At 32 inches, pixel density decides how sharp text and games look from a normal seat. Every monitor here measures about 32 inches, is 4K and uses a QD-OLED panel, ordered by refresh rate.
We ranked these monitors on refresh rate, resolution and size using manufacturer specifications; where a maker leaves out HDR, we say so rather than guess, since we have not benched them.
