One cable for the picture, the power and the monitor's USB ports. Five picks, each confirmed on the maker's own spec page.
Turn your laptop's power brick over and find its rating in watts. That's your target. A monitor that supplies the same or more will run the laptop and charge it at its normal pace. One that supplies less will usually still charge it, only more slowly, and a laptop working hard can lose charge while it's plugged in.
Thin-and-light laptops often come with 45W to 65W chargers, so 65W covers most of them. Bigger laptops with dedicated graphics may want 100W or more, and many gaming laptops use a separate barrel charger that no monitor can stand in for.
A USB-C socket on a laptop doesn't promise video. You need one that carries DisplayPort Alt Mode or Thunderbolt; look for a small DisplayPort or lightning-bolt symbol beside it, or check the laptop maker's spec sheet. Use the cable that came with the monitor if there is one, since a cheap phone cable may charge without carrying a picture.
Above 100W, both ends need USB-C's newer extended power range. A 140W monitor gives 140W only to a laptop built to take it; anything else draws what it can use.
After power, it's an ordinary monitor decision. A 27-inch 1440p screen is the easy middle ground for work. 4K at 27 inches makes text noticeably crisper, which Macs in particular show off, and an ultrawide gives you two documents side by side without a second screen.
Why it’s here. BenQ rates its USB-C port at 65W, enough for most ultrabooks, and pairs it with a 23.8-inch 1080p IPS panel at up to 100Hz. It also has an HDMI port and a DisplayPort input, so a desktop PC can share it.
What it gives up. 1080p across 24 inches is less sharp than the 1440p and 4K screens below, and 65W will lag behind a laptop that came with a bigger charger.
Why it’s here. Also 65W, but on a 27-inch 1440p IPS panel that runs at up to 144Hz, with HDMI and DisplayPort inputs alongside the USB-C. It covers office hours and an evening of games on one screen.
What it gives up. The same 65W ceiling as the BenQ, so it's for ultrabooks rather than power-hungry laptops.
Why it’s here. Sold as a monitor for MacBook Pro and Air, it puts a 27-inch 4K IPS panel behind a USB-C port rated at 90W that also carries the picture and data. 90W covers a wider spread of laptops than 65W.
What it gives up. It runs at 60Hz, so it's a work screen first. There's no DisplayPort socket either; the video inputs are two HDMI 2.0 ports and the USB-C.
Why it’s here. A 34-inch 3440 x 1440 VA panel at up to 180Hz, with 90W USB-C. More width for timelines and side-by-side windows, and enough refresh for games in the evening.
What it gives up. AOC's own figures put the 180Hz on DisplayPort; over HDMI it tops out at 100Hz. VA panels can also smear a little in dark, fast scenes compared with IPS.
Why it’s here. Its Thunderbolt 4 upstream port can supply up to 140W, the most of the five, and the panel is 27-inch 4K at up to 120Hz. A DisplayPort output lets you run a second screen from it.
What it gives up. That 140W only reaches laptops built to take USB-C power above 100W. If yours tops out at 65W or 90W, you're paying for headroom you won't use.
Every value comes from the source its number points to, read on the date shown there. Sizes are the maker’s figure, so a “27-inch” screen may be listed at 26.5 inches viewable.

Usually, yes, just more slowly. Under a heavy load such as gaming or a video export, the battery may still go down while it's plugged in. If that matters to you, choose a monitor that matches your charger's rating.
Use the one that came with the monitor if it has one. For more than 60W the cable has to be rated for 5A (100W), and for 140W it needs to be a 240W extended-power cable. Plenty of cheap USB-C cables are charge-only or stop at 60W.
