgot to mention that it comes complete with a full fledged, full featured thunderbolt 4/USB/USB-C dock built in with at least 12 ports, a feature set that would cost an extra $300-$400 on its own as a standalone dock if it wasn’t built into this monitor, including 140W charging over USB-C/Thunderbolt, enough power to charge a brand new MacBook Pro at FULL SPEED! HIGHLY RECOMMENDED!!!!!!!!!!!!!

Great color, awesome size but a few cons...
For context, I have the LG 5K that Apple sold when they weren't making their own monitor*. The color on that LG is superb, the pixel density is superb (Retina display quality on the text), and the built-in camera is good (not amazing, but definitely good enough that I don't feel the need to buy anything else). Onto this Dell UltraSharp. Just to give context, the reason I was interested in this was primarily for the larger screen size. My Pros: 1. Screen size is awesome. Not too big to where I feel like I need to sit 10' back from my desk. 2. Color accuracy and depth. Just as good as my LG, which is superb. 3. Well made, well boxed/packaged, and very simple to put together. My Cons: 1. The biggest con for me is that I cannot control brightness or sound with my Apple keyboard on this monitor. I had to get a separate piece of software to be able to do that. Which was an additional cost. 2. The text renders at a 4k level, so it is noticeably fuzzy compared to my LG 5K...which is hard to give up once you've experienced it. 3. The speakers are absolutely pointless, they sound like tin cans (actually, tin cans may sound better). They didn't build a camera in, so maybe they should have avoided the speakers as well. 4. No built-in camera, so an additional cost there (since I need one for my job). But given how crappy the built-in speakers are, maybe this is a blessing. *Apple makes the enclosure and, I believe, works with LG to make the panel to their specifications.
