pc monitor 28 inch

Most of the 28-inch monitors list 3840 x 2160 (4K / Ultra HD) as the screen resolution.

VESA support varies across listings: several specify a 100 x 100 mm VESA mount standard, while at least one refurbished entry notes no mounting option.

The entries list a 16:9 aspect ratio and identify the screen size as 28 inches.

Some listings explicitly reference HDR support (for example, HDR10). Those listings also often highlight higher brightness values (around 400 nits) alongside the HDR labeling.

Refresh rates among the 4K listings range from 60 Hz up to roughly 150 Hz (some entries list values around 150–152 Hz). Response times are most often 1 ms, with at least one listing showing 4 ms.

Common ports include HDMI and DisplayPort, and some listings also list USB ports. Counts vary: HDMI is shown as 1–2 ports, DisplayPort as 0–2, and USB ports range from 0 up to 4 in the available details.

New listings show multi‑year limited warranties (examples include 2‑year and 3‑year limited warranties), while refurbished listings commonly list shorter coverage such as a 90‑day limited warranty.

Refurbished listings commonly label the condition as "Manufacturer Refurbished" and state that units were inspected, tested, cleaned, or certified to meet quality standards.
