Refurbished 27-inch 4K UHD IPS monitor

This HP E27k G5 unit arrives in refurbished condition with a 27-inch IPS panel showing 3840 x 2160 resolution at 60 Hz. The 16:9 screen delivers 16.7 million colours and 178° viewing angles horizontally and vertically. It suits office workers and creatives who need sharp text and accurate colour on a single display.

Typical thermals noise and power profile

The panel peaks at 350 nits brightness with a 1000:1 contrast ratio and 5 ms grey-to-grey response when overdrive is active. No built-in speakers are fitted, so acoustic output is limited to faint coil or fan noise at normal brightness levels. Power draw scales with luminance and the active USB hub load but stays within standard desktop monitor ranges.

Connectivity and ergonomics bundle

Video inputs include DisplayPort and HDMI while a single USB Type C port handles data and upstream video. The integrated hub adds RJ-45 Ethernet plus USB Type A ports for peripherals. The stand provides height adjust, tilt, swivel and pivot movement, and the 100 x 100 mm VESA pattern allows arm or wall mounting if the stand is removed.

Questions about this item

How do I attach the stand to the 27" IPS panel and which step is often missed?

Align the stand neck with the rear bracket, press until it clicks, then tighten the captive thumb screw; the step most people skip is securing that screw, which lets the monitor wobble when you adjust height or pivot.

What part will need replacement first during long-term use?

The LED backlight behind the 3840 x 2160 IPS panel dims gradually; after many thousands of hours at 350 nits you may notice reduced brightness and will need a panel swap to restore original output.

What limit appears first when the screen runs continuously at 60 Hz?

Sustained 60 Hz operation keeps the backlight at 350 nits, so the thermal ceiling of the IPS panel is reached first, causing a slow brightness drop before any signal or interface bottleneck occurs.
