At the same 4K resolution, a 27-inch and a 32-inch monitor are two different products. A 27-inch 4K panel packs roughly 163 pixels per inch and practically requires display scaling on Windows; a 32-inch works out to about 138 ppi and stays usable at 100%. The size question is therefore not "how big is my desk" but "do I want sharper text or more usable space".

The fiercest competition on this list sits in the 32-inch OLED band: the Alienware AW3225QF, Samsung Odyssey OLED G8, LG UltraGear 32GS95UE and MSI MPG 321URX are all 4K at 240Hz. Their spec sheets overlap almost completely, so the differences come down to panel type and extras — three use Samsung Display QD-OLED, while LG's uses its own WOLED and can switch to 1080p at 480Hz on a single keypress.

Meanwhile the top-ranked Dell UltraSharp U2725QE needs no high refresh rate at all. It targets people who stare at spreadsheets and code all day: one cable to a laptop carrying power, video and USB peripherals at once. Since remote work became normal, that "monitor as docking station" requirement decides more purchases than refresh rate does.
