Portable Monitor Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

InnoView is the best-performing portable monitor brand in July 2026, moving 11,000 units across 2 ASINs for 21.2% of Top 10 volume. MNN follows with 10,000 units (19.2%), ahead of Philips Computer Monitors on 8,000 units (15.4%).

Volume is spread across 9 brands, with the top three holding 55.8% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $44.97 to $89.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0CFKLK9JY booked 3K units at $94.99. On the growth side, B0G31WC68M leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B0D44QFCPQ close behind at ▲ 200.0% MoM on 6K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
