This is Dell's upgraded work-from-home monitor that does a little bit of everything well. Like its cheaper sibling, you plug one Thunderbolt cable into your laptop and get power (140 watts, enough for big laptops), picture, internet, and USB accessories — the whole desk runs through one wire. But this one adds a 120Hz refresh rate, so scrolling feels smoother and casual gaming doesn't look choppy like it does on a regular 60Hz office screen.
The 27-inch 4K picture is sharp enough to fit lots of windows side by side, and Dell's IPS Black panel gives you deeper contrast than most work monitors — darker blacks in dim scenes without looking washed out. The HDR 600 rating means bright highlights in photos or videos actually stand out a bit, though it's still not the full punchy effect you get from OLED.
Colors come tuned from the factory, so if you edit photos or video the picture is accurate without tweaking. The 2.5G ethernet port is faster than normal if your network supports it, and the extra DisplayPort out lets you daisy-chain a second monitor if you want.
