Eighteen and a half inches is the number that decides this one. At 2560 x 1440 and 120Hz, the kksmart is the biggest and sharpest screen in this group, and it's the monitor we keep set up for the Switch 2, because a console on a desk deserves more than a laptop-sized panel. The matte finish and the 500-nit rating do the quiet work: a window behind you doesn't turn the picture into a mirror, which is more than we can say for the glossy panels in this set.
The HDMI port is the one that matters with a docked console — run the dock's cable straight in and you're done. The two USB-C ports cover everything else: video from a device that supports it, and power from a wall adapter or a battery pack. At a listed 22 watts it wants a real charger rather than a laptop's trickle port.
Refresh rate is where the money goes. 120Hz keeps a fast pan from smearing, and it's the most obvious upgrade over the 60Hz screens here. The listed 15ms response time is the one figure that reads slow next to that refresh, so treat this as a smooth panel rather than an esports one — in Switch 2 games, the refresh is what you notice.
All of that counts for little if the thing is a brick to carry, and it isn't. At 2.48 pounds with a quarter-inch top edge, it slides into a laptop sleeve, and the built-in kickstand holds an angle without a separate stand. The two-year warranty is the longest in this group, which means something on a screen that travels. Where it loses is bag space and money: if the monitor has to disappear into a daypack, the S135 is the better answer.

The one we point most Switch 2 players to: an 18.5-inch 2K 120Hz panel that takes the dock's HDMI or a USB-C cable, with the longest warranty here.
