Sony Inzone M9 27-Inch 4K Monitor Review: Optimized For PS5

A Sony computer monitor? Now that’s something many enthusiasts aren’t old enough to remember. In the 1990s, Sony marketed a line of Trinitron CRT screens. Their main draw was that they only curved on the vertical axis, which meant they were the closest thing to a flat-screen you could buy at the time. NEC used the same picture tube in its Multisync line, of which I owned a 16-inch version. It was the best CRT monitor I ever owned.

Thirty years later, Sony is well known for its televisions and for the PlayStation 5 (PS5) gaming console. It was inevitable that it would jump into the gaming monitor party with something optimized for that product. The Inzone U27M90 is a 27-inch IPS panel with 4K resolution, 144 Hz, Adaptive-Sync, HDR, extended color AND (drum roll, please), a full-array backlight with 96 dimming zones. Priced at under $1,000, the Sony Inzone U27M90 is making a strong case for inclusion on our best 4K gaming monitor list!
