34-inch screens fit a standard desk depth, but resolution changes how close you can sit. Every monitor here measures about 34 inches, is curved and refreshes at 120Hz or more, ordered by refresh rate.
We sorted these picks by refresh rate, resolution and size, working from the makers' own data; if a maker skips HDR, the guide says so, and no figure here comes from our own testing.
