The MNN 15.6-inch portable monitor is the budget benchmark in this category, with more than 12,000 ratings. It is a 1080p IPS screen at 60Hz that connects with a single USB-C cable for both picture and power on laptops with video-capable USB-C, or over HDMI with separate power. A smart case folds into a stand. That covers the core use case well: a second screen for spreadsheets, email, video calls and reference documents while travelling or working from a small desk. Like most budget portable monitors it is dimmer than a good laptop screen, and a minority of buyers report issues such as flickering. For a low-cost second screen with a proven track record, it is hard to beat.
