ASUS ZenScreen MB16AHG 15.6" BLACK 2023

Finally, a portable monitor that doesn't feel like a slideshow. If you game on the go, just buy it.

The 144Hz refresh rate is the star here, and it's a genuine surprise in a portable panel. Scrolling through documents and web pages feels fluid, and hooking it up to a gaming laptop or a Steam Deck unlocks a real competitive edge. The 3ms response time keeps ghosting to a minimum. Brightness tops out at 300 nits, which is solid for indoor use but struggles a bit by a sunny window. The 100% sRGB coverage means colors look accurate and not washed out, which is more than we can say for a lot of travel screens.

The ZenScreen's real competition isn't other portable monitors, it's the temptation to just use a tablet as a second screen. An iPad with Sidecar is sharper and brighter, but it can't touch this ASUS for raw gaming smoothness and lag-free response. If you're looking at a dedicated portable monitor, the cheaper ASUS ZenScreen models lack the high refresh rate, making this the clear pick for gamers. The desktop heavyweights like the LG UltraGear 45GX950A-B, ASUS ROG Strix XG27UCDMG, MSI MPG 271QR QD-OLED X50, and Dell UltraSharp U4025QW will crush this in image quality and immersion, but they won't fit in your backpack, and that's the entire point of this thing.

Pricing is all over the map, with a wild $307 spread between vendors. At the low end around $246, this is a steal for a high-refresh portable panel. At the $553 high end, you're getting into territory where you could almost buy a full-sized 1440p gaming monitor. If you're buying, hunt for a deal closer to the $250 mark to make it a no-brainer.

The ASUS ZenScreen MB16AHG is the portable monitor for people who hate portable monitors. Most of them are slow, dim, and feel like a compromise. This one packs a genuine 144Hz refresh rate and FreeSync Premium into a 15.6-inch IPS panel that weighs less than a MacBook Air. It's not perfect, and the 1080p resolution feels a little tight in 2025, but if you need a buttery-smooth second screen for gaming on the go, this is the one to beat.

If you're a creative pro who needs 4K resolution and perfect color accuracy for photo or video editing on location, this isn't your screen. The 1080p panel is sharp enough for work, but it can't compete with a 4K portable OLED. Go grab something like an ASUS ProArt portable display instead.

The ASUS ZenScreen MB16AHG solves the biggest problem with portable monitors by making them fast. It's a niche product that absolutely nails its niche. If you travel with a gaming laptop or a console and refuse to play on a 60Hz screen, this is your new best friend. It's not a desktop replacement, but it's the best travel companion a gamer could ask for.
